Abstract
Abstract A power gas burner is provided having a perforated plate through which air passes and is mixed with gas introduced into the burner at right angles to the direction of airflow and immediately in front of the plate, to provide a combustible mixture which burns with a short, intense, flame, free from lifting and pulsation. A mantle of gas-free air surrounds the flame to avoid corrosion of parts of the burner. The air for combustion passes through the plate at a high velocity such as to create a partial vacuum at the front of the plate, which is effective to maintain the flame against the plate.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
194 words
In a burner of the character described, a tubular member for passage of air under pressure, a plate extending diametrically across said tubular member at a point spaced rearwardly from the forward end of said member, said plate having spaced perforations for the passage of air therethrough, means for introducing gas through said plate at points adjacent the periphery of said plate, and means for directing said gas into said air in a direction substantially perpendicular to the direction of airflow and in a plane closely adjacent and parallel to the forward face of said plate, to provide a combustible mixture which produces a short flame, substantially free of pulsation, said last-named means including tubular gas jet nozzles extending through said plate and having orifices in the said sidewalls thereof, said plate having peripheral portions thereof removed to provide arcuate openings or passageways adjacent the inner wall of said tubular member, so that a portion of the air passing through said tubular member passes through said passageways to provide a blanket or mantle of air which encompasses the periphery of said flame and is effective to prevent oxidation or corrosion of said tubular member.
Claim 2
Dependent Claim
194 words
In a burner of the character described, a tubular member for passage of air under pressure, a plate extending diametrically across said tubular member at a point spaced rearwardly from the forward end of said member, said plate having spaced perforations for the passage of air therethrough, means for introducing gas through said plate at points adjacent the periphery of said plate, and means for directing said gas into said air in a direction substantially perpendicular to the direction of airflow and in a plane closely adjacent and parallel to the forward face of said plate, to provide a combustible mixture which produces a short flame, substantially free of pulsation, said last-named means including tubular gas jet nozzles extending through said plate and having orifices in the said sidewalls thereof, said plate having peripheral portions thereof removed to provide arcuate openings or passageways adjacent the inner wall of said tubular member, so that a portion of the air passing through said tubular member passes through said passageways to provide a blanket or mantle of air which encompasses the periphery of said flame and is effective to prevent oxidation or corrosion of said tubular member.
