Feed system safety concept



1.



1.1. Notes on design



Feed system safety concept As a general rule, the feed system is installed under pulverized coal bins equipped with devices to reduce the explosion pressure to 3 bars or designed explosion-pressure-proof to 10 bar. On the following pages, the safety concept of the MULTICOR®-K feed system for pulverized coal is described with examples.



1.1. Notes on design n



The electrical and mechanical equipment is designed for use in Category II 2D, or 3D in accordance with EN 13463 (ATEX directive). Strictly observe the order-specific documentation. –

Type MC 640 / .. MC 800 / .. MC1000 / 100 MC 1000 / 65 MC S40-d MC S160-d MC K40 MC K50/80 MC K120/180



Designed with sufficient power reserve, the system’s drive motors stay comfortably below the specified glow and ignition temperatures of pulverized coal under normal operating conditions. In case of fault, drive motors are cut off by thermal overcurrent circuit breakers, integrated temperature sensors, or frequency converter. Motors are protected at least to IP54.



This unit is built to be 10 or 16 bar explosion pressure shock proof in keeping with sheet 3 of VDI guideline VDI2263. MULTICELL is designed explosion-pressure-proof and flameproof in accordance with guideline VDI2263, Part 3, and has been tested and certified by an independent office. Depending on type, the following safety characteristics result:



Explosion-pressure-proof *1) to max. explosion overpressure 16 bar 16 bar 16 bar 10 bar 10 bar 10 bar 10 bar 16 bar 16 bar

If dust explodes inside the components attached to MULTICELL in the amount of the above stated pressures, the explosion cannot propagate via MULTICELL in specified direction. Therefore, MULTICELL as a flameproof locking device can normally be used to protect the pneumatic conveyor pipe when dust explodes in the storage silo. All data apply to dusts of explosion class St 1 (pulverized coal max. 200 bar m/s) in normal atmospheres. If dust explodes, damage to the movable parts inside the machine cannot be excluded. Therefore, the system should be checked after the event in order to ensure peak functionality and safe operation. The flameproof design of the rotary feeder protects the pneumatic conveyor pipe. In addition, smouldering material should be detected early and prevented from entering into the conveyor pipe by protective measures (e.g. inerting). MULTICELL and MULTICOR-K are designed to withstand this incident without damage for a certain period of time. However, the ATEX regulations do not allow ignition sources to pass through the devices while an explosive atmosphere is present inside. Please see the instructions given at Item 3.6, page 19. The device volumes have been kept intentionally small, in order to keep the explosion hazard down if the dust concentration inside the device is permanently high (partially Dust-Ex Zone 20). Under rated operating conditions, the system components neither produce sparks nor increased temperatures that have the potential to ignite. The systems are designed so that no ignition source is activated, not even in the rare case of fault, provided that they are properly installed and maintained (very high degree of safety). Static electricity is arrested by appropriate protective earthing.



The system configurations depicted at Items 1.2 to 1.6 are sample solutions. As a rule, the dimensioned drawings and planning documentation supplied on your order apply.

1.2. MULTICOR-K with MULTICELL



1.2. MULTICOR-K with MULTICELL This design is used in areas which are under the pressure of the pneumatic pulverized coal conveyor to the burner.



Fig. 1: MULTICOR-K with MULTICELL



In the basic design, the forces resulting from the conveying pressure, its pressure variations and the silo displacement fy (displacement caused by difference between empty and full weight of silo) are absorbed by a compensator. (fy = please find this value in the order documentation). A pressure compensation as shown in the figure may be supplied as an option. In this case, the forces will not affect the measuring accuracy of the silo weight measuring device.

1.2. MULTICOR-K with MULTICELL



Feed system safety concept



The MULTICELL unit feeds the pulverized coal speed-controlled into the MULTICOR unit. The mass flow of the pulverized coal is supported by a stainless steel lining and ventilation nozzles in the silo outlet area. The stainless steel coating must reach to half the cone height, at least to a ∅ of 3 m at a wall inclination of ≤20° against the vertical. For more information, see manual BVR2128.

