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 1/3rd to 3/4th 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.

  • 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 3/4th 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
