    Impact of high HHV on GE 9E performance

    I'm working with a gas turbine of GE-9E, equipped with WLN burner and duel fuel capability, currently running on natural gas. Sometimes we experience higher quality of gas from the gas grid. Say, HHV 1045 BTU/SCF raises up to 1100 BTU/SCF. Should there be any performance degradation? Or...

    Natural Gas Chromatograph value error

    For some days, we have been facing unusual Gas Quality fluctuation. Methane showed almost 100% from 92%, Ethane showed almost 0% from 7%, and HHV & LHV also unusually decreased. GC recalibrated multiple times. But still issue persists. Can anybody explain? Which way to check? Thanks in advance.

    Capacity of Gas Turbine on different types fuel

    I got the answer to my 1st question. Secondly, let me mention some operating conditions and other parameters for your understanding. 1. Our machine 9E.03 mostly runs in FGMO (Free Governor Mode of Operation), in that case, we're not getting stabilized internal temperature. I understand. a...

    Capacity of Gas Turbine on different types fuel

    Thanks for your reply WTF? Yes, I know the heating value facts of different fuels. I have one more specific question. Is it practical to get the same heat rate considering same ambient conditions, same fuel type (say, gas), same load setpoint, but different HHV of gas. I've found the gas...

    Capacity of Gas Turbine on different types fuel

    Is it usual to have a generation Capacity on Natural Gas (95% Methane) is little bit greater than Capacity on Liquid Fuel (Diesel) of a typical Gas Turbine (Especially GE 9E)? If so, can somebody explain why?
