<P>PROBLEM TO BE SOLVED: To provide a nitrogen gas production apparatus efficiently supplying nitrogen and oxygen required in an integrated gasification combined cycle system under conditions adapted to the status of use, and to provide a gasification combined power system having high energy efficiency by using the nitrogen gas production apparatus. <P>SOLUTION: The nitrogen gas production apparatus produces and supplies nitrogen gas N used in a gasification furnace facility 2 and/or a gas purification facility 3 from material air A, and supplies oxygen-rich waste gas B obtained by separating the nitrogen gas N from the material air A to the primary side of an air compressor 24 installed in the gasification furnace facility 2, and introduces the waste gas B as a part of the gasification agent in a gasification furnace 22 after being pressurized together with air in the air compressor 24. <P>COPYRIGHT: (C)2012,JPO&INPIT |
