Abstract
Abstract This invention describes an improved gas burner assembly, in which the entire burner assembly is enclosed in a housing which is supported from a flat plate, which is mounted to the steel outer wall of the furnace. The plate is spaced from the furnace to provide entry of air to the burner. The air flows radially along the outer wall of the furnace, cooling the wall, and then into the primary and secondary air inlets of the burner. The housing serves to contain and dampen the high noise level of the burner created by the high speed flow of gas through the nozzle. The noise can still further be reduced by lining the inside of the housing with acoustic insulation. This improved construction can be applied to any type of gas burner.

Claim 1
Independent Claim
201 words
In a gas burner assembly for furnaces in which a stream of high velocity fuel gas issues from an orifice to aspirate combustion supporting air into, and mix with said air, in a mixing section of a burner pipe, said burner pipe inserted through an oversize opening through a portion of the wall of said furnace, said mixed gas issuing from the tip of said burner pipe to form a flame inside said furnace, the heat from which travels through said furnace wall to the outer surface thereof, the improvement comprising, means to cool said outer surface, preheat said combustion-supporting air and to reduce the noise issuing from said burner assembly, comprising: a. housing means substantially covering that portion of said burner assembly extending outward from said outer wall of said furnace, said housing including a mounting plate, b. said mounting plate fastened to said outer wall of said furnace through spacer means which provide a selected width of opening between said outer wall and said mountiNg plate for the entry of combustion supporting air to said burner, and c. means to direct the flow of said combustion supporting air into heat-transferring air-warming contact with said outer wall of said furnace.

Claim 3
Dependent Claim
11 words
The improvement of claim 1 including acoustical-energy-absorbing material inside said housing.
Claim 4
Dependent Claim
17 words
The improvement of claim 1 including means to mechanically support said burner assembly from said housing means.
Claim 5
Dependent Claim
37 words
The improvement of claim 1 including a recess in said outer surface of said furnace wall, and deflector means on said housing to direct the air flowing into said housing into heat-transferring contact with said recessed surface.
Claim 6
Dependent Claim
33 words
The improvement of claim 1 including radial grooves in said outer surface of said furnace wall, and means to direct the combustion supporting air flowing into said housing to flow into said grooves.
Claim 7
Dependent Claim
35 words
The improvement of claim 1 including radial ridges on the inner surface of said furnace wall in the vicinity of said burner, said ridges adapted to be heated to incandescence by the burning fuel-air mixture.
Claim 8
Dependent Claim
248 words
In a gas burner assembly for furnaces in which a stream of high velocity fuel gas issues from an orifice to aspirate combustion supporting air into, and mix with said air, in a mixing section of a burner pipe, said burner pipe inserted through an oversize opening through a ceramic block forming a portion of the wall of said furnace, said mixed gas issuing from the tip of said burner pipe through radial openings to form a flame inside said furnace, said ceramic block containing radial ribs extending outward from the inner surface of said ceramic block, said ribs adapted to be impinged upon, and to be heated, thereby, by said flame, part of the heat of said flame traveling through said ceramic block to the outer surface of said block, the improvement comprising; means to cool the outer surface of said block, preheat the combustion-supporting air, and to reduce the noise issuing from said burner assembly, comprising: a. housing means substantially covering that portion of said burner assembly extending outward from the outer surface of said furnace wall, said housing including a mounting plate, b. said mounting plate fastened to said outer surface of said furnace wall through spacer means which provide a selected width of opening between said outer surface and said mounting plate for entry of combustion-supporting air to said burner, and c. means to direct the flow of said combustion-supporting air into heat-transferring and air-warming contact with the outer surface of aid ceramic block.
