Abstract
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.
