Abstract
Fuel, desulfurizing agent and air are fed into a fluidized bed gasification furnace so that part of the fuel is gasified. The produced combustible gas is led into a combustor. Residual fuel not gasified within the fluidized bed gasification furnace is led to a fluidized bed combustion furnace jointly with the desulfurizing agent to burn it with air fed separately to the combustion furnace. Then produced combustion gas is led into the combustor, in which the combustible gas is burnt with the combustion gas and air fed seperately to the combustor. The amounts of air fed to the respective furnaces and the combustor are individually regulated. A gasifying power generation method includes, in addition to the abovementioned steps of the gasifying combustion method, the steps of driving a gas turbine by the combustion gas produced by the combustor, driving a steam turbine by steam generated by the combustion gas, and rotating electric generators by the respective turbines to carry out power generation.
