摘要： CaS oxidation has CaS particles oxidized into CaSO4 completely as far as to the interior of the particle. The interior of an oxidation apparatus 1 is partially partitioned by a partition 22 to thereby form a first fluidized bed 20 on the inner side, a second fluidized bed 21 on the outer side and a space portion 23 thereabove. A heat exchanger 27 having a baffle plate is disposed on the inner side of the partition 22 and an in-bed heat exchanger 33 is disposed on the outer side of same. A desulfurizing product-containing fine powder 204 and coarse powder 205 and a mixture gas 206 of nitrogen, oxygen and steam are supplied into the second fluidized bed 21. Also, coal 200 and coal char 201 are supplied into the first fluidized bed 20 from below. Of the particles 304 oxidized in the second fluidized bed 21 and supplied into the first fluidized bed 20 from below with the flow of a mixture gas 208, the fine powder entrains into the space portion 23 as entrained particles 300 and a major part thereof falls down into the second fluidized bed 21 as particles 207. The completely oxidized particles are discharged as discharged ash 303 and entrained ash 302.

摘要： 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.
