METHOD FOR SUPPLYING OXYGEN-CONTAINING GAS TO FLUID BED TYPE GASIFICATION FURNACE, AND FLUID BED TYPE GASIFICATION FURNACE

摘要

PROBLEM TO BE SOLVED: To provide a method for supplying oxygen-containing gas to a fluid bed type gasification furnace, capable of increasing a temperature of pyrolysis gas discharged from a furnace body, even in a case where a temperature of a fluid bed is equal to or less than 550°C.;SOLUTION: A method for supplying oxygen-containing gas to a furnace body (10) of a fluid bed type gasification furnace, comprises a fluid bed formation step of fluidizing fluid medium with fluidized gas to form a fluid bed (18) in the furnace body (10), wherein a temperature of the fluid bed is equal to or less than 550°C; a waste supply step of supplying wastes to the fluid bed (18); and an oxygen-containing gas supply step of supplying oxygen-containing gas toward a surface of the fluid bed (18).;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2019,JPO&INPIT
