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.

Abstract: A precombustor system (300) including an ignition chamber (301) having a front wall (308), a central axis, a diameter Dic, and an outlet (313) configured to discharge a product gas (315). The ignition chamber (301) includes a central ignition oxygen injector (307) configured to inject a first oxygen stream from the front wall (308) substantially parallel to the central axis, and a tangential primary fuel injector (303) configured to inject a primary fuel stream tangential to the central axis at a location an axial distance Xpf downstream of the front wall (308). The ratio Xpf/Dic is from 0.25 to 4.0. The central axis forms an angle a with a vertical line of less than or equal to about 45 degrees. The trajectory of the primary fuel stream forms an angle θ with a plane that is perpendicular to the central axis of less than or equal to about 20 degrees. A method for combustion is also disclosed.
