OIL BURNER.

Application filed February 21, 1920. Serial No. 360,277.

To all whom it may concern:

Be it known that I, THEODORE BOUDREAUX, a citizen of the United States, residing at Marshall, in the county of Harrison and State of Texas, have invented new and useful Improvements in Oil Burners, of which toe following is a specification.

This invention relates to oil burners wherein the oil is superheated, and vaporized as it passes through the burner proper, and is ejected in the form of a spray from one end of the burner under the influence of steam, the invention residing in the construction, combination and arrangement of parts as claimed.

The drawings forming part of this specification the like numerals of reference indicate the corresponding parts in the several views and wherein:

Figure 1 is a front end elevation of the burner constructed in accordance with my invention.

Figure 2 is a rear end elevation.

Figure 8 is a longitudinal sectional view taken on line 33 of Figure 2.

Figure 4 is a fragmentary longitudinal section taken on line 4l4 of Figure 2.

Figure 5 is a transverse sectional view taken on line 5--5 of Figure 3.

Referring to the drawings in detail, indicates the body of the burner which is of tubular formation in cross section and which may vary in size without departing from the spirit of the invention. The front end is indicated at 11 and is provided with a series of transverse openings 12 through which the fuel is sprayed into the furnace or fire-box in the manner to be hereinafter described. The opposite end of the body member is closed by means of a cap 13 which is preferably screwed upon the body at 10 as shown. A continuous super-heater coil 14 is disposed within the body 10 and has its ends 15 and 16 respectively arranged in parallelism, and projected through openings in the cap 13. Each of the extremities is threaded and has associated therewith a lock nut 17. An elbow 18 is associated with the extremity 15 of the coil, the elbow being equipped with a nipple 19 for connection with a suitable source of steam supply. A cap 20 is associated with the extremity 16 of the coil which constitutes the drain end,

the cap 20 being provided with a drain opening 21 through which the water of corn densation escapes.

A T-coupling as indicated at 22 is connected with the cap 13 through the instrumentality of a nipple 23. This nipple is equipped with a lock nut indicated at 24. The stem 25 of this coupling is threaded and adapted to be connected with a suitable source of fuel supply, while associated with the remaining extremity of the coupling, is a steam nozzle 26. This nozzle projects an appreciable distance within the coupling, being threaded as at 27 and equipped with a lock nut 28.

In practice, oil is conveyed from a suitable source through the inlet 25 of the coupling 22, thence through'the nipple 28 into the body end of the burner. The oil is forced through the body, then under the influence of the steam pressure admitted to the body 10 through the nozzle 26, the latter being coupled with a suitable source of steam supply for this purpose. Steam is also admitted through the nipple 19 into the extremity 15 of the superheater, the steam circulating through the said heater or coil 14, thus superheating and vaporizing the oil as will be readily understood. The fuel thus vap0rized is forced through the openings 12 at one end of the burner in the form of a spray into the fire box. As hereinabove pointed out, the extremity 16 of the coil or superheater constitutes the drain end and the water of condensation allowed to escape through this extremity of the drain opening 21 in the cap which is associated with the extremity. The invention provides for a simple construction and a compact arrange ment of parts, also for the saving of a large percentage of fuel.

While it is believed that from the foregoing description the nature and EClVflJL tages of the invention will be readily apparent, I desire to have it understood. that I do not limit myself in this connection and that such changes may be resorted to when desired as fall within the scope of one is claimed.

Having described the invention what I claim is An oil burner comprising a tubular body portion having an open end exteriorly terior of the body, said couplingpresenting both a steam inlet and an oil inlet, and a cap having an outlet opening; associated with one of the terminal ends of the said coil and a connection for a steam supply associated with the other terminal end of the coil, said cap and connection being interchangeable on the said terminal ends.

In testimony whereof I afliX my signature.

THEO. BOUDREAUX.
