Vertical Water -Tube Boiler TYPEAQ-18

GENERAL DESCRIPTION

Instruction K.7140.0

JOI/30S/gs 21 FEB 94 1

-1 -

BOILER DESCRIPTION The AQ-18 boiler is an all-welded vertical water tube boiler and consists in the main of the following components. (Please see figure 1). From the top the steam/water drum, below this drum the furnace room and in the bottom the water drum. STEAM/WATER DRUM The steam/water drum consists of a circular shell limited by two flat tube plates. Because of the increased internal pressure, the tube plates are mutually connected by vertical solid stays. The main connections to the boiler are located at the steam/water drum which is also furnished with necessary internals to ensure an even distribution of feed water and circulating water from the exhaust gas boiler. Access is obtained by the manhole located at the top plate/shell. In the centre of the steam/water drum, the vertical positioned central furnace opening for the steam atomizing burner is located. Accordingly, access to the furnace room is possible from there. FURNACE ROOM The furnace room consists of both internal polygonal shaped membrane walls and of an outer casing wall of the same shape. This construction is gas tight and between the walls the generating tube bank is located. The generating tube bank consists of vertical tubes arranged in a staggered configuration. All the tubes and panel walls are welded on to the tube plates in the steam/water drum and water drum, respectively. The flue gas leaves the furnace room through the deflected tubes at the bottom and passes through the generating tube bank before leaving the boiler.

JOI/4710/jbn 20 DEC 93

" - 2-

An effective circulation in the boiler is achieved by the fact that a number of tubes in the cold area acts as down comers. Access is also possible through the access door at the bottom side as well as the access door provided on the smoke outlet box. Further, access to the generating tubes is possible at the four access doors provided on corners of the casing wall. The bottom tube plate is first covered with coat of insulating refractory and above with castable refractory. WATER DRUM The water drum is constructed similar to the steam/water drum and is supporting the boiler. Inside a heating coil is installed to ensure a quick starting up of the boiler and to maintain a higher temperature during standstill securing the boiler against corrosion. Access is obtained by the manhole located at the shell. For the foundation the boiler is provided with four support feeds, one as fixed food and the others constructed with possibility of thermal expansions. Counter plates are provided for welding to deck.

WATER LEVEL CONTROL

SD9230#17.1

Water level control 1

Description The water level control is a modulating system at this type of boiler. The system is illustrated in Figure 1. The safety device system for too low water level shut down and burner stop consists of a level float switch mounted as an external unit. For measuring and control of the water level, the boiler is equipped with a dp water level transmitter unit, which includes external reference and variable legs, and a dptransmitter. The continuous 4-20 mA output signal from the dp-transmitter is processed in the control system, which provides level alarms/shut downs and control of the regulating feed water valve.

OPERATION DESCRIPTION

3.2.1

Flue gas flov/ The ignition and combustion take place vertically down in the furnace. From here the flue gas flows through the deflected tubes in bottom of the furnace. The flue gas is distributed in the height of the convection section in the cavity at the furnace outlet. In the convection section the flow takes place horizontally through the convection section. After passage of the convection section the flue gas flows horizontally out through the flue gas outlet.

3.2.2

Water-steam flow The heat input is transferred to the water through the heating surfaces in the furnace room and the convection section. The heat transfer in the furnace takes mainly-place by means of radiation,' while convective heat transfer mainly takes place in the convection part. The natural circulation in the boiler provides that water flows from the steam drum and down to the water drum through the tubes least heat effected i.e. generating bank tubes and casing v/all tubes nearest the flue gas outlet. From the v/ater drum the water rises through the other tubes (the furnace membrane walls and the generating bank tubes strongest effected of heat), where an evaporation takes place on the way up through the tubes. The v/ater-steam mixture rises to the steam drum. In the steam drum steam and water are separated, and then the saturated steam leaves the boiler through the steam dryer to the main steam socket.

Lighting-up Before lighting-up of the boiler the whole boiler plant is to be prepared and tested. The preparations and processes mentioned here are normally only carried out in connection with the first lighting-up and after large repairs.

3.3.1

Preparation When the steam plant has been installed it is to be inspected before lighting-up and start. The following description and check list are to be considered as inspection manual. When each single component in this manual has been inspected and found functional, the plant is ready for lighting-up.

3.3.1.1 Furnace In the furnace it is to be tested that refractory at the burner and on the furnace bottom plate is in position and in order. If damage has been noted, this is to be repaired before lighting-up. 3.3.1.2 Burner The boiler is equipped with steam atomizing burner intended for firing with D.O. and H.O. The burner consists of a windbox with guide vanes and throttle, an ignition burner, lance with atomizer nozzles, cone and a gas ring. The arrangement, position and state of these components are to be tested before lighting-up. Please see burner instructions. 3.3.1.3 Combustion air The combustion air volume is adjusted by the throttle in the burner air inlet. Blower rotor and shaft are to be able to turn freely by manual force without binding or scratching. The direction of rotation is to be as marked on the blower casing. C C) O 3.3.1.4 Fuel pipes _ _, w kJ O The diagrams of the fuel pipes in the separate manualjs to "be stildied) thoroughly for understanding of the structure of the system, pipelines and^ w flanged connections are to be absolute tight. \ J x-r-/ v c7 ::

3.3.1.5 Feed water line It is to be tested that all joinings are tight, the valves are placed correctly and that the flow direction through them are right. The feed water regulating valve function is to be tested (please see speciel instruction). 3.3.1.6 Steam lines It is to be tested that the valves have been placed correctly and the flow direction through them are right. All drain lines on the steam boiler to the blow dov/n tank are to be inspected. It is to be ensured that no restrictions betv/een boiler and blow down tank are available. 3.3.1.7 Water level supervision The safety equipment in connection with alarm and disconnection of the firing at low water level and feed water regulation is vital for the operation of the boiler and is therefore to be inspected thoroughly. The water level supervision equipment is to be tested according to the prescribtions of the approval authorities. 3.3.1.8 Safety valves Normally safety valves have been adjusted from the factory. The opening pressure is to be tested at lighting-up (please see instruction). •

3.3.2

Drying of refractory After repair of refractory or other big repair/cleaning it is very important to secure that the refractory is totally dry before lighting-up. In order to secure that.the refractory is totally dry and formation of cracks does not take place, the following procedure is to be used: 1.

The boiler is to be filled v/ith water to normal water level with open air relief valve. ^ ^ --'

OPERATION

3.4.1

Generel operation manual

3.4.1.1 Levels for HW. LW and LLW At high water level (HW) an alarm is released and the feed pumps are stopped. In this way it is secured that the water level will not be so high that the steam quality is damaged. At low water level (LW) an alarm is released and the firing is stopped. In this way damage, due to non-cooling, is avoided. At low low water level (LLW) an alarm is released and further safety stop of the lighting-up is made. 3.4.1.2 Feed water The water level in the boiler is automatically regulated by a feed water regulator, which is to be adjusted in such a way that the water leve.l is maintained at normal water level. The same is to be aimed at by manual operation, if any. 3.4.1.3 Combustion control The combustion control is to be adjusted according to separate instruction (please see that instruction), so that optimum combustion is obtained. 3.4.1.4 Temperature The temperatures, exhaust gas and feed water are to be supervised with regard to trouble-shooting.

CLOSING DOWN

3.5.1

General It is possible to close the boiler down at any load, without special preparations, if absolute necessary. When closing down sudden temperature and pressure drops are to be avoided, as they can expose accessories, pipe lines and the boiler plant to inadmissible temperature gradients.

3.5.2

Procedure for closing down #

When obtaining minimum load regulating circuits (feed water, steam pressure) are to be disconnected. The burner is to be stopped. The v/ater level is to be kept at the centre line of the v/ater level indicator until the boiler stops producing steam. The feed pump is to be stopped and valves on the feed water pipe are to be closed. The main steam valve and other valves on the pressure system are to be closed. When closed down for a long time boiler and economizer are to be preserved, both from the water and exhaust gas side. Regarding preservation, please see the next paragraph. 3.5.3

Preservation of boiler during standstill Steam boilers which are taken out of operation for a short or long time, should be preserved in order to avoid corrosion damage.

3.5.3.1 Preservation of the flue aas side The soot deposited on the flue gas side during operation can contain sulphuric acid and water, which can result in corrosion. Therefore the flue gas side is to be preserved in the following way: y /' \ v.../

Dry preservation If the water side of the boiler is preserved by keeping the super pressure, the boiler temperature will keep the flue gas side dry in the whole standstill period. In connection with the other v/ater side preservation methods, the exhaust gas side is to be closed as tight as possible after boiling out. 3.5.3.2 Preservation of water/steam side Presence of oxygen may result in corrosion, which shows as "pittings" inside surfaces. Preservation can be made in the following ways: Dry preservation By this method the boiler is totally to be emptied of v/ater and boiled out. The boiler is emptied of water by blov/ down of the boiler with a pressure of 3-5 bar, then the boiler is to be opened and drained for remaining water, if any. Boiling out of the boiler can be carried out by circulation of dried air from an air blower or by placing a bag of silicagel in the boiler drums. Alternatively some inhibitor can be supplied to the boiler drums after cooling 'down and thorough draining, and then the boiler is totally to be closed. Wet preservation Wet preservation is carried out by filling the water totally with treated feed water added oxygen binding agent in a quantity corresponding to 100-200 ml/m3 hydrazine or sulphite. At the same time the pH-value is to be adjusted to 10-10.5. When the boiler is lighted-up again, the water is to be drained off until normal water level has been established. The boiler can now be lighted-up in usual way. Nitrogen preservation

Inspection For inspection on the flue gas side, access to the furnace is possible through the door at the bottom of the furnace. For inspection of the flue gas side of the tubes there are several possibilities: Through the access door mentioned above, at the flue gas outlet from the flue gas channel, and through the four (4) inspection openings at the bottom of the tube section, placed at the panel wall corners. From here it is possible to see, whether the tubes are covered with soot or possible to locate a damaged tube in the area. For inspection inside the steam drum and water drum, manholes in both shells are available, through which access to the internal parts is possible. Inside the drums it is possible to see all the details and to plug some tubes, if necessary.

3.6.3

Water washing Generally there will be a selfcleaning effect of the generating tube bank due to a high flue gas velocity. However, after long term operation, especially during part load, deposits can be formed on the tubes, which can be removed by means of either soot blov/ing (with air) or water washing. During combustion of oil of a poor quality or with a reduced combustion quality, deposits can be formed, which cannot be removed by means of normal soot blowing. The heating surface is to be washed with an alkaline solution (10% soda solution) and/or freshwater. As most of the deposits mainly consist of non-soluble particles, which are held together by a water soluble bonding material, water under pressure will have the following purposes: a) b)

to dissolve the bonding material to wash the loosened insoluble remainders away.

The AQ-18 boiler is provided with a sufficient number of fixed cleaning sockets in two levels, facilitating removal of soot deposit, when necessary. Water washing is carried out with a manually operated lance, which is to be mounted on a handle for a high pressure washer (see fig. 1). -By water washing the boiler must be out of operation and max. boiler temperature is to be 110°C. By v/ater washing the following procedure is to be used (fig. 2): 1)

At bottom of the boiler furnace a drain has been mounted, which is to be opened and connected to an accumulation tank.

2)

On the boiler walls (panel walls) a number of cleaning sockets have been mounted in different levels. The threaded socket is to be unscrewed from these and the lance is to be led.through the cleaning socket. Q

3)

The handle is to be activated in order to lead high-pressureCwater to the lance. ,o ^

4)

Lead slowly the lance to full depth and back again. (Rèpeat) thiP process several times for approx. 2 minutes, in'each' socket, to) ensure good cleaning.

j

AALBORG INDUSTRIES

5)

The cleaning is to be repeated for all cleaning sockets and caps to be mounted after cleaning.

6)

After cleaning in all the sockets, soot blowing can also be done through the inspection doors at the bottom of the tube section. The doors are removed and the lance is to be inserted between the convection tubes. Cleaning is done in the same way as described above. After cleaning the doors are to be mounted again.

7)

After water washing the refractory at the furnace bottom must be cleaned with alkaline water, as the water is very corrosive. It has to be observed that all washing v/ater and removed deposits are taken out of the boiler. If water washing is started, it has to be continued in order to remove all deposits, as some deposits get hard and difficult to remove, v/hen they get wet and later dry out.

8)

The plant is to be boiled out immediately after the v/ater washing has been completed in order to avoid damage on refractory and heating surfaces. The boiler is to be lighted-up and pressure to be raised, as described in paragraph 3.3 "Lighting-up".

When the water v/ashing has been started it has to be carried through, so that all deposits are removed, as some types of coatings hardens and get difficult to remove, when they first have been saturated and then dry out. The plant is to be boiled out immediately after the v/ater v/ashing has been completed in order to avoid damage on refractory and heating surfaces. The boiler is to be lighted-up and pressure to be raised as described in paragraph 3.3 "Lighting-up".

Repair

3.6.4.1 Instruction for plugging of tubes In case of leakage on a boiler tube, the burner is to be stopped and the pressure to be removed from the boiler. If the tube in question cannot be located immediately, the boiler is to be set on pressure by means of the feed water pump, so that the leakage will indicate the tube which has been damaged. The boiler is to be emptied of v/ater and the manhole covers in the steam drum and the water drum are dismantled. When a damaged tube has been located, the tube is to be plugged with a conical tube plug. Before the conical tube plug is mounted, the tube ends are to be cleaned inside, so that no deposits are present in the tube. When a tube has been plugged, a new tube should be mounted as soon as possible. When tubes are plugged, the efficient heating surface is reduced and the boiler efficiency v/ill go down.

AALBORG INDUSTRIES

Plugging of furnace tubes When a furnace tube has been plugged, the furnace side of the damaged tube is to be cut vertically along the connections with the fins between the tubes in the membrane wall (sketch no.1). Inside the rest of the tube and on the fins next to the damaged tube a number of anchors of heat resistant or stainless steel are to be welded on. Hereafter refractory is to be placed against the damaged tube and the neighbouring fins in the full height in the furnace. Plugging of convective tubes and outside membrande wall tubes Sketch no. 2 shows plugging of convection tubes and tubes in outside membrane walls. When the tube has been located, it is to be plugged in both ends. After this operation the boiler can be filled up with water and the normal boiler use can continue, until the tube can be replaced by a new tube. 3.6.4.2 Repair of refractory Normally, routine maintenance is carried out of all refractory. In case of often lighting-ups and closing downs of the plant increased maintenance of the refractory is required. As the refractory not is elastic, a sudden load can make it crack. Peeling can occur, if pieces of the refractory is loosened. Peeling is acceptable, provided that the material loss does not exceed more than the half of the thickness of the original casting. Peeling is to be patched with own refractory at the next closing down of the boiler. Normally, cracks in the refractory do not need repair, unless the size and extent cause direct fatigue of the refractory. Light cracks indicate that the crack is a natural expansion and these are not to be repaired. O

Dark cracks are to be repaired, however, it is pointed out that expansion v cracks in time get darker. '\J

Feed and boiler water 1

General Note: The recommended feed and boiler water characteristics are only valid for boilers with a working pressure below 20 barg. There is a number of ways to produce good quality feed water for boiler plants. Methods such as e.g. reverse osmosis plants or ion exchange plants produce good quality distillate. Also evaporators generally produce good distillate. The important thing is that the distillate used should be clean and without foreign salt contamination. In practice most distillates used contain minor parts of various salt combinations which can and must be chemically treated away. Furthermore, the distillate may contain dissolved gases like for example oxygen (O2) and carbon dioxide (CO2) which may lead to corrosion in the boiler, steam, and condensate system. Important: Boiler and feed water must be chemically treated in order to avoid corrosion and scaling in the boiler.

Layout of the treatment system The condition of the feed and boiler water is an essential part of the boiler operation and operation philosophy. The design and construction of the treatment system should therefore be considered carefully during layout of the plant. Aalborg Industries gives some general requirements and recommendations regarding the conditions of the feed and boiler water. However, there is several ways to obtain this results, or similar, by using different treatment systems. The following should therefore be considered already at the layout stage: — Choose the treatment system that should be used. — Present the condensate and feed water system to the supplier of the treatment system and inform about the operation philosophy of the plant. — Let the supplier indicate where the injection points should be located and also inform if special equipment is required. — Let the supplier inform about which test facilities is needed. — Purchase the recommended equipment and install it in the correct way. — Use the treatment system as soon as the boiler is taken into operation.

Feed and boiler water characteristics The following text regarding feed and boiler water treatment is the normal recommendations given by Aalborg Industries. These recommendations should be followed strictly in order to have the best working conditions for the boiler plant and to extend the working life of the plant. The requirements/recommendations of the various values for feed and boiler water are listed in Table 1 below.

Table 1 If hydrazine (N2H4) is not used, sodium sulphate (Na2S04) can be used instead, and the excess should be 30 - 60 ppm. In cases where other kinds of oxygen binding agents are used, it is recommended that an excess of oxygen binding agents can be measured and indicates that no oxygen has been dissolved in the boiler water. If it is requested to measure the content of dissolved oxygen directly, it is recommended to keep the value < 0.02 ppm. In addition to the above values, the various water treatment companies will add further demands, depending on the method used for treatment of feed and boiler water. However, the most important point is that the above values or their equivalents are observed and that a regular (daily) test of feed and boiler water is carried out.

Feed and boiler water maintenance The following are recommended water maintenance instructions. More exact details concerning analyses and blow downs should be set up together with the supplier of chemicals for water treatment. 4.1.1 Daily Step A: Analyses of feed and boiler water. 4.1.2 Weekly Step A: Skimming (surface blow down) according to analyses, but at least once per week (2 minutes with fully open valve). Step B: Blow down (bottom blow down) according to analyses, but at least once per week (each blow down valve 1 minute in low load condition). 4.1.3 Monthly Step A: Check the functions for salinity and oil detection systems. 4.1.4 Every six months Step A: The boiler water side (interior) must be carefully inspected at least twice a year. 4.1.5 Yearly Step A: Check of the water side of the boiler and hotwell/deaerator for corrosion and scaling. Step B: Check the chemical pump unit.

Treatment systems / injection points In the following tables and illustrations a number of different feed and boiler water treatment systems are shown together with the recommended location for the injection point of the individual chemicals as stated by the manufacturer. The general information regarding the injection point principle can be used as guidelines for the most common systems. But should there be any doubt for a specific system the manufacturer/supplier should be consulted in order to obtain the correct result. Notes for tables/illustrations: •

Note No. 1: the preferred injection point of chemicals stated by the manufacturer/supplier.

•

Note No. 2: the alternate injection point of chemicals stated by the manufacturer/supplier.

•

Note No. 3: Valid for modulating feed water systems.

•

Note No. 4: valid for on/off operating feed water systems. The chemical pump starts/stops together with the feed water pump.

•

Note No. 5: valid for two boiler installation. Control of the chemicals in question work properly at an equal load condition (feed water flow) on the two boilers.

How to use the tables: The tables can be used in different ways but the main idea is to do following: Step A: Discover which manufacturer and type of chemicals that should be used for the actual boiler plant. Step B: Use the name of the manufacturer and type of chemicals to select which tables that can be used. Step C: Check the flow diagrams (Figure 1, Figure 2, or Figure 3) to find a diagram that matches the actual boiler plant. Step D: Find in the selected tables the table which includes the matching diagram. Step E: If more than one table is found to match the actual boiler plant in question it is recommended to use the method/table which includes note No. 1. Step F: If no table is found to match the actual boiler plant in question it is recommended to seek assistance by the chemical manufacturer/supplier.

Maintenance and start-up of boiler A regular inspection of the safety valve is recommended at least once a year. Some media and appliances require a more frequent inspection, this is according to the experience of the supplier. Warning: Before handling and dismantling of the safety valve ensure that the system is NOT pressurised! Before lighting-up the boiler the pipe connections must be thoroughly cleaned for dirt and foreign bodies. Language UK

SAFETY VALVES

OM6040#01.0

INDUSTRIES

If the valve is not completely tight, which often happens after starting up the plant, this is usually caused by impurities between the seat and the cone. In order to remove these impurities the valve must be heavily blown out by means of the lifting device. If the valve is not tight after several blows, it may be due to the fact that a hard foreign body has got stuck between the cone and the seat, and it will then be necessary to dismount the valve for overhaul. Warning: In case of a leaking safety valve the valve must be inspected and over-hauled at earliest possible opportunity. It must be ensured that the boiler is totally depressurised before dismounting the valve.

Note: Before dismantling the safety valve in the workshop the position of the adjusting screw must be measured and noted which will facilitate the adjustment later when the valve is to be adjusted when in service. If the facings between the cone and the seat have been damaged, they must be grinded. Step A: The cone can be grinded against a cast iron plate, using a fine grained carborundom stirred in kerosene. Step B: The seat in the valve body can be grinded in the same way by using a cast iron punch of suitable size.

Note: Never use the cone itself when grinding the seat.

Warning: The spindle and the valve cone must always be secured against turning as the seat and the cone may thus be damaged. Step C: Before assembly the valve must be thoroughly cleaned, and all traces of grinding material and impurities must be removed. When the valve has been mounted the boiler is commissioned, and the valve is then checked for leakage and adjusted to the set pressure. Step D: The adjustment screw is secured by means of its lock nut, and the valve is sealed.

2.2 Routine check The following should be regarded as recommendations of routine checks on the safety valves, in order to keep a proper functioning.

Yearly Step A: The safety valve should be tested in operation by raising the boiler pressure. Step B: Expansion and exhaust pipe should be examined at the same time. Monthly Step A: Examine the safety valves for any leaking, such as: •

Is water seeping from the drain plug at the valve body?

•

Is the escape pipe hot due to seeping steam from the valve seat?

Step B: Examine the drain and expansion device at the escape pipe. Step C: Examine the lifting gear device, i.e. clean up and grease all sliding parts.

Adjustment and dismantling Safety valves are delivered with the required spring setting and sealed against unauthorised adjustment. Adjustments are only allowed in the spring margins. Outside the margin a new spring is required. The pressure in a system should not exceed 90% of the set pressure. All item nos. mentioned in the following sections refer to Figure 2.

TEMPORARY LOCKING OF A SAFETY VALVE

OM6040#02.0

Temporary locking of a safety valve 1

General During commissioning work or later tests of the opening pressure for the safety valves, only one safety valve should be checked at a time. This means that the other safety valve must be locked. The following instruction describes the temporary locking of a safety valve.

1.1 Procedure for locking of a safety valve Step A: Remove the bolt (39) and split pin (40), see Figure 1. Step B: Remove the lifting lever (41). Step C: Unscrew the screw (38) and break the lead seal (23), if provided. Step D: Unscrew the cap (29). Step E: Place one or two bolts (48) on top of the spindle. The height of the bolts should be approximately 1-2 mm higher than the normal distance between the top of the spindle and the inside top of the cap (29). Step F: Carefully screw on the cap until the spindle and bolts are locked. The safety valve will be completely locked when the bolts cannot be moved anymore. Step G: The other safety valve can now be tested without any interference from the locked safety valve.

1.2 Procedure for unlocking of a safety valve

Warning: As soon as the test procedure for the safety valve has been carried out the locked safety valve must be unlocked. Step A: Unscrew the cap (29) and remove the bolts (48). Step B: Mount the cap (29) again and screw in the screw (38). Step C: Mount the lifting lever (41), bolt (39), and split pin (40). Step D: Provide the safety valve with a lead seal (23), if necessary. This depends on the local rules of the classification society.

DP WATER LEVEL TRANSMITTER UNIT

OM8210#16.1

INDUSTRIES

dp water level transmitter unit General The dp water level transmitter unit controls and supervises the water level in the boiler. The complete unit is installed in a vertical position and connected to the boiler sockets, provided for this purpose, by means of shut-off valves (see Figure 1). The dp water level transmitter unit includes reference leg, variable leg, transmitter connection valves mounted on a manifold, and a differential pressure transmitter. The differential pressure transmitter converts the detected water level into an analogue signal (4-20 m A) which is transmitted to the control system. The signal can also be used for remote level indication in the engine control room. Illustration of the dp water level transmitter unit Shut-off valves Filling plug Reference leg

Drain valve

Equalising valve dp-transmitter—

The differential pressure transmitter is installed with the process connections upward to prevent trapping of air. The pipes are mounted with continuous fall (at least 5°) from the boiler connections to the transmitter also to prevent trapping of air. The reference impulse leg (upper connection point) is connected to the high pressure connection (+), and the variable impulse leg (lower connection point) to the low pressure connection (-). Note: The dp water level transmitter unit or any part of it must not be insulated to ensure the correct function.

Commissioning 2.1 Initial commissioning Before the boiler is pressurised and started for the first time some initial commissioning procedures can be performed with regard to the valves of the dp water level transmitter unit. The shut-off valves, transmitter connection valves, and equalising valve should be operated in the following sequence during the initial commissioning: Step A: Initial setting; all valves of the dp water level transmitter unit closed (see Figure 1). Step B: Open the equalising valve located on the valve manifold. Step C: Unscrew the filling plugs for the reference leg and variable leg. Fill the legs with feed water. Step D: Open the transmitter connection valve and venting facility on the reference leg side of the transmitter. Step E: Close the venting facility on the reference leg side of the transmitter when no more air escapes. Step F: Open the venting facility on the variable leg side of the transmitter. Step G: Close the transmitter connection valve on the reference leg side of the transmitter when no more air escapes. Step H: Open the transmitter connection valve on the variable leg side of the transmitter. Step I: Close the venting facility on the variable leg side of the transmitter when no more air escapes. Step J: Close the transmitter connection valve on the variable leg side of the transmitter. Step K: Close the equalising valve. Step L: Refill the legs with feed water and screw on the filling plugs for the reference leg and variable leg. Step M: Open both transmitter connection valves fully.

2.2 Commissioning of the differential pressure transmitter The differential pressure transmitter can be commissioned either through "blind calibration" or "live calibration". In the following sections both methods are described. Language UK

Page 2/10

AALBORG


OM8210#16.1

INDUSTRIES

2.2.1 Blind calibration Blind calibration of the differential pressure transmitter can be performed if no pressure source is available. This means when the boiler cannot be operated at normal working pressure and the water level cannot be increased/decreased. The "start of scale" and "full scale" differential pressures are calibrated on the basis of calculated values. The start of scale value should be calibrated to obtain a 4 mA output signal from the transmitter when the water level is at the lower connection point and the full scale value to obtain a 20 mA output signal when the water level is at the upper connection point. To ensure an accurate calibration it is necessary to take the density difference between the water in the reference leg and in the boiler into consideration when calculating the differential pressure values. 4 mA output signal from the differential pressure transmitter: — When the water level in the boiler is at the lower connection point the pressure difference over the transmitter is equal to the height between the connection points (column of water) corrected with the density of the water in the reference leg. The value must be specified and entered in engineering unit, e.g. in mm H 2 0. 20 mA output signal from the differential pressure transmitter: — When the water level in the boiler is at the upper connection point the pressure difference over the transmitter is equal to the height between the connection points corrected with the density difference between the water in the reference leg and in the boiler. The value must be specified and entered in engineering unit, e.g. in mm H 2 0. Figure 2 indicates the calculation procedures of the differential pressures. As standard it is assumed that the temperature in the reference leg (condensate receiver) is 40°C. Table 1 shows the calculated values for some standard heights between the connection points. If the actual boiler plant does not fit any of the standard calculations the specified calculated values can be entered in the table for calibration record purpose. If the boiler plant is intended to operate at different set points (high/low pressure mode) the differential pressure transmitter must be calibrated so that the minimum indicated "Too low water level" on the control system not is lower than the actual "Too low water level" mark. Because of the density difference in the boiler water at different working pressures/temperatures the indicated water levels will not be identical. This means that the differential pressures for start of scale and full scale should be calculated using the parameters from operation in high pressure mode. When the differential pressures corresponding to the "start of scale" and "full scale" have been calculated carry out the following work steps (please also see the specific instruction for the differential pressure transmitter): Step A: Unscrew the screws that hold the protective cover of the differential pressure transmitter for access to the push buttons. Step B: Use the "M" key to select modes on the differential pressure transmitter. When a mode is selected, the keys T and i are used to change the mode value.

Language UK

OM8210#16.1

INDUSTRIES

Step C: Set the values in mode 4 (electrical damping), 9 (output in error situation), 10 (pushbuttons functions), 11 (characteristic), 13 (value displayed), and 14 (engineering units). In mode 14 select e.g. "mm H20" as engineering units. Step D: Select mode 5 using the "M" key. Step E: Use the t or i key to set the start of scale in the selected engineering unit. If mm H2O is selected as engineering units, then set the start of scale to the calculated value in mm H2O (differential pressure at 4 mA). Step F: Press both the t and -l keys simultaneously for about 2 seconds, and the start of scale is set to zero (in the selected engineering unit). Step G: Select mode 6 using the "M" key. Step H: Use the T or 4 key to set the full scale in the selected engineering unit. If mm H20 is selected as engineering units, then set the full scale to the calculated value in mm H2O (differential pressure at 20 mA). Step I: Press both the t and X keys simultaneously for about 2 seconds, and the full scale is set to the upper limit (in the selected engineering unit). Step J: Mount the protective cover of the differential pressure transmitter again.

