HYDROCARBON-BURNER.

Specification of Letters Patent.

Application filed March 13, 1912.

Patented Dec. 2,1913.

Serial No. 683,406.

To all whom it may concern:

Be it known that I, EUGENE A. WHITTEN, a citizen of the United States, residing at Maricopa, in the county of Kern and State of California, (post-office address, Maricopa, California,) have invented new and useful Improvements in Hydrocarbon- Burners, of which the following is a specification.

This invention relates to improvements in hydrocarbon burners and particularly to that class of burners in which steam or air under pressure is employed for atomlzmg the oil.

It is an object of the invention to provide an oil burner in which the oil is delivered to the burner through one of the pipes thereof carrying air or steam under pressure.

It is also an object of the invention to provide a burner in which meeting streams of fluids under pressure are discharged from the burner, one of said streams carrying the oil in atomized form therewith.

It is a still further object of the invention to provide a burner in which a plurality of fluids under pressure are adapted to meet when discharged from a common outlet, oil being supplied with one of said fluids under pressure.

In the accompanying drawing forming a part of this specification, Figure 1 is a side elevation of the improved oil burner as in position in acombustion chamber, a portion of the burner being shown in section to reveal the outlet of the oil therein. Fig. 2 is an end elevation of the improved burner looking at the discharge outlet there of. Fig. 3 is a central longitudinal sectional view through the discharge portion of the burner, taken upon the line 83 of Fig. 2. Fig. 4 is a detail sectional view taken upon the line 4= 1 of Fig. 3. Fig. 5 is a detail perspective view of the partition member used in the nozzle of the mechanism.

The details and features of the invention will now be more particularly described,-

and steam supply pipes 5 and 6 are ar ranged in any suitable relation to the combustion chamber of a furnace or heater as 7 and a branch pipe extends from the oil supply pipe into the said combustion chamber. A valve 9 is provided in the oil pipe for controlling the flow of oil and a T- coupling 10 connects the said valve with the pipe 8. A branch steam pipe 11 is also provided, controlled by a valve 12. A pipe 13 connected with the branch pipe 11 passes through the T coupling 10 and extends into the pipe 8 for almost the entire length thereof, the inner end of said pipe 13 being open. A suitable fitting 1 1 is supplied for connecting the pipe 13 with the T coupling 10 where it enters the same so as to prevent the escape of steam or oil at that point. The pipe 13 forms one of the supplies for steam to the .burner. A second supply is also afforded by a pipe 15 which is connected with the supply pipe 6 and extends into the combustion chamber as clearly shown in Fig. 1. A valve 16 controls the passage of steam to and through the pipe 15. The open. end of the steam pipe 13 is preferably provided with supporting pins or standards 17 adapted to hold the piping out of axial position and preferably above the axis of the pipe 8 as clearly shown in Figs. 1 and 3.

Between the ends of the pipes 8 and 15 is arranged the nozzle portion of the burner. The end of the pipe 8 is provided with an elbow 18, while the pipe 15 is provided with .an elbow 19. Nozzle members 20 and 21 are connected with said elbows as shown in Fig. 3, a reducing coupling 22 being usually interposed between the elbow 19 and the nozzle member 21. The opposing ends of the nozzle members 20 and 21 are provided with flanges, one of said flanges carrying a coupling 23 in engagement therewith, while the other flange is exteriorly threaded as at 24 to engage said coupling when the parts are to be drawn together. An intermediate nozzle member 25 is also provided in the form of a partial disk having studs 26 adapted to project into recesses 27 formed in the nozzle section 21 to prevent the turning of said intermediate nozzle member. The intermediate nozzle member is made of a proper thickness to leave a suitable discharge opening between the fiange of the nozzle member 21 and the threaded flange 24 upon one side of the burner, the coupling 28 being cut away at 28 for affording such an opening. The intermediate member 25 is formed with a segmental recess portion approximately quadrantal in form and a thinned portion 30 is provided therein, adapted to project into the discharge opening as will be clearly understood by reference to Fig. 3. The thinned portion of the member is thus in position to convey the discharges from the two burner pipes as they escape throughthe said opening 28.

The oil is introduced to the burner through the pipe 8. The steam or other fluid medium under pressure escapes from the pipe 13 and takes up the oil and atomizes it in the elbow 18 so that the oil and steam are well mixed before reaching the outlet openings. A more thorough mixing and atomizing of the oil is produced however when the steam from the pipe 15, meets the oil and steam at the edge of the thinned portion 30 of the intermediate nozzle member. The pressure of the steam is never allowed to reach such a degree as to prevent the oil from entering and passing through the pipe 8, since pressure of this height is not required in atomizing the oil.

The mechanism is such that two streams of steam, air or other fluid under pressure may be driven from the discharge opening of a burner, practically impinging upon each other, one of said streams carrying oil in an atomized condition so that the oil is thoroughly atomized and properly vaporized as it takes flame at the outlet of the burner. The extension of the steam pipe 13 in the oil pipe 8 properly warms the oil as itapproaches the burner.

What I claim is:

1. A hydrocarbon burner, comprising an oil supply pipe having a terminal discharge opening and a pair of supply pipes to carry a fluid under pressure, each of said pipes having discharge openings, one of said supply pipes being inclosed within said oil sup-- ply pipe and having its discharge opening intermediate the discharge opening of said oil supply pipe and the oppositelydisposed end of said oil pipe, the second of said supply pipes having its discharge opening adacent to said oil supply pipe discharge opening and a deflector interposed between said oil pipe discharge opening and said second supply pipe discharge opening.

2. A burner havin an oil supply pipe and a plurality of pipes adapted to carry fluid under pressure, one of the latter pipes extending into the piping of the oil supply and discharging therein, nozzle members connected with the supply pipes, a coupling for connecting said members having a discharge opening in its walls, and a spreading member mounted intermediate said nozzle members in said coupling and extending into said discharge opening.

3. A hydrocarbon burner having an oil supply pipe and steam supply pipes, one of the steam supply pipes being smaller than the oil supply pipe and extending into the same so as to dischargetherein, spacing means for holding the open end of the steam supply pipe in a proper position within the oil supply pipe, a nozzle member mounted between the oil supply pipe and the other of the steam supply pipes, elbows connecting the oil and second mentioned of the steam supply pipes with said nozzle member, the nozzle member having a discharge opening in one of its walls, and a member mounted Within the nozzle having a thinned spreading portion extending into the discharge opening.

In witness that I claim the foregoing I have hereunto subscribed my name this 4th day of March, 1912.
