The invention relates to liquid fuel burners of the type in Whichthe liquid fuel is atomized by air or other fluid pressure.
The objects of the invention are to provide a burner of this character inV which the liquid fuel is ejected in a thin film at nearly right angles to the blast of air or other fluid and against a toothed rin'g fwhich serves to further break up the-fuel.
The above and other objects may be attained by constructing the burner in the manner` illustrated in the accompanying drawing, in Which Figure 1 is a longitudinal, sectional vieW i through a burn-er embodying the invention;
F ig. 2, an end' elevation of the oil tube and ring With the valve removed. Y
Similar numerals refer to similar `parts throughout the drawing.
The burner comprises the L-shaped casing 1, having the upper neck 2 to Which an air blast pipe 3 is connected, and the reduced neck 4 at one end to receive the oil tube 5.
The oil tube is held in adjusted position Within the burner casing as by a `set screw 6 and extends longitudinally through the casingA to a point near the outlet end 7, to which may be connected any suitable tubular member 8 in which the combustion takes place. f
The outer end of the oil pipe may be threaded as at 9 for the connection of a coupling 10, to which the oil supply pipe 11 is attached. As illustrated in the drawing, this coupling may be in the form of a T, and a threaded plug 12 may be provided for closing the outer end.
rl`he inner end of the oil tube 5 terminates in the conical portion 13 having the reduced valve seat 1st at its extremity. Theconical valve 15 is mounted upon the stem 16 axially slidably located through Webs 17. f
A coil spring 18 is located around the stem between one of the Webs 17 and the shoulder 19 fixed upon the outer end portion of the stem, for the purpose of normally holding l I lng provided With an outlet opening, an air the valve 15 seated upon the seat 14 at the tapered end of the oil tube.
Ai ring 20, triangular in cross section, is located concentrically With the taperedy end of the oil tube 5, being preferably formed in`` tegral therewith and connected as by the 1924. serial No. 704,170.
Webs 21. This ring 1s provided With the radial slots 22 located through the reduced or tapered side thereof.
In the operation of the burner, oil is sup plied through the pipe l1 into the tube 5r 'and air under` pressure is supplied through thin ydisk shaped film .directedtoward the slotted ring 20.
rilhe -air passing around the insideV ofthe ring toward the tube 8, breaks up the greater part of this `film of oil, mixing the atomized oil With the air and carrying the same into the combustion tube 8.
` rIhe remainderof the oilstriking the slot` ted ringQO, Willv be further broken up and any particles thereof which `pass through the slots in the ring, will be caught in a concent-ric current of'air passing varound the outsideof the ring and will be properly mixed With the air as it passes into the combustion tube 8.
I claim i 1. A liquid fuel burner comprising a casing, an air conducting pipe communicating With the casing, an oil conducting tube exe tending into the casing, a spring pressed valve normally closing the inner end of the oil tube and a slotted ring spaced from the valve andthe interior of the casing and c oaxial therewith the valve being arranged to deflect and break up the oil lagainst said ring.
ing, an air conducting pipe communicating with the casing, an oil conducting tube ex oil tube, a slotted ring spaced from the valve and the interior of the casing and coaxial therewith, and means for adjusting the tube longitudinally Withinthe casing the valve being arranged to deflect and break up the oil against said ring.
3. A liquid fuel burner comprising a casconducting pipe communicating With the casing, an oil tube extending into the casing,`a spring pressed valve fornormally clos# ing the inner end of the oil tube, a ring spaced freie the valve .and xed t0 the eil 2. A liquid fuel burner comprising av casthe inner end of the oil tube, a slotted ring 10 spaced from the valve and fixed to the oil tube, and means for adjusting the oil tube and ring with reference to the Outlet opening the valve being arranged to deflect and break up oil against said ring.
In testimony that I claim the above, I have hereunto subscribed my name.
