Hi all,
Need your expertise explanation out there for the above matter. I have a GE 9FA single shaft unit, during previous days, when compressor blades fouled, our CTDA or compressor discharge temperature will be at 426'C and CPD will be at 13.9barg during BASELOAD. while cleaned compressor blades (after offline wash) will shows around 398'C, CPD around 14.4barg. Lately this year, I observed that although compressor blades fouled - CPD at 14.0 barg and alarm backup temp curve active, the CTDA only at 410'C only. Can anyone experienced this problem before? Any related with air leakage from compressor?