2.2.2 Live calibration Live calibration of the differential pressure transmitter can be performed when a pressure source is available. This means when the boiler can be operated at normal working pressure and the water level can be increased/decreased. The "start of scale" and "full scale" output signals of the differential pressure transmitter are set during actual operating conditions. It is therefore not necessary to take the density difference between the water in the reference leg and in the boiler into consideration. However, if the boiler plant is intended to operate at different set points (high/low pressure mode) the differential pressure transmitter must be calibrated so that the Language UK

minimum indicated "Too low water level" on the control system not is lower than the actual "Too low water level" mark. Because of the density difference in the boiler water at different working pressures/temperatures the indicated water levels will not be identical. This means that the differential pressure transmitter should be calibrated when the boiler plant operates in high pressure mode. When the boiler operates at normal working pressure carry out the following work steps (please also see the specific instruction for the differential pressure transmitter): Step A: Unscrew the screws that hold the protective cover of the differential pressure transmitter for access to the push buttons. Step B: Use the "M" key to select modes on the differential pressure transmitter. When a mode is selected, the keys T and i are used to change the mode value. Step C: Set the values in mode 4 (electrical damping), 9 (output in error situation), 10 (pushbuttons functions), 11 (characteristic), 13 (value displayed), and 14 (engineering units). In mode 14 select "mA" as engineering units. Step D: Ensure that the boiler cannot be filled with feed water by closing the feed water valves or stopping the feed water pumps. Step E: Slowly decrease the water level in the boiler until the lower connection point is reached (socket centre line of the variable leg). The water level can be decreased by means of the blow down valves. Step F: The upper and lower connection points will normally be beyond the visual indication area of the water level gauges. It is therefore impossible to see when the water level is at these points. However, the rising/falling rate of the water level can be controlled, by throttling the feed water valves/blow down valves. By clocking the rate it can be calculated when the water level has reached the connection points. Step G: Select mode 2 using the "M" key. Step H: Set the output current corresponding to the start of scale using the Î and i keys. Or set the output current to 4 mA by pressing the t and i keys simultaneously for about 2 seconds. Step I: Slowly increase the water level in the boiler until the upper connection point is reached (socket centre line of the reference leg). The water level can be increased by means of the feed water pumps. Step J: When the water level is increased operate the burner so that the boiler pressure is kept at normal working pressure. Step K: Select mode 3 using the "M" key. Step L: Set the output current corresponding to the full scale using the T and i keys. Or set the output current to 20 mA by pressing the T and i keys simultaneously for about 2 seconds.

Step M: Mount the protective cover of the differential pressure transmitter again.

2.3 Final commissioning During final commissioning a function test of the dp water level transmitter unit must be performed before the boiler plant is put into normal operation. The purpose of the function test is to check that the output signals from the differential pressure transmitter are correct. Furthermore, it should be checked that the connected alarms/shut downs and control functions are operational. The boiler should be operated at normal working pressure during the test to provide for correct indications. When the boiler is at normal water level and the burner is in operation, carry out the following work steps: Step A: Slowly increase the water level in the boiler by forcing operation of the feed water pump until the water level has risen to the "High water level" level. The control system should indicate an alarm, (if provided).

Note: Note that shut downs, alarms, and cut out functions can be delayed via timers in the control system. Step B: Increase the water level somewhat until the "Too high water level" mark is reached. The burner should stop, and a shut down should be indicated on the control system, (if provided). Step C: Increase the water level somewhat until the upper connection point is reached (socket centre line of the reference leg). Check that the output signal from the differential pressure transmitter is at 20 mA or the full scale value in the selected engineering units. Step D: The upper and lower connection points will normally be beyond the visual indication area of the water level gauges. It is therefore impossible to see when the water level is at these points. However, the rising/falling rate of the water level can be controlled, by throttling the feed water valves/blow down valves. By clocking the rate it can be calculated when the water level has reached the connection points. Step E: Ensure that the boiler cannot be filled with feed water by closing the feed water valves or stopping the feed water pumps. Step F: Decrease the water level in the boiler by means of the blow down valves until the water level has fallen to the " Low water level " level. The control system should indicate an alarm. Step G: Decrease the water level somewhat until the "Too low water level" mark is reached. The burner should stop, and a shut down should be indicated on the control system. Step H: Decrease the water level somewhat until the lower connection point is reached (socket centre line of the variable leg). Check that the output signal

from the differential pressure transmitter is at 4 mA or the start of scale value in the selected engineering units. Step I: After completion of the function test open the feed water valves or start the feed water pumps.

Operation and maintenance Attention: Both shut-off valves between the boiler and impulse legs must always be fully open and the reference leg must be totally filled with water during normal operation of the boiler. To ensure a safe and reliable operation of the boiler plant check the dp water level transmitter unit whenever an opportunity occurs by comparing the water level indicated by the control system with the level indicated in the water level gauges. A great difference in the water levels may indicate blocked connections to the differential pressure transmitter. Therefore it is recommended to blow-through the impulse legs and connection pipes frequently. The blow-through procedures can be performed, e.g. in connection with stopping the boiler plant, in order to get rid of dissolved particles that could settle during the stop periods. In case of prolonged standstill the dp water level transmitter unit should be checked for the correct function before the boiler plant is restarted. 3.1.1 Blow-through procedure of the impulse legs The blow-through procedure should be performed as describe below when the boiler plant is in operation and in steady load condition. The procedure should be carried out at least once each month. When the blow-through procedure is carried out, it is very important that the water level in the boiler is carefully and continuously supervised by the ship engineering personnel. The feed water control valve must be operated manually, if necessary. Step A: Isolate the differential pressure transmitter by closing the two transmitter connection valves in the manifold. The equalising valve must remain closed during the blow-through procedure and normal operation. Step B: Slowly open the drain valves of the impulse legs, and allow the legs to blow-through for a few seconds. Step C: Close the shut-off valve for the reference leg. Step D: Close the drain valves again when the reference leg is completely depressurised. Step E: Unscrew the filling plug of the reference leg and fill the leg with feed water. Step F: Screw on the filling plug and slowly open the shut-off valve for the reference leg. Step G: Open the two transmitter connection valves in the manifold. Language UK

Step H: After performing the blow-through check that the dp water level transmitter unit and feed water control valve are fully operational. In case of contaminated boiler water, e.g. sludge, mud, etc., the blow-through procedure of the impulse legs must be done more often. 3.1.2 Blow-through procedure of the connection pipes The blow-through procedure should be performed as describe below when the boiler plant is stopped, but still pressurised. The procedure should be carried out at least once each year. Step A: Open the venting facilities located on the valve manifold for the impulse legs. The transmitter connection valves must remain open and the equalising valve closed during the blow-through procedure. Step B: Close the venting facilities on the valve manifold when only clean water escapes. Step C: Close the shut-off valve for the reference leg. Step D: Slowly open the drain valve of the reference leg. Step E: Close the drain valve again when the reference leg is completely depressurised. Step F: Unscrew the filling plug of the reference leg and fill the leg with feed water. Step G: Screw on the filling plug and slowly open the shut-off valve for the reference leg. In case of contaminated boiler water, e.g. sludge, mud, etc., the blow-through procedure of the connection pipes must be done more often. 3.1.3 Function test of the dp water level transmitter unit During normal operation of the boiler plant a function test of dp water level transmitter unit should be carried out at least once each month. The purpose of the function test is to check that the connected alarms/shut downs and control functions are operational. The boiler should be operated at normal working pressure during the test to provide for correct indications. When the boiler is at normal water level and the burner is in operation, carry out the following work steps: Step A: Slowly increase the water level in the boiler by forcing operation of the feed water pump until the water level has risen to the "High water level" level. The control system should indicate an alarm, (if provided).

Note: Note that shut downs, alarms, and cut out functions can be delayed via timers in the control system. Step B: Increase the water level somewhat until the "Too high water level" mark is reached. The burner should stop, and a shut down should be indicated on the control system, (if provided).

Step C: Ensure that the boiler cannot be filled with feed water by closing the feed water valves or stopping the feed water pumps. Step D: Decrease the water level in the boiler by means of the blow down valves until the water level has fallen to the "Low water level" level. The control system should indicate an alarm. Step E: Decrease the water level somewhat until the "Too low water level" mark is reached. The burner should stop, and a shut down should be indicated on the control system. Step F: After completion of the function test open the feed water valves or start the feed water pumps.

LEVEL FLOAT SWITCH

OM8210#15.1

Level float switch 1

General The level float switch of type RBA 24 supervises the water level in the boiler. It is installed in a vertical position and connected to the boiler sockets, provided for this purpose, by means of shut-off valves. A float and float rod carry a transmitting magnet which runs in a stainless steel transmitting tube. The transmitting magnet operates the externally installed magnet switches. When the magnet switches have been triggered, they remain in that position until trigged again. Figure 1 illustrates the level float switch. Illustration of the level float switch Shut-off valves

2.2 Adjusting the switch point The switch point of the level float switch should be pre-adjusted before the boiler is pressurised and started for the first time. Step A: Open both shut-off valves and close the drain valve. Step B: Open the feed water valves and the air valve. Fill the boiler with evaporated water until the "Too low water level" mark has been reached and adjust the magnet switch to the switch point. It should be moved in upwards direction until the switch is trigged and secured in this position. The magnet switch must rest against the transmitting tube.

Note: If the temperature difference between the boiler and feed water exceeds approximately 50°C, the boiler must be filled very slowly. When filling a pressure less boiler, the shut-off valve after the feed water pump must be throttled. Otherwise the pump motor will be overloaded.

2.3 Function test During commissioning a live test of the level float switch must be carried out before the boiler is put into normal operation. The purpose of the live test is to check that the shut down for too low water level and cut out function of the burner is operational. When the boiler is pressurised and the burner is in operation carry out the following work steps: Step A: Slowly decrease the water level in the boiler by means of the blow down valves until the water level has fallen to the "Too low water level" mark. Ensure that the boiler is not refilled with water by closing the feed water valves. Step B: Note that both the shut down and cut out function is delayed via a timer in the control panel. Step C: Adjust the switch point, if necessary. Step D: After completion of the function test open the feed water valves fully and raise the water level to the normal level.

Operation and maintenance Attention: Both shut-off valves must always be fully open during normal operation of the boiler. To ensure a safe and reliable operation of the boiler plant check the level float switch whenever an opportunity occurs by comparing the magnetic switch function with the level indicated in the water level gauges.

LEVEL FLOAT SWITCH

OM8210#15.1

A great difference in the water levels may indicate either blocked connections to the float chamber or a water filled level float. Therefore it is recommended to blowthrough the level float switch and connection pipes frequently (see below). The blow-through procedures can be performed, e.g. in connection with stopping the boiler plant, in order to get rid of dissolved particles that could settle during the stop periods. In case of prolonged standstill the level float switch should be checked for the correct function before the boiler plant is restarted.

3.1 Blow-through procedure The blow-through procedure with cleaning of the float chamber should be performed as describe below when the boiler plant is in operation. The procedure should be carried out at least once each week. Step A: Slowly open the drain valve to fully open position, and allow the chamber to blow-through for a few seconds. Step B: Close the drain valve again. In case of contaminated boiler water, e.g. sludge, mud, etc., the blow-through procedure of the level float switch must be done more often.

3.2 Blow-through and test procedure The blow-through procedure with test of the shut down and burner cut out function should be performed as describe below when the boiler plant is in operation. The procedure should be carried out at least once each month. Step A: Fully close the upper shut-off valve. Step B: Slowly open the drain valve to fully open position, and allow the chamber to blow-through for a few seconds. Step C: Then close the drain valve and open the upper shut-off valve again. Step D: Fully close the lower shut-off valve. Step E: Slowly open the drain valve to fully open position, and allow the chamber to blow-through for a few seconds. As the water level falls inside the float chamber check that the shut down function is activated and the burner cuts out. Please note that both the shut down and cut out function is delayed via a timer in the control panel. Step F: After performing the blow-through and test procedure close the drain valve and open the lower shut-off valve again. In case of contaminated boiler water, e.g. sludge, mud, etc., the blow-through procedure of the level float switch must be done more often.

3.3 Cleaning The float chamber, transmitting tube, and transmitting magnet must be opened, checked, and cleaned from dirt at least once a year. Carry out the following work procedures:

CONTROL VALVES, TYPE 470/471

OM6010#02.0

INDUSTRIES

Control valves, type 470/471 1

General This type of control valve is suited to regulate fluids, gases and steams. The valve plug is normally a parabolic plug, but can also be supplied in a perforated design. Both types of plugs can have either linear or equal percentage flow characteristic. The flow direction for parabolic plugs is always against the closing direction. However, with perforated plugs for steam and gases, it is in the closing direction. If a valve with a perforated plug is operated by means of a pneumatic actuator with the flow in the closing direction, the pneumatic actuator should have a stronger thrust force. This is necessary to prevent thumping near to the closing position. All control valves can be fitted alternately with manual-, pneumatic-, electric- or hydraulic operation devices.

Operation 2.1 Fitting instructions The valve should be inserted so that the spindle has a vertical position together with the actuator. The valve can also be tilted to a maximum horizontal position if the installation point does not allow any better condition. To guarantee a disturbance free function of the control valve, the inlet and outlet stretches of the piping should be of straight piping length (min. two times the pipe diameter by inlet and six times by outlet). The piping should be rinsed to clear out any pollution, welding beads, rust, etc. before inserting the control valves. A strainer should be fitted in front of the control valve to catch the remaining particles. Bolts should be tightened after taking into operation. The flow direction is signalled by an arrow on the valve body. The valves should be insulated against high temperatures to guard the actuator. 2.2 Actuator assembly The control valves are normally delivered with actuators already fitted. For alternations or maintenance of actuator, the assembly should occur in accordance with the operation instructions for the actuator. 2.3 Setting into operation When the piping system is filled, the spindle sealing should be checked for leakage and, if necessary, tightened. A PTFE-V-ring unit does not require any tightening as the spring tension maintains the necessary force. The bolts must be tightened gradually in steps, diametrically in pairs, but not tighter than it is necessary for the sealing. Flange connection bolts should never be loosened or tightened when the valve is under temperature or pressure even if a leakage may arise. For actuators please see to the appropriate actuator operation instructions.

Maintenance Before any maintenance of the control valve is carried out, the piping system must be shut off and pressure free.

3.1 Exchange of the stuffing-box packing A leak stuffing-box packing should initially be carefully tightened to stop the leakage. If this does not help, a new layer should be inserted, or the complete packing should be replaced. 3.1.1 Additional packing layer Step A: Open the valve fully and unscrew the hexagon nuts (17). Step B: Lift the gland flange (7) and the spindle guiding (8) upwards. Step C: Insert adequate quantity of packing rings (split ring-displacement, splitting at 180° to avoid overlapping). Step D: Fix the hexagon nuts (17) properly. 3.1.2 Exchange Step A: Drive the actuator into middle position and dismantle the actuator. Step B: Unscrew the hexagon nuts (17) from the studs (15). Step C: Remove the gland flange (7), the spindle guiding (8) and the old stuffing box (10) and clean the packing compartment. Step D: Clean the valve spindle and check for damage and if necessary replace. If the damaged spindle is not replaced, the new packing will leak after a short period. StepE: Insert the new packing rings (split ring-displacement, splitting at 180° to avoid overlapping). Step F: Fix the hexagon nuts (17) properly.

Note: Strenuous tightening will prevent leakage, but will also have a brake effect on the spindle which aggravates the movement of the spindle.

3.2 Exchange of a PTFE-V-ring sealing unit A PTFE-V-ring unit is spring loaded and has enough set pressure to ensure a good seal even by low operation pressures. It is replaced as mentioned above. The PTFE-V-ring sealing unit should be lubricated before it is inserted. The sealing lips must face against the pressure direction. Language UK

PNEUMATIC ACTUATOR, TYPE DP

INDUSTRIES

OM5520#01.0

Pneumatic actuator, type dp 1

General The pneumatic linear actuator is designed to be mounted directly on a control valve. The pneumatic actuator converts positioning command signals into stem thrust forces. The required back setting force is produced by the spring arrangement inside the actuator. The rolling-diaphragm produces linear spindle movements over the complete stroke. The preferred mounting position is with the actuator and valve spindle in vertical position. The mode of operation for the actuator depends on how the springs are inserted when the actuator is assembled. Even when the actuator is fitted in a piping system, the mode of operation can be changed. The pneumatic actuator can be operated as: • Spring opens valve/air closes valve operation mode •

Air opens valve/spring closes valve operation mode

Table 1 1.1 Pneumatic connection The air supply should be dry and at a low service temperature. A heat-guard should be installed to prevent high service temperature. The pneumatic supply tube must be connected to the diaphragm housing (2) by operation mode "spring closes" and to the diaphragm lid (3) by operation mode "spring opens". By air failure the stem automatically returns into the original position caused by the inserted springs. Warning: The actuator diaphragm may only be pressure loaded on the side opposite of the springs. The vent hole in the other connection must remain open.

1.2 Assembly of the actuator on the valve The assembling of the actuator on the valve is shown in Figure 2. For both "spring closes" and "spring opens" operation modes the following assembling procedure should be followed: Step A: If the actuator and the valve are separated, press the plug and spindle unit (5) into the closed position for operation mode "spring closes" or into the open position for operation mode "spring opens". Warning: Make sure that the plug does not turn while pressing on the seat during assembly. Step B: Loosen the socket screws (13), remove the rotation guard (12) and the guide flange (11).

1.3 Adjustment of the starting pressure signal Step A: Drive the actuator to the required spring-starting point over the air supply. Step B: Turn the threaded bushing (14) up against the coupling flange (10) so that the collar enters into the flange and presses against it. Make sure that the plug is lying on the valve seat.

Attention: Note that sufficient thread of the valve spindle is inside the threaded bushing (14). If not, turn the coupling flange (10) downwards from the actuator spindle and pull the threaded bushing (14) against it. Step C: For operation mode: "spring closes": — Attach the guide flange (11) and the rotation guard (12) with the socket screws (13) to the coupling flange (10). — Check that the plug lifts off the seat at the required spring starting point. Step D: For operation mode: "spring opens": — Check that the plug leaves the end position at the required spring starting point, and finishes the valve stroke at the spring-range end value. — The plug must then also press on the valve seat. Step E: After the test operation set the stroke indicators (15) into the end positions. Step F: Lock the hexagon nuts (16 + 30) at the valve mid-stroke. Step G: Do not turn the plug on the seat when it is under force.

Reversal of the actuator action The actuator action can be reversed even when the valve is installed in a piping system. The position numbers mentioned in this section refer to Figure 1 and Figure 2. Step A: Drive the actuator into approximately mid-stroke position with the air supply. StepB: Loosen and remove the socket screws (13) from the coupling flange (10) and drop the rotation guard (12) over the valve spindle. Step C: Remove the hexagon nuts (31) from the actuator and lift off the valve. Step D: Reduce the air supply until the chamber is pressure free.

Manual operation device Some actuators are fitted with a manual operation device. The device is connected to the actuator by means of a new diaphragm lid, a spindle extension with a USIT-ring and a spindle sealing unit. The manual operation device is equipped with stroke indicators. The stroke indicators of both the actuator and the manual operation device must be in the same end positions when the actuator is pressure free. The manual operation device must be set into neutral position when the actuator is running automatically. The locking device of the manual operation device must be unlocked before operating. The locking device prevents an unwanted disarrangement of the setting during operation, e.g. due to vibration, etc.

Maintenance The pneumatic actuator is maintenance free. To maintain a disturbance free operation, the air should be supplied by an air-supply station. The diaphragm, spindle sealing unit and springs are wear parts and should be replaced when necessary.

4.1 Exchange of spindle sealing When the spindle sealing is changed, the slotted PTFE-guide bearing and the 0-ring should be replaced. The spindle surface must be clean and undamaged. Before the actuator is assembled, the spindle unit and the spindle must be greased.

POSITIONER, SIPART PS2 6DR5000

OM5510#05.0

INDUSTRIES

Positioner, SIPART PS2 6DR5000 1

General The following instruction is a general description of SIPART positioners and covers the complete range in the PS2 6DR5000 series. The electronic pneumatic positioner is used as the final control element of a pneumatic linear actuator or a part-turn actuator (rotary movements). The positioner converts a current output signal (4 to 20 mA) from a process controller or control system to a set point value and into a corresponding movement. The positioner changes the pressure in a pneumatic actuator chamber or cylinder until the position corresponds to the set point value. The positioner can be set up either as a single-action positioner or a double-action positioner. The single-action positioner is mainly used together with a control valve. The opposite movement for the control valve is supplied by means of springs. The double-action positioner is mainly used to control an air damper via a pneumatic cylinder (actuator). All movements of the pneumatic cylinder are supplied by the positioner. An illustration of the function diagram for the positioner is shown in Figure 1. The function diagram is shown with option modules.

1.1 Mode of operation Comparison of the set point and the actual value takes^place electronically in a micro controller. If the micro controller detects a deviation, it uses a 5-way switch procedure to control the piezoelectric valves, which in turn regulate the flow of air into the actuating chambers. When connected in a two-wire system, the SIPART PS2 draws its power exclusively from the 4 to 20 mA set point signal. The piezoelectric valve converts the command into a pneumatic positional increment. The positioner outputs a continuous signal in the area where there is a large control deviation (high-speed zone). In areas of moderate control deviation (slow-speed zone) it outputs a sequence of pulses. No positioning signals are output in the case of a small control deviation (adaptive or variable dead zone). Commissioning (initialisation) is carried out automatically to a large extend. During initialisation, the micro controller automatically determines the zero, full-scale value, direction of action, and positioning speed of the actuator. It uses these to determine the minimum pulse time and dead zone, thus optimising the control. The positioner can also be operated manually by the pushbuttons and the LCD of the SIPART PS2. The installation of the positioner must be carried out in the following order:

Step C: Push the roll (5), spring (13), and guide washer (22) onto the pin (4). Step D: Insert the pin in the lever (6) and assemble with nut (18), spring washer (14), and U-washer (12). Step E: The value of the stroke range specified on the actuator should be set or if this does not exist as a scaling value, the next greatest scaling value should be set. The centre of the pin must be in line with the scaling value. The same value can be set later under parameter "3.YWAY" in commissioning to display the way in [mm] after initialisation. Step F : Assemble the hexagon socket cap screw (17), spring washer (16), washer (12), and square nut (19) on the lever. Step G: Push the pre-mounted lever onto the positioner axis up to the stop and fix with the hexagon socket cap screw (17). Step H: Fit the mounting bracket (1) with two hexagon head screws (9), lock washer (10), and flat washer (11) on the rear of the positioner. Step I: Selection of the row of holes depends on the width of the actuator yoke. The roll (5) should engage in the pick-up bracket (2) as close as possible to the spindle but may not touch the clamping assembly. Step J: Hold the positioner with the mounting bracket on the actuator so that the pin (4) is guided within the pick-up bracket (2). Step K: Tighten the pick-up bracket. Step L: Position the mounting parts according to the type of actuator. — Actuator with ledge: hexagon head screw (8), flat washer (11), and lock washer (10). — Actuator with plane surface: four hexagon head screws (8), flat washer (11), and lock washer (10). — Actuator with columns: two U-bolts (7), four hexagon nuts (21) with flat washer (11), and lock washer (10). Step M: Secure the positioner onto the yoke using the previously positioned mounting parts.

Note: Set the height of the positioner so that the horizontal lever position is reached as close to the stroke centre as possible. The lever scale can be used as orientation. It must be guaranteed that the horizontal lever position is passed through within the stroke range.

2.2 Mechanic connection to a pneumatic cylinder The positioner is connected to a pneumatic cylinder by means of fixing bracket, lever arm with Allen screw, extension arm, and roller. The pneumatic piston is connected to a guide rail with an oblique angle via a linkage. The guide rail moves together with the piston, and the roller/lever connection senses the position of the piston. By operating both sides of the pneumatic cylinder, the set point is reached. A spring inserted between the fixing bracket and the lever arm secures that the roller is pressed down against the guide rail.

2.3 Mechanic connection to a rotary actuator Figure 3 shows the mechanic connection of the positioner to a rotary actuator. Step A: Attach the mounting console (9, actuator specific) onto the rear of the positioner and secure using the hexagon head screws (14) and lock washers (15). Step B: Adhere pointer (4.2) onto the mounting console in the centre of the centring hole. Step C: Push coupling wheel (2) onto the positioner axis, pull back by about 1 mm and tighten the hexagon socket head screw (18) with the Allen key provided. Step D: Place the carrier (3) onto the end of the actuator and secure using Fillister head screw (16) and washer (17). Step E: Carefully place the positioner with mounting console onto the actuator such that the pin of the coupling wheel engages in the driver. Step F: Align the positioner/mounting console assembly in the centre of the actuator and screw tight (screws are not included in the delivery, they are part of the actuator mounting console). Step G: Follow the start-up sequence as described later. Drive the actuator to the end position and adhere the scale (4.1) onto the coupling wheel (2) according to the direction of rotation and rotary actuator. The scale is selfadhesive.

Pneumatic connection Ensure that the air quality is suitable. Grease-free instrumental air with a solid content < 30 um and a pressure dew point 20 K below the lowest ambient temperature must be supplied. Warning: For reasons of safety, pneumatic power may only be supplied after assembly when the positioner is switched to operating level "P manual" operation with electrical signal applied. 4.1.1 Selection of P manual mode Before pneumatic power is connected, the positioner must be in P manual mode. The display must show "NOINIT" in the bottom line.

4.1.2 Pneumatic connections Figure 4 shows a view of the positioner controls and connections. Step A: If required, connect a manometer block for supply air and actuating pressure. Step B: The silencer in the exhaust output can be removed if necessary. Step C: Connect actuating pressure Yl and/or Y2 (Y2*} is only used with doubleacting actuators) according to the desired safety position. Step D: Connect the supply air (1). The pressure should be between 1.4 to 7 bar. Note: In order for spring-loaded pneumatic actuators to be able to reliably exploit the maximum possible actuating path, the supply pressure must be sufficiently greater than the maximum required final pressure of the actuator.

4.1.3 Safety position when the electric power supply fails For a single-action actuator is Yl deaerated. For a double-action actuator is Yl equal to the supply air pressure and Y2 is deaerated. 4.1.4 Restrictors To increase the positioning times for fast actuators when necessary, the airflowcan be reduced with the restrictors Yl and Y2 (only for double-action valves). Turning the restrictors in the clockwise direction reduces the air flow until it is shut off. To set the restrictors it is recommended to first close them and then open them again slowly (see initialisation process RUN 3). 4.1.5 Purging air switchover The purging, air changeover switch located above the pneumatic terminal block on the valve manifold can be accessed when the housing is open. When the switch is in position "IN" the interior of me housing is purged with very small quantities of clean and dry instrument air. In position "OUT" the purging air is led directly out of the instrument.

Commissioning Commissioning (initialisation) is carried out automatically to a large extend. During initialisation, the micro controller automatically determines the zero value, full-scale value, direction of action and positioning speed of the actuator. It uses these to determine the minimum pulse time and dead zone, hereby optimising the control. The positioner can also be operated manually by the pushbuttons and the LCD of the SIPART PS2. The commissioning of the positioner can be divided into the following steps: • Preparation for initialisation Start the automatic initialisation procedure Language UK

5.1 Preparation for initialisation Step A: Check and set the gear transmission switch to the correct position. Figure 4 (position 8) indicates the location of the switch. For linear actuators the gear transmission switch is set according to the stroke range as described in Table 1 for the parameter "3.YWAY". For part-turn actuators 90° must be selected. Step B: Check that the pneumatic supply power (inlet air) is present. The operating pressure should be at least one bar greater than is necessary for closing/opening the valve during initialisation.

Step C: Without initialisation the positioner is in "P manual mode" and "NOINIT" flashes in the display. This level can also be reached by using "55.PRST" function (see Table 1). Step D: Check the free running of the mechanics in the whole actuating range by moving the actuator with the keys "f " and "J." and driving to the respective end position. Step E: With linear actuators drive the actuator to horizontal lever position. The display must indicate 48% to 52%. If necessary, correct the value by adjusting the sliding clutch. After the check is completed, the actuator must be approximately half way along its stroke. This is due to establishment of the action direction during automatic initialisation.

