Abstract
Abstract An oil burner for oil wells in which the oil to be eliminated is admitted to a specially designed sprayer in which its mechanical atomization is brought about by the construction of said sprayer and its pneumatic atomization is effected by means of inputting gas or air under pressure, the atomized product being ignited by means of spark ignitors and the flame produced being protected by a cylindrical casing. Said casing is provided with a front spray ring which injects water into the flame so as to eliminate the formation of black smoke, and a back spray ring for forming a water curtain which protects the platform against heat radiation from the flame. Said burner is mounted on a tubular support permitting its rotation so as to accompany the wind direction. The material combustion capacity of said burner can reach 30 cubic meters an hour, and for higher flow rates, various identical units can be coupled in parallel.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
250 words
An oil burner for oil wells including a sprayer for atomizing oil products to be burned and means for igniting the atomizedd oil products at the outlet of the sprayer, comprising: a. a housing defining a chamber, b. a turbine mounted within the housing and having a plurality of generally helical channels which communicate a first part of said chamber on one side of the turbine with a second, central part of said chamber adjacent the other side of said turbine, c. an intermediate disc member mounted within the housing adjacent said other side of said turbine, said disc member having a central orifice in communication with said central part of said chamber, d. a centripetal stator mounted within the housing and having a central outlet orifice for the atomized oil products, said outlet orifice being in communication with the central orifice in said intermediate disc and defining a mixing chamber therebetween, e. an inlet for the oil products in the housing communicating with the first part of said chamber, said inlet being non-radial with respect to the housing, f. an inlet for an atomizing gas communicating with said mixing chamber, g. an open ended flame protector casing mounted in front of the sprayer outlet such that a flame produced by combusting atomized oil products is directed along the axis of said flame protector casing, and h. a pair of rings individually mounted at each end of said flame protector casing, each ring having a plurality of water spray nozzles.
Claim 2
Dependent Claim
250 words
An oil burner for oil wells including a sprayer for atomizing oil products to be burned and means for igniting the atomizedd oil products at the outlet of the sprayer, comprising: a. a housing defining a chamber, b. a turbine mounted within the housing and having a plurality of generally helical channels which communicate a first part of said chamber on one side of the turbine with a second, central part of said chamber adjacent the other side of said turbine, c. an intermediate disc member mounted within the housing adjacent said other side of said turbine, said disc member having a central orifice in communication with said central part of said chamber, d. a centripetal stator mounted within the housing and having a central outlet orifice for the atomized oil products, said outlet orifice being in communication with the central orifice in said intermediate disc and defining a mixing chamber therebetween, e. an inlet for the oil products in the housing communicating with the first part of said chamber, said inlet being non-radial with respect to the housing, f. an inlet for an atomizing gas communicating with said mixing chamber, g. an open ended flame protector casing mounted in front of the sprayer outlet such that a flame produced by combusting atomized oil products is directed along the axis of said flame protector casing, and h. a pair of rings individually mounted at each end of said flame protector casing, each ring having a plurality of water spray nozzles.
Claim 3
Dependent Claim
60 words
An oil burner according to claim 1 wherein said turbine is provided with a central bore into which said generally helical channels open, and further comprising a piston within said housing adapted for axial displacement within said central bore, an operating rod for said piston, and a back closure for said housing, said operating rod passing through said back closure.
Claim 4
Dependent Claim
36 words
An oil burner according to claim 1 wherein a first surface of said stator faces said intermediate disk and is provided with radially converging channels for communicating between said atomizing gas inlet and said mixing chamber.
Claim 5
Dependent Claim
33 words
An oil burner according to claim 1 wherein said spray nozzles at that end of said flame protector casing which is adjacent to said sprayer outlet are outwardly directed away from said sprayer.
Claim 6
Dependent Claim
52 words
An oil burner according to claim 1 wherein said spray nozzles at that end of said flame protector casing remote from said sprayer outlet are inclined inwardly in the direction of flame propagation, the axis of each of said spray nozzles forming an angle of less than 20° with the flame axis.
Claim 7
Dependent Claim
52 words
An oil burner according to claim 4 wherein said spray nozzles at that end of said flame protector casing remote from said sprayer outlet are inclined inwardly in the direction of flame propagation, the axis of each of said spray nozzles forming an angle of less than 20° with the flame axis.
Claim 8
Dependent Claim
29 words
An oil burner according to claim 1 further comprising a common feed water pipe interconnecting said spray nozzle rings and feeding said rings from the same water supply source.
Claim 9
Dependent Claim
36 words
An oil burner according to claim 1 further comprising an ignition system for igniting the atomized oil products emerging from said central outlet orifice, said ignition system comprising an electric spark igniter and pilot flame igniters.
Claim 10
Dependent Claim
21 words
An oil burner according to claim 1 wherein said burner is mounted on a support which permits its rotation through 180°.
Claim 11
Dependent Claim
31 words
An oil burner according to claim 1 wherein a water inlet, the atomizing gas inlet and the oil products inlet are provided with rotary joints at the connections with said burner.
Claim 12
Dependent Claim
22 words
An oil burner according to claim 9 further comprising a remote control device for effecting rotation of said burner on said support.
Claim 13
Dependent Claim
159 words
An oil burner according to claim 1 wherein said turbine is provided with a central bore into which said generally helical channels open, a first surface of said stator faces said intermediate disc and is provided with radially converging channels for communicating between said atomizing gas inlet and said mixing chamber, said spray nozzles at that end of said flame protector casing which is adjacent to said sprayer outlet being outwardly directed away from said sprayer, and said spray nozzles at the end of said flame protector casing remote from said sprayer outlet being inclined inwardly in the direction of flame propagation, the axis of each of said inwardly inclined spray nozzles forming an angle of less than 20° with the flame axis, and further comprising a support for said burner permitting the rotation thereof through 180°, and an electric spark igniter and pilot flame igniters positioned to ignite the atomized oil products emerging from said central outlet orifice.
