In this study, we have investigated the effect of the fuel on the performance of industrial gas turbines. It is intended for both fuels. First fuel as the main fuel is natural gas and second fuel is synthetic gas.
Synthetic gas fuel heating value is less than the primary fuel for gas turbines. Therefore, to achieve maximum thermal capacity of the turbine should increase the fuel flow rate. Increasing the fuel flow rate, cause gas turbines are excluded from the On-design point. To determine the functional characteristics of the gas turbine at the new point, the gas turbine thermodynamic equations were derived. These relationships include the relationship between the conservation of mass, conservation of energy and fuel chemical balance. Output parameters in this model is compressor pressure ratio, fuel mass flow rate, air mass flow rate, turbine inlet temperature, power of turbine and compressor and net power output of gas turbine. To check the results, industrial gas turbine V94.2 is selected. As a result of fuel change, for achieve turbine inlet temperature is 1400 K, 5 times the fuel mass flow rate should be increase. Surge margin on compressor operating line is decreased and the net output power increase about 8 percent.
