Abstract
Abstract A burner nozzle providing substantially smokeless combustion of inflamable fluids such as petroleum that must be burned off, in a burner system not requiring water spray. A compressed gas, introduced to the inflamable fluid within the nozzle structure acts as an atomization aid, and as an initial combustion sustaining vehicle for the inflamable fluid. The compressed gas is directively introduced within the nozzle so as to, with combined flow from the nozzle, achieve an optimum flame shape and insure clean burning.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
163 words
A burner nozzle assembly including: a first hollow elongated body; a second hollow elongated body internal to said first body and spaced from said first body to form an annular space therebetween; said second body having a plurality of openings therethrough near one end thereof providing fluid communication between said annular space and the interior of said second body; a member capping said annular space at said one end; deflector means positioned inside said second body in the vicinity of said openings; a plate member positioned intermediate said first body and said, second body, said plate member having a plurality of openings therethrough, each of said openings being angularly directed tangentially to an internal surface of said second body and outward from said first body to said second body; and said deflector means comprising a stem portion and a flanged head portion mounted on one end of said stem portion, the other end of said stem portion being connected to said plate member.
Claim 2
Dependent Claim
163 words
A burner nozzle assembly including: a first hollow elongated body; a second hollow elongated body internal to said first body and spaced from said first body to form an annular space therebetween; said second body having a plurality of openings therethrough near one end thereof providing fluid communication between said annular space and the interior of said second body; a member capping said annular space at said one end; deflector means positioned inside said second body in the vicinity of said openings; a plate member positioned intermediate said first body and said, second body, said plate member having a plurality of openings therethrough, each of said openings being angularly directed tangentially to an internal surface of said second body and outward from said first body to said second body; and said deflector means comprising a stem portion and a flanged head portion mounted on one end of said stem portion, the other end of said stem portion being connected to said plate member.
Claim 3
Dependent Claim
17 words
The burner nozzle assembly of claim 1, wherein said capping member has a plurality of openings therethrough.
Claim 4
Dependent Claim
23 words
The burner nozzle assembly of claim 1, wherein said second body openings are directed tangentially to the inner surface of said second body.
Claim 5
Dependent Claim
221 words
A burner nozzle assembly for mixing a liquid fuel with a combustion supporting gas and discharging the mixture into a flame area including: a first hollow elongated body adapted to carry said fuel; a second hollow elongated body external to and concentric with said first body and spaced therefrom so as to form an annular space therebetween adapted to carry said gas at an elevated pressure; a third hollow body coupled to said first body, said third body being inside said second body and spaced therefrom so as to form an extension of said annular space, said third body having a plurality of openings therethrough for communication of said gas from said annular space extension to the inside of said third body; a plate member positioned intermediate said first body and said third body, said plate member having a plurality of openings therethrough, each of said openings being angularly directed tangentially to an internal surface of said third body and outward from said first body to said third body, whereby a swirling motion is imparted to the fuel as it enters the interior of said body; and a deflector member positioned inside said third body for directing the flow of the fuel to the inner surface of said third body; whereby a mixture of said fuel and said gas is produced.
Claim 6
Dependent Claim
221 words
A burner nozzle assembly for mixing a liquid fuel with a combustion supporting gas and discharging the mixture into a flame area including: a first hollow elongated body adapted to carry said fuel; a second hollow elongated body external to and concentric with said first body and spaced therefrom so as to form an annular space therebetween adapted to carry said gas at an elevated pressure; a third hollow body coupled to said first body, said third body being inside said second body and spaced therefrom so as to form an extension of said annular space, said third body having a plurality of openings therethrough for communication of said gas from said annular space extension to the inside of said third body; a plate member positioned intermediate said first body and said third body, said plate member having a plurality of openings therethrough, each of said openings being angularly directed tangentially to an internal surface of said third body and outward from said first body to said third body, whereby a swirling motion is imparted to the fuel as it enters the interior of said body; and a deflector member positioned inside said third body for directing the flow of the fuel to the inner surface of said third body; whereby a mixture of said fuel and said gas is produced.
Claim 7
Dependent Claim
35 words
The burner nozzle of claim 4, wherein said third body openings are directed tangentially to the inner surface of said third body, whereby a swirling motion is imparted to the mixture of fuel and gas.
Claim 8
Dependent Claim
41 words
The burner nozzle assembly of claim 4, wherein said deflector member comprises a stem portion and a flanged head portion mounted on one end of said stem portion, the other end of said stem portion being connected to said plate member.
Claim 9
Dependent Claim
51 words
The burner nozzle assembly of claim 6, wherein the inner surface of said third body is slanted in the vicinity of said stem portion of said deflector member so as to direct the swirling fuel around said stem portion to fuel impact on said flanged head portion of said deflector member.
Claim 10
Dependent Claim
64 words
The burner nozzle assembly of claim 4, further comprising a member capping said annular space extension, said capping member having a plurality of openings therethrough, each of said openings being angularly directed tangentially to said third body and inward from said annular space extension, whereby a swirling motion is imparted to the gas as it exits said burner nozzle assembly into said flame area.
