In one of Gas Turbine (Frame 6B) running on Liquid Fuel load is not increasing beyond 25 MW. In gas same machine was giving 30 MW. Up to 24 MW, FSR is in control. As soon as we increase preselect load to 25 MW, FSR starts increasing but MW does not increase even with FSR increase to max limit.
We have checked Liquid fuel system for choking, Liquid fuel bypass valve calibration etc.
Now what is left is changing with new LFBV and new liquid fuel pump.
Can there be any other cause for this?
