Abstract
Abstract An oil burner comprises a burner tube with an atomizing nozzle disposed axially thereof and between a pair of directional baffles, one downstream and the other upstream with respect to the nozzle, the upstream baffle controlling and directing combustion air in an axial flow and the downstream baffle imparting a spiral swirl to the air and the atomized fuel. An axial flow blower supplies air to the burner tube.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
164 words
An oil burner comprising a burner tube having inlet and outlet ends, means for supplying combustion air to said inlet end of said burner tube, a first baffle disposed in said burner tube inwardly from said inlet end, said first baffle comprising a plurality of thin relatively wide circular vanes spaced radially with respect to the axis of said burner tube to direct said combustion air axially of said burner tube and a secondary baffle in said burner tube adjacent said discharge end thereof and having a central opening therein, a fuel delivering nozzle disposed in said burner tube between said first and secondary baffles and direcTed toward said opening in said secondary baffle and means for supplying fuel to said nozzle, a plurality of radially extending fan-like blades positioned circumferentially in said secondary baffle and arranged to impart a spiral swirl to the axial flowing air in the burner tube so as to mix the same thoroughly with fuel delivered by said nozzle.
Claim 2
Dependent Claim
164 words
An oil burner comprising a burner tube having inlet and outlet ends, means for supplying combustion air to said inlet end of said burner tube, a first baffle disposed in said burner tube inwardly from said inlet end, said first baffle comprising a plurality of thin relatively wide circular vanes spaced radially with respect to the axis of said burner tube to direct said combustion air axially of said burner tube and a secondary baffle in said burner tube adjacent said discharge end thereof and having a central opening therein, a fuel delivering nozzle disposed in said burner tube between said first and secondary baffles and direcTed toward said opening in said secondary baffle and means for supplying fuel to said nozzle, a plurality of radially extending fan-like blades positioned circumferentially in said secondary baffle and arranged to impart a spiral swirl to the axial flowing air in the burner tube so as to mix the same thoroughly with fuel delivered by said nozzle.
Claim 3
Dependent Claim
52 words
The oil burner of claim 1 and wherein each of said plurality of circular vanes is disposed at a small angle with respect to one another and with respect to the axis of said burner tube so as to direct said combustion air into a flowing column of uniform velocity and volume.
Claim 4
Dependent Claim
67 words
The oil burner of claim 1 and wherein said secondary baffle has a central area about said opening therein and inwardly of the inner ends of said fan-like blades and a plurality of circumferentially positioned angularly disposed vanes formed in said central area on the same plane as said fan-like blades and arranged to provide swirling turbulence in the combustion air and fuel flowing through said opening.
