Steam Turbine Start-Up Procedures

Steam Turbine Startup Procedures

Steam turbines are essential in power applications — they power main and auxiliary machines, running pumps, fans, generators, and more. Operators must follow steam turbine operating procedures to ensure the plant operates as expected and doesn’t experience thermal or mechanical stress.

Steps in a Standard Operating Procedure of a Steam Turbine

Once the starting prerequisite steps are complete, operators can begin the startup procedure for its steam turbines. Very generally, the procedure may include these steps:

Check the turbine oil sump level. Drain any water and replenish levels if needed.
Start the lube oil pump, check the oil pressure, and set the oil pumps to auto.
Make sure the water tank of the condenser vacuum pump is at a normal level.
Check the condenser condensate level and put the condensate pump on auto.
Start the vacuum pump.
Open the cooling water valves for the lube oil cooler and vacuum pump cooler.
Drain condensed water from the steam line in the steam drain valve.
Open the main steam inlet valve to the turbine.
Verify gland steam pressure is normal.
Verify lube oil pressure, steam inlet pressure, gland steam pressure, and condenser vacuum are normal.
Roll the turbine to warm and close the steam line drains.
Check the first- and second-stage steam pressure.
Check the condenser water level and vacuum.
Bring the turbine to speed.
Check the vibration and lube oil pressure.
Check parameters like the condenser level, vacuum, generator frequency, voltage, and speed.
Give control to the remote station and place the generator online.
