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 partitionfor regulation of bed material flow is arranged between positions I and II of a downcomerof a separatorand of a supply flow passagein plane of a fluidized bed gasification furnace. As a result, the bed material introduced via the downcomeris directed to a supply flow passagethrough a circuitous flow passagethroughout the fluidized bed gasification furnacedefined by the heat-resistant partition
