Claim 1
Independent Claim
189 words
An oil burner for installation in heating and steam-raising boilers having an oil atomizer device, comprising a first plate located downstream of the oil atomizer device and having at least one opening formed therein that defines a passageway for atomized oil and further defining the sole passageway for combustion air, a mixing tube positioned coaxially with respect to the opening in said first plate and spaced downstream therefrom having a diameter greater than the diameter of a circle surrounding the passageway in said first plate; a flame tube coaxially surrounding said mixing tube and having a length such that combustion gases flowing downstream of said mixing tube are received against an inner wall of said flame tube, and downstream of said first plate, an annular chamber for the supply of gaseous fuel having gas outlet openings in the region of said at least one opening in said first plate, said annular chamber being formed by said first plate and a second plate spaced a short distance downstream of said first plate, and at least one gaseous fuel supply tube being mounted on the upstream side of said first plate.
Claim 2
Dependent Claim

An oil burner for installation in heating and steam-raising boilers having an oil atomizer device, comprising a first plate located downstream of the oil atomizer device and having at least one opening formed therein that defines a passageway for atomized oil and further defining the sole passageway for combustion air, a mixing tube positioned coaxially with respect to the opening in said first plate and spaced downstream therefrom having a diameter greater than the diameter of a circle surrounding the passageway in said first plate; a flame tube coaxially surrounding said mixing tube and having a length such that combustion gases flowing downstream of said mixing tube are received against an inner wall of said flame tube, and downstream of said first plate, an annular chamber for the supply of gaseous fuel having gas outlet openings in the region of said at least one opening in said first plate, said annular chamber being formed by said first plate and a second plate spaced a short distance downstream of said first plate, and at least one gaseous fuel supply tube being mounted on the upstream side of said first plate.
Claim 3
Dependent Claim
14 words
An oil burner according to claim 1, said two plates being circular in configuration.
Claim 4
Dependent Claim
28 words
A burner according to claim 1, said two plates each having their outer circumferential edges offset axially and being sealed with one another at said outer circumferential edges.
Claim 5
Dependent Claim
27 words
A burner according to claim 3, sealing packings being positioned between said plates and determining the axial separation distances between said outer circumferential edges of said plates.
Claim 6
Dependent Claim
21 words
A burner according to claim 1, said gaseous fuel supply tube being mounted perpendicular to the plane of said first plate.
Claim 7
Dependent Claim
28 words
A burner according to claim 1, said second plate having an opening formed therein which is of larger diameter than the opening as formed in said first plate.
Claim 8
Dependent Claim
40 words
A burner according to claim 6, the edge of said opening in either said first or said second plate being flanged circumferentially in an axial direction, the end of said flange defining with the other plate a gas outlet opening.
Claim 9
Dependent Claim
30 words
A burner according to claim 1, a ring having gas outlet openings formed therein and being located between said first and second plates adjacent to said openings in said plates.
Claim 10
Dependent Claim
20 words
A burner according to claim 8, said ring having its internal circumference aligned with the opening in said first plate.
Claim 11
Dependent Claim
20 words
A burner according to claim 8, said ring having its internal circumference aligned with the opening in said second plate.
Claim 12
Dependent Claim
21 words
A burner according to claim 1, the profile of the peripheral edge of the opening in said first plate being toothed.
Claim 13
Dependent Claim
21 words
A burner according to claim 1, the profile of the peripheral edge of the opening in said first plate being serrated.
Claim 14
Dependent Claim
53 words
A burner according to claim 1, the opening as formed in said first plate being centrally located therein, said first plate having a plurality of air openings that are positioned around said opening and are positioned within a circular axial projection that is projected from the open upstream end of the mixing tube.
