摘要： A fluidized-bed combustion system for a boiler, a heating furnace for heating steels or the like, in which a plurality of gas distribution pipes are disposed at the bottom of the combustion chamber. The lower end of each gas distribution pipe is communicated with an air supply line with an air flow rate control valve and a fuel supply line with a fuel flow rate control valve and the air and fuel admitted into the gas distribution pipe are mixed within the same and the air and fuel mixture is injected or sprayed into the fluidized bed through injection ports of the gas distribution pipe which are positioned adjacent to the bottom of the fluidized bed, whereby the complete combustion within the fluidized bed can be ensured and the combustion can be controlled over a wide range and optimized depending upon a load.

摘要： A combustion furnace or reactor with a multi-stage fluidized bed system wherein upper and lower fluidized bed formation zones in which the fluidized beds of bed particles containing particles of lime stone are separated through a partition device. The partition device is provided with a plurality of exhaust gas distribution holes for distributing the exhaust gases produced in the lower fluidized bed into the upper fluidized bed and a plurality of nozzles through which issue the combustion air and/or recirculated exhaust gases into the upper fluidized bed. Combustion products such as NO.sub.x and SO.sub.x are desulfurized and denitrified respectively within the reactor by calcium compounds which absorb SO.sub.2 and act as catalysts for reducing NO.sub.x.

摘要： Distribution nozzles are arranged on an air distribution plate disposed at the lower portion of a furnace and spaced apart by a predetermined distance from the bottom thereof and one or more spouted nozzles extend upwardly from the air distribution plate so that not only a fluidized bed defined by the air discharged through the distribution nozzle but also one or more spouted beds defined by the air flows injected through the spouted nozzle or nozzles into the fluidized bed are formed within the furnace. Because of the coexistence of the fluidized bed and the spouted bed or beds, the agitated effect in the fluidized bed is enhanced and the combustion efficiency as well as the desulfurization can be pronounced. A particle feeding pipe is connected to the furnace to feed fuel and desulfurizing agent into the furnace. Secondary air from a secondary air supply pipe and portion of ash extracted through the bottom of the furnace by feed means are fed into the furnace at a position higher than the position of the opening of the particle feeding pipe into the furnace. A dust collector is disposed at a top of the furnace to circulate the ash trapped into the fluidized bed, whereby combustion efficiency as well as response to variations of load over a wide range can be ensured.

摘要： Unreacted gas generated at outside is introduced through a gas inlet tangentially into a secondary combustion chamber with a substantially cylindrical side wall, so that a spiral ascending flow of the unreacted gas is generated in the chamber. A bulk material in the chamber is blown up by the unreacted gas introduced through the gas inlet to be circulated in the chamber so as to substantially completely burn unburnt solids entrained in the unreacted gas.
