  • Suction valve in open condition and ensure priming of pump by opening of vent valve.
  • Re circulation valve, leak of balancing valve are in open condition.
  • Discharge valve is in closed condition
  • All pressure and temperature gauges are in line
  • Oil level in oil tank above 70% level
  • Ensure cooling water is in line for pump bearing and mechanical seal

Start AOP

(control oil pressure should be operating pressure).

  • AOP discharge oil pressure should be according to SOP (Standard Operating Procedure).
  • Oil pressure at motor bearing should be according to SOP (Standard Operating Procedure).
  • Ensure oil flow is view glass at pump bearings.

Start HP Pump

Check following

  • Pump suction pressure should be according to SOP (Standard Operating Procedure).
  • balancing line pressure should be according to SOP (Standard Operating Procedure).
  • Auto cut of AOP after taking over of load by mop
  • Motor current with respect to recirculation load
  • Any abnormal sound from pump and motor
  • Bearing temperature of pump and motor should be according to SOP (Standard Operating Procedure).
  • If everything is okay, then gradually open pump discharge valve and check motor current with respect to load
  • Check for any abnormal sound for pump and motor

Start BFP turbine (Boiler Feed Pump Startup Procedure)

  • After start AOP and checking all oil pressure, engage trip lever by lifting knob.
  • Reset solenoid valve throw control panel
  • Open cooling water inlet and outlet valve
  • Open all range of steam line
  • Open inlet exhaust steam isolation valve
  • Start opening Governor manually till the turbine is start rolling
  • Accelerate speed of turbine by opening its governing valve and bring up to operating speed
