FLUIDIZED BED GASIFICATION METHOD AND APPARATUS

摘要

PROBLEM TO BE SOLVED: To increase production of high-quality gasified gas in a fluidized bed gasification furnace wherein a chamber to which an organic raw material is fed to produce pyrolysis gas containing tar through a pyrolytic reaction is separated from a chamber to which pyrolysis residue produced through the pyrolytic reaction is introduced to produce the gasified gas. SOLUTION: The fluidized bed gasification furnace 2 is composed of a first chamber 31 and a second chamber 32. The organic raw material M is fed to the first chamber 31 and subjected to the pyrolytic reaction in the first chamber 31 to produce the pyrolysis gas 55. The thermolysis residue M' produced through the pyrolytic reaction of the organic raw material M in the first chamber 31 is introduced into a fluidized bed 16 in the second chamber 32 to produce the gasified gas 35 through a gasification reaction.
