LIQUID FUEL BURNER Filed Oct. 27, 1952 Patented Feb. 2, 1954 LIQUID FUEL BURNER Richard H. Pardee and Robert J. Strawn, Jr., La Junta, 0010.
Application October 27, 1952, Serial No. 317,019
3 Claims.
This invention relates to a liquid fuel burner, and more particularly to a burner designed for use with liquid propane and similar liquid gases for throwing a fiame for use in weed burning.
The principal object of the invention is to provide an exceedingly simple burner construction which will efiiciently vaporize and gasify liquid fuels such as propane and butane, and which will completely burn the fuel to produce an exceedingly hot high velocity flame.
Another object of the invention is to provide a burner for weed. burning purposes that will be light in weight, so as to be easily portable.
Other objects and advantages reside in the detail construction of the invention, which is designed for simplicity, economy, and efficiency. These will become more apparent from the following description.
In the following detailed description of the invention, reference is had to the accompanying drawing which forms a part hereof. Like numerals refer to like parts in all views of the drawing and throughout the description.
In the drawing:
Fig. 1 is a side view of the improved burner;
Figs. 2 and 3 are enlarged cross-sections through the burner, taken on the lines 2-2 and 3-3, respectively, Fig. 1;
Fig. 4 is a longitudinal section through the burner on the original scale, taken on the line l--4, Fig. 3;
Fig. 5 is an enlarged, detail section through the forward upper peripheral edge of the burner taken on the line 4-4, Fig. 3; and
Fig. 6 is a detail, longitudinal, sectional view through a fuel orifice bushing employed in the improved burner.
The improved burner comprises an elongated tubular combustion chamber Ill having an open forward extremity. The rear extremity of the combustion chamber is closed by an annular end plate II. A tubular fuel expansion chamber l2 communicates concentrically through the end plate H in axial alignment with the chamber Hi. The forward extremity of the expansion chamber I2 is open to the combustion chamber I 0, and the rear extremity of the former is closed by a circular end plate I 3.
A vaporizing jacket I4 surrounds the forward extremity of the combustion chamber Ill. The .iacket I6 is enclosed in a cylindrical outer housing I5 which is uniformly spaced from the wall of the chamber Ill. The rear extremity of the jacket I4 is closed by an annular rear wall 16, and the forward extremity thereof is closedby a circular pipe ring l1, Welded or otherwise secured therein to seal the vaporizing 'jacket l4.
Liquid fuel, such as liquid propane, is conducted to the pipe ring IT by means of a feed pipe l8 extending through the rear wall I6 of the housing I 5 and terminating at its forward extremity incommunication with the pipe ring of fuel discharging from the perforations 20 will be directed at aninward angle against the wall of the combustion chamber ID, as shown in Fig. 5.-
Vapor is conducted from the jacket It. by.
means of a hook-shaped vapor pipe 2|. which communicates through the rear wall l6 of the housing l5 and extends rearwardly to a hookshaped extremity 22. The latter extremity curves inwardly through the end plate l3 where it is sealed into a coupling sleeve 23 welded or otherwise mounted in the latter plate.
A threaded jet bushing 24 is threaded into the inner extremity of the coupling sleeve 23. The inner extremity of the jet bushing 24 is closed, and the closure is perforated by means of an angularly positioned fuel orifice 25 which enters at an acute angle to the axis of the latter so that vapors and gases discharging from the orifice 25 will be directed on a spiral path against the wall of the expansion chamber [2.
Primary air enters the combustion chamber Hi through a plurality of air openings 26 pcsitioned in and adjacent the end plate I I, and secondary air enters the combustion chamber through a plurality of similar openings 21 pcsitioned forwardly of the openings 26. The air openings are carefully predetermined as to area to obtain the most efficient combustion.
In use, a liquid fuel hose is connected to the coupling [9. The fuel feeds into the pipe ring I! and discharges from the latter in a plurality of jet-like streams directed inwardly against the hot wall of the combustion chamber m. The heat of the latter immediately vaporizes and gasifies the fuel, creating a pressure in the jacket It. This pressure forces the vaporized fuel through the vapor pi e 2! and discharges it from the orifice Jet 25 at exceedingly high velocity on a whirling, angular spiral path.
The rearward extremity of the feed pipe- I8 is spaced from the wall of the combustion the burner to the supporting bars of railway' burner cars and other carrying vehicles. No: pumps or compressors are necessary with the improved burner, since the pressure generated in" the chamber I4 is sufficient for complete burner operation. 7 p
The combustion chamber 10 may be strengthened and stifiened from the outer housing l'5- by means of suitable spacer. members 28 welded or otherwise mounted. the vaporizing; jacket; 154.. While a specificform of the; improvement. has been described and illustrated hereim, it to be understood that the same maybe varied-,. within the scope of the appended claims, without departingfrom the-spirit of the invention.
1 Having thus described. the: invention; what claimed and desired secured by Letters Patent 1'. A liquid hydrocarbon fuel burner compris-- ing: a. tubular combustion chamber having an open forward extremity; an annular end. plate closing thefrearward' extremity of said chamber; a: tubular expansion" chamber of smaller diameter than said combustion chamber communicating centrally through said end. plate and extending rearwardlyin axial alignment with said' combustion chamber; a rear end plate closing the rear extremity of said expansion chamber; a sealed, annular vaporizing jacket surrounding theforward extremity of said. combustion chamber; a
pipe ring closing the forward extremity of said jacket; an annular ring plate closing the rear extremity of said jacket; a fuel feed pipe extending forwardly through said ring plate and terminating in communication with said pipe ring, said pipe ring having spaced perforations communicating with said vaporizing jacket; a vapor pipe communicating through the ring plate with the vaporizing jacket and extending rearwardly beyond said expansion chamber, thence forwardly to communicate through the rear wall of the latter chamber; an orifice member mounted in the rearwall of said expansion chamber in communication with said vapor pipe, there being air 3 opening-s through the wall of said combustion chamber adjacent the rear extremity thereof.
2. A liquid: hydrocarbon fuel burner as described in claim 1 in which the openings in said pipe ring are directed inwardly and rearwardly on a conical angle to direct the fuel discharging therefrom. against the. cylindrical wall of said combustion: chamber.
3. A liquid hydrocarbon. fuel burner asdescribed: in claim 2 in. which the orifice in' said orifice member is inclined at an acute angle to the axis of said expansion. chamber so as to. di-
rect vapor against the inner wall of the latter..
