Exhaust from SGT6 5000F turbines

Exhaust from SGT6 5000F turbines

Im having problems with my GT exhaust turbine because of combined cycle, we have had insulation detachment and it is a several problem since we have to shut down and repair my damper. I need information about the possible root...

RE: Exhaust from SGT6 5000F turbines

I'd guess that it's gettin' too hot for whatever is attachin' the insulation.
So the insulation falls off, and what? ... fouls your damper?
Find a better way to attach the insulation, or make your damper more resistant to fouling by insulation.

If you need further information about the root, you need to give more information about the problem.

We have found insulation from Diverter Dumper breaks off, im talking about the liners (plates)... I think diverter's movement because of HRSG trips could be a problem?... plates detachment was found only at the front of the diverter ( not exhaust walls)

RE: Exhaust from SGT6 5000F turbines

Have you considered differential expansion of the various metal parts of the diverter damper? Is it at uniform tmeperature, or is there a rapid transition upon a trip?

Are you burning gas fuel or liquid fuel?
Liquid fuel will break your heart...

How old (hours/starts) is the thing? Is this a base loaded or cyclic operation? Exhaust systems are very sensitive to cyclic operation.

Liquid fuel will break your bank.

We are operating in combined cycle since April 2012, we use natural gas as fuel and we are on cyclic operation ... there are a rapid transition upon a trip... Is it something normal? I'd like to know about your experiences.
