we have two GT that after two years working liners are deformed and nozzles head are melted very bad.
why our gt has damaged so bad?
five months before gt breakdown it could not go to premxed mode and it was working in lean lean mode with 100mw load and we could not be able to turn it off and fix the problem. because of the situation.
it was working until the last day that an alarm occurred: (uv flame detection alarm) and the operator does not pay attention he thinks it is because of chamber flame detectors. after some hours GT tripped with gas detectors alarm and we see that two flexibles are disconnected and melted. the transition manifold flange is melted too. and after we opened the chambers we saw all liners are vacuumed in and transition nozzles head part are melted.
another alarm there was low purge pressure, with 2 or 1.9 bar pressure. and it was working more than 1 month then we could turn off gt and fix the problem. in the last five months gt was working with more than 3 bar pressure.
