摘要： A novel gasifying combustion method is proposed. Fuel, desulfurizing agent and air are fed into a fluidized bed gasification furnace and a part of the fuel is gasified. Then 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. Then produced combustion gas is led into the combustor, in which the combustible gas is burnt with the combustion gas and air fed separately. A method for controlling the amount of air fed to the respective furnaces and the combustor is disclosed. A novel gasifying power generation method includes, in addition to the above-mentioned 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： In a method and apparatus for desulfurizing exhaust gas, wherein combustion furnace desulfurization and flue desulfurization by means of limestone are effected, a desulfurization rate is enhanced, a dust precipitator is operated stably, and generation of harmful substance (CaSO₃) is suppressed. The present invention proposed, in a desulfurization method wherein furnace desulfurization is carried out by charging limestone into a combustion furnace (10), fly ash in the combustion gas collected by a dust precipitator (30) is converted into slurry, and the slurry is sprayed into a flue of exhaust gas exhausted from the combustion furnace (10) to effect desulfurization of the exhaust gas, to perform heat-exchange between the exhaust gas desulfurized by spraying the slurry and the exhaust gas exhausted from the combustion furnace (10). Also, the present invention relates to an apparatus for practicing the above-described method. Furthermore, according to the present invention, in a desulfurization method, wherein desulfurization within a combustion furnace (10) and desulfurization within a flue by means of limestone are effected, collected fly ash is converted into slurry by means of hydrogen peroxide, or after collected fly ash was again charged into the combustion furnace (10) it is collected and used as a desulfurizing agent within a desulfurizing flue (20).

摘要： The known boiler furnace combustion system of the type that main burners are disposed on side walls of or at corners of a square-barrel-shaped boiler furnace having a vertical axis, the burner axes are directed tangentially to an imaginary coaxial cylindrical surface, also additional air blow nozzles are disposed in the boiler furnace at a high level than the main burners, so that unburnt fuel left in a reducing atmosphere or a low oxygen concentration atmosphere of a main burner combustion region can be perfectly burnt by air blown through the additional air blow nozzles, is improved. The improvements reside in that the additional air blow nozzles are disposed as divided into at least two groups at higher and lower levels, the additional air blow 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 additional air blow 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.
