Title: Gasification power generation system using preheated gasifying-agent to gasify fuel

Abstract: A gasification power generation system includes: a gasifying section for allowing a fuel, such as coal, to react with a gasifying agent, such as air, to produce a gasified product gas; a power-generating section for generating electricity using energy obtained by burning the gasified product gas, which is produced by the gasifying section; and a preheating section for preheating the gasifying agent supplied to the gasifying section, to a self ignition temperature of, e.g., about 1000.degree. C. The preheating section raises the temperature of air supplied into the gasifying section, to a high temperature of about 1000.degree. C. when a fossil fuel, such as coal, is used as the fuel. Thus, it is possible to achieve gasification power generation with a high generating efficiency using inexpensive, simple constructions and to realize a stable and low NOx combustion of the gasified product gas.
