Abstract
Abstract A gas burner comprising a row of a plurality of gas nozzles coupled to a common gas supply and a plurality of rows of air nozzles extending on both sides of the row of gas nozzles parallel thereto. The air nozzles have a respective separate common air supply. The air nozzles and gas nozzles have intersecting directions of discharge for mixing the gas and air. The rows of air nozzles are symmetrically distributed with respect to the row of gas nozzles and are arranged so that the number of air nozzles in each row decreases from row to row in correspondence with increase of distance from the row of gas nozzles. The air nozzles in symmetrical rows on opposite sides of the row of gas nozzles have uniform cross-sectional discharge areas and these increase from row to row in correspondence with increase in distance from the row of gas nozzles. The arrangement of the gas nozzles and air nozzles can be such as to provide a plurality of individual pyramids.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
172 words
A gas burner comprising a row of a plurality of gas nozzles, gas supply means coupled to said nozzles, a plurality of rows of air nozzles extending on both sides of said row of gas nozzles parallel thereto, said air nozzles and gas nozzles having respective discharge axes which lie in intersecting planes and air supply means coupled to said air nozzles for supplying the same with air at a uniform pressure, said rows of air nozzles being symmetrically distributed with respect to said row of gas nozzles and arranged so that the number of air nozzles in each row decreases from row to row in correspondence with increase of distance from the row of gas nozzles, the air nozzles in symmetrical rows on opposite sides of the row of gas nozzles being in confronting relation and having intersecting directions of discharges and uniform cross-sectional discharge areas, the cross-sectional discharge area of the air nozzles increasing in successive rows in correspondence with their increase in distance from the row of gas nozzles.
Claim 2
Dependent Claim
172 words
A gas burner comprising a row of a plurality of gas nozzles, gas supply means coupled to said nozzles, a plurality of rows of air nozzles extending on both sides of said row of gas nozzles parallel thereto, said air nozzles and gas nozzles having respective discharge axes which lie in intersecting planes and air supply means coupled to said air nozzles for supplying the same with air at a uniform pressure, said rows of air nozzles being symmetrically distributed with respect to said row of gas nozzles and arranged so that the number of air nozzles in each row decreases from row to row in correspondence with increase of distance from the row of gas nozzles, the air nozzles in symmetrical rows on opposite sides of the row of gas nozzles being in confronting relation and having intersecting directions of discharges and uniform cross-sectional discharge areas, the cross-sectional discharge area of the air nozzles increasing in successive rows in correspondence with their increase in distance from the row of gas nozzles.
Claim 3
Dependent Claim
41 words
A gas burner as claimed in claim 1 comprising a plurality of spaced tunnel-like deflector plates each individually disposed above a respective gas nozzle and having outer surfaces facing the innermost row of air nozzles whose discharge air is directed thereagainst.
Claim 4
Dependent Claim
37 words
A gas burner as claimed in claim 2 wherein the directions of discharge of symmetrical rows on opposite sides of the row of gas nozzles intersect in the plane of symmetry through said row of gas nozzles.
Claim 5
Dependent Claim
27 words
A gas burner as claimed in claim 2 wherein said rows of air nozzles are arranged in steps on opposite sides of said row of gas nozzles.
Claim 6
Dependent Claim
24 words
A gas burner as claimed in claim 4 wherein said steps successively increase in correspondence with the distance from the row of gas nozzles.
Claim 7
Dependent Claim
35 words
A gas burner as claimed in claim 2 wherein a plurality of rows of said gas nozzles are provided and are associated with rows of said air nozzles to form a plurality of individual pyramids.
