초록 ▼

An air-cooled oxygen-gas burner for use with a direct fired furnace. The burner comprises a body formed from three concentric metal tubes supported in a cylindrical housing secured about a conical bore in a refractory side wall of a furnace. The three concentric tubes have a cone shaped inner end which are adjustable to define a nozzle with annular openings therebetween of variable size to vary the shape of a flame produced by a mixture of combustible gas, oxygen and air fed under pressure, respectively, in each of two chambers defined between the three concentric metal tubes and a chamber defined between the tubes and the cylinder housing. The combustible gas is fed in the inner chamber, the oxygen in the intermediate chamber, while the air is fed in the outer chamber to cool the concentric tube assembly and the furnace refractory about the burner nozzle. The tube assembly can be retracted within the cylinder housing so that the nozzle is protected from the high heat within the furnace after the burner is shut off.

An air-cooled oxygen-gas burner for use with a direct fired furnace, said burner comprising a burner body formed by three concentrically disposed metal tubes supported in spaced relationship to define first and second chambers therebetween, 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 therebetween, 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 therebetween, 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.
