Hi,
Our Frame 6 GT# tripped on exhaust overtemperature during cold start at 33% TNH
This GT# firing starts at 20% TNH. I queried the operator whether he heard anything abnormal or vibration after firing & also whether the false start drain valve was working correctly, he confirmed that all were OK.
After reaching standstill, we carried out a check inside the turbine compartment & found nothing abnormal. We re-started the GT# and found everything OK, exhaust spread was as usual (around 10Deg C at 5MW) and (23 Deg C) at full load. The flow of fuel to each combustion liner was OK with same figures, as usual.
Existing control system is Mark V TMR.
Please advise
Regards,
Nizl
