ABSTRACT:
In a coal gasification power generator, coal gas 500 obtained by gasifying a coal 100 by a gasifying furnace is introduced into a desulfurization furnace in which the coal gas 500 is desulfurized by limestone 400. A coal gas 501 after desulfurization is burned by a combuster 5 after it has passed through a dust removing unit 3 so that high temperature combustion gas 800 is supplied to a gas turbine. The gas turbine 7 drives a power generating unit. Exhaust gas 801 from the gas turbine is supplied to an exhaust gas boiler 8. Char 60a produced in the gasifying furnace and limestone 60b containing CaS emitted from the desulfurization furnace are burned in an oxidation furnace, and by using the resultant combustion gas, water vapor introduced from the exhaust gas boiler 8 is heated by a heat exchanger, and thereafter it is supplied to the gasifying furnace as a gas. With the above construction, chemical energy possessed by the coal is effectively converted into electric energy, and also the rate of desulfurization of coal gasifying gas is improved thereby reducing emitted sulfur oxide.
