Dear CSA,
We have gas turbine frame 9. E
Fuel is light crude oil.
Our problem is during normal shutdowns and after the generator breaker opened and RPM is going down sometimes when the speed reaches 1600-1700 RPM, an alarm comes ( turbine trip by loss of flame ), as happened in the last two normal shutdowns not as before the flame had gone at 1200-1300 RPMS . And sometime normal shutdown is going smoothly.
please, could you help us.
Regards.
