Hi,
We have a frame 9E Gas Turbine with Mark VI control.
What is the Logic of Turbine Compartment Vent fans during shutdown and Trip? As far as manual is concerned it mentions that both fans should trip at flame out and restart after one hour and remain running until the wheelspace reaches 300 F. But I have checked the m6b and past trends which state otherwise and the fan continues to run after flame out, until the wheelspace condition is met. This is probably causing rapid cooling of the turbine.
Can anyone Please advise regarding this scenario. I can share more details if required.
