SYSTEM FOR GASIFYING RAW MATERIAL TO BE GASIFIED

摘要

PROBLEM TO BE SOLVED: To provide a gasifying system by which the formation of clinker and the occurrence of agglomeration caused in a gasification furnace are prevented when a solid material removed and collected when a raw material to be gasified is gasified by a gasification apparatus to form a synthetic gas is returned to the gasification furnace as a raw material to be re-gasified, and the gasification efficiency is improved by carrying out the regasification.

SOLUTION: The system for gasifying the raw material to be gasified is constituted as follows. Incombustibles Cs2 becoming the cause of the clinker formation are separated at a separation part 5, and only unburned materials Cs1 are returned to the gasification furnace 2 as the gasification raw material M' to prevent the formation of the clinker and to improve the gasification efficiency in the gasification furnace 2 by installing a first removing part 3 for removing the solid materials Cs in gas G1 formed in the gasification furnace 2, and the separation part 5 for separating the unburned materials Cs1 from the incombustibles Cs2 contained in the solid materials Cs removed at the first removing part 3.
