Dear Sir,
Our plant configuration is two blocks. Each block consists two 9fa Gas turbines and one GE D-11 steam turbine. we are facing the problem with one block steam turbine whose corrected output is around 3 to 5 mw less than other steam turbine. we have come up with some observations like condenser pressure variation with other steamturbine is around 0.030 bar. and High pressure steam header flow is around 20 ton/hr less than other steam turbine. Other than this we felt all other parameters seems same for both steam turbines.
what can be the possible reasons for reduced steam turbine power output? I mean can you please suggest what are the main factors influencing steam turbine power output. and also suggest me the best way to troubleshoot. so that i can come up with solution. please guide me how to troubleshoot and what parameters i must be mainly looking. so that i can make trends for various parameters. almost we are running both blocks on same load I mean all GT's are at same load.
