Wide-Flame, Oxy-Solid Fuel Burner

摘要

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.

1. A wide-flame solid fuel/oxygen burner comprising:
a fuel nozzle having an upstream-to-downstream flow direction, 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 first guide vanes positioned on either side of the major axis centerline of the fuel nozzle, each first guide vane being positioned between the major axis centerline and an adjacent one of the long walls, the first guide vanes diverging from the major axis centerline in the flow direction by a first angle such that the first guide vanes are closer together at an upstream end and farther apart at a downstream end, thereby forming a central diffuser between the first guide vanes and an outer converging nozzle between each first guide vane and one of the long walls.
