LIQUIDl-IYDROCARBON BURNER.

SPECIFICATION forming part of Letters Patent No. 252,618, dated January 24, 1882.

Application filed March 22, 1881. (No model.)

To all whom it may concern:

Beit known that I, ALFRED S. MUNGER, of Brooklyn, in thc county ot' Kings and State of New York, have invented an Improvement in Liquid- Hydrocarbon Burners, of which the following is a specification.

This invention comprises a novel combination of parts, whereby is provided a burner for burning naphtha and other like light hydrocarbon oils, which has the merit of providing for an unusually rapid and effective heating without vaporization of the hydrocarbon oil immediately preceding its exit from the tip at which it is ignited, the flame resulting from said ignition being automatically regulated as concerns the iulow of the heated hydrocarbon oil to the tip, and also capable of regulation as concerns the quantity of atmospheric air admitted to the burner during combustion.

Figure 1 is a vertical sectional view, and Fig. 2 a plan view, of an apparatus embracing my said invention.

A is the tip, screwed upon the tubularconnection B, which communicates by a passage, a,with the annular chamber C. The said chamber has its outer walls com posed of a thick casting, A', and its inner walls of a thin wroughtmetal tube, B', the object being to have the outer walls ot' said chamber of such thickness and mass ot' meta-l as to render the transmission of heat therethrough extremely slow and also small in quantity, while the inner wall, B', is ot' such character as to render the transmission of heat through the said inner wall very rapid, facile, and in great quantity. Inasmuch as the inner wall B' is itself ot' annular or,

cylindric form, in order to give the requisite annular shape to the chamber O, it follows that the said tube constitutes a circular passage open at both ends, and in the construction and operation ot' the apparatus the said tube is placed above and substantially axially coincident with the burner A.

In the tubular connection B is provided a suitable valve, D, by which, when required, the interior passage of the said connection B may be closed or may he diminished to any required extent, either to diminish the available crosssection of said interior of the connection B or to entirely close the same to shut oft' communication between the tip A and the annular chamber C.

At that side of the casting A' opposite the passage a, and at thelower end of the annular chamber O, is an inlet-pipe, E, through which the hydrocarbon is admitted to the said antililar chamber C from any suitable source ot' su pply, said source of supply being preferably elevated to a degree sufficient to insure the automatic inflow otl the hydrocarbon through the inlet-pipe E to the annular chamber O, as aforesaid. v l

The upper portion of the burner A is provided with an external screw-thread, upon which is screwed an internal threaded disk, G, in such manner that by turning the said disk in one direction it will be moved upward to diminish the space for the passage of air bess j tween the tip A and the tubular passage formed by the tube orinner walls, B', hereinbefore described, so that by moving the said disk Gr up or down the intlow ot' air to the liame may be regulated at will.

1t will be observed that the passage a connects with the Yannular chamber O at the top ofthe latter, while the inflow-pipe E connects with the said chamber at the bottom thereof'.

The operation ot' the invention is as follows: The liquid naphtha or other liquid hydrocarbon iiows into the chamber G, iilling the same, and passing over into and downward from the passage a, through the hollow interior of the connection B, and thence to the burner A, and out at the upper end or top thereof', where it is ignited, so that the dame and hot products otcombustion pass up into the tubular passage above the same, and finally out at the top of said tubular passage, where they can be utilized for any ot` the purposes to which the tiamc and hot products of combustion are applicable. During the transmission through the said tubular passa ge the heat is readily transmitted through the extremely thin walls B' of the annular chamber C, and thereby raises the temperature.

of the liquid hydrocarbon which iiows through the said annular chamber, as just described, to a degree at which the said hydrocarbon will be most readily ignited and most effectively burned when it issues from the burner A, as hereinbefore explained, so that while the ame and hot products of combustion are caused to act rapidly and effectively upon the hydrocarbon supplied to the burner A the extremely thick walls A', of cast-iron or other compara- IOO tively poor heattransmitting substance, effectively preclude the loss of heat by communicvition from said outer walls. By this means a lnost effective and economical heating of the hydrocarbon is secured, and as a result an unusually intense and smokeless ilame when the said hydrocarbon is consumed at the top of the burner. Furthermore, the inlet E being at the bottom of the annular chamber C, while the passage a communicates with the said chamber C at the top thereof, it follows thatI as the hydrocarbon is expanded in the chamber C a back-pressure against the inlet E is automatically exerted by reason ot' such expansion of the liquid hydrocarbon within the chamber, so that the higher the heat within the said chamber C the more the inflow from the pipe E is hindered; and inasmuch as a less quantity of hydrocarbon is required at a high heat than at a low heat, it follows that an autoinatical regulation of' the inflow of the hydrocarbon with reference to the requirements ot'lhelnirner A is secured.

As hereinbcfore explained, the admission ot' atmospheric air to the tip of the burner is readily regulated by the disk G. In starting the apparatus, however, it is desirable that the burner A should be heated above ordinary temperatures, in order that the hydrocarbon issuing' at its tip may readily ignite. To this end there is provided beneath the said burner A a pan or receptacle, H, which, for conven ience, I designate a Haslrpanl Into this pa. I poura small quantity of theliquid hydrocarbon and ignite the same, whereupon it ashcs up into a momentary but intense dame, which impinges on the burner A and the adjacent portions ofthe connection B to an extent suticient to heat the same, and also any portion of liquid hydrocarbon contained therein, to a degree sutlicient to insure the rapid ignition of the said hydrocarbon at the top of the burner when it is required to put the apparatus in operation.

What I claim as my invention is- An apparatus t'or burning naphtha and like light hydrocarbon oils, composed of the externally-threaded burner A, the annular chamber C. having thick outer walls of cast metal and thin inner walls ofwrought metal, the passage a, connecting with the said chamber at its top, the inlet E, connecting with the said chamber at its bottom, and the internally-tln'caded disk G, the burner and the disk being placed coincident with the passage through the thin internal walls of the chamber C, and the whole being constructed, combined, and arranged substantially as and t'or the purpose herein set t'orth.
