Residence time of a bed material in a gasification furnace (2) is controlled while the bed height is controlled by supplying the bed material separated by a medium separator (8) to the gasification furnace (2), charging a material, and extracting the bed material from one of bed material extraction ports (40a, 40b, 40c) connected at vertical intervals with the gasification furnace (2) and supplying the bed material to a combustion chamber (5). |
