| description | A gasification furnace and a combustion furnace are integrated with each other to form a single fluidized-bed gasification and combustion furnace in which unburned char generated in the gasification furnace is combusted in the combustion furnace, and the thus generated heat of combustion is utilized as a heat source for gasification. The fluidized-bed gasification and combustion furnace ( 1 ) comprises a gasification furnace ( 3 ) and a combustion furnace ( 4 ) which are divided by a first partition wall ( 2 ). In the gasification furnace ( 3 ), a revolving flow of the fluidized medium is formed by diffusion devices ( 32, 33 ) provided on furnace bottoms, and an upward flow of the fluidized medium partly flows in the combustion furnace ( 4 ). The combustion furnace ( 4 ) is divided into a main partition wall ( 5 ). In the main combustion chamber ( 6 ), a revolving flow of the fluidized medium is formed by diffusion devices ( 34, 35 ) provided on furnace bottoms, and an upward flow of the fluidized medium partly flows in the heat recovery chamber ( 7 ). |
