Low-calorific-value fuel gas turbine is essential to the economic development,energy conservation and pollution reduction,of which the key problem is the combustion characteristics and operating conditions. According to the characteristic curve of gas turbine compressor,the turbine characteristic curve and thermodynamic cycle process,this paper analyzes and calculates the thermal properties of low calorific value of fuel gas,which concludes the calculation method of expansion work for different low calorific value of fuel. Through the expansion work was calculated,the influence of the calorific value of fuel on coefficient of fuel,outlet temperature of turbine,fuel flow and expansion work was presented,which provides theoretical basis for the design and the working condition adjustment of the gas turbine.
