Abstract
PURPOSE:To enable efficiency continuous operation of a boiler by using alumina balls of alumina purity of at least specific percentage or more in dense bed material of a fluid bed formed in a furnace of circulating fluid bed boiler. CONSTITUTION:In regard to a furnace having fluid bed, a cyclone which is connected with the furnace and whose lower part communicates with an outer heat exchanger and a circulating fluid bed boiler to connect the outer heat exchanger and the furnace, dense bed material 7 used as a part of fluid bed material is formed as the alumina balls of alumina purity of 30%. To put it in the concrete the dense bed material is fluidized in a fluid bed area, circulating bed material R of grains supplied in the fluid bed area is uniformly fluidized to work, but the size of the dense bed material 7 is selected by its specific gravity and air (gas) speed P at which air is flowed in through a dispersion plate 25 in the furnace.
