Development of the integrated gasification combined cycle power generation of various gasifying methods has been preceded in the world. The gasified fuels are chiefly characterized by the gasifying agent and the synthetic gas clean-up method, and divided roughly into four types. The calorific value of gasified fuel differs according to the type of gasification agent. On the other hand, to improve the thermal efficiency, it is necessary to use a hot/dry type synthetic gas clean-up, but ammonia originated from nitrogenous compounds in coal is not removed. And then it forms fuel-NOx. For these reasons, the combustion technology for each gasified fuel is important. In this paper, we investigate influences of fuel compositions and calorific value on combustion emission characteristics, and effect of two-stage combustion on NOx emission characteristics through experiments using a small burner.
