Hello,
Our gas turbine is GE MS9371 9FB.
Until today we have applied turning gear natural cooldown operation without force cooling. But especially in maintenance periods, I need rapid cooling methods/application via selecting crank speed with LCI to accelerate turning gear shutdown process. In natural cooling, following shutdown, when wheelspace temperature is less than 150 F, turning gear is being off after around 60 hours via, and this natural cooling causes waste of time.
GER3620 is giving general information for us but it is not adequate.
Do you have any application or operation methods for this topic?