5.2 Automatic initialisation Figure 6 shows the configuration mode including the operation in this mode and Table 1 shows the parameter/configuration list. Figure 7 shows the initialisation process of the positioner. The initialisation process is stored in the microprocessor. This means that an additional initialisation only is necessary if any parts of the unit have been changed. Note: The numerical values used in Figure 5, Figure 6, and Figure 7 are examples. Step A: Call the configuration mode by pressing the hand symbol key for longer than 5 seconds. Step B: Set the actuator type, linear or part-turn, in the menu item line "1 .YFCT". Step C: Switch to the second parameter by pressing the hand symbol key briefly. Step D: Set the rated angle of rotation for feedback in the menu item line "2.YAGL". It is vital that this value corresponds to the setting of the gear transmission ratio selector (Figure 4, position 8), 33° or 90°. Step E: Switch to the next parameter by pressing the hand symbol key briefly. Step F: This parameter ("3.YWAY") is only set for linear actuators and if the total stroke in mm should be displayed at the end of the initialisation phase. To do this, select the same value in the display to which the carrier pin to the scale on the lever is set to. Step G: Switch to the following parameter by pressing the hand symbol key briefly. Step H: Start the initialisation ("4.INITA") by pressing the " f key for longer than 5 seconds.

Step I: During the initialisation phase "RUNl" to "RUN5" appear one after another in the bottom of the display. Please note that the initialisation process may last up to 15 minutes depending on the actuator. Note: The ongoing initialisation can be aborted at any time by pressing the hand symbol key. The previous settings are retained. All the parameters are reset to the factory setting only after performing a preset "55.PRST". Step J: If problems occur, carry out the measures as described in the table "Possible messages" shown in Figure 7. Step K: The initialisation is completed when "FINSH" appears in the bottom of the display. Step L: When pressing the hand symbol key briefly the menu item line "4.INITA" is displayed. Step M: To exit the configuration operating mode, press the hand symbol key for longer than 5 seconds. The software version is displayed after about 5 seconds. The instrument is in manual operation after releasing the key. Step N: The positioner can be changed to automatic mode by pressing the " j " key once as indicated in Figure 5. Step O: The automatic mode is the normal mode. In this mode the positioner compares the set point current with the current position and moves the actuator until the control deviation reaches the dead zone. Operation in the configuration mode

Service and maintenance The positioner is largely maintenance-free. The positioner is fitted with filters in the pneumatic connection as protection against coarse particles of dirt. If the pneumatic energy supply contains particles of dirt, the filters may be clog and impair the function of the positioner. In this case thefilterscan be cleaned as follows: Step A: Switch off the pneumatic power supply and remove the pipes. Step B: Unscrew the cover. Step C: Remove the three screws from the pneumatic connector strip. Step D: Remove the filters and O-rings behind the connector strip. Step E: Clean the filters (e.g. with compressed air). Step F: After cleaning first insert the filters in the recesses in the housing and then place the O-rings on the filters. Step G: Align the pneumatic connector strip on the two lugs and screw tight with the three self-tapping screws. Note: Make sure that the same thread is used. To do this, turn the screws anticlockwise until they snap into the thread audibly. Only then should the screws be tightened.

General The multistage in-line centrifugal pumps are used as condensate, make-up, and feed water pumps in boiler plants. To have a proper functioning of the centrifugal pumps it is essential that the pumped liquid does not contain any steam, air, solid particles or fibres. Furthermore the liquid must not attack the pump material chemically. 1.1 Technical data •

Electrical data: see motor nameplate.

•

Ambient temperature: Max. 40°C.

•

Minimum inlet pressure: see section 2.

•

Maximum inlet pressure: see Table 1. However, the actual inlet pressure + pressure when the pump is running against a closed valve must always be lower than the "maximum permissible operating pressure".

Table 3 •

Liquid temperature: -20°C to 120°C. See also Table 2 which indicates the relationship between liquid temperature and maximum permissible operating pressure.

Note: In condensate and feed water systems where an open hot-well is used it is recommended to keep a temperature in the hot-well of 85-95°C. •

Further technical data can be found on the data sheet related to the pumps.

Calculation of minimum inlet pressure The minimum inlet pressure "H" in metres head required to avoid cavitation in the pump is calculated as follows: H = p b x 10.2 - NPSH - Hf - Hv - Hs •

pb = barometric pressure in bar (barometric pressure can be set to 1.0 bar). In closed systems pb indicates the system pressure in bar.

•

NPSH = net positive suction head in metres head (to be read from the NPSH curves in Figure 2 and Figure 3 at the highest flow the pump will be delivering).

•

Hf = friction loss in suction pipe in metres head at the highest flow.

•

Hv = vapour pressure in metres head, see Figure 1. Tm = liquid temperature

• Hs = safety margin = 0.5 metres head. If the calculated "H" is positive, the pump can operate at a suction lift of maximum "H" metres head. If the calculated "H" is negative, an inlet pressure of minimum "H" metres head is required. There must be a pressure equal to the calculated "H" during operation.

Example: Pump type = CR 20 - 60 Hz, flow rate = 24 m3/h, pb = 1.0 bar. Hf = 3.0 metres head, liquid temperature = + 90°C. Hv (from Figure 1) = 7.5 metres head. NPSH (from Figure 2) = 2.5 metres head. H = p b xl0.2-NPSH-H f -H v -H s H = 1 x 10.2 - 2.5 - 3.0 - 7.5 - 0.5 = -3.3 metres head. This means that an inlet pressure of minimum 3.3 metres head is required. Relationship between Hv and Tm Hv

Start-up Note: The pump is not allowed to run against a closed discharge valve as this will cause an increase in temperature/formation of steam in the pump which may cause damage to the pump. If there is any danger of the pump running against a closed discharge valve, a minimum liquidflowthrough the pump should be ensured by connecting a by-pass / drain to the discharge pipe. The drain can for instance be connected to a hot-well / tank. Warning: Do not start the pump until it is filled with liquid and has been primed and vented. 3.1 Priming

Note: The following does only apply to systems where the liquid level is above the pump inlet Step A: Close the discharge isolating valve and loosen the vent screw in the pump head, see Figure 4. Note: Pay attention to the direction of the vent hole and take care to ensure that the escaping water does not cause injury to persons or damage to the motor or other components. In hot water installations, special attention should be paid to the risk of injury caused by scalding hot water.

3.2 Checking direction of rotation Do not start the pump to check direction of rotation until it has been filled with liquid. Note: The direction of rotation should not be checked with the motor alone, as an adjustment of the shaft position is required when the coupling has been removed. The correct direction of rotation is shown by arrows on the pump head and/or on the motor fan cover. When seen from the fan, the pump should rotate counterclockwise. 3.3 Starting Before starting the pump: Step A: Open the isolating valve completely on the suction side of the pump and leave the discharge isolating valve almost closed. Step B: Start the pump. Step C: Vent the pump during starting by loosening the vent screw in the pump head until a steady stream of liquid runs out the vent hole, see Figure 4.

Warning: Pay attention to the direction of the vent hole and take care to ensure that the escaping water does not cause injury to persons or damage to the motor or other components. In hot water installations, special attention should be paid to the risk of injury caused by scalding hot water. When the piping system has beenfilledwith liquid: Step D: Slowly open the discharge isolating valve until it is completely open. When pumping liquids containing air, it is advisable to vent the pump regularly. To vent the pump: Step E: Loosen the vent screw in the pump head during operation. 3.4 Frequency of starts and stops Motors smaller than 4 kW should not start more than 100 times per hour. Other motors should not start more than 20 times per hour.

Maintenance Caution: Before starting work on the pump, make sure that no power is supplied to the pump and that it cannot be accidentally switched on. Before removing the cover of the electrical terminal box and before any removal/dismantling of the pump, make sure that the electricity supply has been switched off. Pump bearings and shaft seal are maintenance-free. If the pump is to be drained for a long period of inactivity then: Step A: Remove one of the coupling guards to inject a few drops of silicone oil on the shaft between the pump head and the coupling. This will prevent the shaft seal faces from sticking. When fitting the coupling guards, make sure that they are centred vertically in the recesses in the pump head. 4.2 Motor bearings Motors which are not fitted with grease nipples are maintenance-free. Motors fitted with grease nipples should be lubricated with a high-temperature lithium-based grease. In the case of seasonal operation (motor is idle for more than 6 months of the year), it is recommended to grease the motor when the pump is taken out of operation.

Frost protection Pumps which are not used during periods of frost should be drained to avoid damage. Step A: Drain the pump by loosening the vent screw in the pump head and by removing the drain plugfromthe base. Warning: Care must be taken to ensure that the escaping water does not cause injury to persons or damage to the motor or other components. In hot water installations, special attention should be paid to the risk of injury caused by scalding hot water. Do not tighten the vent screw and replace the drain plug until the pump is to be used again. Step B: Before replacing the drain plug in the base, screw the by-pass valve out against the stop, see Figure 4. Step C: Fit the drain plug by tightening the large union nut followed by the bypass valve.

I GENERALITES 1.1 -INTRODUCTION The mRoy pump is a dosing pump with incorporated hydraulic diaphragm, oil-lubricated with sealed housing, with a variable swept-volume adjustment which can be set when stopped or running. It is designed for continuous service in industrial operation. 1.2 - OPERATING PRINCIPLE - Worm (052A) / tangent wheel (052) pair drives connecting rod (214) through means eccentric of wheel (052). - Connecting rod (214) gives piston (012) a reciprocating motion with constant stroke. - Through means of oil contained in chamber (D), the piston drives diaphragm (298A) between 2 contour plates (298). - Relief valve (212A) protects the pump.

of the

held fast

Suction phase: Piston (012) draws back and sucks in the oil (H) behind diaphragm (298A). The differential pressure which is created is transmitted by flexible diaphragm (298A) enabling the pumped fluid to be drawn in with perfect separation between the pump mechanical parts and the pumped fluid. When adjusting sleeve (E) linked mechanically to piston (012) opens orifice (B) of oil bypass (C), the additional oil is supplied by housing (081). Discharge phase: Piston (012) moves forward and forces the oil back to housing (081) through by-pass (C) and orifice (B) until this orifice is blocked by adjustment sleeve (E). The oil then pushes diaphragm (298A) which moues forward proportionally to the fraction of remaining swept-volume, after blocking orifice (B). The dosed liquid is pushed back by the diaphragm through the discharge check-valves. Flowrate adjustment: The discharge flowrate is adjustable when running, from 0 to 100%, by turning adjustment knob (255) which displaces, in the oil bath, and thus without any effort, adjustable liner (012A) and thus the position of orifice (B).

II. INSTALLATION 2.1 - UNPACKING AND STORAGE The packing must be carefully examined at reception in order to ensure that the contents have not suffered any obvious damage. Open the packing carefully; one should be careful not to damage certain accessories which may be fastened to the inside of the packing. Examine the contents and check them against the delivery slip. The packing contains: - One pump. - Oil, depending on versions (see chapter 3.9) - A list of wear-and-tear parts, accompanied by section drawings and space-requirement drawings. - An instruction manual for pump installation, upkeep and maintenance Storage precautions For storage less than 6 months: Storage is to be carried out preferably in the original packing and protected from inclement weather conditions. For storage longer than 6 months: Preserve the original packing. Also provide packing under plastic heat-sealing wrapping and dehydrating bags. Store the pump in protected, covered premises with full oil charge.

2.2 - RECOMMENDATION FOR INSTALLING THE PUMP 2.2.1 Manutention Put the sling under the motor terminal box and under the motor flange. Cross the two ends of the sling and close the loop (see diagrams). Before attempting to move it, check that the entire unit is well balanced. Nota: As soon as the pump is in position, fasten it down.

2.2.2 - Installing the pump - Fasten the pump to a horizontal support using its fastening holes. Arrange enough free space around the pump so as to be able to have easy access, and to ensure the upkeep and adjustments (accessibility to the liquid end, filling, and housing oil draining). - Connect the priming drain of the liquid end to a drip-collecting tank - If the service pressure is greater than 3.5 bars, remove the spring located in the discharge check-valve box. CAUTION: Pumps installed outdoors must be protected from the elements. 2.2.3 Oil filling (Fig. 1A). - Unscrew the oil filler plug located on top of the pump. - Unscrew the level indicator located on the side of the pump. - Pour the oil in until it reaches the threading of the level indicator. - Screw the level indicator back in. - Fill up with oil to the middle of the level indicator. - Screw the oil filler plug back on.

Before operating the pump, check the direction of rotation of the motor which must be according to the arrow stamped on the motor (Counter-clockwise direction when seen from top). To reverse the direction of rotation, just reverse A and B or A and C.

CAUTION : DO NOT FORGET TO CONNECT THE PUMP TO EARTH

c=>

Electric protection of the motor (thermic protection or by means of fuses) is to correspond to the rated current indicated on the motor data plate.

2.4 - HYDRAULIC SYSTEM Pipework - Generalities As far as possible, avoid exerting stresses due to incorrect alignments between rigid pipes and the centreline of valve boxes. Provide facilities for disassembly (union-pieces, and so forth...). Clean piping before assembly. 2.4.1 Suction pipings The pump is to be located as close as possible to the suction point and the piping is to be as short and as direct as possible. If possible, have the suction point located slightly above the pump; in the event of long period of rest, the pump will not unprime. The diameter of the piping must be bigger or equal to the connection diameter of the liquid end. The suction piping is to be ABSOLUTELY AIR TIGHT (check after assembly). When it is not possible to avoid long suction pipework, use a RESERVOIR tank or a balancing column located as close as possible to the suction aperture of the pump. 2.4.2 Delivery pipework The diameter of the piping is to be bigger or equal to the connection diameter to the liquid end. Be sure that the piping and accessories fitted on the delivery line are sufficiently strong to withstand the delivery pressure.

2.6 - INSTALLATION OF ACCESSORIES Proper functioning of the pump depends on whether certain accessories available from DOSAPRO MILTON ROY are fitted or not. The salesman is at your disposal to determine the accessories which are best adapted to your plant. 2.6.1 Non return valve (F) Necessary when the pump is fitted above the suction point. Thus minimizing the risk of unpriming; it is fitted with a filter. 2.6.2 Filter It is very CAUTION when there is gravity feed; it avoids accumulation of solid particles in the valve assemblies and guarantees precision and pump life. 2.6.3 Safety valve (C) The safety valve is to be vertically installed just above the liquid end, after the damper and before any other accessory. The return line of the valve should be connected to the drainage tank or to the sump. The safety valve protects the metering pump, the piping and accessories in the event of accidental overpressure (e.g. shutting off of valve). This accessory contributes to safety for users by eliminating risks of the bursting or rupture of components under pressure. It is recommended that a safety valve should be fitted on all installations. 2.6.4 Damper (D) Compressible gas-reserve device; this dampens the flow and pressure pulsations caused naturally by the dosing pump. It is absolutely essential that the pulsation dampener be installed vertically on the discharge and/or suction piping of the dosing pump, as near as possible to the latter, before any other accessory and for it to be placed in the flow. For the volume and the pre-expansion of the dampener, see chapter 1.3. CAUTION: Dampener construction materials must be compatible with the liquid to be pumped and with the pumping pressure. 2.6.5 Non return valve (A) The non-retum valve is to be installed in line on the delivery piping. Its operation may be improved by installing a dampener located upwards on the line. 2.6.6 Injection nozzle (E) Fitted at the injection point, it acts as a non-return valve. It isolates the processed fluid from the main fluid (often water).

1 1 2.6.7 Insulation Valve (F) When the pump is not running, it is essential to insulate it from the pressure circuit with a manual or automatic valve, to prevent any return pressure in the liquid end, which could damage the pressure plate of the oilactuated diaphragm.

2.7 - INSTALLATION CALCULATIONS 2.7.1 General Sizing of the plant suction line corresponds to the NPSH calculation (Net Positive Suction Head) and it aims to avoid any risk of cavitation. Very often when processing non viscous liquids (typically less than 50 cp), the NPSH calculation is needed to verify the following condition:

d1

W with W- Liquid density. Pa = Suction pressure (bars absolute). Tv = Vapour pressure (in bars). Ha = Suction height (in m). (Ha is negative with the pump placed above the suction gravity fed). L = Length of the piping (in m). Q = Max flowrate of the pump (in l/h). N = No of pump strokes (in strVmin). d = Inside diameter of the piping (in mm).

1x144x560 (1-0.025)+ 1> 2 + 0.016 v 1 ' 12.52 thus: 10.945 > 4.064

This condition shows:

The condition is met and the pump will not give rise to cavitation.

When the NPSH condition is not obtained, the installation conditions must be improved by making or envisaging the following modifications: - Place the pump under load: Ha increases - Place the pump near the tank : L decreases - Increase the diameter of the piping: d increases (the most effective solution) - Place an pulsation dampener at the suction (see chapter 1.3) Do not hesitate to consult your usual DMR representative for complete calculations.

I I I OPERATION AND MAINTENANCE

3 . 1 - C H E C K I N G BEFOR S W I T C H I N G O N -

Check that the pump is properly mounted on its base Check the oil level. Check that the pump is set at 0% Check that all the isolating valves on the suction and discharge circuits are open. Check that the pump is properly supplied with liquid. If hot cold machine parts lead to a potential danger, check that the these parts are protected against accidental constact at site.

3.2 - STARTUP - Tun the pump ON - Place the vernier on the 50% position, for 10 minutes. - Untighten by around 1/4 turn, drain plug (B) located on the liquid end (Fig. 19) and (Fig. 20). Thus, the air trapped in the suction piping and the pump head can escape via the drain. Wait until the liquid comes up to the evacuation level of this drain. Let it flow for a few seconds in order to degas it completely, then retighten the drain plug.

3.3 - R O U T I N E CHECKS Periodically, it is necessary to check: - The level and cleanliness of the oil. - Leaks or unusual noises.

3.4 - PREVENTIVE MAINTENANCE Before any servicing operation on the pump, it is necessary to turn the motor power supply OFF.

Conductivity electrode, ERL 16 1

Description The conductivity electrode, type ERL 16 is used for monitoring the conductivity of the feed/boiler water and can be installed in the condensate system, feed water system, or directly into the boiler. The conductivity of the water produces a proportional current when the measuring surface and voltage supply remain constant. The conductivity electrode is provided with an electrode rod completely insulated by a PTFE tubing with the exception of the measuring surface. A pressure-tight sealing between the electrode rod and body is ensured by means of a Teflon tube. An illustration of the conductivity electrode is shown in Figure 1 together with an installation example. The electrode can be used in connection with a salinity monitoring system or a continuous blow down system. When used in a salinity monitoring system the electrode is connected to a conductivity limit switch type LRS l-5b or a salinity controller type LRR l-5b, which continuously monitors the conductivity of the water and give alarm if the set limit value is exceeded. When used in a continuous blow down system the electrode is connected to a salinity controller type LRR l-5b and a continuous blow down valve type BAE. The system provides fully automatic control of the blow down wastage. Automatic closing of the blow down line is ensured during boiler shut down.

INDUSTRIES

Conductivity limit switch, LRS 1-5b 1

Description The conductivity limit switch, type LRS l-5b is used to amplify and transform signals from a conductivity electrode, type ERL 16 or LRG 16-4, for continuous monitoring of the conductivity in feed and boiler water. An illustration of the front panel can be seen in Figure 1. The conductivity limit switch is provided with two LEDs. The green LED (lb) indicates a < limit value and the red LED (la) indicates a > limit value. By means of the switch (3) the measuring range can be selected between 0-10000 |o,S/cm and 0-1000 |uS/cm. The limit value is continuously adjustable on the switch point adjuster (2) within the ranges of 400-10000 uS/cm or 40-1000 uS/cm. The switching hysteresis of the limit switch is 1%. The temperature influences can be compensated on the adjuster (4) up to max 250°C. Basic adjustment applies to 25°C. Illustration of the conductivity limit switch LRS l-5b

For wiring to the electrode screened cable is required, and the length and properties of the cable stated in Table 1 must be observed. The screen should only be connected to terminal 12 of the LRS l-5b limit switch, and not at the electrode. The screen must not have contact with any metal part of the plant. Language UK

1.2 Commissioning When the conductivity limit switch is commissioned or re-calibrated carry out the following work steps: Step A: Take sample of the liquid that should be monitored via a sample cooler and determine the conductivity with a conductivity meter. Step B: Select the measuring range by means of the switch (3) provided on the front panel, see Figure 1. The possible selection ranges are 0-10000 uS/cm or 01000 u.S/cm. Step C: Turn the adjuster (4) onto scale division "7". Step D: Adjust the switch point adjuster (2) to the conductivity level found. Step E: When reaching the service temperature of the boiler, turn the adjuster (4) slowly to the left until the red LED (la) extinguishes and the green LED (lb) lights up. The temperature is thus compensated.

Note: Gases dissolved in water, such as carbon dioxide or ammonia, increase the conductivity and simulate a higher salt content (TDS) of the boiler water.

1.3 Performance test The conductivity limit switch can be tested performing the following work procedures: Step A: Short-circuit terminals 3 and earth of the electrode. The red LED (la, Figure 1) on the conductivity limit switch should light up independently of the position of the switch point adjuster (2). StepB: Short-circuit terminals 9 and 12 of the conductivity limit switch. The red LED (la) should light up independently of the position of the switch point adjuster (2). Step C: Unplug the terminal box of the electrode. The green LED (lb) should light up independently of the position of the switch point adjuster (2).

1.4 Maintenance Deposits on the electrode tip produce an error in the measurement. If the electrode is used in fluids prone to form deposits, it is recommended to clean the electrode tip every six months.

1.5 Faultfinding Performance test error If the performance test is negative check for the correct wiring of the conductivity limit switch and electrode according to the wiring diagram shown in Figure 2. Record error If the conductivity limit switch does not record the adjusted conductivity limit value then re-calibrate it. Clean the measuring surface of the conductivity electrode.

OIL DETECTION EQUIPMENT

Oil detection equipment 1

General This chapter contains installation, operation, and maintenance instructions for the ultrasonic interface detection system, type 402 SD, using control unit type MCU200. Each Mobrey ultrasonic control system requires a sensor to suit the specific application, plus a control unit. These instructions cover the control units in the MCU200 series.

Sensor installation 2.1 General description The ultrasonic sensor contains two piezoelectric crystals. A high frequency signal (3.7 MHz) generated by the control unit is transmitted to one piezoelectric crystal by coaxial cable. This crystal converts the electrical signal into an ultrasonic oscillation. The sensor design allows the ultrasonic oscillation to pass from the transmitter crystal to the receiver piezoelectric crystal. The sensors of type 402 are "gap" type sensors, where the two piezoelectric crystals are separated by a gap. When the gap is in liquid the signal reaches the receiver, because of the low ultrasonic attenuation of the liquid. When the gap is filled with air, no ultrasonic signal can pass from transmitter to receiver. See Figure 1. Working principle of the oil detection equipment

INDUSTRIES

When the gap is filled with liquid, the piezoelectric receiver crystal converts the ultrasonic wave into an electrical signal, which is transmitted back to the control unit using a second coaxial cable. Usually the two coaxial cables to the sensor are in one overall sheath. The control unit circuitry is a feedback amplifier, which oscillates when the sensor is wet, and is quiescent for the sensor dry. The "oscillating" or "non-oscillating" sensor states dictate the output relay states of the MCU200. For interface detection the sensor "oscillates" in a clear liquid, and is "nonoscillating" at the interface.

2.2 Switching levels and orientation The gap sensors should normally be mounted with the gap vertical, to avoid build up of solids on the sensor faces on either side of the gap. In this condition the switching level will be halfway up the face: if the sensor is mounted from the side of the tank this is normally on the centreline of the cylindrical body. Occasionally such sensors are mounted with the sensor faces horizontal, either to avoid air bubbles passing through the gap or for convenience of installation. In this case the switching level will be at the sensor face at the top of the gap.

2.3 Installation of sensor The sensor must be handled with care - it is a measuring instrument. Before installation, check that sensor, cable and control unit have not been damaged in transit. Drill and tap a hole with a suitable thread. It is advisable to use a boss or similar on thin walls. The sensor has a tapered thread. Use Ptfe tape or similar to seal the thread. Mark the sensor hexagon to identify the gap orientation of the sensor, if appropriate. Take care not to damage the sensor cable during tightening. The cable should be laid on cable trays and separated from any high voltage or mains cables. The normal cable termination is a plastic gland (to fit the MCU200 control box drilled hole) and crimped terminal pins to suit the MCU200 terminals.

2.4 Extensions cables Extension cables up to 50 metres long can be fitted to most Mobrey ultrasonic sensors in the factory to special order but a better site arrangement is to have a separate extension cable. Table 1 shows a list of suitable extension cables.

Suitable extension cables SO m RG174 RG178

50 -100 m URM76 RG58

Above 100 m Consult Aalborg Industries

Table 1 When double coaxial cable needs to be extended, two sets of coaxial plugs and sockets will be needed, one set for transmit and one receive. Care must be taken that the connectors are not connected to earth or shorted together in any way, to prevent cross-talk or pick-up. The coaxial connections must be made in a waterproof junction box. Terminal blocks should not be used.

INDUSTRIES

The extension cable needs to be of 50 Ohm characteristic impedance. Suitable dual coaxial extension cables can be purchased from Aalborg Industries. For extensions over 50 metres it is recommended two runs of single coaxial low loss cable is used, with the transmit and return cable runs separated by 0.15 metres to minimise crosstalk. If several sensor cables are being run together then all the transmit cables (those connected to E2) should be grouped together and all receive cables (those connected to IE) grouped together maintaining the separation specified above. Two cables are required per sensor. The RG178 should be used where the cable itself is subject to temperatures exceeding 74°C.

Control unit installation 3.1 Mechanical The control unit is supplied with three holes drilled in the bottom (longer) side of the box. Two glands are supplied for the power input cable and relay output cable. The sensor is normally supplied fitted with a suitable gland on the cable. Two further holes can be drilled in the bottom side of the box should these be needed: it is recommended that the circuit board is removed whilst drilling extra gland holes. Figure 2 shows the dimensions of the MCU200 housing box. MCU200 Housing dimensions

This provides an earth contact for the pcb mounting pints. 3.2.3 The relay The relay output connections are labelled: •

NC - Normally closed (relay de-energised)

The screens of these coax cables are connected to the terminals marked "E".

3.2.5 The auxiliary input The auxiliary input is a terminal which can be connected to a "push to reset" button to achieve a latching alarm, or to another Mobrey Control unit, to give a pump control from the MCU200 unit relay output. If a short circuit is connected between terminals 3 & 4, the MCU200 relay, once de-energised, is held de-energised. Even if the sensor attached to the MCU200 changes state, to that which should energise the output relay, this relay will not energise until the link between terminals 3 & 4 is broken in the circuit external to the MCU200.

3.3 Switch settings in MCU200 series 3.3.1 Gain switch and potentiometer See section 4. 3.3.2 Frequency selection This slide switch is labelled "FREQ" and is located between the sensor terminal block E2, and the Aux. input terminals. This selects the operating frequency of the MCU200 oscillator, which for the present installation must be set to 3.7 MHz (switch in the "up" position). The setting required is dictated by the sensor type connected to the control unit. 3.3.3 Cable check option selection This slide switch is located directly above the sensor terminal block E2. It is labelled "Cable Check" and the ex factory setting is "OUT" with the slide switch to the right. By sliding this switch to the left, the cable check circuitry is brought into action. This circuitry monitors the continuity of the screens of the two coaxial cables attached to the sensors: normally these are linked at the sensor to the metal body of the fitting (or to each other in the case of non metallic sensors). If this continuity is broken, the "FAULT" LED" will illuminate giving an indication that the sensor cable is damaged, and the MCU200 will give the "ALARM" output relay state (see Figure 4). 3.3.4 Relay output and LED logic selection The bank of six slide switches towards the top of the pcb sets the relay output state logic relative to the sensor state, associated time delays and the LEDs. These are slide switches, best adjusted with a pencil, and the ex factory wetting is with all switches to the right. Each switch is colour coded as shown in Figure 4, and the PC board labels give brief function information.

Note: At Figure 4 OSC means sensor oscillating. £ means relay energised, NE means de-energised. Set the switches in the following order, starting at the bottom and working upwards: BLUE: If the MCU200 relay is to be energised (E) when the sensor is oscillating (OSC) then set the No 6 blue switch to the right (OSC=E). This is the preferred setting, to give a de-energised relay in the ALARM state for a gap sensor as a low level alarm. GREEN: This selects the relay change which is subject to the time delay selected on the top switches. When the No.5 green switch is set to the right, the delay occurs between the sensor changing state and the relay de-energising or becoming "not energised" (NE). This time delay is a minimum of 0.15 seconds, (achieved by switching the top BROWN switch to the right) and is used to prevent relay chatter at the changeover point. Longer time delays are selected on the top three slide switches as shown in Figure 5. The relay change in the opposite direction is immediate (within 50 milliseconds).

