A gasification furnace () of a circulation fluidized bed-type gasification furnace () forms a fluid medium into a fluid bed, and produces gasified gas by gasifying an input gasification raw material using heat from the fluid medium. A combustion furnace () heats the fluid medium output from the gasification furnace. A flow rate adjuster () distributes the fluid medium heated in the combustion furnace to the gasification furnace and a buffer section (). In this manner, irrespective of the flow rate of the fluid medium in the entire circulation fluidized bed-type gasification furnace (), the buffer section () enables the fluid medium to bypass to the combustion furnace. As a result, the flow rate of the fluid medium in the gasification furnace () can be maintained at a desired flow rate.
