COMBUSTION BURNER AND COMBUSTION APPARATUS PROVIDED WITH SAID BURNER |
摘要 |
A combustion burner includes a mixture nozzle, a gas supply nozzle, and guide means. 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 guide means 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 straightly along an inner peripheral surface of the flared portion of the mixture nozzle.
