My machine is SIEMENS Gas turbine V94.3A (Dry Low Nox Combustor) which operate by natural gas. The gas turbine use premix flame as main fuel and use pilot flame for increase the flame stability and i found the problem as follows:
I found high combustor acceleration value around 2.5 - 3 g. when GT is loading or unloading at % IGV opening around 20-30% and this problem will run away when GT is operate out of %IGV range 20-30%.
How to solve this problem.
Thank alot for any help.
