ABSTRACT:
A flare burner for flaring or burning off combustible waste gases comprises a venturi burner tube, a waste gas supply pipe having a gas outlet opening at the throat of the venturi burner tube and forming an injector for drawing air through an intake into the venturi burner tube, and pilot burner jets for burning combustion maintenance gas projecting laterally through the wall of the venturi burner tube downstream of its throat. The dimensions of the burner are such that the ratios d' : d, D, h and a are in the ranges 1 : from 1.2 to 3 : from 2 to 6 : from 4 to 20 : from 3 to 15; where d' is the diameter of the gas outlet opening, d is the throat diameter of the venturi burner tube, D is the maximum diameter of the venturi burner tube downstream of its throat, h is the length of the venturi burner tube from its throat to its point of maximum diameter downstream of its throat, and a is the length of the venturi burner tube from its throat to the entry points of the pilot jets.
