    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: Temperature of exhaust gases from a fluidized-bed boiler is lowered by means of heat exchange and dust entrained in the exhaust gases is efficiently collected by a dust collector. Part of the gases discharged from the dust collector are mixed with heated combustion air and are charged into a fluidized bed. Therefore, problems caused by dust entrained in the exhaust gases to be mixed with the combustion air as well as the cold corrosion problem can be substantially solved so that the technique for reducing the NO.sub.x contents in the exhaust gases from the fluidized-bed boiler is satisfactorily established.

    摘要: A fuel supplied through a fuel feed bore of a burner plug and a spray medium supplied through spray medium feed holes thereof are mixed initially in primary mixing chambers in a burner plate and further mixed in a secondary mixing chamber in a burner tip and the fuel mixture thus obtained is sprayed through spray holes of the burner tip. Each of the primary mixing chambers is inclined at a predetermined angle relative to the axis of the burner plate so that the fuel mixture is caused to swirl in a secondary mixing chamber; or the burner plate and the burner tip are so interconnected to each other that the extension of the axis of each primary mixing chamber in the burner plate intersects substantially the midpoint between the adjacent spray holes of the burner tip and consequently the fuel mixture discharged from the primary mixing chambers impinges on the inner wall of the secondary mixing chamber in the burner tip, whereby the ability to atomize a slurry fuel is improved. Furthermore, thin ceramic layers are disposed at portions of the burner which are subjected excessive wear while the portions of the burner which are subjected to heavy thermal loads are made of a hard alloy so as to support the thin ceramic layers, whereby resistance to wear and safety of the burner are enhanced.
