We are having trouble during the start-up of our gas turbine (MS9001E) on liquid fuel. Whenever turbine reaches upto around 2900 ~ 2950 RPM, the VC3 valve starts hunting and within 5 seconds the machine gets trip over LOSS OF FLAME signal.
We have replaced VC3 servo valve, its hydraulic cylinder, checked and verified fuel oil accumulator's bladder pressure, fuel oil pump (PF1) working, Flow divider (88FD) discharge pressure. We are now also replacing VC3 valve, but we are still not sure that the problem will be solved or will remain stand still.
