' BURNER.
Specification of Letters Patent.
Patented Apr. 3, 191?.
Application filed March 22, 1916. Serial No. 85,764.
To all whom it may concern:
Be it known that I, JULIUs C. I'ILNZ, a citizen of the United States, and a resident of Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Burners, of which the following is a specification.
The present invention relates to improve ments in burners, and particularly oil burners for use in china and other such kilns, in which an intense and sustained heat may be maintained, and utilized in the most efiective manner.
An object of the invention is to provide such an improved burner in which the vaporous liquid fuel may be preheated and burned in a combined liquid and vaporous state, whereby with the proper admixture of air, the maximum amount of heat may be obtained for a given amount of fuel. An-
other object is to provide draft means by which the heat may be more intensely directed to certain portions of the kiln when it is desirable, because of the placing or character of the china being fired therein. A still further object is to produce a burner in which there will be no danger of explosion.
With these and other objects in view, my invention is shown. in the accompanying drawings, and will be hereinafter more fully described with reference thereto and finally pointed out in the claims.
In the accompanying drawings:
Figure 1 is a plan view of my improved burner,
Fig. 2 is a vertical sectional view thereof on the line 22 of Fig. 1, and
Fig. 3 is a similar view taken on the line 33 of Fig. 1.
Similar reference characters indicate corresponding parts throughout the several figures of the drawings.
Referring to the drawings, my invention comprises an annular burner ring 10, disposed upon lugs 11, provided on the interior of the burner casing 12, and supported upon legs 13 extending upwardly from an annular ash pit 14. A depending reservoir 15 is formed interiorly of the annular burner ring, the inner wall 16 of which extends to a point substantially in the same horizontal plane as the upper surface of the burner ring. Centrally the burner is open as at 17 forming a direct passage for air flowing through the central opening 18 of the ash pit, and also communicates with air entering beneath the burner, as clearly indicated by the arrows. Kerosene or other suitable oil is fed to the annular channel of the burner ring by a plurality of inlet pipes 19, the inlet ports 20 of the burner ring being of a diameter less than the diameter of the said channel. A further supply of air enters the burner surrounding the feed pipe as indicated by the arrows. There are provided on the inner wall of the ring burner 10, a plurality of passages 21, of substantially the same diameter as the inlet ports, the axes of the said passages, the inlet ports, and the channel of the burner being substantially in the same horizontal plane. Any oil it will be seen entering the inlet ports of the burner in excess of that caught in the lower portion of the channel will overflow into the annular reservoir 15, where it is absorbed by a filling of asbestos 22, which acts inthe nature of a wick. Circumferentially of the inner top portion of the burner ring, there are provided a plurality of inwardly and upwardly inclined jets 23.
The wall of the casing 12 opposite the burner ring 10 is inclined inwardly and upwardly as at 2 and the upper contracted portion 25 is provided on three sides with draft openings 26, which are controlled by gates 27 disposed exteriorly of the casing, and hinged above the openings by hinges 28 and 29. A lever 30 is provided on the gates, having on its inner end a curved ratchet blade 31 adapted to engage a lug 32 on the lower wall of the opening and hold the gate in difiTerent positions of adjustment. At the other side of the casing the walls are formed parallel as at 33, and a hinged door 34 is provided at the forward edge thereof. By reason of the inclination of the draft gates and the comparatively large surface presented thereby the draft'entering the burner is directed in a substantially diagonal path across the kiln as shown by the arrows, and in this way the intensity of the heat may be concentrated upon any particular portion of the kiln desired. A circumferential flange 35 is provided on the upper edge of the easing to which the body of the kiln is attached, as is well known.
The operation of my improved burner is as follows:
The kerosene entering the inlet ports settles in the lower portion of the channel of the burner ring, and the excess overflows into the annular reservoir where it is absorbed by the asbestos contained therein. The initial heat produced upon igniting the oil in the reservoir preheats the oil flowing through the burner ring before it enters the reservoir, and also causes a vaporization of the oil, the gases passing upwardly and out of the jets 23 where they are ignited. Air is supplied to the flame both above and below the burner as clearly indicated.by the arrows. An intense and accurately controllable heat of from 2,60O to 2,700 F. is produced in this manner, and as a result the china or other ware in the kiln may be effectively and perfectly fired.
Because all of the gas is taken off and ignited as it generates, there can be no danger of an explosion. There is no carboni- Zation, and consequently no soot is formed.
I have illustrated a preferred and satisfactory form of my invention, but it is obvious that changes may be made therein, within the spirit and scope thereof, as defined in the appended claims.
- I claim: a
1. A duplex burner for hydrocarbon liquids comprising a vapo-rburner consisting of a horizontal tube having a series of vapor jets in its upper portion and an outlet port disposed below said burner jets and above the bottom of said tube, and an oil burner disposed adjacent to said vapor burner and adapted to receive the overflow thereof through said outlet port, said duplex burner being adapted to burn vapor and oil simultaneously, the oil burner serving to heat the vapor burner and vaporize more or less of the oil contained therein.
2. A duplex burner for hydrocarbon liquids comprising a central air flue, an oil burner surrounding said air flue, and a horizontal vapor burner surrounding the upper part of said oil burner and provided with a series of vapor jets in its upper portion and with a series of outlet ports disposed below said jets and above the bottom of said vapor burner and adapted to feed oil from said vapor burner to said oil burner.
3. A duplex burner for hydrocarbon liquids comprising a central air flue, an annular oil burner surrounding said air flue, and a horizontal annular vapor burner surrounding the upper part of said oil burner and provided with a series of vapor jets in its upper portion and with a series of outlet ports disposed below said jets and above the bottom of said vapor burner and adapted to feed oil from said vapor burner to said oil burner.
4. A duplex burner for hydrocarbon liquids consisting of an integral casting comprising a central air flue, an oil burner surrounding said air flue, a horizontal vapor burner surrounding the upper part of said oil burner and provided with a series of vapor jets in its upper portion and with a series of outlet ports disposed below said jets and above the bottom of said vapor burner and adapted to feed oil from said vapor burner to said oil burner, and supporting lugs on said vapor burner.
In testimony, that I claim the foregoing as my invention, I have signed my name in presence of two subscribing witnesses.
