HYDROGABBON-BURNER.
Specification of Letters Patent.
Patented May 1920.
Application filed November 26, 1919. Serial No; 34057 65:
' a new and improved hydrocarbon burner arranged to lnsure a thorough atomlzing of the crude oil or other liquid hydrocarbon fuel and to produce an effective mixing of the air and the atomized fuel to insure com plete combustion thereby utilizing the liquid fuel to the fullest advantage.
Another object is to insure the formation of a conical shaped flame.
Another object is to provide a hydrocarbon burner which is simple and durable in construction and composed of comparatively few parts, not liable to become disarranged during the use of the burner or by the heat incident to the burning fuel.
With these and other objects in view, the invention consists of certain novel features of construtcion as hereinafter shown and described and then specifically pointed out in the claims.
A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.
Figure 1 is a longitudinal central section of the improved hydrocarbon burner, the section being on the line 1-1 of Fig. 2;
Fig.2 is a cross section of the-same on the line 2-2 of Fig. 1; and
F ig 3 is a similar view of the same on the line 3-3 of Fig. 1.
()n a suitably constructed frame is mounted a motor 11, of any approved construction,'and having its hollow shaft'12 connected by a coupling 13 with a hollow shaft let journaled in bearings 15 and 16, of which the bearing 15 is arranged in the inlet 17 of the casing 18 of a fan or a blower having its rotor 19 secured to the shaft 1 1. The fan casing 18 is attached to the frame 10. The central outlet 20 of the fan casing 18 is provided with a tube 21 supporting at its forward end a nozzle 25 which supports the bearing 16 of the shaft 14:. The latter extends centrally into the nozzle 25, and on the forward end of the shaft is secured a centrifugal atomizer in the form of a cup, forming withthe nozzle 25 an annular air passage 31. Into the atomizer- 30 discharges the forward endof a liquid fuel supply pipe 32 which extends through the hollow shafts liand 12 and connects with a supply pipe 33 extending from a tank or reservoir containing crude oil or other liquid fuel. The amount of liquid'fuel passing to the pipe 32 is controlled by a suitable needle valve 34 arranged at the junction of the pipes 32 and33.
The back of the atomizer 30' is provided with an auxiliary fan 40, the blades of which coact with the rear wall of the nozzle 25, and this auxiliary fan receives the compressed air discharged by the main fan 19 and increases the pressure of this air and discharges the air through the annular pas sage 31 from the moutlrof-the nozzle located slightly in the rear of the front end of the atomizer 30, as plainly shown in Fig. 1.
It is understood that when the motor 11 is running, the atomizer 30 and the fans 19 and 40 are rotated inunison, and the liquid fuel passing from the supply pipe 32 into the atomizer 30 is thrown outwardly by centrifugal force from the'forward end of the atomizer and there commingles with the compressed air passingout of'the forward end of the nozzle 25. The compressed air deflects the atomized fuel'and thoroughly commingles with the same to form a highly inflammable mixture to be burned in the furnace. It is also understood that the centrifugal action of the atomizer 30 is sufficiently great to insure a thorough atomizing of the liquid fuel, and "the atomized fuel effectively cOmmingles with the air under pressure discharged from the nozzle 25. It will further be noticed that by mounting the atomizer 30 and both fears 19 and 40 on the same shaft 14 a very "simple construction is provided and one not liable to get easily out of order. By providing two fans 19 and 40 the desired air pressure is obtained without providing an unduly large single fan. In this connection it is under stood that in practice the second fan 4:0 raises the air pressure about one ounce above the pressure obtained from the fan 19. by arranging the cup-shaped atomizer 30 and the nozzle 25 in the manner described, the inflammable mixture formed provides a courcally shaped flame.
In order to insure the combustion of the fas plainly shown in (is provided with an air entrance chamber whirling mo the "inflammable 'mlXtllle' the chamber 53- to-the casing 51 a 53 of ring shape and open at its peripheral face. In this chamber 53 arearranged vanes'54: which give the air passing through rotary or mixing it with formed by the tion, thereby A compressed air and the atomized fuel which fis's'ues I 7 '30, as above explained. In the rear from the nozzle 25 and the atomizer of the chamber, 53fis 'arran'ged'a shutter 60 adapted' to be moved forward or backward to j decrease or, increase the amount of air passing from the entrance chamber 53 by way of the vanes 5A into the casing 51. The shutter 60 is attached to-two horizontally extending rods 61 mounted toslide in suit- 3 able bearings 62 (see Fig 2), arranged on Ivided with racks mesh-with segmental gear wheels 6e secured on a transversely extending shaft '65 jourthe frame 1 O,'-'andthesaid rods 61 are'pro- 63 (see Figs.
naledin bearings 66- mounted on the frame "10." A handle 7 O is attached to to permit the operator to turn the shaft 65 the shaft 65 with a view'lto cause the segmental gear wheels 6a to actuate theracks 63- and con- 1 sequently the rod 61 whereby the shutter 60 is moved forward or -backwardaccording to the direction in which the handle 70 is moved at the ti'mer The'chamber 53 is preferablyconnected by a hinge 80'with' a easing "51-"aiid-*the 'frame 10 is preferably at parts supported to move the nozzle 25 and the atomizer, 3O