1.3. MULTICOR-S40-d and -S160-d with MULTICELL



1.3. MULTICOR-S40-d and -S160-d with MULTICELL The design MULTICOR-K160/ -S...-d is used for pulverized coal feeding in unpressurized areas, i. e. in areas under atmospheric pressure, e. g. upstream of pulverized coal pumps.



Fig. 2: MULTICOR-S40-d / -S160-d with MULTICELL



The return air of the pulverized coal pump is lead into the atmosphere as pure air via a pressure filter on the pump extension hopper. For this reason, the air pressure variation at the MULTICOR-K outlet may not exceed the filter pressure difference specified in the drawing. Thus, air pressure variations cannot affect the measuring accuracy of MULTICOR-K160 / -S-d- nor that of the silo weight measuring device. An admissible silo displacement fy, which may be caused by the difference between the full silo weight and the empty silo weight, is compensated by a compensator. The compensator can also

compensate silo displacements up to 30mm, in this case, however, measuring errors by the silo weight measuring device may arise. (fy = please find this value in the order documentation). The starfeeder - in the drawing type MULTICELL - feeds the pulverized coal speed-controlled to the MULTICOR unit. The mass flow of the pulverized coal is supported by a stainless steel lining and ventilation nozzles in the silo outlet area. The stainless steel coating must reach to half the cone height, at least to a ∅ of 3 m at a wall inclination of ≤20° against the vertical. For more information, see manual BVR2128. Instead of the MULTICELL unit, it is also possible to use an appropriate feed screw with explosion-pressure-proof design.

Fig. 3: MULTICOR-K with silo discharge agitator



In the basic version, the forces resulting from the conveying pressure, its pressure variations and the silo displacement fy (caused by the difference between full and empty silo weight) are absorbed by a compensator. (fy = please find this value in the order documentation). A pressure compensator as shown in the drawing may be supplied as an option. In this case, the forces will not affect the measuring accuracy of the silo weight measuring device.

The silo discharge agitator transports the pulverized coal into the pipeline to the MULTICELL unit. This unit feeds the pulverized coal speed-controlled into the MULTICOR unit. The mass flow of the pulverized coal is supported by a stainless steel lining and ventilation nozzles in the silo outlet area. The stainless steel coating must reach to half the cone height, at least to a ∅ of 3 m at a wall inclination of ≤20° against the vertical. The required number of ventilation nozzles is determined for each individual order in accordance with the flow properties of the pulverized coal. For more information, see manual BVR2128.

1.5. MULTICOR-K with MULTIFLOW



1.5. MULTICOR-K with MULTIFLOW MULTIFLOW is also used in the silo agitator described in Chapter 1.4. A positive characteristic is the fact that there are no more moving parts in this silo output. The design surfaces and angle of inclination guarantees the discharge characteristics needed.

1.6. MULTICOR-K with a pipe calibrator



Feed system safety concept



1.6. MULTICOR-K with a pipe calibrator A check bin is inserted between the storage bin and starfeeder (pipe calibrator). It may be designed cylindrically or comically as shown The pipe calibrator is used to feed a certain control amount in the same fashion as a loss-in-weight feeder without interrupting actual feeding into the pneumatic conveyor line. Weighing result is used for calibrating MULTICOR K. The bin has to be decoupled from the silo weighing mechanism. This is done with an automatically operated working valve and a properly arranged flexible connection. The check bin can be impinged at a maximum conveying pressure of 450 mbar during the control measurement (pressure compensation) to facilitate continuous discharge. If the silo has pressure relief equipment, the pipe calibrator and the silo are sufficiently dimensioned for 3 bar. If the silo is not dimensioned for a pressure shock resistance of 10 bar without pressure relief, the pipe calibrator and its add-on parts should also be dimensioned at the same strength.

