<p>A circulation type gasification furnace (100) is provided with: a gasification furnace (108) which turns a fluidizing medium into a fluidized bed or a moving bed and gasifies a gasification raw material injected into the fluidizing medium with the heat that the fluidizing medium has in order to generate gasified gas; a combustion furnace (102) which heats the fluidizing medium discharged from the gasification furnace and burns the gasification raw material residue; a medium separator (104) which separates the fluidizing medium and combustion exhaust gas discharged from the combustion furnace in order to return the heated fluidizing medium to the gasification furnace; a gasified gas separator (112) which separates the gasified gas generated in the gasification furnace and the gasification raw material residue and discharges the gasified gas; and a residue discharge section (114) which discharges the residue separated by the gasified gas separator into the combustion furnace while sealing the gasified gas separator and the combustion furnace. This circulation type gasification furnace maintains utilization efficiency of the gasification raw material and suppresses solid particles from scattering repeatedly in the gasification furnace so that the gasified gas is appropriately discharged from the gasified gas separator.</p> |
