ABSTRACT:
An improved ground flare is provided comprising a stack, two or more burner assemblies, and a servicing port so that some of the burner assemblies can be serviced while others remain in operation. The burner assemblies comprise a burner conduit and nozzles which are individually fitted to the stack's burner chamber and are each removably supported in the chamber. Preferably, the lower end of the stack is formed of one or more axially displaced lower tubular shells which are concentrically spaced for forming annular inlets for admitting additional combustion air. More preferably, an upper tubular exhaust stack, similarly formed, admits additional combustion air: for providing secondary combustion air for increasing the efficiency of combustion from the burner assemblies; for increasing the flow of exhaust gases for improved discharge momentum and atmospheric dispersion; and for cooling the upper stack. Additionally, the additional air permits the addition of auxiliary burners above the annular spaces wherein additional air supplies the necessary primary combustion air, enabling greater waste gas combustion throughput.
