Dear Members,
I am working in GE 7FA.05 Dual fuel gas turbine and we are using as a fuels natural gas (NG) & Arabian super light crude oil(ASL).
One day GT started by natural gas with ASL crude oil recirculation condition, when GT reached FSNL and after 5 min GT speed reduced to 95% speed, that time responsible person select Liquid fuel page and ''LIQUID FUEL RECIRCULATION/CONTROL CONNECT'' mimic ENABLE button select. But GT speed not raised to above 95% of speed. So he raised speed by manually and synchronized.
My question what is the relationship between GT speed and Liquid fuel recirculation line pressure and flow during gas fuel start up?
