Development of the integrated gasification combined cycle (IGCC) power generation of various gasifying methods has been preceded in the world. Gasified fuels are chiefly characterized by the gasifying agents and the synthetic gas cleanup methods and can be divided into four types. The calorific value of the gasified fuel varies according to the gasifying agents and feedstocks of various resources. In particular, air-blown gasified fuels provide low calorific fuel of 4MJ/m^3 and it is necessary to stabilize combustion. In contrast, the flame temperature of oxygen-blown gasified fuel of medium calorie between approximately 9-13MJ/m^3 is much higher, so control of thermal-NOx emissions is necessary. Moreover, to improve the thermal efficiency of IGCC, hot/dry type synthetic gas cleanup is needed. However, ammonia in the fuel is not removed and is "supplied into the gas turbine where fuel-NOx is formed in the combustor. Suitable combustion technology for each gasified fuel is important. This paper outlines combustion technologies and combustor designs of gas turbine for various IGCCs.
