摘要： A fluidized bed gasification system is provided in which bed material and raw material are passed throughout a fluidized bed gasification furnace so that raw material is gasified with higher gasification efficiency to improve gasification productivity. A heat-resistant partition 32 for regulation of bed material flow is arranged between positions I and II of a downcomer 12 of a separator 8 and of a supply flow passage 25 in plane of a fluidized bed gasification furnace 2. As a result, the bed material introduced via the downcomer 12 is directed to a supply flow passage 25 through a circuitous flow passage 33 throughout the fluidized bed gasification furnace 2 defined by the heat-resistant partition 32.

摘要： A fluidized bed gasification furnace has a fluidized bed formed and a freeboard section F above a bed material so as to produce a produced gas by a reaction of raw material with a gasifying agent and take out the produced gas through the freeboard section. Upon shutdown of the furnace, inert gas is fed from below to the furnace for purging of gas in the fluidized bed with inert gas while steam is supplied to a freeboard section above the fluidized bed to purge a gas in the freeboard section with steam.
