<p>Apparatus for the smokeless combustion of gases, supplied at substantial pressure, such that they will aspirate the required combustion air when discharged to atmospheric pressure. The apparatus comprises a plurality of spaced apart burner assemblies, each of which has a plurality of orifices arranged in a circular symmetrical pattern. Each burner assembly comprises a vertical tube supplying gas, with a plurality of short substantially radial arms, each of which has a plurality of orifices in its top surface. The arms themselves are tilted upwardly at a selected angle to the horizontal so that the orifices that are perpendicular to the arms will provide gas jets which will intersect each other along the axis of the assembly. In another embodiment, the top surface of the arms form a plane fingered plate of substantial thickness. The orifices are drilled at a selected angle toward the axis, in the top surface of the plate. In a third embodiment, each burner assembly comprises a toroid, or circular ring of pipe, with a plurality of circumferentially spaced orifices in the top surface of the pipe inclined at a selected angle to the plane of the pipe.</p> |
