Effect of Variation of Fuel Composition on Gas Turbine Off-Design Performance

Abstract:

The effects of fuel composition is investigated in a gas turbine for natural gas. Fuel composition is divided H/C ratio and heating value. There are three control schemes for gas turbine. In this study, TIT control and TET control is adopted. A full off-design analysis of the gas turbine was performed. Performance characteristics and maximum turbine blade temperature are the main interests. The power output is decreased while heating value of fuel is increased and H/C ratio of fuel is decreased both control scheme. As heating value of natural gas decreased and H/C ratio of fuel increased, turbine blade temperature is increased in TIT control. Otherwise, Blade metal temperature is little influenced by H/C ratio of fuel in TET control scheme.
