SYSTEM FOR GASIFICATION OF BIOMASS AND METHOD FOR OPERATION THEREOF

Document Type and Number:

WIPO Patent Application WO/2005/085397

Kind Code:

A1

Abstract:

[PROBLEMS] To provide a system for gasifying a biomass which allows the prevention of problems caused by a tar component in a fuel gas, and also can achieve the effective use form a thermal view point of the fuel gas including said tar component; and a method for operating the system. [MEANS FOR SOLVING PROBLEMS] In a supply system (3) for supplying a fuel gas from a gasification furnace (1) for forming the fuel gas from a biomass, to a system (2) for using the gas, a gas modification tower (4) being heated to a treating temperature required for the thermal decomposition of a tar component in the fuel gas is provided. And provided also is a fuel gas introduction system (5), which introduces a fuel gas from the gas modification tower (4) to the gasification furnace (1) as a fuel for a gasification furnace when said gas modification tower (4) has a temperature lower than the treating temperature.