YELLOW: Only one of the GREEN or RED LEDs will be illuminated at any one time. These LEDs show the state of the MCU200 output relay. The RED LED is labelled "ALARM" and the GREEN LED is labelled "NORMAL". The yellow slide switch (Number 4) determines which LED will be illuminated when the relay is energised (E). It is usual to have the GREEN/NORMAL condition occur with the relay energised, i.e. with switch Number 4 to the right (E=GREEN).

Applications 4.1 Gain adjustment Correct adjustment of the gain (HI/LO switch and potentiometer) is essential for proper operation of any ultrasonic sensor system. This adjusts the gain of the feedback amplifier in the control unit, which produces oscillation of the sensor when the coupling between the ultrasonic crystals is sufficient. Therefore the higher the gain setting, the lower the coupling needed to produce an oscillating sensor. The universal control unit of the MCU200 operates with many sensors, so the correct setting for the particular sensor and application should be found on site by experiment, if possible. This will take account of particular site conditions like RF coupling between extension cables, which can affect the maximum allowed gain. Other liquid characteristics, such as presence of suspended solids, or air bubbles, can mean that for reliable operation the MCU200 gain must be set as high as possible, to overcome future solids build up, but at least one potentiometer division below the maximum allowed level, to ensure temperature and component ageing stability. The particular procedures outlined below for gain adjustments give the mid point gain settings, which may need to be adjusted to meet specific site/sensor future requirements as indicated above.

4.2 Interface detection 4.2.1 Interface detection between two dissimilar liquids Viscous liquids, emulsions and liquids containing solid particles have a greater ultrasonic attenuation than clear liquids. This technique is used to detect which liquid is present at the sensor, for example for the separation of oil and water. For this duty Mobrey 402 sensors are used, operating at 3.7 MHz to produce the maximum ultrasonic difference between two liquids monitored. The gain is adjusted so that the sensor oscillates only in the liquid with the lower ultrasonic attenuation: this is usually the clearer liquid (water in the example of Figure 6). Note that the signal when oil is present in the sensor gap will be the same as that for air in the gasp, and that emulsion layers give a very high attenuation.

Step A: Reduce the gain potentiometer with the sensor immersed in one of the liquids until a "false dry" indication is obtained. Note the position of the pot. Step B: Repeat for the sensor immersed in the other liquid. Step C: Set the potentiometer half way between these two values. Correct performance requires a total difference between the two set points of at least 3 divisions.

Interface detection between two immiscible similar liquids When liquids are ultrasonically very similar - as happens for example with paraffin or oil and water - the procedure in section 4.2.1. produces very little difference between the two "false dry" points. In this case the "reflection" method of interface detection is used. An illustration of this method is shown in Figure 7. Note: The Mobrey 402 sensor in the hot well tank is installed as shown in Figure 7. If an ultrasonic beam is transmitted from one liquid to another at a suitable angle (10%) it is split at the interface into a reflected and a refracted beam, so that it does not reach the receiver crystal. If there is no interference in the gap, but only one liquid, the beam is received and the sensor oscillates. Interface detector by reflection method Paraffin

The gain adjustment is made so that the gain is 3 divisions higher than the highest false dry position obtained, as in section 4.2.1. Performance at the interface should then be checked. Note: That the non oscillating state of the sensor, at the interface, also occurs throughout any emulsion layer at the interface, and also when the sensor is in air.

5.2 Fault finding Step A: At least one LED should be illuminated. If not check the power supply to the unit. Step B: If the "Fault" LED is on, check the coax cable to the sensor for incorrect wiring or damage. Particularly check continuity of extension cables, connection of crimped connectors on cable ends. The pcb board can be checked by linking the two terminals labelled E on the sensor terminals this should cancel the fault indication LED. Step C: If the sensor is giving incorrect indications check the gain adjustment (see section 4.0"). Check for correct sensor operation whenever the gain is adjusted away from the normal set point. Assume an overlap of 2 divisions between the "LO" and "HI" gain ranges. Step D: Check that the incorrect operation has not been produced by incorrect setting of the frequency selection switch, or an external short circuit on the Auxiliary input terminals. Step E: The circuit board can be checked by linking the sensor terminals 1 and 2 with a wire, to simulate an oscillating sensor.

Type: • Wafer check valve, type WCV 6100 Application: • For steam and liquid media Design: • The wafer check valve is designed to be sandwiched between welding neck flanges or slip-on flanges, with horizontal flow or vertical flow upwards. The disc is eccentrically placed in relation to the body to obtain a self-centring effect at installation Size: • Nominal diameter: DN 200 Connection requirements: • Min. inline diameter of connection pipe/flange: 206.5 mm • Length of required min. inline diameter: 160 mm Material: • Body: carbon steel • Waferdisc:AISI316L • Disc seating: metallic Technical data: • Operating pressure max: 25 bar • Max. cold hydraulic test pressure: 37.5 bar


Language UK

• Opening pressure at horizontal flow (60° open): 19 mbar • Opening pressure at vertical flow upwards: 22 mbar • Standard Kv value: 1205 m3/h • Operating temperature max.: 250°C • Operating temperature min.: -10°C • Weight: 7.5 kg Installation: • The check valve can be installed sandwiched between welding neck flanges or slip-on flanges • Determine the correct installation situation and the direction of flow. It must be installed either in a horizontal flow or where the flow is vertically upwards • The valve is self-centring. However, it must always be ensured that it is completely centred in relation to the connection pipe/flange. Use the body rim (external) diameter for this purpose • The check valve can be installed directly on a valve, but a distance of 2-3 times the pipe diameter is preferable. • In case of a steam system with vertical installed check valve a steam trap should be installed for drainage of condensate

Type: • Pressure switch • KPS45 Application: • The units are pressure-controlled switches. The pressure controls are suitable for use in alarm and regulation system. Enclosure: • IP 67 to IEC 529 and DIN 40050. • The pressure control housing is enamelled pressure die cast aluminium (GD-AISi 12). The cover is fastened by four screws which are anchored to prevent loss. The enclosure can be sealed with fuse wire. Adjustment: " • When the pressure control cover is removed, and the locking screw (5) is loosened, the range can be set with the spindle (1) while at the same time the scale (2) is being read. In units having an adjustable differential, the: spindle (3) must be used to make the adjustment. The differential obtained can be read direct on the scales (4). • To ensure that the plant functions properly, a suitable differential pressure is necessary. Too small a differential will give rise to short running periods with a risk of hunting. Too high a differential will result in large pressure oscillations.

Material: • Sample cooler: austenitic stainless steel grade316L • Cooling water inlet valve: stainless steel • Sample inlet valve: stainless steel. • Compression fitting: carbon steel

Type: • Sample cooler Size: • SCS 20 Application: • The sample cooler is designed for taking manual samples of boiler water for analysis. The cooling water is turned on and the sample inlet valve is adjusted until a sample of boiler water is obtained at a suitable temperature. For manual sampling it is not normally necessary to measure sample or cooling water flow rates.

Technical data: • Coil design pressure: 32 bar g • Coil design temperature: 300°C • Body design pressure: 10 barg • Body design temperature: 100°C

Installation: • Fit the SCS 20 so that the bottom of the unit is accessible for the collection of the cooled sample. • Connect the cooling water inlet in !4" nominal bore pipe via an inlet valve. • The cooling water outlet should be piped to an open drain or tundish. • The sample inlet pipe should be in 6 mm O/D tubes. • The sample inlet to the cooler can be taken direct from a boiler or steam line isolating valve. Operation: • Sample pipe work will become very hot under normal working conditions, and will cause burns if touched. • Open the cooling water inlet valve first and ensure that a flow can be seen at the cooling water outlet. • It is essential that cooling water is flowing before opening the sample inlet valve. • Gradually open the samples inlet valve and regulate the flow to achieve a cooled sample at about 25°C.

• Allow the sample to run for a while before collection. This will ensure that a true sample is collected for analysis. • When enough liquid has been collected close the sample inlet valve first and then the cooling water inlet valve. • After closing the sample inlet valve the sample out connection may drip for a few minutes while the coil drains. Performance: • When it is required to predict the performance of the sample cooler system, the table below gives the sample outlet temperature to be expected for two boiler pressures an for two cooling water flow rates. Example • A sample flow rate of 30 1/h is required from a boiler operating at 10 barg. For a cooling water flow rate of 0.4 1/s, from the table the sample outlet temperature would be 4K (4°C) above the cooling water inlet temperature. If the cooling water is 15°C, the sample temperatures would be 19°C.

INDUSTRIES

Steam atomising burner 1

General The steam atomising burner is capable of burning both diesel oil and heavy fuel oil. As the burner is a very vital component of the boiler plant, the operating staff should be thoroughly instructed with regard to the operation of the equipment and the safety regulations. This is due to the fact that burner problems are often caused by incorrect burner operation. With frequently occurring burner faults, the nearest service centre should be consulted. To ensure a safe and reliable function of the burner it must be inspected at least once a year, in addition to the normal maintenance intervals. The inspection should be carried out by a representative of the supplier or by another competent and qualified person. It should be clearly understood that for a plant of this complexity it is not practicable to anticipate all the possible circumstances which may arise during the operation life of the plant. Therefore, should circumstances arise in plant operation and maintenance which are not specifically covered by these instructions, the matter should be referred to Aalborg Industries for consideration and advice. Repairs, adjustments, alterations or changes to plant operations not covered by these instructions should not be effected without reference in writing to Aalborg Industries. Information in this manual is subject to changes without notice and does not represent a commitment on the part of Aalborg Industries. It is not allowed to copy this manual or part hereof for any purpose other than the purchaser's personal use. Aalborg Industries shall not be held responsible for any damage or losses caused by the use of this manual.

1.1 Safety regulations

Caution: To ensure a safe burner operation, the burner has to be installed and commissioned by qualified personnel, and all guidelines in these instructions have to be followed. All safety equipment such as flame sensor equipment and correcting elements may only be replaced by qualified personnel. Warning: Repair of any of the safety components is NOT permitted. Failure to comply may result in serious injury or death and may cause considerable damages to the boiler plant.

OM5580#02.1

INDUSTRIES

Steam atomising burner, type KBSA 1

Precautions with fuel oil Fuel oil is usually the residue of crude oil after the removal by distillation of the most volatile oils and gases. Fuel oil in its liquid state is very difficult to ignite in bulk and not capable of spontaneous combustion. The vapour, however, is explosive when mixed with air, and being heavier than air, tends to accumulate in low levels, such as bilges and bottoms of tanks where it may remain undiscovered until ignited. It is always present in a partly filled oil tank, or in a tank which has contained fuel oil and from which the vapour has not been removed by artificial means, and is given off through the vents from tanks in process of being filled. A leak in any part of the oil burning system, if allowed to continue, may result in an accumulation of this explosive vapour. Ignition of the vapour has been caused by an open light, electric spark, smoking, spark caused by striking metal, heat from the filament of a broken electric lamp, sparks from funnel, or has been communicated from galley or fires under boilers. Warning: An oil fire cannot be extinguished by water but may be extinguished by sand, steam or chemical fire extinguishers. An intelligent appreciation of the properties of fuel oil, as described above, is a better preventative of accident than adherence to any set of rules that may be prescribed. The following precautions, however, should be rigidly enforced: • When oil is being received no naked light, or electrical apparatus liable to spark should be permitted within 20 m of the oil hose, tank, or compartment containing the tank, or the vent from the tank, excepting when special arrangements are carried out. •

While receiving fuel oil the storage tank must be closely watched for leaks and care must be taken that all outlets from tank, except the vents, are closed. No naked lights or electrical apparatus, liable to spark should be permitted at any time in a compartment containing a fuel oil tank. Electric lamps used in such compartments should have a wire protector around the bulb, or be of a type that will ensure the breaking of a circuit through the lamp in the event of the lamp being broken.

•

No one should be allowed to enter a fuel oil tank until it has been gas freed, and any person then entering the tank must have a life line around his body properly tended in order that he may be hauled out if overcome by gas. Electrical fuses and switches, unless of the enclosed type, should not be permitted in compartments containing fuel oil pumps or piping. Care must be taken that the wire-gauze protectors in vent pipes from fuel oil tanks are at all times intact.

•

Dampers fitted in the uptakes of the boilers, must be kept fully open while burning oil. Otherwise gas may accumulate dangerously in the furnace with a resultant blowing out into the boiler or engine room.

•

The valves on glass gauges on fuel oil storage or settling tank should be kept habitually shut. When a reading of the gauge is desired the valves may be opened, but must at once be closed again.

•

In each boiler or engine room fitted for oil burning there should be fire extinguishing apparatus in accordance with the requirements/rules of the authorities and classification societies in question. The fire extinguishing apparatus can for example be a fire hose, permanently coupled and of sufficient length to reach all parts of the boiler or engine room and either:

— a box containing at least 85 litres of dry sand with a large scoop, or — chemical fire extinguisher of the tank type. •

When the fuel oil system has not been in use for a longer period or after joints in the piping have been re-made, the system should be tested "cold", under a pressure at least equal to the working pressure, before fires are lighted. During the test a careful inspection for leaks should be carried out.

•

Fuel oil should not be habitually heated above 65°C for light oils and 120°C for heavy oils and never above the flash point of the oil in any part of the system. Care must be taken to prevent accumulation of oil or vapour in any place outside the system, and in ships, particularly in bilges under the furnace. This can be accomplished by rigid cleanliness.

•

In the event of a considerable accumulation of oil in the furnace, such as may be caused by a sudden extinguishing of the burners, the vapour must be blown out through the boiler into uptake and funnel by fan or steam hose before the fires are again lighted.

Note: This furnace purge is done automatically when the burner is operating in "auto-mode", but has to be done manually when the burner is in "manual-mode".

General system description The following contains a general description of the components in the burner unit. The burner unit consists of a steam atomising burner and supply systems for oil, steam, and combustion air with the required data for correct burner performance. The burner is mounted on the top or the side of the boiler, and the combustion air fan must be connected to the burner via an air duct. The burner is capable of burning both diesel oil and heavy fuel oil. An illustration of the KBSA burner is shown in Figure 1.

2.1 Burner design The steam atomising burner gives the thermal input to the oil-fired boiler in order to achieve the specified steam demand in the operating range. The burner is designed so that the flame fits the actual furnace dimensions and gives a correct combustion provided the supply conditions of fuel, air and steam are correct. The burner consists of a wind box and an air register with divided swirler. The guide vanes of the inner swirler have a fixed design whereas the guide vanes of the outer annular swirler have a design depending on the furnace geometry. 2.1.1 Wind box design The steel wind box is the main structural part of the burner unit and is provided for mounting or welding onto the boiler. On the burner wind box the front plate is mounted in which for lance, ignition burner, flame scanner and peep-hole are incorporated. The valve arrangement for fuel oil and atomising steam is mounted directly on wind box, flexible hoses connect the valve arrangement to the lance. 2.1.2 Burner register The burner register is the duct between the wind-box and the furnace. The ignition burner, the burner lance with the atomiser, and the flame stabiliser are placed in the burner register. For maintenance and inspection purposes the burner lance can be dismounted from the front plate, making cleaning and replacement of the atomiser very easy.

The flame stabiliser is designed to create an internal re-circulation of hot gases to provide continuous ignition, and hereby to stabilise the flame which results in less pulsation. 2.1.3 Burner lance The burner lance, illustrated in Figure 2, contains the Y-jet atomiser, where steam and fuel are mixed and ejected. This oil mist is then mixed with primary and secondary combustion air, and the combustion is completed. Ignition is achieved by a flame from the ignition burner. Both lance and ignition burner are purged during normal stop to prevent drip and build-up of carbon deposits. Burner lance

2.1.4 Y-jet Atomiser The Y-jet atomiser, illustrated in Figure 3, operates on the principle of the atomising medium [B] (steam or compressed air) and fuel oil [A] at high velocity, impacting within the intersecting atomising medium and oil passage of the nozzle. To achieve this, passages are in an Y-configuration and disposed radial around the nozzle, and the dimension and number of passages are dependent on the oil burner capacity. This has the advantage of maintaining the high passage velocity right up to the point of impact. Further atomisation takes place in the combined mixing and ejection of the atomiser. Y-jet atomiser

Atomisation is almost independent of oil pressure and consequently the excellent quality is maintained down to the minimum firing rate. The atomising medium and oil are supplied from the shut-down valves through flexible hoses to the burner lance. In addition to the very low consumption of the atomising fluid (approx.1% of the oil weight at full load), the Y-jet burner has a high turndown ratio, up to 10:1, dependent on size. 2.1.5 Flame failure equipment Flame failure during light up and normal operation is detected by a photo electric cell mounted on the burner unit and coupled to an amplifier mounted inside the control panel. On loss of flame this flame failure equipment will automatically shut down the burner. The number of photo cells for automatic service and manual service depends on the classification society.

2.2 Atomising steam/air system Steam for atomising is supplied from the boiler drum or common steam line, and the steam pressure is reduced to 6 bar or lower. The steam pressure at the burner is automatically lowered for stabilisation of flame when the burner load is decreased. When the burner is stopped normally, the purge valve will open automatically and the oil remaining in the burner lance will be atomised and fired into the furnace and the burner lance is cleaned. The atomising steam valve is closed after the end of the -purge period.If steam is not available, compressed air at a pressure of approximately 7 bar can be used as atomising medium for starting up. 2.2.1 Atomising steam pressure control The steam pressure is controlled by an electrically operated regulating valve, and the corresponding controller keeps a pre-set pressure according to the fuel flow to the burner. 2.2.2 Atomising steam pipe - drain A thermostatic steam trap can be fitted to drain the condensate in order to have dry steam at the burner.

2.3 Ignition oil system The diesel oil is supplied by a pump which is only running during ignition. In plants which consist of two boilers each burner has its own ignition oil pump, and a solenoid valve between these two pumps which is normally closed. 2.3.1 Ignition oil pump The ignition oil pump is a gear pump fitted with a pressure limiting valve and a filter inside the housing. The pump pressure should be adjusted to give 8-10 barg at the ignition burner. If a pump fails, in a double boiler plant, the other can be selected to supply diesel oil for ignition to both burners, and in this mode the solenoid valve must be open.

2.3.2 Ignition burner The ignition burner, illustrated in Figure 4, operates on the principle of mechanical pressure jet atomisation. The ignition burner is retractable and inserted/retracted by an air cylinder. Combustion air for the ignition burner is supplied from the compressed air system, and can be adjusted by means of the throttle valve, placed after the solenoid valve. The ignition burner is automatically purged by compressed air. At the end of the furnace purge period the solenoid valves for diesel oil and combustion air to the ignition burner are released and the ignition burner is ignited by means of an electric high-tension spark. The ignition burner is simultaneously moved into ignition position. When the ignition flame is stable the pick-up of this release the oil for the main burner. The ignition burner must ignite the main burner within the pre-set ignition period. At the end of the ignition period the solenoid valves to the ignition burner are switched off and closed, the ignition burner is purged with compressed air and returns to starting point in the retracted position.

2.4 Combustion air system The combustion air system supplies air to the burner according to the demands of the control system. The draft loss of the burner air register is measured by a differential pressure transmitter, which converts the signal to a flow signal used by the control system for automatic air/oil ratio control. The combustion air is supplied by a directly driven centrifugal fan. The fan is mounted on a common bed frame with motor, inlet vanes, and servo-drive unit. The air flow to the burner is regulated by inlet vanes mounted on the fan suction side. The inlet vanes are of a multi-blade design and regulated by a servo-driven unit comprising an air cylinder and an I/P positioner. A silencer can be mounted on the fan suction side.

2.5 Oil supply system This section describes the oil system in general terms together with some of the requirements needed to have a safe and reliable burner operation. The burner and the oil system are designed for both diesel oil and heavy fuel oil operation. A diagram of the oil system for steam atomising burners is shown in Figure 5. The diagram shown is for a plant with two steam atomising burners. Please note that the oil system can be designed somewhat differently from plant to plant depending on the requirements.

The oil system consists of oil tanks for diesel oil and heavy fuel oil, mixing tube, oil pumps, heaters, ignition oil pumps, and equipment for oil pressure and temperature control. The automatic shut-off valves, re-circulation valve, solenoid valves, and the rest of the necessary burner mountings are all fixed on the wind-box. All shut-off valves are ball valves, and the automatic valves are with electric/pneumatic actuators. The arrangement of the components on the burner is made as simple as possible and is hence very user friendly regarding operation and maintenance. To avoid blockage, all pipelines carrying heavy fuel oil must be traced either by means of steam or electrically. The oil flow control valve is fitted with a pneumatic converter/positioner. To obtain a very accurate regulation of the oil, which is very important to have a large turndown ratio, the valve is also fitted with an adjustable Cv-adjuster. This Cv-adjuster makes it possible to adjust the pressure loss coefficient of the valve whereby the oil flow regulation can be optimised to each single installation. The oil flow is measured by a screw-type flow meter. The fuel oil temperature before the burner inlet is kept precisely at the desired value by means of an electric actuated control valve, a single loop PID-controller, and a PtlOO temperature transmitter. The fuel oil pressure control loop includes an electric actuated control valve to ensure the correct pressure at the fuel oil inlet of the burner, and thereby providing a larger turn-down ratio of the control valve. A single loop PID-controller and a standard 4-20 mA pressure transmitter ensure optimum and accurate functionality.

2.6 Mode of operation The air/oil ratio is controlled automatically. The oil flow is measured by a screwtype flow meter and the air flow is measured as a differential pressure across the burner air register. The modulation of the burner is fully automatic on each fuel type. The operator can change to manual operation. The change from diesel oil to heavy fuel oil and the change from air atomising to steam atomising and vice versa are achieved by manual operation.

Functional description This section contains a functional description of the burner plant and the flow ways in the system.

3.1 Fuel oil supply system To give a clear picture of the fuel oil supply system the system is split into two separate systems, a part ("Part one") containing the accessories connected to the fuel oil tanks, pumps and heaters, and a part ("Part two") containing accessories related to the burner and regulating system. The two subsystems of the fuel oil system are described in the following two subsections and they are illustrated schematic in Figure 5 and Figure 6 respectively.

3.2 Fuel oil supply system, "Part one" "Part one" of the fuel oil supply system is characterised as the part of the system which is connected to the fuel oil tanks and heater. The primary system is schematic illustrated in Figure 5. The oil system is shown as a plant with two boilers, but is also valid for a plant with only one boiler. Schematic illustration of fuel oil supply system, "Part one"

3.2.1 Oil tanks The heavy fuel oil tank may be provided with a heating coil for heating up the fuel oil in the tank to at least 50°C, at which temperature it will be possible to pump the oil. The oil temperature in the tank should not heated too much in order to keep the oil temperature controlled by the heater units. Whenever a boiler plant is intended to operate on heavy fuel oil, all pipes carrying fuel oil must be insulated and traced in order not to cool the oil if the circulation is stopped. The tracing can be done either by means of steam heating or by means of electric heating cables.

Language UK

OM5580#02.1

3.2.2 Fuel selection The fuel type is selected by manually operating the three-way valve (Gl 15) in the oil system. The heavy fuel oil can be taken from both the service tank and settling tank. If the heavy fuel oil is taken from the settling tank the suction level from the tank must be arranged in a sufficient level height to prevent e.g. water, sand, or particles from entering the oil system. 3.2.3 Return flow from the burner When the burner is in stand-by mode, a minimum of fuel oil is returned via the oil return line to the three-way valve ( G i l l ) . From here the fuel oil is either led to the pump suction side via the mixing tube (Gl 10) for degassing or to the heavy fuel oil settling tank. The three-way valve normally returns the fuel oil to the mixing tube. The three-way valve is a pneumatically operated actuator controlled by a solenoid valve (Gl 13). The solenoid valve has a manual operator screw-type slot for emergency operation. If the fuel is changed from diesel oil to heavy fuel oil by means of the three-way valve (Gl 15), the three-way valve ( G i l l ) automatically changes position and returns the oil to the heavy fuel oil settling tank for a period of time. This arrangement is necessary to avoid that diesel oil is heated by the pre-heater in this specific operating sequence. The viscosity of the re-circulated diesel oil will decrease and hereby also the lubrication characteristic. If the oil is led to the pumps this will cause damage to the pumps. After the pre-set time period has expired, the three-way valve ( G i l l ) returns to normal position, and the fuel flows to the mixing tube (Gl 10). The time period must be set with regard to oil pressure and the quantity of oil in the pipe system. 3.2.4 Fuel oil supply pump The oil system is fitted with one set of supply oil pumps suitable for both diesel oil and heavy fuel oil (G05 and G12). The supply oil pumps (Gl47) is a twin type package in which two screw spindle pumps with driving motors are connected by a cross over arrangement to the valve housing. Each pump is fitted with a pressure relief valve, a filter (G02 and G09), a mano/vacuum gauge (G04 and Gl 1) at the filter, and stop valves (G07 and G14). The pumping capacities for each of the pumps are calculated in such a way that there will be sufficient oil flow to the burner(s) and the pressure regulating valve in full load condition. The control system receives a signal from the pressure transmitter (G99). If the pressure drops below the pre-adjusted set point, the operating pump stops, and the stand-by pump starts. If the pressure continues to drop, the control system gives alarm for low oil pressure and stops the burner(s). 3.2.5 Fuel oil pressure control A part of the fuel oil returns to the pump suction side through the oil pressure control valve (Gl00) which keeps a pre-set pressure in the fuel oil system. The fuel oil pressure control loop includes an electric control valve (Gl00) to ensure the correct pressure at the fuel oil inlet of the burner. This provides larger turn-down ratio of the control valve. A single loop PID-controller and a standard 4-20 mA pressure transmitter (G99) ensure optimum and accurate functionality.

3.2.6 Pre-heater The oil system is provided with pre-heater(s) (G22) heating the heavy fuel oil to the correct temperature/viscosity by means of steam. The fuel oil is changed by means of the manually operated three-way valve (Gl 15). When diesel oil is selected, the stop valve (G51) must be opened, and the stop valve(s) (G25) must be closed. When heavy fuel oil is selected, the stop valve(s) (G25) must be opened, and the stop valve (G51) must be closed. 3.2.7 Fuel oil temperature control The heavy fuel oil temperature after the pre-heater(s) is kept at the desired value by means of a flow control valve (G20), a single loop PID-controller, and a PtlOO temperature transmitter (G28). 3.2.8 Ignition oil system The ignition system always operates on diesel oil no matter if the steam atomising burner operates on diesel oil or heavy fuel oil. This secures a reliable ignition. The diesel oil is supplied by an ignition oil pump (G72) with filter (G70). The pump is only operated in ignition mode. The ignition oil pump is a gear pump fitted with a pressure limiting valve and a filter inside the housing. The pump should be set to 810 bar. A plant with two boilers is provided with two ignition oil pumps. If a pump fails, the other can be selected to supply diesel oil for the ignition to both burners.

3.3 Fuel oil supply system, "Part two" "Part two" of the fuel oil supply system is the part of the system which is situated next to or on the burners. The secondary system is schematic illustrated for a single burner in Figure 6.

From the fuel oil heater or by-pass line the fuel flows to the stop valve (5), fuel flow transmitter (6), stop valve (7), stop valve (8), fuel oil flow control valve (9), and stop valve (10). The by-pass valves (3 and 4) is arranged for the fuel flow transmitter and the fuel oil flow control valve. At the burner the fuel is either re-circulated directly back to the mixing tube (if the burner is stopped) or into the burner (if the burner is in operation) through the threeway valve (19). If the burner is in operation, the fuel flows through the shut-off valve (17) and stop valve (14) and finally enters the burner lance. If the burner is stopped, the fuel will flow through the three-way valve (19) to the throttle valve (1), which directs the flow back to the diesel oil tank or the heavy fuel oil tank.

3.4 Atomising steam system The atomising steam system is illustrated schematic in Figure 7, and is described in the following. Steam is supplied from the boiler drum valve or the common steam line, and flows through the stop valve (1), the pressure regulating valve (2), the non-return valve (3), and the stop valve (4). At the burner the steam enters the condensate separator (12), and flows through the shut-off valve (23), and the stop valve (16), and finally enters the burner lance.

The purge valve (13) is opened automatically, when the burner is stopped normally, in order to clean the burner lance for oil. The condensate from the condensate separator (12), flows through the stop valve (7), the steam trap (8), the stop valve (9), and the non-return valve (10). The by-pass valve (11), is arranged for the steam trap. When steam is not available (for example at start-up), compressed air can be used by opening the stop valve (6) and then air flows through the non-return valve (5), the shut-off valve (23), and the stop valve (16), and finally enters the burner lance.

The combustion air is taken directly from the engine room through the silencer (20), if provided, reducing the noise level from the suction side to approximately 95 dB(A). The inlet vanes (22), regulates the air flow to the fan. The inlet vanes are regulated by an air cylinder (21), which is controlled by an I/P positioner (41). The I/P positioner receives a 4-20 mA signal from the combustion control system. The inlet vanes closed positions are proven by a limit switch (42). The control air pressure for the I/P positioner is controlled by the air filter regulator (40). From the fan discharge side the combustion air flows through the air duct to the burner wind box.

