Abstract
Combustibles such as wastes are gasified in a fluidized bed. A fluidized-bed furnace has a heat recovery region in addition to a combustion region. The temperature of a fluidized bed or the temperature of a freeboard is controlled so as to be kept at a predetermined value by adjusting the heat recovery rate in the heat recovery region.
