BIOMASS GASIFICATION SYSTEM AND PURIFICATION METHOD OF BIOMASS GASIFICATION GAS

摘要

PROBLEM TO BE SOLVED: To provide a biomass gasification system which can simultaneously remove a tar component and a multicomponent of a sulfur compound in a gasified gas which is formed by gasifying biomass, and to provide a biomass gasification purification method.

SOLUTION: The biomass gasification system includes: a biomass gasification furnace 13 which gasifies a biomass 11 supplied by a biomass feeder 12; a first dust remover 15 which removes a gasification char contained in a generated gas 14 which is a gasified gas formed by the biomass gasification furnace 13; a generated gas cooler 16 which cools the generated gas 14 from which the biomass gasification char 30 has been removed with the first dust remover 15; a second dust removal means 17 which removes a dust in the generated gas 14 after cooling; and an adsorption column 18 which is filled up with a char adhesion biomass particle 31 which is adhered with the char 30 which simultaneously removes the tar component and the multicomponent of the sulfur compound in the generated gas 14 from which dust removal has been carried out by the second dust remover 17.
