CHRISTOPHER STBACHAN, OF SOUTH ORANGE, NEW JERSEY, AND DAVID J. IRISH, 0] NEW YORK, N. Y., ASSIGNOBS TO MORSE DRYDOCK & REPAIR 00., OF NEW YORK,
N. Y., A CORPORATION OF NEW YORK.
A'LOMIZEE.
To all whom it may concern:
Be it known that we, CHRISTOPHER Smomn and DAVID J. IRISH, citizens of the United States, residing at South Orange,
in the county of Essex and State of New Jerse and at New York city, in the county of Richmond and State of New York, respectively, have invented certain new and useful Improvements in Atomizers, of which the followin is a specification, reference being had t erein to the accompanying drawin This invention relates to improvements in sprayers or atomizers and more particularly to 011 burnersaused in boiler furnaces and the like, in which the oil is supplied to the burner under ressure and is atomized as it is discharged into the combustion chamber of the furnace.
One object of the invention is to provide a simple, eflicient and comparatively inexpensive mechanical burner or atomizer of this character which has no valve or other movable parts in the burner but in which the size of the preferably cone-shaped spray may be varied or regulated while maintaining proper atomization of the fuel and without changing the pressure of the fuel supplied to the burner, changing the hp or otherwise changing or adjusting any part of the atomizer.
In carryin out the invention, a burner head or nozz e is employed having two or more sets of different sized ports and a common discharge orifice to which all of said ports lead; and a lurality of tubes disposed one within anot er, are employed to supply the oil to said sets of ports, a further aim being to provide novel means for holding the tubes in proper relation and for permitting easy disassembling of the burner, for instance when it is necessary to clean the same.
With the foregoing and other ob]ects in view, the invention resides in the novel subject matter hereinafter described and claimed, the description being supplemented by the accompanying drawing, in which Figure 1 is a longitudinal sectional view of a burner constructed in accordance with my invention, the tangential ports in the head being diagrammatically shown.
- Figure 2 is an enlarged longitudinal sec- Applieation filed November 15, 1922. Serial 1T0. 001,117.
tional view of the burner head or nozzle taken on the line 22 of Fig. 3.
Figure 3 is a vertical transverse section on line 33 of Fig. 1.
In illustrating my invention, we have disclosed one practical form of construction, but it is to be understood that the exact details shown and described, need not be followed in all respects, as the disclosure is for illustrative purposes. only.
The numeral 1 designates a hollow body which is preferably cast in somewhat the form of a pipe fitting, said body being provided with an open end 2, with an internal circumferential rib 3 between its ends, and with oil inlets 4 and 5 at opposite sides of this rib, for communication with oil supply pipes 6 having independent control valves and 8, both of these pipes being adapted to lead to a common means for supplying oil under pressure, such as the usual pumping outfit now used in connection with mechanical oil burners.
An outer tube 9 is threaded or otherwise connected with the open end of the body 1 and an inner tube 10 which is spaced from the tube 9, has a frictional engagement with the inner surface of the rib 3, the front ends of these tubes being closed by a head or nozzle 11 which is by preference of the twoplart construction shown. One part of this ead is shown in the form of a substantially flat disk 12 having a projecting flange 13 which is connected suitably with the inner tube 10, for instance by threading. The peripheral portion of the disk or closure 12 abuts the front end of the outer tube 9 and is held in this position by a cap or tip 14.- which is threaded or otherwise suitably connected with said outer tube. This cap is provided with a central oil discharge orifice 15 whose rear end is enlarged as indicated at 16, forming a chamber between the front and rear sides of the head 11, which chamber is preferably of the conical shape shown. An outer series or group of ports 17 is formed through the closure disk 12 and leads from the outer tube 9 to the chamber 16, while an inner series or grou of ports 18 is also formed through said dis to establish communication between the inner tube 10 and said chamber 16. One group or set of ports has a greater maximum capacity constant pressure on the oil than the other group. In the present showing, the two sets of ports each have all of their ports of a uniform size, although the ports of one set are shown larger than those of the other set. In other words, the total cross-sectional area of the ports 17 has been shown as less than that of the ports 18. The ports of the two groups in the present showing, are tangentially disposed with respect to imaginary circles concentric with the orifice 15 in dotted lines in Fig. 2, whereby to impart a whirling motion to the oil or other fluid as it is discharged into the enlarged end or chamber 16 of the outlet orifice 15, thus causing the discharged spray to be in the form of a hollow cone.
By employing the construction shown or a substantial equivalent thereof, both the quantity of oil supplied to the furnace and the velocity of the spray may be readily controlled and the form of burner head which we have disclosed insures the most thorough atomization which is essential to the best results. It will be seen that with a supplied through the pipes 6, a comparatively large quantity of oil may be sprayed from the burner head when both valves 7 and 8 are opened, as the oil is then supplied under pressure to both tubes 9 and 10, and is discharged through both sets of ports 17 and 18, to the chamber 16 and its orifice 15. By closing the valve 7 which supplies oil to V the outer tube 9, it will be seen that all of the pressure behind the oil is exerted to force it from the inner relatively large ports 18, thereby increasing the velocity .of the discharged spray, While at the same time cutting down the amount of oil sprayed from the burner. By closing the valve 8 which supplies oil to the inner tube 10 and opening the valve 7 so that the full pressure behind the oil will act to discharge oil through the ports 17, the velocity of the spray will be still further increased but the quantity of oil delivered will be reduced since the ports 17 are of less size than the ports 18.
\Vhile we have shown two independently controlled oil or fluid feeds, including the ports 17 and 18 respectively, it will be understood that a greater number may be used, if greaterdiexibility or range of adjustment of the burner or other atomizing device is desired.
By providing an arrangement by means of which the oil may be supplied through any one or more of two or more sets of ports, or simultaneously through all the sets, a burner is provided which may be easily regulated to meet all practical demands; and it will not be necessary to vary the oil pressure, to change the burner tip or to shut off one or more of a series of burners in a boiler furnace in order to get an effective lowered. The use of the control valves in 7 the oil feed pipes obviates the necesity of valves or other movable ports in the atomizer. Attention is further directed to the fact that the construction used is simple and comparatively inexpensive regardless of the fact that it is highly efiicientin operation.
