A flare gas burner is described in which a deflector shell approximating a half Venturi is disposed about the upper end of a waste gas delivery pipe equipped with standard pilot-flame igniters and flame stabilizers. A manifold on the lower end of the deflector delivers motive fluid (air, steam) under high pressure into the passageway between the deflector and pipe. The fluid is directed by the inwardly inclined upper lip of the shell into the path of emissions from the waste gas pipe. Heat shields and noise shields are incorporated into the assembly. Additional whirling and turbulence is imparted to the stream of motive fluid by appropriate shaping of spacer plates securing the deflector to the waste gas pipe. The structure is less complex than previously known devices, has improved ease of maintenance, and gives excellent performance in smokeless flaring of waste gas.
