Restart requirements
(OP)
On site we have a GE 9FA turbine. From AS BUILT manuals, GER 3620, there is a table for Turning. These are the generic operational guidelines for the time that the GT should be at turning after a shutdown or a trip and then restarted for normal operation. Verbally we also have been informed that GT can be restarted in less than 8 hours following a shut down if the wheelspace temperature is higher than 200 oC. Do you have any operation guidelines from GE on that issue? As you understand restart times are critical to avoid abnormalities on main GT parts but there is no automatic protection from MArk VI logic on that.





RE: Restart requirements
Depending on the unit configuration there are different maintenance factors and also there is a TIL that may apply.
Also is very important to know if the unit is in a single shaft combined cycle configuration with a steam turbine directly coupled or not.
To clarify your question more data are required.
