    摘要： An oxygen combustion system includes a boiler to burn fuel using combustion gas composed of oxygen-rich gas and circulating flue gas, a dust remover disposed in a flue through which flue gas discharged from the boiler flows, a second flue leading the combustion gas to the boiler, the combustion gas being made by mixing the circulating flue gas extracted downstream of the dust remover with the oxygen-rich gas, a combustion gas heater exchanging heat between the flue gas flowing between the boiler and dust remover and the combustion gas flowing through the second flue, and a flue gas cooler disposed between the heater and the dust remover to cool the flue gas. A control unit controls at least one of a flow rate and cooling medium temperature of the flue gas cooler such that temperature of the flue gas introduced into the dust remover will be between 90° C. and 140° C.

    摘要： The invention provides a combustion apparatus which can inhibit an NOx generation even in the case of promoting a mixing between a high-temperature combustion gas and an air so as to intend to reduce an unburned combustible. In a combustion apparatus provided with a burner burning a fuel within a furnace in a theoretical air ratio or less, and an air port supplying a combustion air for a shortfall in the burner, a supply apparatus for supplying a nitrogen oxide generation inhibiting gas is provided in a mixing region between the both or near the mixing region. Further, the invention provides a wind box which can inhibit an NOx generation even in the case of promoting a mixing between a high-temperature combustion gas and an air so as to intend to reduce an unburned combustible. In a wind box having an air port arranged in a back flow side of the burner and supplying a combustion air for a shortfall in the burner, a supply apparatus for supplying a nitrogen oxide generation inhibiting gas is provided in a mixing region between the both or near the mixing region.

    摘要： A combustion burner includes a mixture nozzle, a gas supply nozzle, and a flow guide. The mixture nozzle extends toward an interior of a furnace, and defines a mixture passage through which a mixture containing powdered solid fuel and gas for transferring the solid fuel flows. A distal end portion of the mixture nozzle is flared so that a flow passage area of the mixture passage increases progressively in a direction of flow of the mixture. The gas supply nozzle radially surrounds the mixture nozzle to define between the gas supply nozzle and the mixture nozzle a gas passage through which a combustion oxygen-containing gas flows toward the furnace. The flow guide is provided within the mixture nozzle at a position upstream of the flared portion of the mixture nozzle with respect to a flow of the mixture so as to make the mixture flow straight along an inner peripheral surface of the flared portion of the mixture nozzle.

    摘要： Subject A solid fuel burner and its combustion method suited for encouraging fuel ignition and avoiding slugging caused by combustion ash, wherein a gas of low oxygen concentration (exhaust combustion gas) is used as a carrier gas of such a low grade solid fuel as brown coal. Means for Solving the Subject An additional air nozzle 12 for jetting additional air having a velocity component in the circumferential direction of a fuel nozzle 11 is provided in the fuel nozzle 11, thereby encouraging mixing between the fuel and air in the fuel nozzle 11. Further, the amount of air supplied from the additional air nozzle 12 is adjusted in response to the difference in combustion loads. Under light load, the amount of air supplied from the additional air nozzle 12 is increased so as to increase the oxygen concentration of the circulating flow 19 formed downstream of the outside of the outlet of the fuel nozzle 11, whereby stable combustion is ensured. Under heavy load, by contrast, the amount of air supplied from the additional air nozzle 12 is decreased, and a flame is formed away from the fuel nozzle 11 in such a way that burner structures and furnace wall will be less subjected to radiant heat.
