ABSTRACT:
A flare stack with smokeless burn and reduced steam consumption. The flare stack includes a central pipe having a flare tip. The flare tip has a top edge. An outer pipe surrounds the central pipe and forms an annulus between them. A spreader spreads gas from the central pipe into the annulus. Steam and air, with oxygen, are forced into the base of the annulus and past the spreader to mingle with the gas and create smokeless burning. Steam and air are supplied by at least one conical conduit leading into the annulus, the conduit having an inlet for the flow of steam into it, a steam manifold having an outlet corresponding to each conduit, each outlet being directed towards a corresponding inlet in the conduit; and an opening between each outlet and inlet for the flow of air into each conduit drawn by a venturi effect.