3.5.1 Air Register The combustion air enters the wind box through the inlet flange and then the burner air register after passing a perforated plate to give an even air distribution. Passing through and leaving the burner air register tube, the air passes the primary air swirler, giving air mixture with oil/steam mist and flame stabilisation, and the secondary air swirler respectively, giving air for combustion zone. Both swirlers give the air a rotation and the correct distribution of air flow between primary air and secondary air. The burner air register draft loss is measured by a differential pressure transmitter (DPT25). The signal is converted to a combustion air flow signal in the control system.

Commissioning The following commissioning instructions are valid for steam atomising burners type KBSA with Y-atomisers and with a standard delivery of individual parts for the burner unit and supply systems from AALBORG INDUSTRIES. Prior to the commissioning, the instructions for the individual parts of the burner unit and supply systems should be studied. The special instructions for the boiler and the control system should also be consulted. The instructions should only be considered as a guideline. This is due to the fact that each plant should be commissioned individually to obtain the best burner performance for the specific plant. During the commissioning of the burner unit and supply systems, it might be necessary to adjust some regulation parameters or timer settings in the control system to optimise the function of the plant. These adjustments are not described in the following sections, but should be carried out as the optimisation requirements emerge. Please see the instructions for the control system.

5.1 Commissioning start When the system is started at commissioning, the following procedure must be followed: 5.1.1 Boiler Step A: Check that the boiler is ready for operation according to the special instructions for the boiler Step B: Increase or decrease the water level in the boiler to approximately 50 mm below normal water level.

Table 1 Whenflushingthe oil system, the minimum and maximum oil flow through the fuel oil regulating valve (9) can be checked and adjusted. Step Y: After completing theflushing,the internal spring loaded by-pass valves of the fuel oil pumps must be adjusted to a pressure of approximately 3 bar above the set point of the oil pressure control valve (Gl00) (this may be readjusted after the final commissioning). The set point of the fuel oil pumps must be below the set point (30 bar) of the safety valves, on the fuel oil heater. Step Z: Clean the fuel oil pump filters. 5.1.4 Burners - diesel oil mode On delivery from Aalborg Industries, the burner unit has been pre-adjusted to fit the task. Even though the burner unit has been pre-adjusted, it is advisable to carry out additional checks during commissioning. These checks should be carried out with Language UK

regard to adjustment of the atomiser and flame stabiliser distance, ignition electrodes, etc. This means that it is necessary to pull out the burner lance, flame stabiliser, and ignition burner. Before the burner unit is assembled, check and note the commissioning measurements. The obtained measurements should be inserted in the "measurement and settings scheme". Step A: Check that the burner gun and nozzle are clean. Step B: The nozzle tip should be adjusted to approximately 40 mm in front of swirler. Step C: If no atomising steam is available, the burner can be started with compressed air 3-6 barg for atomising. From 3 barg in low load up to approximately 30% load and then the air pressure should be increased gradually up to 6 barg at approximately 60% load and kept constant at higher loads. Step D: When atomising steam is available, the controller for atomising steam must be checked and adjusted to 3-6 bar depending on the burner load. Step E: Close the stop valves (14, Figure 6) and check burner start/stop sequence.

Attention: Before and during start-up, the furnace must be checked with regular intervals for oil spillage. If an oil spillage is present in the furnace, the cause must be determined and the failure must be rectified. The furnace should be purged until it is free of oil. Step F: To facilitate the commissioning, switch to "Burner - manual operation" on the control panel and follow the instruction.

Note: During commissioned, the boiler pressure and temperature must not be intensified too rapidly as this might cause stresses in the boiler. The burner should be kept in minimum firing position during the first commissioning period. Step G: Check and adjust the diesel oil/air ratio. The combustion air flow signal and the fuel oil flow signal must be set in the controller on the control panel to obtain an O2 content of approximately 3-4% and a soot number of 1-3 Bachrach at loads above 30%. At lower loads the O2 content is higher. When the controller is set up, there is a function key on the control panel marked "Air/fuel ratio" where the normal adjusting of air/oil ratio can be carried out. This could be necessary if the bunker type is changed. In the same controller the max./min. oil flow and the ignition oil flow are set. Oil flow for ignition will be found during commissioning, typically 15% of full load. Step H: Check/adjust all interlocks and alarms for burner.

Step I: Check the burner in automatic mode by switching the detachable key switch to "Automatic operation". Step J: Check the master-slave function, for plants intended to operate in this mode (see the instructions regarding the control system). 5.1.5 Oil system - heavy fuel oil mode When the burner has been commissioned on diesel oil and when steam is available for heating, the commissioning on heavy fuel oil can be carried out. Caution: Heating of diesel oil in the piping system must be avoided. The change of fuel from diesel oil to heavy fuel oil is achieved by manually operating the three-way valve (Gl 15). When heavy fuel oil is selected, the threeway valve ( G i l l ) automatically changes position and returns the oil to the heavy fuel oil settling tank for a period of time. This arrangement is necessary to avoid heating of the re-circulated diesel oil when the burner is in stop mode. The viscosity of the re-circulated diesel oil decreases and with it also the lubrication characteristic. This will cause damage to the oil pumps. After the pre-set time period has expired, the three-way valve ( G i l l ) returns to normal position. The time period must be set with regard to minimum oil flow and the quantity of oil in the system. To operate the oil system in heavy fuel oil mode the procedure mentioned below must be followed (the stated item numbers refer to Figure 5): Step A: Check that the burner is stopped. Step B: Check that oil is present in the heavy fuel oil tank. Check that the stop valve which connects the heavy fuel oil tank to the oil system is open. To avoid cavitation of the oil pumps, the viscosity of the oil in the heavy fuel oil tank should not exceed 400 cSt. If necessary, the oil tank should be heated. Step C: Check and adjust the switchover time for the three-way valve (Gill). Step D: Select heavy fuel oil on the manually operated three-way valve (Gl 15). Step E: Check that the three-way valve (Gl 11) changes position. It should also be checked that the valve is changed back to normal position when the time period has expired. Step F: Select one of the pre-heaters for operation. The other pre-heater should be in stand-by mode. Step G: Open the stop valves for the operational pre-heater and check that the stop valves are closed for the stand-by pre-heater. Step H: Close the stop valve (G51). Step I: Close the drain valves for the pre-heaters. Step J: Open the stop valves before and after the steam trap for the pre-heaters. Language UK

Step K: Open the stop valves placed just before and after the temperature regulating valve (G20). Step L: Close the by-pass valve placed at the temperature regulating valve (G20). Step M: Open the stop valve, placed in the steam pipe just before the pre-heater, for the operational pre-heater and close the stop valve for the stand-by preheater. Step N: Adjust the temperature set point for the temperature regulating valve (G20) in the control system. The viscosity of the oil at the atomiser should be between 15-20 cSt. The pre-heating temperature can be determined by means of the "viscosity-temperature chart" found in this manual. Step O: Check that the steam regulating valve (G20) for the pre-heaters is operational and that the temperature is raised to the desired set point. Adjust if necessary. Step P: Check that the tracing systems for the oil system and the burner unit are operational. Step Q: Bleed air from fuel oil heaters by opening air valve on heater until fuel oil is observed at air bleed outlet pipe. Step R: Check the alarm set points for too low oil temperature, low warning, high warning, and too high oil temperature. Adjust if necessary. 5.1.6 Burners - heavy fuel oil mode When the burner is commissioned on heavy fuel oil, final adjustments of the combustion process should be carried out to achieve high quality performance data. The aim is to operate the burner with lowest possible O2 content and highest possible CO2 content without the risk of an uncompleted combustion (black smoke). At the same time the reliability of the burner must be ensured. A number of initiative actions can be performed to improve and optimise the combustion process such as adjusting the air/fuel ratio, the steam atomising pressure, etc. Adjustments of the air/fuel ratio and the steam atomising pressure are made by settings in the control system. The air/fuel ratio should be checked and adjusted through the entire burner load range to ensure a correct combustion. The air/fuel ratio can be checked by measurements of the soot spot No. and the 0 2 content and/or the C0 2 content in the flue gas. The visual appearance of the flame should also be checked. If the amount of combustion air to the burner for a given oil flow is too low, the combustion will be uncompleted, and it produces black smoke. Although the 0 2 content is low and the CO2 content is high, the air flow should be increased. If, on the other hand, the O2 content is high and the C0 2 content is low, it indicates that the air flow for the combustion process must be decreased. It is not only the air/fuel ratio which is an important factor for the combustion process, but also the pressure of the atomising steam. The steam atomising pressure should be adjusted and optimised to suit the combustion process through the complete burner range. The pressure can be checked by measurements of the soot spot No. and visible control of the flame. If the steam

INDUSTRIES

atomising pressure is too low at a given burner load, the flame has a tendency to sparkle and the soot spot No. increases. Furthermore, the flame becomes unstable at low loads due to poor atomisation of the oil. If the steam atomising pressure is too high, the combustion zone is cooled and the flame becomes unstable at low loads. The following commissioning steps imply that the lighting-up procedure of the boiler is completed and that a sufficient load demand is present to carry out adjustments at 100% load. Step A: Check that the correction factor of the air/fuel ratio is in neutral position on the control panel. The correction factor is used to adjust the air/fuel ratio if the calorific value of the oil is changed, e.g. when the bunker type is changed. Step B: Start the burner and check that it ignites when the oil valves open and remains ignited when the ignition burner is shut-off. Adjust the ignition oil flow, the air/fuel ratio, or the steam atomising pressure if necessary. Step C: Start the burner several times to ensure a reliable ignition of the burner. Step D: Set the oil flow regulation valve into manual mode after start-up and adjust the oil flow to minimum. Step E: Check that the flame is stable and carry out measurements of the soot spot No. and O2 content and/or CO2 content. Adjust the minimum oil flow, the air/fuel ratio, or the steam atomising pressure if necessary. Step F: Carry out the same measurements through the burner load range in steps of 10%. Adjust the air/fuel ratio and/or the steam atomising pressure if necessary. Step G: The measurements obtained for the combustion process through the complete range together with a number of comparable combustion data should be noted and inserted in the "measurements and settings" scheme. Step H: When the burner is in operation, increase or decrease the load until the oil pressure at the atomiser and the steam atomising pressure are identical. Step I: Set this load as the steam purge position load in the control system. Step J: Stop the burner and check it during steam purging. The burner must not produce black smoke or blow out the flame before the combustion is completed. Adjust the steam purge position load if necessary.

5.2 Normal stop In modulation free mode, the control system attempts to maintain the steam pressure at the desired set point by regulation of the burner load. The burner can be regulated through the complete load range from minimum firing load to full load. However, should the steam demand decrease below the minimum firing load of the burner, the steam pressure will increase to the set point for burner stop. The burner stops and remains stopped until the set point for burner operation is reached again.

5.3 Prolonged stop When the boiler plant is stopped for a long period of time, the oil system including the pre-heaters should be flushed with diesel oil before the plant is shut-down. Furthermore, the tracing must be switched off.

Manual operation In the rare event of a total break down of the control system, the burner unit with belonging systems can be operated in manual operation (also called emergency operation). Due to the fact that the majority of the safety interlock trips and alarms are overruled in emergency mode, the safety precautions for the plant must be observed very carefully. Please note that in emergency operation mode the safety interlocks are reduced to: Too low water level Flame failure Warning: When the burner operates in emergency mode, it is very important that the boiler plant is carefully and continuously supervised by the ship engineering personnel. Pay special attention to the steam pressure and water level. The emergency equipment comprises the following components: •

Key switch for emergency operation

•

Control and signalling components

•

Additional flame detector

•

Push buttons for ignition and operating of the electric/pneumatic oil and steam valves Both "manual" and "automatic" flame scanners must be clean and placed in position at burner front to monitor the flame. When changing to manual operation, the following operations are necessary. Step A: Turn the key-operated switch on control panel to "Manual operation". Step B: Start the combustion air fan manually on the control panel. Step C: Switch the load controller to "Manual". Step D: Purge the furnace by increasing the combustion air flow to maximum and keep flow in maximum position for approximately 60 seconds. Step E: Open the steam atomising valve (16, Figure 7). Step F: Reduce the air flow to ignition load, approx. 15% load.

Step G: Push the ignition button on the local burner panel. When the ignition flame has been established, push the button for oil valve. Step H: When the lamp (flame on) flashes up, release the ignition button. Step I: The burner can now be operated from the control panel increasing/decreasing the oil and air amount on the load controller.

Step J: Check the flame monitoring equipment by pulling out the "manual" flame scanner from its mounting flange and by covering the cell window by hand. The fuel oil supply must then be cut off automatically.

Note: Only flame failure and too low water level cut the burner off automatically in this mode.

Maintenance instructions To ensure a safe and reliable function of the burner, inspection must take place with frequent intervals as described below. The inspection should be carried out by competent and properly trained personnel familiar with the operating and maintenance procedures relevant for this type of plant.

7.1 Safety regulations for maintenance work Always ensure that the electrical power is off and that nobody can start the boiler unit before commencing maintenance work. All pipes, drums, etc. must be depressurised before any maintenance work is carried out on these.

7.2 Continuous maintenance •

Control panels and other electrical equipment should be kept clean and dry. Check that no foreign matter accumulates in or around them.

•

Replace lamps, contactors, and other components when they cease to function or show signs of deterioration. A part, replaced before it actually fails, could save a costly delay.

7.3 Periodical maintenance The following check list should be followed every two weeks. Dependent on the operation conditions, however, some items may need more frequent attention. For maintenance work procedures, we refer to the separate instructions concerning each item. 7.3.1 Periodical maintenance - burner and fuel oil supply system •

OM5580#02.1

•

Check that the fan inlet is kept clean of unintended obstructions.

•

Check pipe work for leaks, particularly on flanges, joints, and connections. Repair any leaks which may cause safety risks.

•

Check the general condition of pipe work, lagging, and tracing.

•

Check that the glands of manual valves are tight enough to prevent easy operation of the valve.

•

Oil filters should be inspected and cleaned.

•

Manually operated valves should be periodically operated, if possible, to ensure free movement.

•

Check the pneumatic shut-off valves, placed just before the burner lance, for leaks.

•

Check and clean the flame scanner.

7.3.2 Burner air register and swirler If the burner plant is to perform according to the specification, it is important that the burner register is kept clean and in good condition. Inspection should be carried out at regular intervals. Large quantities of dust-laden air will pass through the register, and inevitably this tends to build up deposits. These deposits should be brushed off. The primary and secondary swirlers as well as all other surfaces exposed to radiation heat should be checked for being free of carbon or heat erosion. The refractory should be inspected for general condition and examined for being free of carbon deposit, cracks, and heat erosion. 7.3.3 Atomiser Before any examination can be made, the atomiser must be cleaned. This is normally done by soaking in a paraffin or carbon remover to wash any oil films. This also has the purpose of loosening carbon deposits. It may also be necessary to use a soft metal scraper to lift away any heavy carbon deposits. A hardened scraper should not be used as it could possibly damage the atomiser. The cleaned atomiser should then be examined for damage, and the nozzle holes checked for wear. The O-ring must be replaced every time the atomiser is disassembled. Before fitting the cap nut, the thread should be covered with an un-hardening high temperature compound. 7.3.4 Ignition burner The ignition burner is one of the most exposed items and needs a frequent maintenance. • The electrodes should be cleaned and the insulation material checked for any damage. Be careful not to damage the ceramic insulation pieces.

•

The nozzle should be checked and cleaned.

•

If the spray pattern hits the other parts of the ignition burner despite it is cleaned, the nozzle should be changed.

The trouble shooting list is based on a proper set-up of the burner plant during commissioning and/or service and that no further adjustments of the air/fuel ratio, etc. have taken place. Please note that the trouble shooting list is general for steam atomising burners and has not been made for any particular plant, but is based on several years of experience. Therefore, the cause for your specific problem may not be mentioned and vice versa. You are always welcome, however, to contact our service department for advice or service assistance. Check availability of power and fuel supplies before commencing detailed checks. Ensure that burner plant wiring diagrams relevant to the particular installation are available. When the cause of a lockout should be located, it can be of assistance to know the start/stop cycle or at which point of operation the lockout occurred, e.g. modulating. The trouble shooting list can be seen in Table 2.

Steam atomising burner settings Each plant has its individual service conditions depending on the actual design and layout of the burner and the boiler plant. Exact values for the burner cannot be given, but have to be determined at the commissioning or by later adjustments. The following tables show the standard measurements and settings for a plant which includes a KBSA burner. This enables the user to obtain some of the most important measurements and settings related to the burner for later reference. It is recommended that the user completes the scheme shortly after the commissioning when normal service conditions have been established.

PHOTO CELL

OM8630#01.0

INDUSTRIES

Photo cell 1

Description The RAR7 detector is used for supervision of yellow burning oil flames. If the photo cell detects a missing flame, the burner stops instantaneously. It is not possible to start the burner before the control system has been reset. With this type of detector, the radiation of the oil flame in the visible band of the light spectrum is used to generate a flame signal. The light-sensitive element is a selenium photo cell. When illuminated, it generates DC voltage which causes a current to flow to the input of the flame signal amplifier in the control unit. Hence, the selenium photo cell is an active detector. The cell is insensitive to infrared radiation. If the burner is started with an illuminated combustion chamber, e.g. due to glowing firebrick, the start sequence of the burner commences, but an alarm for flame failure will be indicated. The number of photo cells for automatic operation and emergency operation depend on the classification society.

1.1 Commissioning The intensity of the light radiation can be checked by measuring the detector current by means of a DC ammeter (internal resistance 5000 W). Figure 1 shows the measuring circuit. The photo cell is adjusted by changing the position in proportion to the oil flame in order to obtain the maximum detector current. Note: If the wiring of the photo cell is connected incorrectly, it is not possible to start the oil burner.

Viscosity - temperature chart 1

Description The preheating temperature can be determined by means of the viscosity temperature chart shown in Figure 1. In order to use the chart, the viscosity of the fuel oil must be known at a reference temperature. It should be noted that the preheating temperature should be set somewhat higher than the temperature shown in the chart due to the heat loss between pre-heater and nozzle/cup.

1.1 Example The example is based on a pressure jet burner. Known: Oil viscosity: 380 cSt. at 50°C Required: Preheating temperature in °C Procedure to be followed: Step A: Follow the reference temperature line at 50°C vertically down to the intersection with the 380 cSt. viscosity line. Step B: From this point move parallel down with the nearest fuel grade line. Step C: When the line meets the recommended nozzle viscosity line, go vertically up to the temperature axis. Step D: At this point read the desired preheating temperature of 150°C.

General The burner load is controlled by the control system, which receives a continuous signal from a steam pressure transmitter. This signal is compared with different set points, feed back signals, and parameters in the control system. The output from the control system is used to control the oil flow regulation valve, which is pneumatically operated by an I/P converter. To obtain a very accurate regulation of the oil flow, which is very important to have a large turn-down ratio, the valve is fitted with an adjustable Cy-adjuster. This Cyadjuster makes it possible to adjust the pressure loss coefficient of the valve whereby the oil flow regulation can be optimised to each single installation. The position numbers referred to in the following sections appear from the illustrations shown in Figure 1, Figure 2, Figure 3, Figure 4, Figure 5, and Figure 6.

Cv-adjustment 2.1 Mid band setting During calculation of the valve sizing, a trim set should be chosen so that the mean estimated Cv will be at the mid band setting. This is called the risk-free setting since it provides the means to either increase or decrease the available Cv if the actual conditions change. Figure 1 shows an example of the possible settings for a trim set. A mean Cv of 0.07 for a trim No. 5 allows subsequent adjustment to Cv 0.10, if the flow coefficient is increased, or to Cv 0.04 in the opposite case.

2.2 Adjustment setting at maximum Cv The adjustment knob should be set towards maximum Cv making it possible to scale downwards, if desired. This should be done if valve sizing calculations and actual service conditions indicate that the full rated Cv of the valve will initially be required but may subsequently lessen

2.3 Adjustment setting at minimum Cv The adjustment knob should be set towards minimum Cv making it possible to scale upwards, if desired. This should be done if valve sizing calculations and actual service conditions indicate that initial conditions require a relatively low Cv but will then increase to a higher maximum

Commissioning In the following the work procedures for commissioning of the oil flow regulation valve are described: Step A: Check that the output signal range from the I/P converter corresponds to the input signal range on the oil flow regulation valve. The pressures appear from the identification plates. Step B: Loosen the cover screws (109). Back off the hand wheel lock (121) and turn the hand wheel anti-clockwise until the cover floats free. Remove the cover (110). Step C: Check and adjust the valve characteristic (C v ). To adjust the C v , loosen and move the adjustment knob (24) along the scale (25) fixed to the top of lever No. 1 (21). The adjustment scale (25) shows the available C v values for the specified valve, and Table 2 shows the C v setting for each burner size. When the knob (24) is at the required position, tighten the knob.

Step F: Set the oil flow regulation valve into manual mode on the control system. Step G: Set the regulation output for the oil flow to 0% (4 mA) on the control system. StepH: Adjust the pressure indicated on the instrument gauge (143) to the low input signal range by means of the zero adjustment screw on the I/P converter. The instrument gauge (143) is the left pressure gauge on the oil flow regulation valve. The input signal range appears from the identification plate. Step I: Set the regulation output for the oil flow to 100% (20 mA) on the control system. Step J: Adjust the pressure indicated on the output gauge (142) to the high input signal range by means of the span adjustment screw on the I/P converter. The output gauge (142) is the right pressure gauge on the oil flow regulation valve. The input signal range appears from the identification plate. Step K: Set the oil flow regulation valve into automatic mode on the control system. Step L: Start one of the oil pumps. Set the stand-by oil flow to 0% on control system. Step M: Adjust the turn take-up screw (116) of the oil flow regulation valve until the piston (131) just begins to move. The control system must indicate 0% oil flow. Tighten with the lock nut (117). Step N: Set the stand-by oil flow back to the original set point.

Note: If the C v setting is changed after the above-mentioned work procedures have been carried out, a new zero adjustment might be required to recalibrate the closing point.

Manual operation 5.1 Hand wheel The oil flow regulation valve can be manually operated in case of a failure on the control system by means of the hand wheel. The hand wheel is located on top of the cover and fitted with a locking lever. Direct access to it does not require removal of parts. It basically consists of a threaded rod fitted with a hand wheel (120) and a lever arm stop (122). The threaded rod freely rests on the actuator bracket (108) and is guided through the cover (110) by means of the hand wheel bushing (119). The stop (122)

consists of a block screwed on the threaded rod guided in translation by the actuator bracket (108). Clockwise rotation of the hand wheel (120) moves the stop (122) up along the threaded rod and drives up the lever No. 2 (22) compressing the spring (134). This action provides for the opening of the valve if it is an open-on-air actuator and also the closing of the valve if it is a close-on-air actuator. The return to automatic operation (neutral position) is accomplished by turning the hand wheel anti-clockwise until the stop (122) contacts the bracket (108). Note: During this operation the compression releases when the stop (122) no longer contacts the lever (22). Then, continue this operation until a slight tension reappears and tighten the hand wheel lock (121).

Calibration The oil flow control valve is factory calibrated. If, for some reason, the calibration has been disturbed (e.g. due to repair, change of parts, etc.), it is necessary to carry out some adjustments. In the following the work procedures for adjustments are described: 6.1.1 Adjustment of the piston rod clevis (104b) Note: This adjustment should not be changed unless the piston (131) has been disassembled. Then, it should be made during assembly before coupling the levers to the clevises. Step A: With the piston against the diaphragm cover (137), turn the clevis (104b) in such a manner that the distance between the actuator bracket top (108) and the indicator bottom (126) is between 0.5 mm and 1 mm. The use of a shim will facilitate the operation. Step B: Couple lever No. 2 to the clevis. Admit sufficient air pressure to disengage the nut (125) and tighten it against the indicator. Take care that the indicator (126) is correctly positioned. Release the air pressure. 6.1.2 Plug stem adjustment With levers No. 1 and 2 coupled, proceed as follows: Step A: Admit sufficient air pressure to the actuator to extend the piston rod and place a shim under the indicator (126). Use a 1.5 mm shim for air-to-open actuators or a 25 mm shim for air-to-close actuators. Release the air pressure after placing the shim.

Note: At this closing point without seating force, the slides of levers No. 1 and 2 must be strictly parallel. This characteristic permits to change the adjustment knob position to obtain the truly required C v . Step B: Loosen the adjustment knob (24) and slide over the lever No. 1 to the position of maximum C v on the C v adjustment plate (25). Tighten the knob (24). Step C: Loosen the lock nut (103) by using a screwdriver applied to the plug stem end, and turn it until the plug slightly touches the seat ring. If the valve was removed from the pipe, a bubble leakage test performed on a calibration bench will permit a very accurate adjustment. By using the screwdriver, keep the plug stem in position and tighten the lock nut (103) against the clevis (104a). Step D: Admit air pressure again to disengage the shim, and release the air pressure again. Note: On air-to-open actuators, the shim thickness can be changed plus or minus 0.1 - 0.2 mm so that the levers No. 1 and 2 are in parallel position. This is done to obtain the required tightness at closing.

6.1.3 Positioner start-up pressure adjustment Step A: Pipe air supply and instrument signal lines to the positioner. Set the supply pressure in relation to the valve Cy. See Table 3. Step B: Set the signal to minimum value if it is an air-to-open actuator, or set the maximum value if it is an air-to-close actuator. Turn take-up screw (116) until the piston rod just begins to move. Tighten the lock nut (117).

Maintenance Warning: Maintenance and/or disassembly should be performed with the valve, actuator, and positioner free from all pressures.

7.1 Actuator diaphragm replacement Step A: Unscrew the two pressure connection nuts (138a) and pull the tubing (140) out. Remove the four cap screws (139), the diaphragm cover (137), and the diaphragm (136). Step B: Form a new diaphragm and insert it over the piston (131). Place the diaphragm roll into the bracket groove. Take the necessary steps not to twist or bend the diaphragm during its replacement. Step C: Replace the diaphragm cover (137) with the four screws (139) and reconnect the pressure connection nuts (138a). Check the tightness of the connections.

7.2 Adding packing Step A: To add a ring of packing, dépressurise the valve, and back off the packing flange nuts (8b) all the way. Step B: Lift the packing flange and follower and insert one ring of packing. Tighten the nuts (8b) finger tight plus one full turn.

7.3 Disassembly In some cases, it may be necessary to disassemble the valve, e.g. to replace the plug and seat ring assembly or to change packing in case of a C v max. < 0.6. Note: In the case of a C v max. > 0.6 a quick way to replace the packing prevents full disassembly of the valve (see the section "Packing quick change method"). Step A: Loosen the cover screw (109). Back off the hand wheel lock (121) and turn the hand wheel anti-clockwise until the cover floats free. Remove the cover (110). Step B: Adjust the signal for closing of the valve. Slightly change the signal so that the plug barely moves off the seat ring. Turn the adjustment knob (24) to minimum C v position.

Step C: Loosen lock nut (103) and turn anti-clockwise through 1 3/4 turns by using a screwdriver applied at the plug stem end. Shut off the signal and pressure supplies. Slightly retighten the lock nut (103) against the clevis. Step D: Loosen the lock nut (117) and fully unscrew the take-up screw (116). Remove the spring clamp (115) from lever No. 2 and force the balance spring (114) from the positioner. Step E: Remove the retainer clips (112b) from the two pivot pins (184) and pull them out from lever No. 1 and clevis (104a).

Note: This operation will be facilitated by relieving the load on the plug clevis exerted by the conical compression spring (106). While driving out the pins, using a screwdriver, push on the plug stem end. Step F: Remove the two retainer clips (112c) from pivot pin No. 4 (124) and disengage it to the uncouple piston clevis (104b) from lever No. 2 (22). Step G : Remove the two retainer clips (112a) from pivot pin No. 1 (105) and disengage it to the uncouple lever No. 1 from the actuator bracket (108). Disengage the adjustment pin smooth end (23) from the lever line No. 2 and remove the adjustment knob (24) and adjustment pin (23) from lever No. 1. Step H: Drive out the pivot pin No. 3(18) and remove lever No. 2 (22). Step I: Hold the plug stem in place by using a screwdriver put to its end and unlock the nut (103). Unscrew the clevis (104a) and lock nut (103). Remove the spring button (102), spring (106), and grommet plate (101). Step J: Remove the two packing flange nuts (8b), packing flange (10), and packing follower (9). Remove the two bracket securing nuts (8a) as well as the bracket (108). Step K: By using a packing hook, remove the largest number of packing rings (6) from the packing box. Remove the safety pin (11) and pull the plug stem to remove the packing spacer (5), plug and stem, together with the rest of the packing rings. Step L: By using a 9/16" or 14 mm piece of hex stock and a wrench, unlock and pull out the seat ring retainer (4). Step M: Pull out the seat ring (3) and then the gasket (2) by using a hook made from steel wire (diameter approximately 3 mm). Carefully fettle the hook end.

