Performance Simulation of Gas Turbine Combined Cycle with Coke Oven Gas as Fuel

The resource of coke oven gas is very rich in China. Electric power generation from coke oven gas is helpful to save resource and protect environment. The model of key equipments of gas turbine combined cycle was approached in the thesis. The influence of air temperature on gas turbine combined cycle when firing no matter natural gas or coke oven gas was given. The part load performance of gas turbine combined cycle was also obtained. The results show that the net power and thermal efficiency of gas turbine combined cycle are decreased after firing coke oven gas. The economic performance of gas turbine combined cycle was also evaluated, and the results show that the project has great ability to make profit.
