GEORGE J OINER, OF NEW YORK, N. Y.

LIQUID-FUEL BURNER.

Application filed September 8, 1917. Serial No. 190,386.

To all whom/it may concern:

Be it knownthat I, Gnonon JoINER, citiresidvented certain new and useful Improvements in Liquid-Fuel Burners,'of which the following is a specification.

The present invention relates to a liquid fuel burner, and itsobject is to provide a simply constructed device by means of which an intensely hot flame may be produced.

In carrying my invention into practice, I provide suitable-means'for producing a jet or spray of a mixture of such substances as steam and oil, whereby to create a suction action to draw desired quantities of air into the space or chamber where combustion occurs.

The invention is susceptible of embodiment in a great variety of mechanical forms, and'for the purpose of illustrating the practical application of the principle involved, I have shown one form of the invention in the accompanying drawing wherein Figure 1 is a vertical sectional view of a burner adapted to carry out the principle of the invention Fig. 2 is a vertical cross sectional view on the line 22 of Fig. 1 looking in the direction of the arrows; and

Fig. 3 is a vertical sectional view of one of the injectors or sprayers.

It will be understood that the burner may be placed in the fire box of a furnace or. in the combustion chamber under a boiler, or in any desired place wherein firing is to be effected.

Referring to the drawing, but more particularly to Fig. 1 thereof, 10 denotes a cylinder which is open at both ends, the inner end 10 opening into the combustion chamber and the outer end 10 opening to atmosphere. Arranged within this cylinder, I provide one or more injector units or sprayers, the construction of which is shown in detail in Fig. 3.

The outlet ends of the sprayer units or nozzles are spaced inwardly from the edge or rim 10 of the cylinder 10 a suflicient distance so that when the mixture issues from the outlet end of the nozzles at a proper velocity, a vacuum will be created within the cylinder 10, thus drawing quantities of atmospheric air into I Specification of Letters Patent.

'- or box 14,

Patented Jan. 14,1919.

Spaced from the cylinder 10, and co-axial therewith, is a second cylinder 11, which has an open end 12 alined with'the open end 10 of the cylinder, the opposite end of the cylinder 11 being provided with-a head 12 whereby this end of the cylinder is closed. The cylinder's lO and 11 are secured together and held in proper spaced relation by a series of stay bars 13, riveted at 14 to the cylinders 10 and 11 respectively. s

Referring now to Fig. 3 of the drawing, a description of the sprayer units willbe given. Each sprayer unit comprises a chest one end of which is formed as a constricted outlet nozzle 15 provided, with an outlet bore 16. Extending into the chest 14 and preferably co-axial, therewith is a pipe 17, the passage through which may be controlled by a valve or cock l8. Thispipe 17 communicates with any gas or fluid under pressure, and in practice I have found it desirable to connect the pipe 17 with a source of steam under pressure; The end of the pipe 17 within the box 14L is formed as a constricted nozzle 19 alined and concentric with the nozzle 15 of the box 1 1 Opening into the box 14 is a second pipe 20, the passage through which is also controllable by means of a valve or cock 21. The pipe 20 'at its end opposite that opening into the box 14 is connected with any suitable source of fuel, such as heavy or light oil, or any other fatty substance capable of being burned. In practice, the pipe 20 is connected with a supply of gasolene or other liquid oil. V

In Fig. 1, the pipes 17 and 20 are shown as being angular, and as being passed through perforations in the wall of cylinder 10, while in Fig. 3 the pipes 17 and 20 are shown as being substantially straight (except for a bend in pipe 20) and in the form of Fig. 3 these pipes 17 and 20 would extend in a direction parallel to the cylinder 10 throughout their extent.

I may use one, two or more sprayer units, dependent upon the character of the installation in which the burneris to be used. For. example, a single sprayer unit will be sufficient as a burner under a boiler of say 30 H. P., while for a H. P. boiler it would be desirable to have two or possibly three such sprayer units because of the greater amount of heat needed.

In operation a device such as that illustrated and described would operate to carry out the principle of my invention as follows :-T he cocks 18 and 21 would be opened whereby a commingled jet of steam and oil would issue through the bore 16 of nozzle 15. At this point, I desire to make it clear that but an infinitesimal quantity of oil is admitted; there being barely sufiicient oil needed for the operation of the burner. The air rushing through the cylinder 10 passes into the cylinder '11, strikes the head 12 thereof, rebounds, and then issues through the opening X between the cylinders 10 and 11. This mixture of fuel and air is ignited by any suitable means. I may ignite the same by placing a quantity of burning oilsoaked waste at the inner end of the cylinder 10, or I may insert a lighted plumbers torch or any other flame 1nto the opening X.

When ignition has thus been effected, it will continue just as long as the vacuum in said cylinder is maintained by the continuance of steam flowing through the pipe 17 and issuing at the nozzle 15. I may, of course,

regulate the quantity of steam passing through the pipe 17 by means of the valve 18, and I steam by any suitable means at the steam source.

- comprising may regulate the pressure of the What Iclaim'as new and desire to secure by Letters Patent is 1. A burner of the character described,

comprising a straight chamber open at both 7 2. A burner of the character described,

ders spaced and the other thereof being open at one end only, and a sprayer nozzle'in the first mentioned cylinder and adapted to induce the fiow' of an air current tioned cylinder. and out through the space between the said cylinders.

In testimony whereof I have affixed my signature in presence of two witnesses.
