Sop for operation of boiler.

I. Purpose & Scope:

• The Purpose of this SOP is to lay down the procedure for operation of boiler.
• This procedure is applicable for operation of boiler used in engineering Department

II. Responsibilities:

• All Engineering personnel’s shall be responsible to follow and implement this SOP.

III : Introduction and Procedural Part :

Precautions :

• Ensure three phase power supply should be available in panel.
• Water should be available at least half in storage tank.
• Water level should be maintained between 1/3^rd to 3/4^th boiler chamber.
• Furnace oil should be available in day tank.

Operation of boiler Procedure :

• Check the oil in FO storage tank, maintain the level above outlet line.
• Transfer the FO through transfer pump from storage tank to service tank.
• Maintain the temperature of service tank 110°C to 130°C.
• Open the valve before and after ring man pump.
• Check the water level in boiler gauge glass, select any of two water feed pump in auto mode.
• Maintain the water level ¾ in gauge glass.
• Stop water feed pump and close inlet valve.
• Open all valve before and after fuel feed pump.
• Start the fuel feed pump and maintain the pressure inlet 3-4 kg/cm², outlet 18-21 kg/cm².
• Switch on the pre heater and maintain the temperature between 110 °C to 130°C.
• Switch on the blower.
• Switch on the burner in auto mode.
• Burner will fire automatically. If not switch off the burner and check the reason.
• In case of sequence controller not functioning in auto mode, till rectification of sequence controller, burner can be fired in manual mode.
• Push the ignition push button and turn the burner switch in manual mode. Burner will fire then release the ignition push button.
• If not fired within 30 seconds stop the burner, check the ignition transformer, sparking electrode, photo cell and burner nozzle.
• Open the water feed pump inlet valve and select anyone water feed pump in auto mode.
• Raise the pressure up to 6 kg/cm².
• Open all condensate bypass valve.
• Open the steam main valve slowly.
• Allow condensate to drain out completely.
• Close the condensate bypass valve, open the trap valves and ensure steam trap functioning.
• Maintain the water level between 3/4^th in gauge glass during running the boiler.
• If there is black smoke in chimney, increase the blower air by opening of damper.
• If there is white smoke in chimney, decrease the blower air by closing of damper.
• Record the activity details in Boiler Log book

Frequency :

As when required

Stopping Procedure :

• Switch off the burner.
• Switch off the blower.
• Switch off the pre heater.
• Switch off the fuel pump.
• Release the steam by opening the vent valve.
• Maintain the water level ¾ in boiler gauge glass.
• Switch off the water feed pump.
• Close the suction valve of the feed pump.
