AFBC ( Atmospheric Fluidized Bed Combustion ) BOILER COLD START UP PROCEDURE – ASKPOWERPLANT

Published on Oct View 3. Bed material Maximum Particle size Bulk density Chemical composition: Bed material to be filled and level of defluidised bed should be MM of WC.

Inspect the boiler before start procedurs check the following 1. Ensure the deaerator water level as normal. Ensure all access doors are closed. Ensure all personel were cleared. Ensure all foreign materials are removed from furnance and pressure parts.

Ensure all equipment trial to be taken. All interlocks to be cross checked.

Check the following equipments for adequate lubrication. Feed pump and drives. Fuel feeders and controllers. Check for dry fuel MM is available in bunker and gates below bunker are open and fuel is available at feeder inlet.

Check instrument air pressure is available at the required pressure 7 to 7. Check the following valves in boiler are in closed condition. Feed control valve and its bypass valve. Main steam stop and pilot valve.

Afbc Boiler Light Up Procedure

Drain valves of water level gauge. Check the following valves are kept in open condition.

Drum and main line vent. Valves before and after feed control valve in feed line.

Valves on feed line connecting to feed pumps operation. Start up vent valve.

Bed super heater drains. Check the bed material and fludisation study is being done. Set the air flow to MM of wc P. Measure air box pressure P1 MM of wc 3. Add gas plenum pressure P2 Furnace draught to P1. The pressure drop across bed is obtained for various air flow. The air flow at which fludisation starts is noted and will be maintained at the time of mixing.

Once fludisation study is completed boiler is ready for light up. Boiler light up procedure A fixed quantity of dry charcoal Kgs i. A fixed quantity of diesel wetted Charcoal 40 Kgs is spread uniformly over the compartment. Start the FD fan and maintain bed pressure mmwc. Start the LD oil pump and maintain the oil pressure between 6. Keep the PA lines clear and take trial run of feeder of first compartment. Light up all the four burners. Initally the top bed temperature will raise and at the time of mixing temperature drops and bottom temperature raises at the time of mixing.

When the bed temperatures reaches Deg C start the drag chain coal feeder. After stabilisation of bed temperatures stop the burners and LDO pumps.

Turn off the oil burners and remove from furnace. Close the bed superheater drains. Ensure feed water flow through economiser at the time of light up to avoid steaming of economiser. Maintain drum level at normal recommended level.

C and start the ash handling system.

C and stable the boiler.
