FLUIDIZED-BED GASIFICATION METHOD AND APPARATUS

摘要

The present invention relates to a method and apparatus for effectively utilizing thermal energy possessed by a high-temperature combustion gas discharged from a combustor and utilizing high-temperature oxygen contained in the high-temperature combustion gas discharged from the combustor. A fluidized-bed gasification apparatus for gasifying combustibles in a fluidized-bed furnace comprises a gasification furnace (2) for gasifying combustibles therein, and a combustion furnace (1) for combusting combustible components therein. The fluidized medium moves between the gasification furnace (2) and the combustion furnace (1), and exhaust gas discharged from another combustor is utilized as a fluidizing gas in the combustion furnace (1).
