HYDROCARBON-BURNER.
SPECEFIGATION forming part of Letters Patent No. 680,573, dated August 13, 1901.
Application tiled December 28, 1900. Serial No. 41,377. (No model.)
To all whom it may concern.-
Be it known that I, JOSEPH EAsTWooD, a citizen of the United States, residing in the city and county ot' San Francisco and State of California, have invented certain new and useful Improvements in Hydrocarbon-Burners; and I do hereby declare the following to be a full, clear, and exact description of the same.
My invention relates to that class of hydrocarbon-burners in which both air and steam are employed.
It consists in the relative arrangement of the several passages and their connections, which I shall hereinafter describe.
The object of my invention is to provide a simple and eicctive burner of this class wherein the oil is prepared by the proper mingling of the steam therewith for the addition of the air at the moment of the exit of all three Iluids from the burner.
A further object is torprovide an arrangement which shall enable the air as it passes through the burner to the point where it mingles with the oil and steam to serve as a jacket to protect the parts of the burn er from undue heat.
Referring to the accompanying drawings, Figure l is a longitudinal section of my burner. Fig. 2 is a front View of its exit end.
A is a pipe forming a passage into the rear end of which, by means of a suitable connection, the oil-pipe B is adapted to feed the oil. Into said rear end the steam-pipe C, by means of a suitable connection, is adapted to deliver steam, which mixes with the oil, and both are forced forward through said pipe or passageA to its contracted exit c. Around pipe A is a pipe D of sufficiently greater diameter to leave an annular passage d. Into the rear end of this passage d, by means of a suitable connection, the air-pipe E is adapted to deliver air. As will be seen, the pipe D has a length sufcient to cause the annular airpassage d to extend to and terminate substantially in the plane ofthe exit a of passage A. In practice the oil, steam, and air are supplied under pressure, each being separately controlled by a suitable cock, as shown. This control enables the operator to supply more or less steam or air, according to the degree of heat required or the place of its application. Thus by increasing the steam the flame may be lengthened to apply the heat at a desired point, and by increasing the air the greatest heat may be had close to the exit of the burner. As the air is mingled with the oil and steam only at the exit of the latter,thelongcircumscribing passage d through which it iiows enables it to serve as a jacketprotector for the inner pipe, through which the oil and steam pass, thereby keeping the latter from getting too hot; and, further, the air also protects the outer pipe from undue heat, and as said pipe is no longer than the inner pipe the outer pipe is protected throughout its entire length and will not melt away, aswould be the case if it projected beyond the exit of the oil and steam. The burner is thus prevented from getting hot. The oil and steam are Well mixed in the inner passage and are ready at their exit for the air which is supplied from the surrounding airpassage. v
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
l. In a hydrocarbon-burner, the combination of an inner tube open at its rear end, an oil-supply nozzle directed axially into the extreme rear open end of said tube, of a size to leave a passage between the same and the walls of the tube, a chamber connected to the rear end of said tube, a steam-supply entering said chamber directly in rear of said oilnozzle and in line therewith, a tube surrounding said inner tube and connecting at its rear with an air-supply, said surrounding tube being so disposed as to deliver air into the mingled oil and steam as they issue from the inner tube, substantially as described.
2. In a hydrocarbon-burner, the combination of an inner tube open at its rear end, a chamber connected to the rear end of said tube, an oil-nozzle connected with an oil-supply and projecting axially into and terminating in the eXtreme rear open end of said tube, of a size to leave a passage between the same and the walls of the tube, a steam-nozzle entering said chamber axially in rear of and in line with said oil-nozzle, a chamber surrounding said inner tube at the rear, an air-supply connected therewith, and an outer tube connected to said surrounding chamber and sur- IOO said inner tube, a second chamber surrounding and secured to said tube and separated from said irstmentioned chamber with which second chamber said outer tube connects, and an air-supply pipe connecting with said seoond chamber, substantially as described.
In witness whereofl have hereunto set my hand.
