Abstract
Apparatus for the injection of steam for the smokeless combustion of waste gases, comprising an annular chamber of substantially the same inner diameter as the top of the flare stack, the chamber mounted on top of the flare stack and extending outwardly a selected radial distance, and vertically a selected height above the top of the flare stack. Steam is supplied to this annular chamber. A plurality of circumferentially spaced pipes are provided in the top of the annular chamber and are deflected outwardly in radial planes at selected angles. There are a plurality of inwardly and upwardly directed orifices for the injection of steam into the flame of the burning gases above the top of the annular chamber as well as to the gases prior to emergence for burning. Additionally, there may be a plurality of circumferentially spaced radial pipes inserted through the inner wall of the annular chamber in a horizontal plane a selected distance down from the top of the chamber. These pipes extend toward the axis of the stack and contain a plurality of orifices in the top quadrant of the pipes for the injection of steam into the rising flow of gas at a selected distance upstream of the plane of burning.
