That you vikneswaran?

Sounds like you broke it. Fleam off alarm, no idea (flame off perhaps?).

You had better contact Alstom or their service agent. Don't try and operate the unit or bypass the safety alarms otherwise............BOOM (potentially).

Should not have tried the 120MW. Apparently it did not like that sudden change.

Is th turbine even made for this?

Close the valve earlier or later maybe - oh hold on - no don't use it at all.

Call the manufacturer support.

Dont get killed.

Why don't you quit wasting your time trying to get it fixed for free and call the tech service people at Alstrom!! (860) 688-1911.

You DO have a telephone, don't you?

The HP bleed valve is there to reduce the compressor load during startup, and closing it affects the air/fuel ratio. You're getting a flameout because the extra load (and air) from the compressor is not being compensated for with additional fuel, too much air/not enough fuel and the flame cools/gets blown out. You need somebody on-site that understands the fuel management system and how to tune it, this is not a job for amateurs, as others have said...Call the factory...now. The job you save may be your own.

Maby it will just disassemble itself explosively.

You need to talk to Alstom or their agent and get professional help. A faulty 120MW gas turbine is not something we are comfortable at guessing at and neither should you be.

42 is "the answer to life, the universe and everything". To understand this joke, you need to have a passing acquaintence with " The Hitchhiker's Guide to the Galaxy", which is available at all good booksellers, and possibly on-line for book reader tablet computers.
