    Abstract: In order to provide a rotary-furnace burner in which the quantity fraction of cost-effective particulate secondary fuels to be used as energy carriers can be increased and the configuration of the burner flame can be influenced, even during the operation of the burner, it is proposed, according to the invention, to arrange an expansion chamber open towards the burner mouth and having a widened cross section, as compared with the tube or individual tubes in the burner in front of the issue of the tube or tubes for blowing out the secondary fuels, and to make the axial length and the volume of the expansion chamber variable, during the operation of the burner, by means of the axial displacement of the secondary-fuel tubes, so that the particulate secondary fuel particles blown out at the burner mouth with a considerably reduced velocity do not fly past the burner flame, but, instead, burn out in the flame.

    Abstract: A burner includes a primary air-coal mixture duct coaxially extended through a secondary air wind box, a pulverized coal separator supported within the primary air-coal mixture duct, a secondary air duct including an inner secondary air duct and an outer secondary air duct coaxially formed around the primary air-coal mixture duct, a primary air-coal mixture conical outlet coupled with the outlet of the primary air-coal mixture duct, and inner secondary air and outer conical outlets coupled with the outlets of the inner secondary air and outer secondary air ducts respectively. The conical outlets are arranged to delay the mixing time of the primary air-coal mixture and secondary air flows through the primary air-coal mixture and secondary air ducts and to prolong the residence time in the center recirculation zone under the reduction ability so as to effectively reduce the formation of NOx.

    Abstract: A mixture of pulverized coal and primary air travels axially through a tubular nozzle body having an outlet end in and surrounded by axially flowing concentric streams of secondary and often tertiary air. In the nozzle body, the coal/air mixture flows through a venturi that concentrates the coal in a fuel rich central zone. The coal/air mixture then flows through a spreader that imparts a swirling motion to the mixture and divides the mixture into multiple discrete lobes or streams. At the outlet end of the nozzle body, a flame stabilizer ring produces a separation zone between the coal/air mixture exiting the nozzle body and the surrounding flow of secondary air. The flame stabilizer ring includes an outwardly flared skirt section that spreads the secondary air flow and inwardly directed teeth that extend into the streams of coal/air mixture flowing from the nozzle body outlet.

    Abstract: A burner outlet set for a downshot firing burner is described comprising a first outlet array having at least one primary outlet, and at least one vent air outlet disposed either side of the primary outlet in an array direction of the first outlet array; second and third outlet arrays each comprising an array of secondary air outlets, respectively disposed either side of the a first outlet array. A burner system with a plurality of such burner outlet sets, a burner arch configured for downshot firing and having one or more such burner sets, and a combustion furnace with one or more such arches are also described.

    Abstract: A wide-flame solid fuel/oxygen burner including a fuel nozzle having an aspect ratio of at least about 2 defined by the ratio of a fuel nozzle width, W, measured along a major axis centerline, to a fuel nozzle height, H, measured along a minor axis centerline, and long walls spaced substantially symmetrically from the major axis centerline, the fuel nozzle having an inlet width, WN; and a pair of guide vanes positioned on either side of the major axis centerline between that centerline and an adjacent long wall, the guide vanes diverging from the major axis centerline in the flow direction by an angle such that the guide vanes are closer together at an upstream end and farther apart at a downstream end, thereby forming a central diffuser between the guide vanes and an outer converging nozzle between each guide vane and one of the long walls.
