Pressurized Internally Circulating Fluidized Bed Gasifire has a gasification, a char combustion, and a heat recovery chamber in one single furnace, and has a large quantity of the circulating flow of the fluidized-bed material between chambers. PICFG the following characteristics. (1) Coal is pyrolyzed by using the combustion heat of char. Combustion of syngas can be managed in minimum. (2) Syngas from coal and char combustion gas are separately discharged from the furnace. (3) An oxidation region and a reduction region coexist in one single furnace. (4) The generated char is completely burned in a char combustion chamber. (5) The bed temperature of char combustion chamber can be controlled easily. The above characteristics can realize the stable operation and high efficiency of power generation, and high efficiency desulfurization can be obtained by the coexistance of an oxidation region and a reduction region.
