We have two 9E dual fuel gas turbines.Both the machines were in standstill condition for 12 to 14 hours and maximum wheelspace temperature were 33 degC for each machine before going to standstill. We made the Turning System of both GT normal and put them into turning after 14hours. But GE T/A here at our site advised both machines must be four hours on Turning before start. Can anyone please help me regarding this issue?
I have the experience with Siemens V94.2 & MHI701F. In case of Siemens V94.2 we can start the machine after one or two hour turning and in case of MHI701F we can start the machine two/three hours turning.
