Brais, N; Chouinard, J G

An air-cooled oxygen-gas burner for use with a direct fired furnace is described, said burner comprising a burner body formed by three concentrically disposed metal tubes supported in spaced relationship to define first and second chambers there between, an injection nozzle at an inner end of said metal tubes including frusto-conical shaped end sections and defining a first and second adjustable annular port there between, a third adjustable annular port defined between an outer one of said metal tubes and a frusto-conical bore of predetermined shape formed in a refractory wall of a furnace, a cylindrical housing for securement about said bore outside said refractory wall, said burner body being supported in spaced concentric position within said cylindrical housing to form a third chamber there between, a spark plug disposed at a free end of said injection nozzle, adjustable means to feed under pressure a combustible gas and oxygen in said first and second chambers respectively, further adjustable means to feed air under pressure in said third chamber, and means to axially displace said three metal tubes independently from one another to vary the size of said adjustable annular ports between said frusto-conical shaped end sections to thereby vary the shape of a flame produced at said nozzle free end by combustion of a mixture of said combustible gas, oxygen and air, said adjustable means controlling the injection velocities to thereby vary the intensity of said flame.
