Abstract
An improved flare system in which steam is injected into the column of gas to be burned, from circumferential nozzles at at least two spaced levels, above the tip of the flare stack. A circular manifold surrounds the stack just below the tip and an even number of small diameter riser pipes are attached to the manifold, spaced equally circumferentially. The riser pipes have nozzles all of which are directed radially inwardly and upwardly at a selected angle. Half of the nozzles are spaced at a first selected distance above the tip of the flare stack, and the other half are positioned at a greater selected elevation above the tip of the flare stack. Alternate risers have different elevations of the nozzles. By this means, a minimum diameter of the cross-section of the gas flow is occluded by the steam flow.
