<p>An air powered flare in which the blower or fan which provides the primary combustion air, is driven by a steam turbine, and the exhaust steam from the turbine is inserted into the stack to be mixed with the compressed primary air moving upwardly to a burner at the top of the flare stack. The mixture of low pressure steam and condensate in the exhaust from the turbine with the primary air serves to chemically improve the combustion of the fuel issuing from the burner, so as to facilitate its complete and smokeless combustion. Alternatively, it is possible to inject live steam into the column of primary combustion air in addition to or in place of the exhaust steam. Further, the live steam, and/or the exhaust steam can be ejected from nozzles surrounding the top of the flare stack and injected directly into the flame above the burner at the top of the flare stack.</p> |
