Noise and smoke retardant flare

Abstract

Abstract A flare for the burning of waste gases which is designed to provide a minimum of noise and smoke pollution, comprising a vertical stack having a shroud in the form of a cylinder surrounding, and spaced outwardly from, the top portion of the stack, and extending above the top of the stack. The space between the shroud and the stack is closed off by an annular plate which serves to support the shroud from the stack. At the top of the shroud is a steam manifold which carries a plurality of steam nozzles spaced angularly around the inner face of the manifold, so as to direct high velocity steam jets inwardly and upwardly toward the axis of the stack. The nozzles are placed on the inner face of the manifold so as to be substantially below and inside of the outer contour of the manifold and the shroud. The outer circumference of the shroud near its bottom end is perforated with a plurality of circumferentially spaced openings through which air can pass to the annular space between the shroud and the stack. The upwardly moving air mixes with the gas flowing up the stack, and burns in the wind-protected zone above the top of the stack, and below the top of the steam manifold. Above the top of the steam manifold the jets of steam driving into the rising column of burning gas carry in combustion air and throughly agitate and mix the combustion air, the steam, and the burning gas.
