GASIFICATION FURNACE, METHOD FOR OPERATING THE GASIFICATION FURNACE, AND BIOMASS GASIFICATION TREATMENT METHOD

摘要

PROBLEM TO BE SOLVED: To provide a gasification furnace with a high degree of freedom capable of obtaining a synthesis gas of a desired ratio while suppressing the utilization of an external heat source.SOLUTION: Provided is a gasification furnace comprising: a biomass feed part 2; a steam feed part 3; a reaction tower 4 where a first region R1 flowing a biomass fed from the biomass feed part 2 in a jet floor formed by steam fed from the steam feed part 3 and a second region R2 in which the gas generated in the first region R1 flows are formed along the flowing direction of the reaction gas; a plurality of oxygen gas feed parts 5 (5a, 5b, 5c) of feeding an oxygen gas respectively to the first region R1 and the second region R2 in the reaction tank 4; and a feed amount regulation mechanism of regulating the gas feed amounts from each oxygen gas feed part 5 (5a, 5b, 5c).SELECTED DRAWING: Figure 1