Note: The seat ring with a C v max. < 0.10 consists of two parts; The seat ring proper (3e) and a spacer (3f). The small size of the orifice of these parts does not allow for their removal by means of a hook. Therefore, it is necessary for this operation to remove the body from the pipe and turn it over and, if needed, to hit the bottom by means of a wooden mallet. Should the seat ring be jammed in its housing, it is possible to move it using a screwdriver inserted through the outlet orifice. Valves with C v max. 3.8 do not feature any seat ring gasket (2).

7.4 Assembly Before assembly, clean thoroughly the inside of the valve body and parts. Gasket seating surfaces and surfaces in contact with others must be thoroughly cleaned. On assembly, a new seat ring gasket (2) and a new packing (6) must be used. Step A: Place a new seat ring gasket (2) in the valve body (13) and install the seat ring (3) taking care to correctly centre the gasket on the seat ring shoulder. Orient it in such a manner that one of its ports lines up with the body outlet orifice.

Note: In the event of a maximum C v smaller than 0.10, the seat ring (3e) must first be positioned on the new gasket (2) taking the same precautions as shown above. Secondly, engage the spacer (3f) and orient one of its ports towards the body outlet orifice. Valves with C v max. 3.8 do not feature any seat ring gasket (2). Carefully apply grease (Never Seez or equivalent) on the threads and bottom of the retainer (4). With a 9/16" or 14 mm piece of hex stock and a wrench, torque the retainer to 8 Nm if equipped with a graphite gasket st. reinforced, or to 5.5 Nm if equipped with a glass filled P:T:F:E: gasket. Note: In case of a valve with maximum Cc 3.8, torque the retainer to 2 Nm. Step B: Engage the plug and stem assembly in the seat ring. In the case of a maximum Cv < 0.10, ensure that there is no hard point during the stocking of the plug. In case of a hard point, loosen the retainer (4) and replace the seat ring (3e) in the correct position until the stem smoothly slides. Align the hole in the spacer (5) with the safety pin (11) hole in the valve body.

Note: In the event of a maximum Cv smaller than 0.10 ensure that the retaining ring (182) is placed on the plug before engaging it in the spacer (3f). If the retainer ring is damaged, replace it. Step C: Wrap the safety pin (11) with two turns of P:T:F:E: tape (Teflon). Screw it into the bonnet five and a half to six turns from where the thread Language UK

engagement starts. To find the start of the thread engagement screw on the safety pin about one turn and pull the safety pin outwards while unscrewing it. Step D: Install packing, positioning the skive cut of each packing ring 120° away from the cut of an adjacent ring. Slightly push down the rings one after another by using a tube Vz" sch. Size 160. Install the packing follower (9) on the plug stem. Step E: Install the actuator bracket (108) and secure it with the two nuts (8a). Install the packing flange nuts (10) on the plug stem. Hand tighten the two packing flange nuts (8b) adding one full turn with a wrench. Step F: In the following sequence, place the grommet plate (101), spring (106), and its spring button (102). Screw the nut (103) and clevis (104a) on the plug stem. Adjust the nut and clevis without locking them together until the clevis holes are about 1.5 mm above the alignment of the pin holes in the actuator bracket (108).

Note: Measuring this distance can be made easier by engaging the pins (105, 184, and 18) in their respective hole. Step G: Pin lever No. 2 (22) to the bracket (108) by using the pin (18). Ensure that the hole of lever No. 2 destined for spring clamp (115) is located on the top and aligned with the force balance spring (114). Step H: Place the adjustment pin (23) in the slide of lever No. 1 and screw the knob (24) on its threaded end. Engage the pin smooth end (23) into the slide of lever No. 2 and mount lever No. 1 on the bracket (108). Couple lever No. 1 to the bracket (108) by using the pin (105) and the two retainer clips (112a).

Note: Ensure that the clevis (104a) is correctly positioned before placing lever No. 1 on the actuator bracket (108). Step I: Set the adjustment knob (24) on minimum C v position. Step J: If the piston rod clevis (104b) has not been disturbed during disassembly, couple it to the end of lever No. 2 by using the pin (124) and the two retainer clips (112c).

Note: This operation will be facilitated by placing the piston rod in an intermediate position by admitting air to the diaphragm and by setting the knob in a position where the end of lever No. 2 is left most accessible. If the clevis (104b) has been disturbed, proceed with adjustment and coupling as described in the section "Calibration".

Step K: Couple the clevis (104a) to lever No. 1. To perform this operation push to align the holes in the clevis and lever No. 1 by means of a screwdriver on the plug stem end. Couple by means of the two pins (184) and retainer clips (112b).

Note: Insert the clips on the pins between the slides of the clevis and lever No. 1. Step L: With the take-up screw (116) fully unscrewed from the spring clamp (115), place the latter in position after hooking the force balanced spring (114) first on the positioner spring bracket (151) and secondly on the spring clamp (115).

Note: The spring clamp (115) has two holes. If it is a close-on-air failure actuator the spring must be hooked in the upper hole. In case of valve open-on-air failure, the spring must be hooked in the lower hole. Step M: Admit supply and signal pressures and complete the calibration. Replace the cover (110) and turn the hand wheel clockwise to engage it in the lever arm stop (122). Tighten the cover screws (109). Step N: If the valve has been removed from the line, reinstall it according to the section "Installation" and then set the valve back into service.

7.5 Packing quick change method The fastest and simplest way to replace the packing is to remove the entire actuator without disturbing the actuator parts or calibration. However, this is not recommended for valves with a small Cy (Cy < 0.6) due to the very fineness of their plug. Vent the valve pressure and proceed as follows: Step A: Be sure that the plug is off the seat ring. With an air-to-open valve, admit air pressure under the diaphragm or turn the hand wheel to move the plug off its seat ring. StepB: Remove the safety pin (11) from the body. The safety pin engages the packing spacer (5). The function of the safety pin and spacer is to prevent the plug from being pushed out if the actuator is removed while the valve is still pressurised. The valve internal parts cannot be removed unless the safety pin is removed first. Remove the two packing flange nuts (8b) and back off the two mounting nuts (8a) as far as possible. Step C: With a block of wood and a mallet, tap the actuator plug assembly off the valve. Clean the packing box and plug stem and carefully place the new rings of packing around the stem. Position the skive cut of each packing ring 120° from that of the adjacent ring.

Step D: Assemble the actuator/plug assembly to the valve taking care to align the hole in the spacer (5) with the safety pin hole and to replace the two mounting nuts (8a) during assembly. Take extra care in guiding each ring into the packing box. Step E: Wrap the safety pin (11) with two turns of P.T.F.E. tape (Teflon). Screw it into the bonnet five and a half to six turns from where the thread engagement starts. To find the start of the thread engagement screw the safety pin about one turn and pull the safety pin outwards while unscrewing it. Step F: Replace the packing follower, packing flange, and flange nuts (8b). Tighten the nuts finger tight plus one full turn. With an air-to-open actuator, vent the air pressure or turn the hand wheel to move the plug back in contact with the seat ring. Set the valve back into service.

7.6 Positioner maintenance

Note: Shut off supply and signal pressures. By-pass and dépressurise the valve body. Step A: Unscrew the two pressure connection nuts (138a) and pull out the tubing (140). Step B: Unscrew the cap screws (141a) and remove the manifold block (144), spring (158), gasket inclusive three O-rings (146), pilot valve assembly (155, 156, 157), shims (145), and O-ring (153). Caution: Handle the shims (145) carefully. Step C : Loosen lock nut (117) and take-up screw (116) and unhook the spring clamp (115) from the lever (22). Step D: Unscrew the cap screws (141b) from the positioner block (147) and remove it from the actuator bracket. Remove the screws (148) to separate the positioner diaphragm assembly (152) and spring (154) from the positioner block. Examine all parts for wear and replace, if necessary.

OIL FLOW METER

OM8160#01.4

INDUSTRIES

Oil flow meter General The oil flow meter unit is equipped with a set of spindles (M), pole wheel (P), and pick-up sensor (I), see also Figure 1. The measuring principle is positive displacement. The oil flow causes the measuring spindles (M) to rotate, and in front of the pick-up sensor (I) the pole wheel (P) is turning in an exactly defined distance (a). The pickup sensor (I) records an impulse for every pole which moves along. This electronic impulse is then sent to the control system. With each rotation an exact volume is given, and by settings in the control system the impulses are converted into a 4-20 mA flow signal. Illustration of the oil flow meter unit

Figure 1

omg03a.cdr

The oil flow meter can be installed in any position. But it must always be free from tensions to prevent distortion of the oil flow meter. Furthermore, it should be located in a position from where it is possible to dismount the pick-up sensor. As shown on the nameplate indicated in Figure 2, both flow directions are possible. But the preferable flow direction is indicated by the all white arrow symbol. The accuracy of the oil flow meter depends on the momentary flow. Figure 3 shows the characteristic for the oil flow meter. The oil flow meter is very sensitive towards larger objects in the oil, and these objects can cause a total blockage of the oil flow meter. To prevent large objects from entering the oil flow meter, the oil system must be provided with a filter (max. 0.3-0.5 mm mesh). The filters located in the oil pump unit will usually provide for an adequate filtration. The dry sleeve is mounted, adjusted, and tested with the pick-up sensor as a unit. The pick-up sensor, including the milled nut and spring, is screwed into the dry

sleeve. The spring must be able to press the pick-up insert smoothly to the front side of the dry sleeve. It is important for the function of the sensor system that the dry sleeve is free of foreign substance. The sensor system is shown in Figure 4. The sensor system (pick-up sensor and cable) must not be in an area of electromagnetic field pulses with high intensity. This could cause measuring errors or even destruction of the sensor system.

Commissioning Step A: Ensure that the oil system has been thoroughly flushed for impurities and that it is free from air.

Note: Impurities cause the oil flow meter to be blocked, and air affects the accuracy of the oil flow meter. Step B: Check that the oil flow meter and pick-up sensor are installed correctly. Step C: Set the values for max. oil and beats/10 litre in the control system. The max. oil value is the maximum oil flow in 1/h at 100% burner load on heavy fuel oil (provided this is the main fuel). The value for beats/litre can be taken from the identification of the oil flow meter (see Figure 2). Step D: Unscrew the pick-up sensor from the oil flow meter. Step E: Tap the pick-up sensor quickly against an object and check that the control system records the signals. Step F: Mount the pick-up sensor again. Step G: Check and adjust the oil flow settings for minimum load, ignition load, etc. in the control system.

Dismounting and mounting instructions For dismounting and mounting the oil flow meter and sensor system please also see Figure 1, Figure 4, Figure 5, and Figure 6.

Dp-transmitter, type 7MF4433 1

General The following description is valid for a differential pressure transmitter SITRANS P, type 7MF4433. Warning: This device may only be assembled and operated after qualified personnel has ensured, by providing suitable power supplies, that no hazardous voltages can get into the device in normal operation or in the event of a failure of the system or parts thereof.

Warning: The device may be operated with high pressure and corrosive media. Therefore serious injuries and/or considerable material damage cannot be ruled out in the event of improper handling of the device. The perfect and safe operation of this equipment is conditional upon proper handling, installation, and assembly as well as on careful operation and commissioning.

Technical description 2.1 Application The SITRANS P transmitter can be used to measure: •

the differential pressure, e.g. the active pressure,

•

a small positive or negative excess pressure,

• flow q ~ p° 5 (together with a flow control valve) of non-corrosive and corrosive gases, vapours, and liquids. Measuring spans are possible between 1 mbar and 30 bar depending on the type. The output signal is a load-independent direct current of 4 to 20 mA. A linear (proportional to the differential pressure) or square rooting characteristic (proportional to the rate of flow) can be selected. Transmitters conforming to the type of protection "Intrinsic safety" and "Explosionproof may be installed within potentially explosive atmospheres zone 1 or zone 0. The transmitter is provided with an EU prototype test certificate and comply with the corresponding harmonised European standards of the CENELEC.

2.2 Mode of operation Figure 1 shows a function diagram of the SITRANS P differential pressure and flow transmitter. The item numbers referred to in the following description are those mentioned in the in the figure. The differential pressure is applied via the diaphragms (4) and the filling liquid (3) to the silicon pressure sensor (7). If the measuring limits are exceeded, the overload diaphragm (6) is flexed until one of the diaphragms (4) rests on the measuring cell body (2), thus protecting the silicon pressure sensor (7) from overloading. The measuring diaphragm of the silicon pressure sensor is flexed by the applied differential pressure. The resistance of four piezo-resistors fitted in the diaphragm in a bridge circuit th+us changes. This change in resistance results in a voltage output from the bridge proportional to the differential pressure. This voltage is amplified and converted into a frequency by means of a voltage-to-frequency converter (9). This signal is evaluated by a micro controller (10), and its linearity and temperature effect corrected. The processed signal is converted by a digital-to-analogue converter (11) into an output signal of 4 - 20 mA. The data specific to the measuring cell as well as the parameters of the transmitter are stored in a non-volatile memory (EEPROM). The cable termination point and the electronics are arranged opposite one another. Parameterisation of the transmitter is performed using a laptop, PC, HART® Communicator, or the input keys. Normally the input keys are used to set-up the transmitter. Function diagram 12

Installation 3.1 Place of installation The transmitter can be installed above or below the pressure tapping point. When measuring gases, it is recommended to install the transmitter above the pressure tapping point and the pressure pipe to be laid so it runs down to the pressure tap. This will permit any condensation in the pipe to drain off and not affect the measurement. When measuring liquids, the transmitter should be installed below the pressure taping point and the pipe laid so it rises up to the pressure tap, thus enabling any gas in the pipe to dispersed. The point of installation should be easily accessible, preferably close to the measuring point and free from vibration. The permitted ambient temperature limits must not be violated. Protect the transmitter from direct heat sources. Before installing the transmitter, compare the process data against the data on the rating plate. Keep the transmitter closed during the installation process. The transmitter can be fitted directly to the valve manifold or secured with a mounting bracket.

3.2 Fixing with a mounting bracket The mounting bracket is fixed to either • a wall or mounting frame using 2 screws, or to • a vertical or horizontal mounting pipe (50 to 60 mm in diameter) using a U-bolt (see Figure 3). The transmitter is fastened to the mounting bracket using the four screws supplied. Fixing the transmitter using a mounting bracket

Warning: Check that the auxiliary power supply matches that specified on the rating plate. The transmitter should be powered from a SELV (safety extra-low voltage) source. If other power sources are used, it is recommended to earth the transmitter housing and PE connection. The earth terminal in the connection box must be connected internally to the PE connection. Please note that: •

The sealing caps in the cable entries have to be replaced by relevant cable glands or blanking plugs, which must be certified when using transmitters conforming to protection type "Flame-proof enclosure".

•

The following general guidelines apply when laying terminal (maximum cross section 2.5 mm2)/signal cables:

— lay the signal cable separately from cables carrying voltages > 60 V — use twisted-pair cables — do not lay cables close to large electrical systems, or use screened cable 3.4.1 Connection to screw terminals Electrical connection

5.2 Operation with LCD display 5.2.1 General •

Please note that the input keys might be disabled. To cancel a set keyboard disable press the "M" key for 5 seconds.

Step A: Undo the two screws holding the protective cover in place, which can then be moved out of the way. Step B: On completion of calibration replace the protective cover and tighten both screws. 5.2.2 Set/adjust start of scale and full scale The start of scale and full scale can be set or adjusted with the input keys. Modes 2 and 3 (see Table 1 ) are available for this. This allows implementation of rising or falling characteristics. Setting (theoretical relationship) In setting, a desired start of scale and/or a desired full scale are assigned to the standard current values (4 mA/20 mA). Pre-requirements: two reference pressures (Pri, Pß) provided by the process or generated by a pressure transmitter. Note: The measuring span is not changed when setting the start of scale. By setting the full scale the start of scale remains unchanged. Therefore the start of scale should be set first and then the full scale. The relationship between the measured pressure and the generated output current is linear. Please note that this does not apply if square rooting characteristic is selected. In case of linear relationship the output current can be calculated with the following equation shown in Figure 11 : Equation for calculation of current output I = output current p = pressure MA=start of scale ME = full scale

Example Given a transmitter with a measuring span of 0 to 16 bar. Set to a measuring span of 2 to 14 bar. Step A: Apply 2 bar process pressure. Set the device to mode 2 with the "M" key. The display shows the set mode at the bottom left. Set the start of scale by pressing the T and 4 keys on the value for about 2 seconds. An output current of 4 m A is then generated at 2 bar input pressure.

Step B: Apply 14 bar process pressure. Set the device to mode 3 with the "M" key. The full scale is set by pressing the t and i keys on the value for about 2 seconds. An output current of 20 mA is then generated at 14 bar input pressure. Step C: The output current for any input pressure can be calculated with the specified equation shown in Figure 11. Adjusting (theoretical relationship) When adjusting, the start of scale and/or the full scale can be assigned to any desired current value using one reference pressure. This function is particularly suitable if the pressures necessary for start of scale and full scale are unavailable. Requirements: applied pressure (reference pressure) and the set start of scale and full scale are known. Please note that after adjusting, the measuring range specified on the measuring point plate may no longer match the setting. Using the following equation shown in Figure 12 the current that should be adjusted for the desired start of scale and full scale can be calculated.

Example Given a transmitter with a measuring span of 0 to 16 bar. Adjust to a measuring span of 2 to 14 bar. A reference pressure of 11 bar is available. Step A: Set the device to mode 2 with the "M" key. Using the equation from Figure 12 first calculate the current that should be adjusted for the desired start of scale (2 bar) at the applied reference pressure and then adjust it with the f and i keys (13 mA in this example). Step B: Set the device to mode 3 with the "M" key. Using the equation from Figure 12 calculate the current that should be adjusted for the desired full scale (14 bar) at the applied reference pressure and then adjust it with the t and i keys (16 mA in this example).

Set start of scale and full scale (practical application with actual pressures available) The device sets the output current for the start of scale to 4 mA and the full scale to 20 mA when the input keys are pressed according to the following instructions. The start of scale is set by: Step A: Apply the corresponding pressure. Step B: Select mode 2 using the "M" key. Step C: Set the start of scale to 4 mA with the t and i keys. StepD: Save with "M". The full scale is set by: Step E: Apply the corresponding pressure. Step F: Select mode 3 using the "M" key. Step G: Set the full scale to 20 mA with the T and i keys. Step H: Save with "M". Set start of scale and full scale (practical application with reference pressure available) If the output current is not set but adjusted continuously, the currents must be calculated so they can be adjusted mathematically. It is possible to make an adjustment for the start of scale, the full scale, or both values one after the other. The start of scale is adjusted by: Step A: Apply the reference pressure. Step B: Select mode 2 using the "M" key. Step C: Adjust the output current for the start of scale with the T and 4- keys. Step D: Save with "M". The full scale is adjusted by: Step E: Apply the reference pressure. Step F: Select mode 3 using the "M" key. Step G: Adjust the output current for the full scale with the t and 1 keys. Step H: Save with "M". 5.2.3 Electric damping The time constant of the electric damping can be set in steps of 0.1 second between 0 and 100 seconds with the input keyboard. This damping acts additionally to the device-internal basic damping. The electric damping is set by:

INDUSTRIES

Step A: Select mode 4 using the "M" key. Step B: Set the desired damping with the T and i keys. Step C: Save with "M". 5.2.4 Blind setting of start of scale and full scale In modes 5 and 6 the start of scale and full scale can be set/adjusted with the input keys and without applying pressure. It is also possible to change between rising and falling characteristics. Theoretical relationship First select the desired physical unit. The two pressure values can then be set/adjusted with the T and -l keys and saved in the device. These theoretical pressure values are assigned to the standard current values 4 mA and 20 mA. The relationship between the measured pressure and the generated output current is linear. Please note that this does not apply if square rooting characteristic is selected. Example Given a transmitter with a measuring span of 0 to 16 bar. Adjust it to a measuring span of 2 to 14 bar without applying pressure. Step A: Set the device to mode 5 with the "M" key. Set the start of scale to 2 bar by pressing the t or 1 key. If 2 bar input pressure are applied later, an output current of 4 mA is generated. Step B: Set the device to mode 6 with the "M" key. Set the full scale to 14 bar by pressing the Î or •I key. If 14 bar input pressure are applied later, an output current of 20 mA is generated. Set start of scale and full scale, blind (practical application) The device sets the start of scale to the lower and the full scale to the upper sensor limit when the keys are operated as follows: The start of scale (blind) is set by: Step A: Select mode 5 using the "M" key. Step B: Press the t and -l keys simultaneously and hold for 2 seconds. The start of scale is set to the lower sensor limit. The full scale (blind) is set by: Step C: Select mode 6 using the "M" key. Step D: Press the T and 1 keys simultaneously and hold for 2 seconds. The full scale is set to the upper sensor limit. Adjust start of scale and full scale, blind (practical application) If the pressures for the start of scale and full scale are not to be set but adjusted continuously, the keys should be operated as follows: The start of scale (blind) is adjusted by: Step A: Select mode 5 using the "M" key.

Step B: Adjust the pressure value of the start of scale with the T or X keys. Step C: Save with "M". The full scale (blind) is adjusted by: Step D: Select mode 6 using the "M" key. Step E: Adjust the pressure value of the full scale with the T or i keys. Step F: Save with "M". 5.2.5 Zero adjustment (position correction) The zero error resulting from the installation position can be corrected with a zero adjustment. To do this, the device must be ventilated to correct the existing offset so that the value 0 bar (or other unit of pressure) appears in the display. The setting of the start of scale and full scale remain the same. The zero adjustment is set by: Step A: Vent the transmitter. Step B: Select mode 7 using the "M" key. Step C: Set zero with the Ï and 4 keys. Step D: Save with "M". 5.2.6 Current transmitter The transmitter can be switched to constant current mode with the "M" key. In this case the current no longer corresponds to the process variable'. The following output currents can be set independently of the input pressure: — 3.6 mA - 4.0 mA - 12.0 mA - 20.0 mA - 22.8 mA The current transmitter function can be cancelled again with the "M" key. The constant current is set by: Step A: Select mode 8 using the "M" key. Step B: Activate the constant current mode by pressing the Î and i keys simultaneously for about 2 seconds. Step C: Activate the constant current level by pressing the t or 4 key. Step D: Turn off the constant current mode with the "M" key. Step E: Exit the constant current mode with the "M" key. 5.2.7 Failure current In mode 9 it is possible to select whether the upper or lower fault current should be the output in the event of a fault or an alarm. The current can be set to 3.6 m A or 22.8 mA. The default is the lower fault current. The fault current is set by:

Description 2.1 Field of application The PREMIO linear thrust actuators are employed to actuate control or shut-off valves requiring a nominal linear stroke distance of up to 80 mm and thrust from 2.2 kN to 15 kN. The thrust actuators are set to the thrust forces specified in the technical data. If supplied with the valve, the lift of the thrust actuator will be set to the stroke distance of the valve. Selection of the proper actuator version in alignment with the corresponding fitting as well as use of the thrust actuator in accordance with the specified technical data is the responsibility of the systems engineer. Attention: Any use of the thrust actuator beyond the specified technical data or improper use of the actuator is deemed to be not for the intended purpose. The ambient conditions have to be conformed to the actual electromagnetic compatibility directives. Additional the compatibility to this directive has to be maintained in case of expansion or other changing of the ambient conditions.

2.2 Method of functioning The thrust actuator, fitted with a yoke or columns, is mounted to the valve. Transfer of force is affected via a coupling safeguarded against torsion. The torsion safeguarding feature also serves as a lift indicator. The lift settings can be read off on a lift dial attached to the yoke or between the 2-ear clamps mounted to the column. The electrical components are accommodated separately from the gearbox underneath a sealed hood, thus being protected against operating and environmental effects. Following removal of the hood, easy access is provided to the switch gear and indicating feature. The rotary motion of the motor is transmitted to the spindle nut by means of spur gear. The drive spindle, which is safeguarded against torsion, screws its way into the spindle nut and thus performs a pull or push motion depending on the sense of rotation. In the final positions of the valve, the spindle nut is pressed against a set of springs so as to produce closing force. The motor is switched off by means of two load-dependent switches and one strokedependent switch. The load-dependent switches will also switch off the motor if foreign bodies have lodged themselves between the valve seat and cone. The load-dependent switches serve to protect the valve and thrust actuator against damage.

2.3 Technical data The technical date for the thrust actuators is appears from Table 1. Actuator diagrams are illustrated in Figure 1 and Figure 2 and the part list is shown in Table 2. Finally a dimension drawing can be found in Figure 3.

Installation Note: Safe operation of the actuator is only ensured if it is installed, put into operation, and maintained by qualified personnel. In addition, care must be taken to ensure that the general equipment and safety regulations for electrical lines and installations are complied with and that tools and protection devices are used professionally. The operating instructions for the electronic actuator must be observed when carrying out all work on and when handling the electronic actuator. Disregard of these instructions can result in injury to persons or damage to property.

3.1 General installation notes In addition to general installation guidelines, the following points are required to be observed: — Existing operating instructions for valve. — Complete valve with cross-arm. — Valve cone approximately in mid lift position - on no account supported inside a seat. — Electrical installation in accordance with DIN VDE 0100 and regulations of the local electricity generating board. — Conductor cross-section selected to correspond to the given drive power and existing line length. — Mains fuse rating max. 6 A. — Circuit breakers to EN 60335-1 in the plant to cut off the mains supply to the actuator. — Conformity of technical data on thrust actuator with field conditions. — Mains voltage in accordance with data specified on rating plate of thrust actuator. — Thrust actuator complete with yoke or distance columns and coupling parts intended for mounting to the corresponding valve. — Qualified personnel possessing knowledge of the regulations pertaining to the erection of power installations. — Ease of access to installation site and adequate clearance space above the thrust actuator for removing the hood. — Install where there is protection against high-energy heat radiation. — The ambient temperature must not exceed +70°C. — In case of widely fluctuating ambient temperatures and high atmospheric humidity, user is recommended to install a heating resistor to minimise condensation build-up in the actuator.

In the manual operating mode pay careful attention in the final positions that the hand wheel is only turned to the point where the torque switch trips (audible click) as otherwise damage will be caused to the thrust actuator. Since the hand wheel always follows during motor-driven operation (running indication), never operate by hand while the motor is running -potential injury hazards. For actuators type 12.0 -15.0 kN With the motor in the stationary state, the thrust actuator can be run in the open and closed state with the engage able hand wheel. Proceed as follows: Step A: Fold the turning handle out of the hand wheel (A), see Figure 5. Step B: Turn the hand wheel slightly and push in the engaging button for manual mode (B) --> the button engages. — Turning in clockwise direction —> closes valve. — Turning in counter-clockwise direction —> opens valve. The motor is no longer in mesh when the hand wheel is engaged. The hand wheel is automatically disengaged when the motor starts and the hand wheel is once more in mesh. Language UK

Settings 4.1 Torque and travel switches -standard feature Thrust actuators are as standard equipped with a load-dependent travel switch for the closing direction (SI), a load-dependent travel switch for the opening direction (S2), and a stroke-dependent travel switch for the opening direction (S3). The loaddependent travel switches (SI, S2) switch off the motor as soon as the factory-set thrust force is attained. Note: The settings of the load-dependent travel switches must on no account whatsoever be changed. The stroke-dependent travel switch (S3) switches off the motor as soon as the lift or stroke is attained. If the thrust actuator is supplied on a straight-way valve, the stroke-dependent travel switch S3 is set in such a way that the motor of the thrust actuator is switched off as soon as the maximum valve-lift is attained. If the thrust actuator is supplied on a three-way valve, the trip cam belonging to travel switch S3 is set in the opening direction in the trip slide to such a downward extent that the upper final position of the valve is attained prior to travel switch S3 being reached, thus causing the load-dependent travel switch S2 to switch off the motor. For this function, all three switches reveal interlock-controlled circuitry on the board. If the standard travel switches are to be integrated directly into the facility control system, the standard board can be replaced by optional boards PA or NA (only 2.2-5.0 kN).

4.2 Connection boards PA or NA (only 2.2 - 5.0 kN) On connection boards PA or NA, the standard travel switches S11/S21, S12/S22, and S13/S23 do not reveal interlock-controlled circuitry and can be integrated individually into the facility control system. The 3 contacts on each of the switches SI 1/S21, S12/S22, and S13/S23, designed as double-throw contacts, are, in the case of these boards, brought out on terminals 40 - 48 and can be freely connected. The switches on the PA optional board (standard-voltage connection board) are designed for switching capacities of up to 10 A, 250 Vac. The switches on the NA optional board (low-voltage connection board) are designed for switching capacities of up to 0.1 A, 4 - 30 V (gold contacts). The optional boards may only be installed at the factory due to the switching points of the load- dependent switches having to be reset following installation of these boards. Note: When using optional boards PA or NA, it must be warranted -due to the operator's individual circuitry- that, when switching the load-dependent travel switches Sll/21, S12/S22, and S13/S23 the motor of the thrust actuator comes to a standstill without delay. This function is not provided for on the optional boards PA and NA in the supplied state.

