We operate a frame 6B gas turbine at AES Nig. Currently we are having a combustion problem in one of our units. At about 20-25Mw load target, bursts of pulsations are heard with the PCD dipping well below FSNL value even at operating speed. Meanwhile, the load value takes big jump upwards. The exhaust average skyrockets and the unit trips. We are wondering what could be happening. Any help please?

And read on down from there.

It is suggested that site have someone knowledgeable come to witness and investigate the problems.

Please write back to let us know what the resolution is.
