CIRCULATION TYPE GASIFICATION FURNACE

摘要

A circulation type gasification furnace is provided with: a gasification furnace that turns a fluidized medium into a fluidized bed or moving bed, and produces gasification gas by gasifying a gasification raw material injected into the fluidized medium; a combustion furnace that heats the fluidized medium discharged from the gasification furnace and combusts residue of the gasification raw material; a medium separator that, in order to return the fluidized medium to the gasification furnace, separates the fluidized medium from a combustion exhaust gas discharged from the combustion furnace; a gasification gas separator that separates the gasification gas produced in the gasification furnace from the residue of the gasification raw material; and a residue discharge section that creates a seal between the gasification gas separator and the combustion furnace, and discharges the residue separated by the gasification gas separator into the combustion furnace.

1. A circulation type gasification furnace comprising:
a gasification furnace that turns a fluidized medium into a fluidized bed or moving bed, and produces gasification gas by gasifying a gasification raw material that has been injected into the fluidized medium using heat from the fluidized medium; a combustion furnace that heats the fluidized medium discharged from the gasification furnace and combusts residue of the gasification raw material; a medium separator that, in order to return the heated fluidized medium to the gasification furnace, separates the fluidized medium and a combustion exhaust gas from each other, the fluidized medium and the combustion exhaust gas being discharged from the combustion furnace; a gasification gas separator that separates the gasification gas produced in the gasification furnace and the residue of the gasification raw material from each other, and then discharges the gasification gas; and a residue discharge section that creates a seal between the gasification gas separator and the combustion furnace, and discharges the residue separated by the gasification gas separator into the combustion furnace.
