METHOD FOR OPERATING FLUIDIZED BED GASIFICATION APPARATUS AND FLUIDIZED BED GASIFICATION APPARATUS, COAL GASIFICATION HYBRID POWER SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a fluidized bed gasification apparatus in which a gasification furnace and a desulfurization equipment can stably be operated to prevent the formation of coagulated particle, and to provide a coal gasification hybrid power system.;SOLUTION: The method for operating the fluidized bed gasification apparatus 6 having an oxidation furnace 4 to which the gasification residues discharged from the gasification furnace 2, a desulfurizing agent discharged from a desulfurization equipment 3, and a gas containing oxygen are supplied to burn the gasification residues with the gas containing oxygen and simultaneously react calcium sulfide in the desulfurizing agent with oxygen into calcium sulfate, is characterized by supplying coal to the oxidation furnace 4 so that an oxidation concentration in a gas at the exit of the oxidation furnace 4 is maintained at a prescribed value during the operation.;COPYRIGHT: (C)2007,JPO&INPIT