4.3 Setting of standard travel switch (S3) On delivery of the thrust actuator, the standard travel switch (S3) is already set to the existing valve-lift and the setting spindle for the travel switch (S3) is sealed with screw glyptal. This setting needs no changing for normal operation. If reinstalling the thrust actuator on a straight-way valve, the travel switch (S3) needs to be set as follows: Step A: Move valve out of the lowest position so as to run valve-lift to up position. Step B: Using a screw driver, proceed to turn setting spindle for switch (S3) until the trip cam arriving from below trips the switch (audible click). Step C: Run thrust actuator briefly in closing direction and then in opening direction once more, checking to see whether the thrust actuator is switched off at the desired point (nominal lift). Step D: If needed, correct the setting as described. If reinstalling the thrust actuator on a three-way valve, the travel switch (S3) needs to be set as follows: Step E: Run valve in both final positions and check in each final position whether the valve switches off via the load-dependent switches. Step F: Carry out a check in the top final position the see whether, after switching off the thrust actuator, the trip cam of the travel switch (S3) is situated below switch (S3) and has not tripped the latter. If the trip cam is situated above the travel switch (S3) or trips the same, the setting spindle governing the travel switch (S3) needs to be turned until the trip cam is situated below travel switch (S3) without tripping it. Step G: Run the thrust actuator in both final positions once more and check whether thrust actuator switches off in both final positions via the load-dependent switches. Step H: If needed, correct the setting as described above.

4.4 Potentiometers The potentiometers are used for electrical position acknowledgement on the facility control system or for the options, electronic position controller ES11 or electronic position indicator RI21. A maximum of 2 potentiometers can be installed (= 1 double potentiometer). The potentiometers can be supplied with different resistance values. For the electronic position controller ESI 1 and the electronic position indicator RI21 use must be made solely of 1000 ohm potentiometers. Conversion of the relevant valve-lift to the potentiometer angle of rotation is effected by means of transmission determined in respect of each valve-lift between the toothed rack on the trip slide and the pinion on the potentiometer shaft. Use must only be made of the pinion specified for the valve-lift.

If the thrust actuator is supplied with the valve and built-in potentiometer, the potentiometer is assembled and set ready for operation. To achieve optimal electromagnetic compatibility it is recommended to use shielded cables for connecting potentiometers or standardized active current or voltage signals. 4.4.1 Installing the potentiometer If retrofitting the potentiometer, proceed as follows: Step A: Switch off mains voltage and safeguard to prevent it from being switched back on again accidentally. Step B: Loosen countersunk screw in hood, carefully remove hood. Step C: Plug in the flat connectors on grey potentiometer cables onto the middle connector pins, those of the red cables onto the upper connector pins and those of the yellow cables onto the lower connector pins of the potentiometer (see Figure 10, Figure 11, and Table 3). Step D: Insert the potentiometer into the guide in the way that the pinion (50.73) of the potentiometer meshes with the gear stick of the trip slide. Step E: With a valve lift up to 30 mm, hook spiral spring (50.70) into the left-hand window of board support (50.42) above the potentiometer guide, insert into the guide between the slide block and the potentiometer guide and hook into the cut-out below the potentiometer. Step F: With a valve lift between 30 mm and 50 mm, hook spiral spring (50.70) into the right-hand window (for 12.0 - 15.0 kN middle window) above the potentiometer guide, insert into the guide between the slide block and the potentiometer guide and hook into the cut-out below the potentiometer. Step G: With a valve lift between 50 mm and 65 mm, hook spiral spring (50.70) into the middle window in board support (50.42) above the potentiometer guide, insert into the guide between the slide block and the potentiometer guide and hook into the cut-out below the potentiometer. Step H: Check to see whether pinion (50.73) is pressed into toothed rack by spiral spring (50.70) and is positioned free from backlash. Step I: If this is not the case, remove spiral spring (50.70), readjust by bending a little, and place back in position again. Step J: Screw jack strip of connecting cable (50.68) to board support (50.42) with two self-tapping screws (50.69), (single potentiometer connectors 25-27). Step K: Insert additional 3-pole connector (50.74) in jack strip of connecting cable (50.68). Step L: Set potentiometer. Step M: Place hood carefully onto thrust actuator and fasten it on the actuator with rubber gasket and countersunk screw.

Step C: Using a screw driver, turn slotted potentiometer shaft in counter-clockwise direction until reaching the travel stop. This places the potentiometer in the initial position (approx. 0 ohm). Step D: For checking purposes, the resistance of the potentiometer needs to be measured using an ohmmeter. Step E: Measure the resistance on potentiometer 1 between terminals 25 and 26. Step F: Measure the resistance on potentiometer 2 between terminals 28 and 29. Step G: In this position of the actuator, the measured value should be approx. 0 ohm. Step H: Run thrust actuator to upper final position and read off corresponding resistance value on ohmmeter. Step I: The resistance values thus measured need to be taken into account for the settings to the facility control system.

Starting up Check the following before starting up a new system or restarting a system after repairs or conversion: • Correct completion of all installation/assembly work. •

Circuits of the system in accordance with DIN VDE regulations and regulations of the relevant power supply company as well as compliance with all safety regulations.

•

Hood of thrust actuator assembled.

•

Start up only by qualified personnel.

Warning: While in operation, the thrust actuator has moving and rotating parts as well as being integrated in an electrical network system. Improper handling or failure to observe the operating instructions or the valid regulations may lead to death, grievous bodily injury or substantial property damage When placing into service proceed as follows: Step A: Use the hand wheel, to run the thrust actuator to approximately mid lift position. Step B: Apply brief pulses to the thrust actuator for each direction of movement and check whether the directions of movement correspond to those desired. If this is not the case, the pulse lines governing the opening and closing action must be exchanged on the thrust actuator.

Step C: Run thrust actuator to the final position in each direction of movement and check whether it switches off automatically and whether all externally moving parts are able to move freely. Step D: If failing to function properly, check all installation and setting work previously carried out, correcting if necessary, and afterwards place into service once again.

Care and maintenance The thrust actuator requires very little maintenance. Accordingly maintenance in specified intervals is not necessary. The thrust actuator must not be cleaned with high-pressure equipment or aggressive solvents or detergents injurious to health or highly inflammable. During and after cleaning, an inspection should be carried out of the sealing points on the thrust actuator. If there is any sign of lubricant escaping or dirt having accumulated, the sealing elements must be repaired.

Dismantlement of the thrust actuator In addition to general installation guidelines, the following points are required to be observed: • Dismantlement of the thrust actuator from the fitting must only to be carried out by suitably qualified personnel. •

The supply line for connecting up the thrust actuator must be in the dead state i.e. disconnected while dismantlement work is being carried out. After being disconnected, the mains power must be prevented from being switched back on again accidentally.

•

The system must be run down (depressurised state) as the valve cone is not held without the thrust actuator and would thus be conducted by the system pressure.

•

Valve cone approximately in mid lift position - on no account supported inside a seat. To dismantle the thrust actuator proceeds as follows: Step A: Loosen counter-sunk screw in hood, carefully remove hood. Step B: Disconnect all cables led into thrust actuator from outside and remove from thrust actuator. Step C: Place hood on carefully from above and fix in place with counter-sunk screw and rubber gasket. Step D: Loosen grub screw inside torsion safety feature; screw coupling out of torsion safety feature. Step E: Loosen clamping bolts connecting the thrust actuator to the fitting. Step F: Remove thrust actuator from valve. Language UK

Control valves, type 470/471 1

General This type of control valve is suited to regulate fluids, gases and steams. The valve plug is normally a parabolic plug, but can also be supplied in a perforated design. Both types of plugs can have either linear or equal percentage flow characteristic. The flow direction for parabolic plugs is always against the closing direction. However, with perforated plugs for steam and gases, it is in the closing direction. If a valve with a perforated plug is operated by means of a pneumatic actuator with the flow in the closing direction, the pneumatic actuator should have a stronger thrust force. This is necessary to prevent thumping near to the closing position. All control valves can be fitted alternately with manual-, pneumatic-, electric- or hydraulic operation devices.

Operation 2.1 Fitting instructions The valve should be inserted so that the spindle has a vertical position together with the actuator. The valve can also be tilted to a maximum horizontal position if the installation point does not allow any better condition. To guarantee a disturbance free function of the control valve, the inlet and outlet stretches of the piping should be of straight piping length (min. two times the pipe diameter by inlet and six times by outlet). The piping should be rinsed to clear out any pollution, welding beads, rust, etc. before inserting the control valves. A strainer should be fitted in front of the control valve to catch the remaining particles. Bolts should be tightened after taking into operation. The flow direction is signalled by an arrow on the valve body. The valves should be insulated against high temperatures to guard the actuator. 2.2 Actuator assembly The control valves are normally delivered with actuators already fitted. For alternations or maintenance of actuator, the assembly should occur in accordance with the operation instructions for the actuator. 2.3 Setting into operation When the piping system isfilled,the spindle sealing should be checked for leakage and, if necessary, tightened. A PTFE-V-ring unit does not require any tightening as the spring tension maintains the necessary force. The bolts must be tightened gradually in steps, diametrically in pairs, but not tighter than it is necessary for the sealing. Flange connection bolts should never be loosened or tightened when the valve is under temperature or pressure even if a leakage may arise. For actuators please see to the appropriate actuator operation instructions.

Maintenance Before any maintenance of the control valve is carried out, the piping system must be shut off and pressure free.

3.1 Exchange of the stuffing-box packing A leak stuffing-box packing should initially be carefully tightened to stop the leakage. If this does not help, a new layer should be inserted, or the complete packing should be replaced. 3.1.1 Additional packing layer Step A: Open the valve fully and unscrew the hexagon nuts (17). Step B: Lift the gland flange (7) and the spindle guiding (8) upwards. Step C: Insert adequate quantity of packing rings (split ring-displacement, splitting at 180° to avoid overlapping). Step D: Fix the hexagon nuts (17) properly. 3.1.2 Exchange Step A: Drive the actuator into middle position and dismantle the actuator. Step B: Unscrew the hexagon nuts (17) from the studs (15). Step C: Remove the gland flange (7), the spindle guiding (8) and the old stuffing box (10) and clean the packing compartment. Step D: Clean the valve spindle and check for damage and if necessary replace. If the damaged spindle is not replaced, the new packing will leak after a short period. Step E: Insert the new packing rings (split ring-displacement, splitting at 180° to avoid overlapping). Step F: Fix the hexagon nuts (17) properly.

Note: Strenuous tightening will prevent leakage, but will also have a brake effect on the spindle which aggravates the movement of the spindle.

3.2 Exchange of a PTFE-V-ring sealing unit A PTFE-V-ring unit is spring loaded and has enough set pressure to ensure a good seal even by low operation pressures. It is replaced as mentioned above. The PTFE-V-ring sealing unit should be lubricated before it is inserted. The sealing lips must face against the pressure direction. Language UK

Note: Special care should be given to the spindle surface. Rough surfaces wear the sealing lips enormously and can be due to failure of the packing unit.

3.3 Exchange of the bellow unit Step A: Drive the actuator into middle position and dismantle the actuator. Step B: Unscrew the screw joint (7.1). Step C : Unscrew the hexagon nuts (17) and remove the bellow housing (25). Dismantle the plug as described in the next section. Step D: Unscrew the hexagon nuts (17.1) and dismantle the mounting bonnet (3.1). Step E: The bellow unit (26) is removed from the bellow housing (25). Step F: Replace the two gaskets (14.1) and the gasket (14). Step G: When the bellow unit (26) is replaced, the proper position of the antitwisting device must be observed. Step H: The set pins (21) have to drive within the slots of the anti-twisting device. Check for friction-free movement. Step I: Replace mounting bonnet (3.1) and screw down the hexagon nuts (17.1) crosswise.

3.4 Exchange of the plug-spindle unit Step A: Drive the actuator into middle position and dismantle the actuator. Step B: Unscrew the gland flange (7). 3.4.2 Control valve type 470 Step A: Unscrew the hexagon nuts (17) and dismantle the mounting bonnet (3). Step B: Pull out the plug with the spindle and exchange this unit. Step C: Remove the spring-type straight pin (19) and unscrew the spindle (6). Step D: Replace the old parts and assemble it. Step E: Drill a hole through the plug shaft and insert a new pin. Step F: Replace the gasket (14) and assemble the mounting bonnet (3). Step G: Tighten the nuts (17) evenly, crosswise.

1.1 Function When the pump is started, oil is drawn through the suction side port "S" via the filter "H" to the suction side of the gearwheel set "C" as shown in Figure 2. The gearwheel set pumps the oil to the pressure side. Language UK

Page 1/3

AALBORG


INDUSTRIES

OM5540#10.1

The pressurised oil is led to the cut-off and regulating valve "V". When the opening set point is reached, the valve opens. Hereby oil is distributed to the nozzle port "P" and to the pump return side "R" via the shaft seal "F". The pressure is controlled and maintained at a constant level by the regulating valve "V". The opening set point can be adjusted by means of an Allen key. The quantity of oil supplied to the nozzle port "P" is determined by the pressure set on the regulating valve "V" and the resistance in the nozzle line and the oil nozzle. When the pump is stopped, the pump output drops and produces a drop in the oil pressure. The spring in the regulating valve presses the regulating piston forward until it seats in port "P". This cuts the oil flow to the nozzle and ensures that the line is effectively shut off. Sketch of the oil pump system

Figure 2

ignibupl.tif

If the pump is overloaded, i.e. more oil is demanded than the gearwheel is able to pump under the given conditions, the oil pressure falls below the set value because the regulating valve piston moves towards its closed position and partially or wholly cuts off the return oil via port "O". This condition can be remedied by:

Language UK

•

Reducing the pump pressure

•

Reducing the capacity, i.e. smaller oil nozzle or larger resistance

•

Changing to a pump with higher capacity

OM5540#10.1

INDUSTRIES

1.2 Commissioning When the pump is commissioned, the pump and the pipe system must be filled with oil and ventilated. The pump can be ventilated on the ventilating screw "M". If the pump is running without oil for more than five minutes, it may cause damage to the pump.

1.3 Pipe systems One pipe system is used when the pump is placed lower than tank level (positive suction head). Two pipe system is used when the pump is placed higher than tank level (negative suction head). In two-pipe systems the oil is returned direct to the oil tank. In one-pipe systems the setting screw "A" must be removed to give free flow to the suction side via by-pass "G" with return port "R" closed. Normally the pump is delivered as a one-pipe system. The pump is delivered with two suction ports and two return ports.

COMBUSTION AIR FAN

OM5550#01.2

I N D U S T R I E S

Combustion air fan 1

General The purpose of the combustion air fan is to supply combustion air to the burner. The air is supplied by a directly driven centrifugal fan. The fan is mounted on a common bed frame with motor, inlet vanes, and servo-drive unit. The fan impeller inside the spiral housing is mounted directly on the motor shaft. The air flow to the burner is regulated by inlet vanes mounted on the fan suction side. The inlet vanes are of a multi-blade design and regulated by a servo-driven unit comprising an air cylinder and I/P positioner. A silencer can be mounted on the fan suction side. Figure 1 shows an illustration of the combustion air fan (shown without silencer) and the location of markings and warning signs. Illustration of the combustion air fan

Storage If the combustion air fan unit is stored for a period of time prior to installation, a number of initiatives must be observed and considered. They are described in the following sections. 2.1.1 Combustion air fan (normal conditions) When the combustion air fan unit is delivered, it is provided with the correct quantity and type of grease. The optimum storage temperature is 15°C.

Language UK

OM5550#01.2

COMBUSTION AIR FAN

INDUSTRIES

The impeller axle must be rotated at regular intervals during storage. This prevents the motor bearings from being damaged if the axle is kept in the same position constantly. The maximum rotation interval is 4 to 5 weeks. 2.1.2 Combustion air fan (extreme conditions) Storage at temperatures above +35°C and below -5°C have a negative effect on the state of the bearing grease. By storage in these conditions the maximum rotation interval is 2 to 3 weeks. After start-up of the combustion air fan the motor bearings (if provided with lubricating nipples) should be greased with a small quantity of grease (4 to 5 grease gun shots). 2.1.3 Prolonged standstill Rotate the impeller axle at the intervals described above.

Installation The fan unit must be placed on a plane and sufficiently strong surface. For repair purposes the distance from the fan unit to the surrounding walls must be sufficient to disassemble any parts of the fan unit. Normally the combustion air fan is fixed to the bed at delivery. However, the vibration dampers are supplied loose. Before installing the fan unit, the vibration dampers must be fixed to the bed by means of the included bolts. The position of the vibration dampers can be seen in the fan drawing. After fixing the vibration dampers to the bed, place the fan unit on the installation place and mark out the bolt holes which fix the dampers to the surface. This will prevent twisting of the rubber compartment. When fixing the fan unit to the surface, use an adequate size of bolts. 3.1.1 Connection of the motor Figure 2 shows the possible wiring connections at the terminal rows of the motor.

Prior to start-up Prior to the first start-up of the combustion air fan, the following procedures must be performed: • Check that the combustion air fan and the air duct system have been installed and supported correctly. If possible, an inside inspection of the air duct system should also be carried out to ensure that it is free from obstacles, e.g. loose parts, insulating material, etc. •

Check that the inlet net has been mounted.

•

Check that the electrical wiring at the terminals of the combustion air fan is performed according to the wiring shown in the electrical diagrams.

•

Adjust the circuit breaker for the combustion air fan to suit full load current of the motor. The current appears from the motor identification plate and/or the electric diagrams.

•

Commission the I/P positioner and dp-transmitter and check that the micro switch, which controls the closed position of the inlet vanes, is activated.

•

Rotate the combustion air fan by hand to ensure a free and an uninterrupted rotation.

•

Ensure that all safety circuits are activated and functional.

•

Ensure that all loose items have been removed in the proximity of the suction side of the combustion air fan.

•

Ensure that the operating personnel have been notified about the coming start-up and that the location of the emergency switches is known to the personnel.

Initial start-up When the combustion air fan is started for the first time, the following procedures must be performed: • Start the combustion air fan and check that it is running with the correct direction of rotation (see the direction arrow).

Language UK

•

Check that the combustion air fan and the air duct system do not produce any abnormal mechanical noise.

•

Check the combustion air fan and the air duct system for any abnormal vibrations.

•

Check the air duct system for leaks.

•

Set the fan load to approximately 10-15%. Check the temperature of the fan bearings. The bearing temperature must be at a constant level after approximately 30 minutes of operation. If the temperature continues to increase, stop the combustion air fan and check the bearings.

•

Set the fan load to 100%. Check the current consumption of the combustion air fan. The current must not exceed the full load current stated on the motor identification plate and/or the electric diagrams.

•

Set the fan load to 0% (inlet vanes closed) and stop the combustion air fan.

Normal operation To ensure a safe and reliable function of the combustion air fan, inspection must take place with frequent intervals as described below. Step A: Check the motor temperature (maximum 80°C). Step B: Check for vibrations by touching the combustion air fan. Step C: Check that the vibration absorbers and flexible connection are intact. Note: If a fault is observed, it must be corrected at once.

Vibration control If the fan is operating in a dusty and/or fatty air environment, coats may occur on the impeller. This might cause abnormal vibrations, which eventually will cause breakdown of the combustion air fan. The cause must be examined immediately. At the factory the fan has been weighed statically and dynamically in accordance with the VDI 2056 - G, Standard. Figure 3 shows vibration curves for the fan according to VDI 2056-G Standard.

Maintenance 8.1 Cleaning of impeller Step A: Ensure that the combustion air fan is not unintentionally started during this repair work. Step B: Access to the impeller is obtained by dismounting the clean-out door. Step C: The cleaning procedure can be performed with a high-pressure cleaner combined with scraping of the rebellious coat. In connection with this ensure that any water in the spiral casing is drained off. Step D: Before starting the combustion air fan again, it is important to check that the impeller is clean and that the dismounted parts have been remounted.

Note: If the impeller has not been carefully cleaned, the residual coat might cause a lack of balance. If the vibration level exceeds the maximum level of 11 mm/s, it might result in a breakdown of the combustion air fan. Therefore, it is important to take precautions by inspecting the impeller before starting up.

8.2 Dismounting of impeller The impeller is mounted directly on the motor shaft. The dismounting of the fan impeller are described below and illustrated in Figure 4. Step A: Ensure that the combustion air fan is not unintentionally started during this repair work. Step B: Dismount the nuts which fix the front plate. Remove the front plate by means of a lifting device or tackle. Step C: Dismount the end bolt and plate of the shaft, and replace the end bolt by a similar short bolt. Step D: Mount a wheel-puller. The impeller is provided with threaded wholes (MIO) located on the hub plate. Tighten the wheel-puller until the impeller is loose. Step E: Then dismount the wheel-puller and end bolt. Finally, the impeller can be pulled out from the spiral casing.

Positioner, SIPART PS2 6DR5000 1

General The following instruction is a general description of SIPART positioners and covers the complete range in the PS2 6DR5000 series. The electronic pneumatic positioner is used as the final control element of a pneumatic linear actuator or a part-turn actuator (rotary movements). The positioner converts a current output signal (4 to 20 mA) from a process controller or control system to a set point value and into a corresponding movement. The positioner changes the pressure in a pneumatic actuator chamber or cylinder until the position corresponds to the set point value. The positioner can be set up either as a single-action positioner or a double-action positioner. The single-action positioner is mainly used together with a control valve. The opposite movement for the control valve is supplied by means of springs. The double-action positioner is mainly used to control an air damper via a pneumatic cylinder (actuator). All movements of the pneumatic cylinder are supplied by the positioner. An illustration of the function diagram for the positioner is shown in Figure 1. The function diagram is shown with option modules.

1.1 Mode of operation Comparison of the set point and the actual value takes place electronically in a micro controller. If the micro controller detects a deviation, it uses a 5-way switch procedure to control the piezoelectric valves, which in turn regulate the flow of air into the actuating chambers. When connected in a two-wire system, the SIPART PS2 draws its power exclusively from the 4 to 20 mA set point signal. The piezoelectric valve converts the command into a pneumatic positional increment. The positioner outputs a continuous signal in the area where there is a large control deviation (high-speed zone). In areas of moderate control deviation (slow-speed zone) it outputs a sequence of pulses. No positioning signals are output in the case of a small control deviation (adaptive or variable dead zone). Commissioning (initialisation) is carried out automatically to a large extend. During initialisation, the micro controller automatically determines the zero, full-scale value, direction of action, and positioning speed of the actuator. It uses these to determine the minimum pulse time and dead zone, thus optimising the control. The positioner can also be operated manually by the pushbuttons and the LCD of the SIPART PS2. The installation of the positioner must be carried out in the following order:

Step C: Push the roll (5), spring (13), and guide washer (22) onto the pin (4). StepD: Insert the pin in the lever (6) and assemble with nut (18), spring washer (14),andU-washer(12). Step E: The value of the stroke range specified on the actuator should be set or if this does not exist as a scaling value, the next greatest scaling value should be set. The centre of the pin must be in line with the scaling value. The same value can be set later under parameter "3.YWAY" in commissioning to display the way in [mm] after initialisation. StepF: Assemble the hexagon socket cap screw (17), spring washer (16), washer (12), and square nut (19) on the lever. Step G: Push the pre-mounted lever onto the positioner axis up to the stop and fix with the hexagon socket cap screw (17). Step H: Fit the mounting bracket (1) with two hexagon head screws (9), lock washer (10), and flat washer (11) on the rear of the positioner. Step I: Selection of the row of holes depends on the width of the actuator yoke. The roll (5) should engage in the pick-up bracket (2) as close as possible to the spindle but may not touch the clamping assembly. Step J: Hold the positioner with the mounting bracket on the actuator so that the pin (4) is guided within the pick-up bracket (2). Step K: Tighten the pick-up bracket. Step L: Position the mounting parts according to the type of actuator. — Actuator with ledge: hexagon head screw (8), flat washer (11), and lock washer (10). — Actuator with plane surface: four hexagon head screws (8), flat washer (11), and lock washer (10). — Actuator with columns: two U-bolts (7), four hexagon nuts (21) with flat washer (11), and lock washer (10). Step M: Secure the positioner onto the yoke using the previously positioned mounting parts.

Note: Set the height of the positioner so that the horizontal lever position is reached as close to the stroke centre as possible. The lever scale can be used as orientation. It must be guaranteed that the horizontal lever position is passed through within the stroke range.

2.2 Mechanic connection to a pneumatic cylinder The positioner is connected to a pneumatic cylinder by means of fixing bracket, lever arm with Allen screw, extension arm, and roller. The pneumatic piston is connected to a guide rail with an oblique angle via a linkage. The guide rail moves together with the piston, and the roller/lever connection senses the position of the piston. By operating both sides of the pneumatic cylinder, the set point is reached. A spring inserted between the fixing bracket and the lever arm secures that the roller is pressed down against the guide rail.

2.3 Mechanic connection to a rotary actuator Figure 3 shows the mechanic connection of the positioner to a rotary actuator. Step A: Attach the mounting console (9, actuator specific) onto the rear of the positioner and secure using the hexagon head screws (14) and lock washers (15). Step B: Adhere pointer (4.2) onto the mounting console in the centre of the centring hole. Step C: Push coupling wheel (2) onto the positioner axis, pull back by about 1 mm and tighten the hexagon socket head screw (18) with the Allen key provided. Step D: Place the carrier (3) onto the end of the actuator and secure using Fillister head screw (16) and washer (17). Step E: Carefully place the positioner with mounting console onto the actuator such that the pin of the coupling wheel engages in the driver. Step F: Align the positioner/mounting console assembly in the centre of the actuator and screw tight (screws are not included in the delivery, they are part of the actuator mounting console). Step G: Follow the start-up sequence as described later. Drive the actuator to the end position and adhere the scale (4.1) onto the coupling wheel (2) according to the direction of rotation and rotary actuator. The scale is selfadhesive.

Pneumatic connection Ensure that the air quality is suitable. Grease-free instrumental air with a solid content < 30 um and a pressure dew point 20 K below the lowest ambient temperature must be supplied. Warning: For reasons of safety, pneumatic power may only be supplied after assembly when the positioner is switched to operating level "P manual" operation with electrical signal applied.

4.1.1 Selection of P manual mode Before pneumatic power is connected, the positioner must be in P manual mode. The display must show "NOINIT" in the bottom line.

4.1.2 Pneumatic connections Figure 4 shows a view of the positioner controls and connections. Step A: If required, connect a manometer block for supply air and actuating pressure. Step B: The silencer in the exhaust output can be removed if necessary. Step C: Connect actuating pressure Yl and/or Y2 (Y2*} is only used with doubleacting actuators) according to the desired safety position. Step D: Connect the supply air (1). The pressure should be between 1.4 to 7 bar.

Note: In order for spring-loaded pneumatic actuators to be able to reliably exploit the maximum possible actuating path, the supply pressure must be sufficiently greater than the maximum required final pressure of the actuator.

4.1.3 Safety position when the electric power supply fails For a single-action actuator is Yl deaerated. For a double-action actuator is Yl equal to the supply air pressure and Y2 is deaerated. 4.1.4 Restrictors To increase the positioning times for fast actuators when necessary, the air flow can be reduced with the restrictors Yl and Y2 (only for double-action valves). Turning the restrictors in the clockwise direction reduces the air flow until it is shut off. To set the restrictors it is recommended to first close them and then open them again slowly (see initialisation process RUN 3). 4.1.5 Purging air switchover The purging air changeover switch located above the pneumatic terminal block on the valve manifold can be accessed when the housing is open. When the switch is in position "IN" the interior of the housing is purged with very small quantities of clean and dry instrument air. In position "OUT" the purging air is led directly out of the instrument.

Commissioning Commissioning (initialisation) is carried out automatically to a large extend. During initialisation, the micro controller automatically determines the zero value, full-scale value, direction of action and positioning speed of the actuator. It uses these to determine the minimum pulse time and dead zone, hereby optimising the control. The positioner can also be operated manually by the pushbuttons and the LCD of the SIPART PS2. The commissioning of the positioner can be divided into the following steps: •

Step C: Without initialisation the positioner is in "P manual mode" and "NOINIT" flashes in the display. This level can also be reached by using "55.PRST" function (see Table 1). Step D: Check the free running of the mechanics in the whole actuating range by moving the actuator with the keys " Î " and " j " and driving to the respective end position. Step E: With linear actuators drive the actuator to horizontal lever position. The display must indicate 48% to 52%. If necessary, correct the value by adjusting the sliding clutch. After the check is completed, the actuator must be approximately half way along its stroke. This is due to establishment of the action direction during automatic initialisation.

