Fuel supply condition determining method and the fuel supply condition determination program for the reduction method, as well as reduction of residual oxygen concentration in the gas raw material transport for the exhaust gas in the gasification gas power plant

摘要

PROBLEM TO BE SOLVED: To enable reduction of residual O₂ concentration in combustion exhaust gas of a gas turbine used as media for conveying gasification raw materials to a gasification facility in a gasification gas power plant.;SOLUTION: To gas turbine combustion exhaust gas before using as media for conveying a gasification raw material (coal C) to a gasification furnace 2, in other words, before supplying to a gasification raw material supply line 4, a part of gasification gas CG2 refined at a gas refining facility 3 or at least one of hydrogen and/or carbon monoxide and hydrocarbon extracted from the gasification gas CG2 are supplied.;COPYRIGHT: (C)2014,JPO&INPIT
