what is the abrivation of GE- 9FA and 9E gas turbines

Answer Posted / bhola shanker

9E turbines have cranking motor,  no lift oil for turbine bearings,  having additional bearing near the marriage coupling I.e.,in between compressor sand turbine, because of lower capacity the generator is air cooled, 
Whereas 9FA turbine have LCI for cranking, have lift oil for turbine bearings, unlike 9E is having only bearing only at the extreme end of the compressor and turbine and generator is hydrogen cooled. 

Is This Answer Correct ?    2 Yes 1 No