5.2 Automatic initialisation Figure 6 shows the configuration mode including the operation in this mode and Table 1 shows the parameter/configuration list. Figure 7 shows the initialisation process of the positioner. The initialisation process is stored in the microprocessor. This means that an additional initialisation only is necessary if any parts of the unit have been changed. Note: The numerical values used in Figure 5, Figure 6, and Figure 7 are examples. Step A: Call the configuration mode by pressing the hand symbol key for longer than 5 seconds. Step B: Set the actuator type, linear or part-turn, in the menu item line "l.YFCT". Step C: Switch to the second parameter by pressing the hand symbol key briefly. Step D: Set the rated angle of rotation for feedback in the menu item line "2.YAGL". It is vital that this value corresponds to the setting of the gear transmission ratio selector (Figure 4, position 8), 33° or 90°. Step E: Switch to the next parameter by pressing the hand symbol key briefly. Step F: This parameter ("3. Y WAY") is only set for linear actuators and if the total stroke in mm should be displayed at the end of the initialisation phase. To do this, select the same value in the display to which the carrier pin to the scale on the lever is set to. Step G: Switch to the following parameter by pressing the hand symbol key briefly. Step H: Start the initialisation ("4.INITA") by pressing the "f" key for longer than 5 seconds.

Step I: During the initialisation phase "RUNl" to "RUN5" appear one after another in the bottom of the display. Please note that the initialisation process may last up to 15 minutes depending on the actuator.

Note: The ongoing initialisation can be aborted at any time by pressing the hand symbol key. The previous settings are retained. All the parameters are reset to the factory setting only after performing a preset "55.PRST". Step J: If problems occur, carry out the measures as described in the table "Possible messages" shown in Figure 7. Step K: The initialisation is completed when "FINSH" appears in the bottom of the display. Step L: When pressing the hand symbol key briefly the menu item line "4.INITA" is displayed. Step M: To exit the configuration operating mode, press the hand symbol key for longer than 5 seconds. The software version is displayed after about 5 seconds. The instrument is in manual operation after releasing the key. Step N: The positioner can be changed to automatic mode by pressing the " j " key once as indicated in Figure 5. Step O: The automatic mode is the normal mode. In this mode the positioner compares the set point current with the current position and moves the actuator until the control deviation reaches the dead zone. Operation in the configuration mode

Service and maintenance The positioner is largely maintenance-free. The positioner is fitted with filters in the pneumatic connection as protection against coarse particles of dirt. If the pneumatic energy supply contains particles of dirt, the filters may be clog and impair the function of the positioner. In this case the filters can be cleaned as follows: Step A: Switch off the pneumatic power supply and remove the pipes. Step B: Unscrew the cover. Step C: Remove the three screws from the pneumatic connector strip. Step D: Remove the filters and O-rings behind the connector strip. Step E: Clean the filters (e.g. with compressed air). Step F: After cleaning first insert the filters in the recesses in the housing and then place the O-rings on the filters. Step G: Align the pneumatic connector strip on the two lugs and screw tight with the three self-tapping screws.

Note: Make sure that the same thread is used. To do this, turn the screws anticlockwise until they snap into the thread audibly. Only then should the screws be tightened.

The fluids must not contain any abrasive particles nor chemically attack the pump materials. Both pumps of the aggregate are designed asflange-mountedpumps and via pump bracket each connected with the driving motor. Attention: The aggregates are provided for horizontal installation or wall mounting. For safety purposes, the arrangement with ''motor downwards" is not admissible.

Structural design The screw pump twin aggregates of series SPZ consist of two screw pumps. Sectional drawings of the pump are shown in Figure 1 and Figure 2. The item numbers referred to in this section are those indicated on these drawings. Via a reversing valve casing (301), the two pumps are connected with each other. The screw pumps are of the three-screw type. A double-threaded driving spindle (12) and two double-threaded idler spindles (13) are enclosed by the bores in the pump casing insert (2) with a narrow running clearance. The pump casing (1) accommodates the pump casing insert (2) and is closed by the pump cover, drive side (3) and by the pump cover, non drive side (4) and thefiltercasing (9).

2.6 Pressure relief valve As an overload protection, a pressure-relief valve is installed in each pump, which is serially set to a response pressure approx. 10% above the operating pressure. 2.7 Non-return valves / stop valves In the reversing valve casing, a non-return valve and a stop valve are provided for each pump. The non-return valves operate automatically and can be locked by hand. 2.8 Operation control Manometers: • SPZ pump without filter: — Outlet side: a manometer (included in the scope of supply). If a mano/vacuum meter is requested on the suction side, this must be provided at the side. For connection, the bore for the screw plug (227) is provided. •

SPZ pump with filter:

— Suction side: two mano/vacuum-meters — Outlet side: one manometer Reversing unit: If a reversing unit was supplied for operation control, its circuitry is such that in case of failure of the operating pump the stand-by pump is automatically switched on. Signal lamps denote the respective operating conditions. Reversing unit Ul: for motors up to 3 kW (380 V operating voltage) for across-theline-starting. Reversing unit U3: for motors up to 3.0 and 5.5 kW (380 V operating voltage), suited for star delta-starting. 2.9 Oil trough The twin aggregate is provided with a separately supplied oil trough. 2.10 Drive / coupling Via the pump brackets flanged to the pumps, electric motors of the most varied designs are connected with the pumps. In the normal case, these are attached: Surface-cooled three-phase squirrel-cage induction motors, IMVl type of construction, enclosure IP 44 according it IEC Standard, class B insulation, performances and main dimensions according to DIN 42 677. Motors which are rated for 50 Hz can, without change, be operated also in 60 Hz mains, speed and performance are changed as shown in Table 2. Power transmission is effected via a flexible coupling. Additional radial forces must not act on the driving spindle. The pump brackets serve as protection against accidental contacts according to DIN 24 295. Attention: Drive via belt or gear wheel is not admissible.

Both screw pumps are jointly attached to the reversing valve casing (301). While one pump is in operation, the stand-by pump is at standstill. The pumps can be connected alternately by hand or automatically by means of a reversing unit (Ul or U3). By way of two separate connecting chambers in the reversing valve (301), the respective two suction flanges and the two pressure flanges of the two pumps are connected with one another. Uninterrupted delivery during the reversing process is thus ensured. During operation, the two lockable non-return valves (356) and the two stop valves (355) must be opened so that reversal is optionally possible from the one pump to

the other. The respective connected pump draws the fluid in through the suction chamber of the reversing valve casing (301). The operating pressure built up in the delivery chamber of the pump opens the non-return valve (356) of the operating pump and, through the pressure in the delivery chamber of the reversing valve casing (301), closes the non-return valve (356) of the non-operating pump. This prevents the stand-by pump from running in reverse motion. 3.2 Mode of operation of the screw pumps Through the suction chamber in the reversing valve casing, the material to be pumped is conveyed into the suction chamber of the pump in operation. From here, the fluid flows into the spindle chambers which are constantly formed by the rotary motion at the spindle end on the suction side. By the translatory rotary motion, the chambers filled with the fluid to be conveyed move from the suction side to the outlet side. During this process, the closed chamber volume does not change. At the spindle end on the outlet side the chamber opens towards the delivery chamber. The fluid conveyed is steadily pushed out into the delivery chamber from where it is transported, through the delivery chamber, into the pressure pipeline. The axial thrust acting on the faces of the profile flanks on the outlet side is hydraulically balanced by an appropriate dimensioning of the compensating piston of the driving spindle. Thus, the bearing is relieved from the hydraulic axial thrust. By appropriate dimensioning of the spindles, the drive of the idler spindles is hydraulic. Only the torque resulting from the liquid friction is transmitted via the profile flanks; therefore, they are practically stress-free and not subject to any wear. The axial thrust of the idler spindles is absorbed by the pump cover, non-drive side or by the filter casing. Sealing chamber and suction chamber are interconnected via a return bore. Therefore, irrespective of the delivery pressure, only the suction pressure acts on the shaft seal. All sliding parts are lubricated by the fluid to be pumped and are within the range of full liquid friction. In spite of spindle rotation, there is no turbulence. The constant chamber volume excludes squeezing. The structural design and the mode of operation of the screw pumps ensure a very low noise level and an almost pulsation-free delivery.

Preservation and storage of the pumps 4.1 Preservation If required, the screw pumps delivered by us are already provided with the requested preservation protection according to the storage time specified by the customer. Also in case of prolonged shutdown, the screw pumps must be protected against corrosion. In those cases, an outside and inside preservation is to be provided. The durability of the protection against corrosion which is limited in time, depends on the composition of the preservative to be applied. It is therefore recommended to use such preservatives only which have a minimum durability of 12 months. Below is listed preservative which can be applied for both outside and inside preservation.

4.1.1 Outside preservation All bright and unvarnished parts such as: shaft ends, couplings, flange facings, valve and manometer connections can be preserve with one of the following preservative: • TECTYL 506 • A mixture of TECTYL 506 and TECTYL 511-M1 This preservative is to be applied by painting or spraying with a spray gun. 4.1.2 Inside preservation Pump casing inside, screw spindles, ball bearing, pressure-relief valve, mechanical seal can be preserve with: • Mixture of: TECTYL 506 and TECTYL 511-M1 Note: The preservative listed above is to be regarded as a recommendation. Preservatives having the same preserving properties can also be used. The preservative is to be applied by filling the pump. For these purposes, the suction side of the pump must first be closed with a dummy flange. During filling, the pressure flange must be on a higher level than the suction flange. During the filling process, the driving spindle must be slowly cranked against the sense of rotation. Filling must be continued until the preservative reaches the sealing strip of the delivery flange, bubble-free. Thereafter, the outlet side is to be closed with a dummy flange. 4.1.3 Control of preservation In case of prolonged storage, the preservation of the pump must be checked by the customer at regular intervals. Step A: Every six months, the pump level must be checked, if necessary, preservative must be topped up to the sealing strip at the pressure flange. Step B: At the same time, the packing must be checked for destruction, and repaired, if necessary. Note: Liability for damages caused by improper preservation cannot be predicted. 4.1.4 Durability of the preservative According to the preservative manufacturer, the durability of TECTYL 506 is 4 to 5 years in case of indoor storage, and 12 to 24 months in case of outdoor storage, and of TECTYL 511-M approx. 18 months in case of indoor storage. When mixing TECTYL 506 and TECTYL 511-M in the same proportion, a durability of 254 to 4 years in case of indoor storage, and a maximum of 12 months in case of outdoor storage under roof can be expected. With additional packing, the service life is increased.

The active ingredients contained in this preservative provide sufficient protection against corrosion even in high air humidity (sea, tropical climate). Therefore, a temperature limitation (+ and -) does not exist. 4.1.5 Degreasing Prior to setting the screw pump in motion, the preservative applied must be removed. The preservative applied for inside preservation can normally be removed by flushing the pump with the fluid to be conveyed. In addition, a suitable solvent may be applied for removing the inside and outside preservation. Appropriate solvents can be: Petroleum, benzene, Diesel fuel, spirit, alkalis (industrial cleaners) or any other wax solvents. Steam jet cleaning devices with appropriate admixtures can also be used (allow wax solvent to react previously). Attention: Prior to start-up, the pump must befilledwith fluid to be conveyed so as to avoid seizing of the spindles during starting.

Note: If on the plant side, the pipelines, (oil) tanks and gear parts in circulation are wetted with the paraffin-containing preservative, the entire plant must be degreased as paraffin deteriorates the air separating capability of the (oil) filling. This may result in unsteady operation of the pump, connected with a loud noise development.

4.2 Storage During storage of the screw pump, the suction and outlet branches and all other supply and discharge branches must always be closed with dummy flanges or dummy plugs. Storage should be in a dust-free and dry room. Step A: During storage, the screw pump should be cranked at least once a week. Step B: During this process, the screw spindles should each time change their turning position. After prolonged storage, all elastomers (O-rings, mechanical seals) must be checked for their elasticity of shape. Step C: Embrittled elastomers must be exchanged. Note: Only proper storage and packing ensure the durability of the preservatives applied.

Foundation design/fastening type The foundation must be designed so that it can take the weight of the pump aggregate. Fastening is effected via the foot angle screw-connected to the intermediate lantern.

Mounting of the twin aggregate 6.1 Control of the sense of rotation at the driving motors The sense of motor rotation must correspond to the directional marker of the pumps. For a control of the sense of rotation, the motors may be alternately switched in temporarily in an uncoupled condition. The sense of rotation being wrong, the pumps do not prime. This will result in damages to the pumps. The sense of rotation of the respective three-phase motor can be changed by interchanging any two phases. 6.2 Installation of a complete twin aggregate A twin aggregate supplied complete was carefully assembled at the works. As the pumps and the driving motors are centred in the pump bracket, re-alignment of the couplings is normally not required. Note: Improper handling, for example, during transportation, may affect the alignment provided between pumps and motors. In this case, the respective motor must be dismounted from the pump bracket. Exact examination of the alignment is effected by means of a dial gauge with retaining clip and clamping device fixed to the driving spindle and motor shaft end. The examination covers the admissible circular and axial run-out between the shaft ends and the centring diameters and the plane faces at the pump brackets (0.05 mm admissible as a maximum). 6.3 Installation and assembly of pump and driving motor The aggregate being completed at the place of service only, the coupling must be assembled as follows: Step A: Cover pump and motor shaft ends with a filmy coat of molybdenum disulphide (e.g. Molykote), and insert keys. Step B: By means of a mounting device, push coupling halves onto pump and motor shaft end.

Attention: Axial shock loads on the driving spindle of the pumps and the antifriction bearings of the driving motors must be excluded during mounting of the couplings. Step C: Re-alignment of the couplings is not necessary (please refer to section 6.2).

6.4 Laying the pipelines 6.4.1 Nominal widths If possible, the nominal widths of the suction and outlet pipeline should be rated so that the rate of flow does not exceed 1 m/s in the suction line and 3 m/s in the pressure pipeline as a maximum. Note: The nominal diameter of the suction and pressure pipeline must be of the same size as the nominal pump diameter or one nominal diameter greater. The nominal diameter on the suction side must never be smaller than the nominal pump diameter, as suction may otherwise be difficult. 6.4.2 Change of cross-sections and directions Sudden changes of cross-sections and directions, as well as hairpin bends, must be avoided. 6.4.3 Supports andflangeconnections By way of the flange connections, the pipelines must be connected to the pump stress-free. They must be supported close to the pump and should allow easy screwing to avoid deformations. After the screws have been slackened, the flanges must neither be inclined nor springy nor rest on top of one another under pressure. Any thermal stresses that may occur at the pipelines must be kept away from the pump by taking appropriate measures, e.g. by the installation of compensators. 6.4.4 Cleaning of pipelines prior to attachment Prior to assembly, all pipeline parts and valves must be thoroughly cleaned. Especially in the case of welded pipelines, burrs and welding beads must be removed. Flange packing must not protrude inwards. Water residues, still in the pipeline network from pressing-out or steeping for example, must be removed. Delivery of water destroys the pump. The pump relies on the fluid being conveyed for its lubrication. At the pressure test of the pipe system the customer is responsible for any damages and their consequents. 6.4.5 Non-return valves / stop valves In the reversing valve casing, a non-return valve and a stop valve are provided for each pump.

INDUSTRIES

Note: With the non-return valve and stop valve closed, filter cleaning of those pumps may be effected which operate under supply pressure. 6.4.6 Venting The pumps withoutfiltercan be vented via the screw plug (227). In case of pumps with filter, the venting screw (223) in the filter and the screw plug (227) serve for venting. In addition, a vent valve must be provided at the highest point in the pressure pipeline. Note: In case of horizontal aggregate installation and with the suction and pressure flange turned sideways, the filling and venting bores and/or connections for the manometers must point upwards.

6.4.7 Filtering In case of aggregates which do not have filters attached at the factory, it is recommended to mount a filter in the suction pipeline to protect the pump against solid contamination. Filter mesh and/or gap size 0.1 to 0.5 mm depending upon the degree of contamination of thefluidto be pumped.

Preparation for start-up 7.1 Filling the pumps with the fluid to be conveyed

Attention: Prior to initial operation, the two pumps must be filled with the fluid to be conveyed. At the same time, the sealing required for suction is imparted to the spindles. The pump must not run dry. 7.1.1 Filling and venting of a pump without attached filter The withfluidto be pumped isfilledin through afillinghole at the suctionflangeof the pump. For these purposes: Step A: The screw plug (227) with the joint ring (156) must be removed. The pump must be topped up with the fluid to be pumped until this fluid emerges at the vent hole of the pressureflange,bubble-free. In case of supply pressure, manual topping-up is not required. The pump is topped up via the supply pipeline, and vented via thefillingand venting hole. 7.1.2 Filling and venting of a pump with attached filter Pumps in horizontal installation with attached filter are topped up via thefillinghole in the (filter) casing cover (7) until the fluid pumped emerges at the vent hole of the pressure flange, bubble-free.

For these purposes: Step A: The vent screw (223) and the screw plug (227) with the joint rings (143) and (156) must be removed. Pumps in vertical installation with attached filter are topped up with fluid to be pumped via the filling and vent holes in the casing as described under section 7.1.1. Note: Instead of the screw plugs (227), manometers may be mounted in the suction and pressure flange of the pump casing (1). Please refer to section 2.3.

7.2 Heating of the fluid to be pumped When pumping heavy fuel oils or other fluids to be pumped congealing when getting cold, it is necessary to provide a heating system in the plant (e.g. pipe steam trace). At the time of pump starting, the fluid to be pumped must be in a flowable and pumpable condition to avoid damages to the operating pump as well as the stand-by pump. Step A: Prior to the pump start-up, heavy fuel oil, for example, must be heated to at least 10°C above the solidifying point. Step B: For twin aggregates, with filters attached at the factory, a filter heating may be provided. A ring heater serves to heat the filter. The heating capacity of the ring heaters is designed so that with an initial temperature of 20°C, a minimum heating-up time of 120 min. is necessary. The temperatures being lower (below 0°C), an appropriately longer heating time must be expected. The heating system is not appropriate for achieving during operation a marked temperature increase of the fluid to be pumped. The ring heaters must be connected to 220 V (provide parallel connection, no series connection).

Start-up 8.1 Starting the operating pump Prior to starting the operating pump: Step A: The two stop valves on the suction side and the two lockable non-return valves on the outlet side of the reversing valve casing, and gate valves, if any, must be opened in the plant. A pressure-relief valve is installed in each pump which is serially set on our test field to a response pressure which is approx. 10% above the operating pressure. Step B: By means of the adjusting screw (333), the opening pressure can be changed within narrow bounds.

Attention: When starting and stopping the pump under pressure load, make sure that the speed and viscosity-dependent pressure load is not exceeded. If this is not ensued, the pump must be started at zero pressure or disconnected. This also applies to pumps with speedcontrolled driving motors. The pressure-relief valve must not be used for regulating the delivery flow. Step C: During starting, a vent valve on the outlet side of the plant must be opened until the air has escaped from the suction side of the pump. As soon as fluid to be pumped emerges, the vent valve may be closed. The pump is selfpriming and is automatically vented without counter-pressure. 8.2 Motor Step A: Switch motor of operating pump in.

8.3 Checking the delivery values Step A: After the motor has reached its operating speed, inlet pressure and outlet pressure of pump must be checked via vacuum gauge and manometer. The motor must not be overloaded. The power consumption can be checked by means of an ammeter. In this connection, temperature and viscosity of the fluid must be checked. The values read must be checked against the layout and/or acceptance report. Note: Pressure gauges such as vacuum gauges and manometers are normally equipped with stop valves. The stop valves are to be opened only during start-up for pressure control purposes. During permanent operation, these must be kept closed.

Stopping and restarting 9.1 Stopping 9.1.1 Motor Step A: Switch off motor of the operating pump. Attend to even and smooth slowing-down of the pump. 9.1.2 Reversing valve casing The non-return valves and stop valves in the reversing valve casing remain open.

9.2 Restarting After proper initial operation, the pumps are ready for operation at any time and can be started without filling. 9.3 Measures in case of prolonged interruption If a prolonged interruption is projected, the pumps must be drained as described below. Step A: The screw plug (222) must be removedfromthe draining bore. Draining of the filter is effected after loosening of the screw plug (235). Step B: Thereafter, the pumps must be preserved (please refer to section 4). Note: After the screw plug (222) has been turned out, the adjusting screw (333) of the pressure-relief valve must be turned out for drainage. Previously, by means of a depth gauge, the thread reach of the adjusting screw (333) in the pump casing (1) must be recorded. When screwing the adjusting screw (333) in again, this thread reach must be considered in order to reach the response pressure of the pressure-relief valve again (normally 10% above the operating pressure).

Control of operation and maintenance Regular control and maintenance works performed at the twin aggregate will extend the service life. The below-listed details apply in general. 10.1 General control •

The pumps must not run dry.

•

The driving motors must not be overloaded.

•

Check suction and pressure pipelines for tightness. The admission of air into the delivery system must be avoided.

•

The mechanical seal must not be heavily leaking.

•

Pressure and temperature monitoring instruments must be observed.

10.2 Control of components Item numbers mentioned in this section refer to the sectional drawings of the SPZ pump in Figure 1 and Figure 2. 10.2.1 Bearing and lubrication Bearing of the driving spindle of each pump is by means of a maintenance-free sliding bearing lubricated by the fluid pumped.

Language UK

Page 16/24

AALBORG

OIL PUMPS, TYPE SPZ

OM9295#02.2

INDUSTRIES

Under normal operating conditions, the service life of the sliding bearing corresponds to the lifetime of the screw pump. It depends on the degree of contamination of the fluid to be handled. 10.2.2 Check couplings At regular intervals, the couplings must be checked for wear. A worn-out coupling must be replaced. 10.2.3 Shaft seal Each pump is equipped with a maintenance-free mechanical seal of the unbalanced type whose mode of operation corresponds to the requested operating conditions. A minimum functional leakage in case of non-volatile fluids such as oils must in principle be expected. In case of heavy leakage due to wear, the mechanical seal must be replaced. Attention: As dry operation of the mechanical seal must be avoided, the pumps may be started in a filled and vented condition only.

10.2.4 Pressure-relief valve The pressure-relief valves of the two pumps must temporarily, especially after prolonged idle times, be checked for workability and function. Leaky pressure-relief valves may result in damages to the pump. If necessary, damaged parts must be exchanged or replaced. The pressure-relief valves of both pumps were set to the opening pressure requested by the customer (normally 10% above the operating pressure). If the opening pressure is to be changed then: Step A: The screw plug (222) in the pump cover, non-drive side (4) and/or in the filter casing (9) mustfirstbe removed. Thereafter, the adjusting screw (333) is accessible. Step B: Clockwise rotation increases, anti-clockwise rotation decreases the opening pressure. Re-adjustment should be effected with a perfect manometer only. 10.2.5 Filtering The twin aggregates of series SPZ...R..G8.3F have attached filters. The filter casing (9) is equipped with a mano/vacuum-meter (361) displaying the pressure behind the filter (481). The pressure loss suggests the degree of filter contamination. For an exact determination of the differential pressure, it is recommended to install a manometer in the front of each filter at the suction flange of the pumps or in the suction and/or supply pipeline. In case of noticeable differential pressure, thefilter(481) must be cleaned or replaced. Step A: Before the filter of a pump can be cleaned, it must be switched over to the stand-by pump. Thereafter, the lockable non-return valve (356) and the stop valve (355) of the pump at rest are to be closed.

Language UK

OIL PUMPS, TYPE SPZ

OM9295#02.2

INDUSTRIES

Step B: Filter cleaning is effected in that the filter (481) is removed from the filter casing (9), cleaned, and the dirt particles deposited at the filter casing bottom are flushed out. Step C: After the hexagon screws (207) have been slackened, the (filter) casing cover (7) can be removed and the filter (481) dismounted from the filter casing (9). Step D: Draining of the filter casing (9) is possible via the screw plug (235). For these purposes, use collecting tank. For cleaning and for dissolving any encrustations, the filter can be put into an appropriate tank and placed into a cleansing agent, however, the container may be submerged in the fluid only to the upper brim as otherwise, the dissolved dirt would get onto the clean side. Step E: After draining, blowfilteroff with compressed air from the clean side to the dirty side (from the inside to the outside, not the other way round!). Appropriate cleansing agents are benzene, benzine, Diesel fuel or a solvent-free cold cleaner. Other special cleansing agents may be used with the concentration depending on the kind and thickness of the dirt deposits to be removed. A soft brush may service as a cleansing tool. Do not use sharp objects. In case of excessive contamination, it is recommended to replace the filter (481) at certain intervals. StepF: After cleaning the filter (481) is loosely mounted on the pipe (30) in the filter casing bottom. Step G: The (filter) casing cover (7) isfixedto thefiltercasing (9) again. Note: The O-ring (119) must lie in its groove and not be damaged. Replace, if necessary. Step H: The (filter) casing cover (7) must be closed air tight, so that the pump may not draw in any air. Step I: The non-return valve (356) and the stop vale (355) are to be opened again. Step J: In case of supply pressure, the filter casing (9) must be vented via the screw plug (223) for re-starting the pump (please refer to section 9).

Operation Before proceeding with start-up of the heat-exchanger make sure that all connections to the heat-exchanger are securely tightened. Start-up of the heat-exchanger: Step A: Adjust the safety valve to the maximum design pressure. The safety valve can be set to a lower set point. Step B: Fill the heat-exchanger with oil. Step C: Ventilate the heat-exchanger. Make sure that the heat-exchanger and all connecting pipes are completely free of air. Step D: Remember to tighten the air ventilation plug after ventilation. Step E: Establish oil flow through the heat-exchanger.

Language UK

HEAT-EXCHANGER

OM8640#01.0

INDUSTRIES

Step F: Establish steam flow through the heat-exchanger. Step G: Operate the heater for approximately one hour. Step H: Stop the heat-exchanger by closing the steam inlet valve.

Note: When the heat-exchanger is stopped, it is very important to maintain the oil flow through the heat-exchanger for at least ten minutes in order to remove the accumulated energy in the heating elements. It is also important to make arrangements to ensure oil flow through the heatexchanger during emergency stops of the heat-exchanger. Step I: Stop the oil flow after ten minutes and tighten all screws again. To obtain the full output of the heat-exchanger, it must be supplied with dry saturated steam at the correct pressure. The steam pressure appears from the section "Technical data". It is important that the condensate system has a suitable outlay and that a correct type of steam trap is used to secure against the negative effect of counter pressure.

Maintenance and cleaning The heat-exchanger should be cleaned every six month and in the event of a drop in the output which is not related to other causes. Step A: Stop the heat-exchanger as mentioned above. Step B: Empty the heat-exchanger. Step C: Remove the tube insert. Step D: Check for deposits inside and outside the tube insert. Step E: The outside tube system should be cleaned by using a sharp liquid jet (use e.g. citric acid or water). Step F: The inside tube system should be cleaned by flushing the tubes with e.g. citric acid. Step G: If the heat-exchanger is heavily contaminated with carbon deposits, it is recommended to chemically clean the heat-exchanger with a carbon remover. Step H: The heat-exchanger must be flushed carefully with clean water and dried after the tubes have been cleaned. Step I: After the tube insert has been replaced, the bolts must be securely fastened and the heat-exchanger checked for leaks. Step J: Once every year the set point of the safety valve must be checked. Language UK

3.2 Dismantling and installation of the tube section The tube section is inserted into the heater and fastened tightly between the shell flange and the end flange. The back end of the tube section is free to move. The steam connections must be dismantled before dismantling the tube section for inspection, cleaning, etc. The tube flange has threaded holes for dismantling screws and for mounting eye bolts for lifting device. Packing surfaces should be cleaned and protected against damages. A new packing must be mounted every time the flange connection has been dismantled. When the flange connection is mounted again, all bolts should be tightened evenly and crosswise. A pressure test will show if the joint leaks. Operate the heat-exchanger for one hour, stop and tighten all screws.

3.3 Conservation during shut-down periods Corrosion which occurs in shut-down periods is mainly caused by oxygen. The corrosion appears where non-distilled or even slightly alkaline water has remained in the heat-exchanger. However, even when empty, the heat-exchanger is exposed to corrosion caused by water residues or condensation. For this reason an unused heatexchanger should be given an anti-corrosion treatment. In the event of prolonged off-cycle periods - in particular during winter time with frost - the heat-exchanger must be carefully emptied. Open the air valve and check for clogging.

3.4 Spare parts When spare parts are ordered, please state the serial No. (See the name plate of the heat-exchanger). For spare parts and further information please contact Aalborg Industries.