Feed system safety concept



1.6. MULTICOR-K with a pipe calibrator



The pressure-relief system does not function during the control measurement because the working valve is closed. The pressure shock resistance of 10 bar that can be generated now is not sufficient when using the pressure compensation line. Therefore, all sources of ignition in the form of smolder spots in the pipe calibrator should be eliminated during the control measurement or they should not be allowed to cause any problems. This is the reason why this configuration should always be operated with a CO monitoring system for the silo. Weighing electronics should be used for locking the working valve with the CO monitoring system so that the valve stays open if there is a CO alarm or opens immediately interrupting the control measurement. If the silo does not have any CO monitoring system, the pipe calibrator should always be inertised when the valve is closed. The working valve is always open if MULTICOR K40 is in continual feeding operation as in most cases. This situation is identical to standard feeding as found in Chapter 1.2.

The air supporting of the MULTICOR-K40 unit always has to be supplied with air during plant shutdown. The compressed air supply may only be disconnected when the manual silo valve has been closed – dbefore plant shutdown – MULTICELL and MULTICOR-K40 have been run empty without any deposits of pulverized coal and – the conveyor route of the feed system has been depressurized, meaning it is under atmospheric pressure (there is not any furnace back air). In addition, the conveyor line has to be locked against back air and flashback by a shut-off device directly in front of the furnace. The air supply for the MULTICOR-K50, 80, 120 and 180 models can be turned off during plant shutdown. Always shut down the drive motor of MULTICOR-K and the starfeeder in advance. Do what is done with MULTICOR-K40 if the feeding lane is shut down permanently or for a longer period of time. If specific units are turned off and the conveying pressure is on, the air supply of the units has to stay turned on with several MULTICOK-K (all models) feeding into one conveyor line unless there is a ball cock that is shut off between MULTICOR-K units and the conveyor line. MULTICOR-K should only be turned on with properly set smooth start switching to protect the measuring gearbox.



The scope of delivery can include the discharge systems, pipe calibrator and hopper where residues of non-flowing material might remain in the system if one or several systems are turned off. The operator should take this situation into consideration when laying out his plant safety strategy for spontaneous combustion. The orders described in Chapters 1.2-1.6 can also be combined. Special safety instructions for a specific arrangement also apply to a combination.

2.1. System assembly and start-up We recommend that you only have the system assembled and/or started up by skilled personnel to ensure proper functioning and safety. If the system is improperly assembled and/or started up, Schenck Process reserves itself itself the right to restrict or totally reject Schenck Process’s warranty.



2.2. Qualification of personnel Only qualified, trained personnel which has been instructed correspondingly may carry out the maintenance work described in the operating manuals. n The qualified personnel must be familiar with locksmith*s work and safety-conscious handling of parts with the crane. n CAUTION IN CASE OF WELDING WORK!! – Installation welding on explosion-pressure-proof components may only be carried out by qualified welders, – the quality of the weld seams is to be assured in accordance with DIN EN 25 817/09.92, group C (mean), – To protect the load cell, connect the negative pole directly to the welding point. n Measurement work may only be performed by qualified measurement and control engineers. n The qualified personnel must be familiar with the local safety and accident prevention rules and observe them. n Welding work may be performed only if no dust explosive atmosphere is present.

Only trained and instructed personnel may operate the feed system in accordance with the following instructions. Since the feed system forms part of an overall system (plant), the operator is obliged to add such instructions to these operating instructions which are valid for the entire system, and to make them available to the operating personnel. The operating personnel must be familiar with the in-house safety and accident prevention rules of the company and observe them. The operator should be aware of the potential consequences of manual changes made in feed operation if there is a local operating point on MULTICOR K. This especially applies to starting feed operation and changing the feed rate that under certain circumstances might cause critical operating states. This is the reason why it may only be locally operated if the manual valve is closed and the starfeeder is completely emptied.

After a pulverized coal explosion or after a fire in the area of the feed system or after smoulder spots have been passed through the feed system, all units of the feed system must be subjected to a checking procedure in accordance with the corresponding notes and instructions in their manuals. As a general rule, flexible connection pieces and compensators are to be replaced.

