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.

摘要： 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.

摘要： A boiler recovers a soda component from pulp spent liquor and is able to prevent carry-over of unburnt char and deformation of a char bed configuration and to attain a stable combustion with low NOx generation. By regulating the combustion air supply, and feeding inert gas along a furnace side wall around the char bed, there are formed a combustion zone of reduction atmospheric field where air ratio in the surroundings of the char bed is 0.8 or less, a combustion zone of reduction atmospheric field where air ratio is 1.0 or less and unburnt components exist (including the case of a reduction atmospheric field where air ratio is 1.0 or less and unburnt components exist with the two combustion zones being combined together) and a combustion zone where combustion is completed.

摘要： A heavy oil emulsion fuel combustion apparatus is arranged, in a combustion apparatus using a heavy oil emulsion fuel, to prevent a decrease in the combustion efficiency due to water content in the fuel and to prevent an increase in the sulfuric acid dew point due to water content in the exhaust gas. A heavy oil emulsion fuel 101 from a fuel tank 100 is led to a fuel heater 110 and is heated. Then the heated heavy oil emulsion fuel 102 is led to a water content evaporator 120. In the water content evaporator 120, the heavy oil emulsion fuel 102 is heated by the use of extraction steam from a steam turbine facility 160 or steam produced through a steam converter 166, and the resulting fuel is led to a steam separator 140. In the steam separator 140, the fuel 111 is separated into steam and light oil combustible gas vapor 121 and a heavy oil portion 122, the latter 122 being used as boiler fuel 131. The steam and light oil combustible gas vapor 121 is used as a heat source for heating performed in the fuel heater 110.
