摘要： An improvement of a coal firing device applied to coal gasifiers, boilers for power generation, etc. On the inner walls of a ceiling portion (4) of a firing furnace (3) and of a throat portion (2) thereabove, and of a diffuser portion (6) further thereabove, where necessary, plate-like vortex breaker(s) (1A, 1B) is/are provided. Vortex flow of gas in the vicinity of the inner wall surface around the throat portion (2) is thereby weakened and molten slag sticking on the wall surface is suppressed to be pushed up by the gas. There occurs neither staying of molten slag at the diffuser portion (6) nor scattering of slag, and blockade of furnace due to solid-phase slag does not occur.

摘要： In order to stably maintain a combustion capability in a combustion furnace for coal gassification, it is necessary to exhaust molten slag produced within the furnace without the slag stagnating. The present invention provides, in a combustion furnace for coal gassification, a slag exhausting device which is configured in such a manner that the cooling of molten slag being exhausted from the furnace is minimized to prevent the slag from solidifying and causing other slag to stagnate. The slag exhausting device is disposed at the center of a bottom wall of the combustor, and has a lower cylindrical portion and an upper bank opening upwardly and flared at an angle of 300.degree.-45.degree.. The height H from the bottom wall to the top of the upper bank, a height L and an inner diameter ds of the cylindrical lower portion and a diameter D of the combustor are set to satisfy the relations of ds/D=0.2-0.4, L/ds=0.2-0.6 and H/D=0.05-0.15.

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： A boiler furnace combustion system typically includes main burners disposed on side walls of or at corners of a square-barrel-shaped boiler furnace having a vertical axis, the burner axes being directed tangentially to an imaginary cylindrical surface coaxial to the furnace. Air nozzles are disposed in the boiler furnace at a level above the main burners, so that unburnt fuel left in a reducing atmosphere or a lower oxygen concentration atmosphere of a main burner combustion region can be perfectly burnt by additional air blown through the air nozzles. The present invention provides two groups of air nozzles disposed at higher and lower levels, respectively. The air nozzles at the lower level are provided at the corners of the boiler furnace with their axes directed tangentially to a second imaginary coaxial cylindrical surface having a larger diameter than the first imaginary coaxial cylindrical surface. And, the air nozzles at the higher level are provided at the centers of the side wall surfaces of the boiler furnace with their axes directed tangentially to a third imaginary coaxial cylindrical surface having a smaller diameter than the second imaginary coaxial cylindrical surface.

摘要： An integrated coal gasification combined cycle facility is provided that can prevent a reduction in power generation efficiency even when low-grade coal having a relatively-high moisture content is used. Included are: a gasification section that gasifies supplied coal; a gas power generation section that generates power by using gas supplied from the gasification section; a steam power generation section that generates power by using the heat of exhaust gas discharged from the gas power generation section; and a coal drying unit that dries the coal by using exhaust heat discharged from the steam power generation section and that supplies the dried coal to the gasification section.

摘要： A pulverized fuel firing apparatus comprises a first pulverized fuel injection compartment so constructed that the combined amount of primary air and secondary air to be consumed is less than the theoretical amount of air required for the combustion of the pulverized fuel to be fed as mixed with the primary air to a furnace, a second pulverized fuel injection compartment so constructed that the combined primary and secondary air amount is substantially equal to the theoretical air for the pulverized fuel to be fed together with the primary air, and a supplementary air compartment for injecting supplementary air into the furnace. The three compartments are arranged close to one another and control the NOx production upon combustion of the pulverized fuel.

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.