2.5. Use In The Hazardous Area



2.5. Use In The Hazardous Area Talking about potentially explosive atmospheres, we distinguish between Gas-Ex and Dust-Ex zones. The Schenck bulk solids feed systems are designed order-specifically for operation in the Dust-Ex zone where a potentially explosive atmosphere is present seldom or occasionally (Zone 22, or 21 - ATEX 118). When using your feed system, observe the legal regulations and standards, e.g. never unplug electrical equipment under voltage, never clean conductive plastic parts using dry cloth. The operators, particularly maintenance men, must be aware of the regulations valid for the hazardous zone. The feed system may be operated only in Ex zones approved for the system in question. Strictly observe the instructions given in relevant Ex manuals.

Your MULTICOR feed system is designed for measuring the feed rate of pulverized coal in accordance with the Coriolis measuring principle. The feed system must be operated in keeping with the order-specific TECHNICAL DATA, which form part of the operating instructions. During commissioning, the feed system with the electronic evaluation system must be calibrated for the order-specific material in accordance with the TECHNICAL DATA of the system. For safety reasons, the feed system must not go into operation until it has been installed into an enclosed conveyor route in keeping with the order-specific INSTALLATION MANUAL. If the customer*s process and pulverized coal data deviate from the order-specific TECHNICAL DATA, we would strongly recommend to consult Schenck Process in order to avoid damage. The feed system is not appropriate for passing – tramps with edge measure ≥35 mm and – threads, e.g. angle hair – justs with a minimum ignition energy < 3 mJ. For safety reasons, no ignition source (e.g. smouldering material) must enter into the system offhand. Observe the instructions given at Item 3.6, page 19. The feed system operates hermetically sealed. To avoid pulverized coal leakage and the loss of explosion-pressure resistance , the screws, in particular at the flanged connections, must never be loose. The screws must be tightened with the specified tightening torque. Any pulverized coal leakage at the shaft leadthroughs of the silo discharge agitator , MULTICELL , feed screw and / or vertical starfeeder must be remedied without delay to prevent spontaneous ignition. Maintenance work must always be carried out during standstill of the unit in accordance with the operating and revision manuals of the units. CAUTION!! Important operating note: The service life of the air bearing for the measuring wheel shaft in MULTICOR-K units largely depends on the permanent availability of compressed air. Therefore, the compressed air supply must always be ensured, even during a standstill in the process, by appropriate measures.

3.2. Silo discharge pulse ventilation (with Simplex only)



3.2. Silo discharge pulse ventilation (with Simplex only) The silo discharge pulse ventilation implemented in accordance with the planning documentation supports the necessary mass flow of the pulverized coal in the area of the silo cone. It is based on circular lines supplying compressed air to the ventilation nozzles. The air supply is pulsed through solenoid valves. The pulse to interpulse period ratio is to be entered in the electronic evaluation system. The nozzle-valve unit shown in the drawing below demonstrates the function of the outcoming air (in direction of arrow) below the rubber cap. CAUTION! n



n



Never set the compressed-air service unit to a pressure > 2 bars, since this could cause the rubber caps to fall from the nozzles, and, as a consequence, the function of the solenoid valve would be impeded by pulverized coal. The customer must ensure that, in the event of a CO alarm, the compressed air is automatically switched to silo inerting.

3.3. Smooth-start control of MULTICOR-K, S160-d As a general rule, before the MULTICOR-K is commissioned for the first time by instructed measuring and control engineers, the smooth-start control system in the control cabinet must be set to the following values while the power supply is switched on : n Set start time tE to maximum value. n Set start voltage (phase - phase) via potentiometer “starting torque” ME to 0.7 times the nominal motor voltage and measure it with the moving coil instrument. Check whether the measuring motor slowly starts accelerating at this voltage after switch-on. n Disconnect motor and set start time to approx. 5 s. Check with the help of light-emitting diodes. n Set deceleration torque MA and deceleration time tA to their respective minimum values.
