G. C' WAY OIL BURNER Oct. 6, 1936.

Patented Oct. 6, 1936 UNITED STATES PATENT OFFICE twelfth to James Utterbach,

Ohio, and one-twelfth to William H. Does, London, Ky.

Application April 2, 1935, Serial No. 14,307

1 Claim.

This invention I am about to describe has for an object to produce a burner of the type employing a liquid fuel of the character of crude oil such as petroleum and the like, in which certain volatile elements are present, capable of distillation therefrom upon the application of heat thereto, with a resultant residue of the nature of a highly carbonized by-product of non-volatile 'quality.

A further object is to produce a burner for crude oil and similar fuel in which marked simplicity of construction and operation is obtained as compared with other burners known to me.

These and other objects are attained in the burner described in the following specification and illustrated in the accompanying drawing, in which:

Fig. 1 is a plan view of the burner embodying my invention. 7

Fig. 2 is a sectional view taken on the line 2--2 of Fig. 1.

Fig. 3 is a sectional view taken on the line 33 of Fig. 2.

Fig. 4 is a fragmental sectional view taken on the line 44 of Fig. 1.

The burner I have shown consists of a pan H which is provided with a rim l2, a central opening I 3 which is flanged as shown at I4, an oil entrance opening IS, a gas exit opening I 6, residue discharge openings I! and. I8, openings l9 and 20 which communicate through passage 2|, a priming opening 22, a heating dome 23 which covers openings l5, l1 and IS, a heating dome 24 which covers openings l6, l8 and 20, a burner 25 which is mounted in flange M of opening [3, and a gas jet 26 which connects with gas exit l6 and discharges into opening I3.

Domes

23 and 24 covering openings l5, l1, l9, l6, I8 and 20, are sealed to the pan H at their lower edges by bolts 21. The pan, because of its rim l2 and opening flange l4, may receive and retain a wicking 20 preferably of incombustible characteristics, such as asbestos, by means of which oil entering the pan through opening 22 will fill the pan and become absorbed by the wicking so as to permit of its being lighted for initial heating of the burner domes, whereby gas generation will start.

The openings l5, l6, I9, and 20 are provided with short pipe lengths which extend upwardly into the

domes

23 and 24, the respective pipes l 5' and 20' of the openings l5 and 20 being shorter than the respective pipes l6 and IS in openings l6 and I9, whereby inlet of oil through opening l5 will permit of a normal oil level of the height of the shorter pipe I5 being maintained, somewhat as shown at oil level 29 in Fig. 2, the higher pipe IS in opening l9 carrying ofi? the vapor and unvaporized oil into passage 2|, thence upwardly through the shorter tube 28 in opening 20, such unvaporized oil also passing over with the vapor and possibly gradually accumulating until a normal level may be as shown at 30 is attained, the gas therefrom passing off through the higher pipe l6 of opening l6, thence through the jet 26 and upwardly for discharge from the orifices of burner 25, at which point the gas may be ignited and the resultant flame caused to impinge the walls at the tops of the domes.

Obviously, the heated domes create gasification of the oil within them, initial gasification taking place in dome 23 and final gasification taking place in dome 24.

The residue in the oil within the domes gradually becomes such that no volatile part remains and the mass of the residue has become highly impregnated with carbon. It is essential that provision be made for removal of this carbonized, nonvolatile residue. For this purpose the openings I1 and I8, with their attached pipes are provided. A small feature which I have added, so that the valve control on the pipes openings I1 and I8 may not be the only means for preventing oil. escaping and also so that automatic closure when all residue has been drained from the domes, may be effected, is the ball valve 3| of opening I! and ball valve 32 of opening I8.

Having thus described my invention what I claim is:

An oil burner comprising a priming pan, a heating dome covering and sealing off a portion of said pan at each end thereof, a burner located on the pan between the domes and designed to direct its flames against the domes, each of said sealed ofi portions having an inlet and an outlet, the outlet of one dome connecting with the inlet of the other dome, the inlet of said one dome connecting with a source of oil supply, the outlet of the other dome connecting with the burner, said inlets extending within the domes to lower elevations than do the outlets therein, said pan outside the domes having an oil inlet for preliminary heating purposes, said dome-sealed portions of the pan having drainage openings therein, and means to close or open said openings as required.
