oil into a spray, by atomization prior to mixing the same with air or other gas. A further object is to provide means for insuring positive and even feed of the hydrocarbon liquid to a spraying nozzle. A further object isfto provide means for eliminating what is known as the blackspot in in the flame of a burner. A further object is to provide a mechanism that will atomize oil or other liquids and mix the atomized liquid with air or other gases in such manner as to derive the highest efiiciency in the consumption of the mixture.
The invention will be hereinafter fully set forth and particularly pointed out in the claims.
In the accompanying drawing:
Figure 1 is a side elevation partly in section illustrating a burner constructed in accordance with the invention.- .Figure 2 is an enlarged end view ofthe pump mechanism. Figures 3 and 4 are detail views illustrating the spray nozzle.
Referring to the drawing, I0 designates an electric motor of any preferred construction, supported upon a suitable base and provided with the usual armature shaft II. g
Mounted on the shaft II so as to rotate therewith, is the driving-gear-impeller member I3 of a gear pump P, said gear impeller member being mounted within a suitable pump casing located adjacent to the motor. The gear impeller meml ber I3 meshes with a smaller driven-gear-impeller member I4 withinl the pump.casing, and the latter is provided with an inlet port I5 and an outlet port I6. The inlet opening I5 is connected with a source of fuel supply (not shown) by a conduit |55.
The pump gear impeller member Ill is mounted upon a tubular shaft I1 in such manner as to rotate therewith, and so that the shaft I'I may be driven by the said member i4. Said tubular shaft I1 is rotatably mounted in bearing I8 formed on the pump casing and a bearing I9 resting upon the base 20 which also supports the pump casing. It will be noted that the gear-impeller members I3 and I4 are of different diameters, so as to increase the number of rotations of the smaller gear impeller member, although the peripheral speed of the two gears will remain the same, whereby the pumping func-tions are in no way impaired. i
It will be noted that the shaft I'I is provided with alongitudinal bore 25, and that the rear end of said shaft, i. e. thesleft end as illustrated in Figure l, is enclosed by a casing 22, removably secured to the pump casing, and provided with an oil inlet opening 23, which is connected with the outlet opening IB of the pump by means of a conduit Ilia. The rear end of the shaft I1 extends into thel chamber 22 in such manner that fuel oil forced by the pump through the conduit llia will enter and flow through the chamber 22, and into the rear end of the bore 25. The fuel intake pipe I5n is connected by means of a bypass conduit 24 with the chamber 22, so that any excess fuel oil will circulate through the chamber 22 and back to the fuel inlet pipe |511.
The motor I0 is connected with asuitable 'source of electrical energy (not shown) in any well known manner, and its operation controlled by suitable rheostats which Vit is deemed unnecessary to'illustrate. Located above the motor is a transformer T,. whichl isconnected by suitable electrical leads 26, with oneor more electrical ignition devices 21, which extend into the combustion chamber C.
The shaft Il is provided with an` axial exten,- sion Ila, the outer free end of which is located within the'combustion chamber C, at a position adjacent to the ignition devices 2'I.l The outer free end of the conduit extension is covered by a closure member secured thereto in suitablemanner, said closure member, having a wall which extends across the open end of the conduit. Said wall is provided with a minute discharge orice which is radially spaced from the normal axial center of the bore 25, and located at such a position that; a gyratory movement will be imparted to the liquid discharged through the orifice dur ing rotation of the conduit, said gyratory effect being obtained by reason of `the orbital travel of the orifice around said axial center.
Mounted upon the shaft I1 by means of a suitable hub 30 is a fan 30, which is located within a blower casing 3l, and provided with van'es 32 arranged parallel with the axis ofthe shaft I1,
but of concave-convex form and so arranged as to draw atmospheric air through the inlet openl ing 33 and to propel it through the air supply casing 3|. The diameter of the blower 32 is greater than the diameter of the driven. gear I4,
' and therefore the peripheral speed of the fan will be correspondingly greater than the peripheral speed of the gears, wherby air is supplied from the blower to the mixing` means faster than the hydrocarbon liquid is supplied to said mixingv means, so that the desired proportions of air and hydrocarbon are maintained. Said casing is provided with a channel of annular cross section and increasing diameter, produced by a conically' shaped interior wall 34. The air is directed through a pipe 35 into the mixing chamber M, said .pipe being of smaller diameter than said mixing chamber so Vas to provide a surrounding annular space 3B, through which additional atmospheric air may enter said chamber. The mixingA chamber M discharges into a combustion chamber C, which is lined in suitable manner.
The heat produced by the combustion maybe utilized in any desired manner. In operation, the motor I0 causes a rotation of the shaft and its extension |18, and with it a concurrent rotation of the gear-impellei; member I4.- As the pump P operates the oil or other liquid is delivered to thechamber 22, and from thence is forced into vthe rear open end of the bore 25.
The structure of the pump is such that a uniform pressure is maintained upon the oil as it flows through the bore and is discharged through the opening in the nozzle 28. The arrangement of the gears I3 and I4 is such as to increase the number of revolutions per minute of shaft I1 as compared to those of shaft Il. The high speed rotation of the shaft I1 and its extension-l1",
together with the offset position of the discharge opening 29 of the nozzle 28 serves to scatter the atomzed liquid by. a gyratory motion. Simul which does not fan out, and mixing of the fuel accessi fuel stream is prevented. The arrangement also is-such that the walls of the re chamber become and remain red hot, and the reflected heat produces a more combustible mixture than would be possible if the vapor is allowed to impinge on the sides of the fire chamber. If desired, the operation may be controlled in a well known manner through the medium of thermostatic devices which are so well known in the art that illustration thereof is deemed unnecessary. An important advantage is that the ratio of the gears of the pump may bev so designed as tc impart a desired speed of rotation to the blower so as to adequately supply the volume of air rewith the air driven through the mixing chamber is much more complete and effective than is possible by means of a fixed nozzle. In other words, although the orifice of the nozzle is in an approximately fixedl position, the discharge therefrom is of a gyratory nature. Thus, it is possible to produce a flame of extreme length but of small diameter. Obviously, the distance and direction off-center of the orifice and the longitudinal bore, are important factors .in controlling the outside diameter of the ame.
An important advantage `of the invention is that in operation there is no impinging of raw vapor on the sides of the fire chamber, so that formation of carbon through the chilling of. the
quired for perfect combustion.
Having thus explained the nature of the inventionand described an operative manner of constructing and using the same, although without attempting to set forth all of the forms in which it may be made, or all of the forms of its use, what is claimed is:
1. An oil burner comprising a rotatively mounted tubular shaft having a receiving end and a delivery end, a discharge nozzle on said delivery end, a gear pump having two intermeshing gear-impeller members of different diame'- ters, the gear-impeller member of smaller diameter being secured to said shaft, a supply pipe connecting the delivery side of said pump to the receiving end of said shaft, power means operating` independently of the tubular shaft for rotating the larger driving-gear-impeller member, whereby oil is fed to the tubular shaft simultaneously with the rotation of the latter, and a fan secured to and rotatable with said shaft at a position' between the pump and the nozzle. g
2. An oil burner comprising a rotatively mounted tubular shaft having a receiving end and a delivery end, a nozzle on said delivery end having a single discharge orifice spaced radially with respect to the axis of the shaft, a gear .pump
operative` independently of the tubular shaft for rotating the larger gear-lmpeller member, whereby oilis fed to the tubular shaft simultaneously with the rotation of the latter, and a fan secured to and rotatable with said shaft at a position .between'the pump and the nozzle.
