c. PpvALLELY, lBURNER FOR GAS AND OIL.

APPLICATION FILED IUNE 3 l 1919.

CORNELIUS r. VALLELY, or

BURNER FOR 1,381,144. Specification of Application led .Tune 3,

To all whom it may concern Be it known that I, CORNELIUS P. Vnif LELY, a citizen of the United States, residingV at 120 W. Washington St., Bradford, in the county of McKeanl and State of 4-Penna., have invented certain new and useful Improvements in Burners forA Gas andl Oila of which the following is a specification.

This invention relates to improvements in hydrocarbon burners, and has for its object to provide a simple but eicient burner designed for use in connection with natural gas, crude petroleum and other fuel oils used in a variety of apparatuses for heating or smelting purposes.

The primary object of this invention is to provide means whereby the fuel oil is atomized with steam or other fluid under pressure and there commingled with air or natural gas, or in combination with natural gas and air, in varyingl proportions to suit the re uirements for perfectcombustion.

ther objects of the invention will be apparent from the following description and claims.

In the accompanying drawings I have illustrated the preferred embodiment of my invention, and the improved details of construction, and arrangement of parts thereof will be apparent from the specific description hereinafter contained when read in connection with such drawings.

In the drawings: f

Figure 1, is a longitudinal sectional view of the burner.

Fig. 2, is a cross sectional View of the burner on the lines 2-2, Fig. 1.

Fig. 3, is an end view.- l

Referring to the drawings, wherein like reference numerals designate corresponding parts in the several views, v1- represents the outer casing of relatively large size, terminating at the one end in the integral reduced nozzle portion 2, and at the other end in the internally threaded aperture 3, into which is screw threaded the interiorly disposed ejecting nozzle 4.

The nozzle 4, has formed at its enlarged end portion, a flange 5 into which lead the duct inlets 6 and 7. These ducts join in the form of a Y, into the one opening 8, at the mouth of the ej ecting nozzle 4.

GAS AND OIL.

1919. Serial No. 301,469.

Within the enlarged portion of the outer casing 1, is a cylindrical shaped cavity 9 into which extends the projecting boss mem-7 ber 10, formed integral with and providing an annular space 11, between the said projecting boss member 10, and the outer's'hellof the casing 1. v

Beginning .at the outer end of the nozzle 2, and extending to the end of the projecting boss member 10, is a passage 12 of gradually tapering enlargement, communicating with the cavity 9, within the outer casing 1, communicating with the annular space 11, are. ingress ports 13 and 14, the purpose of which will be hereinafter explained.

Referring that the projecting apertured boss member 1Q, lis circumferentially disposed around the ejector nozzle .4, and that the discharge end of the ejector nozzle 4, is disposed well forward of the axial line of the duct 13, and that the duct'14 is disposed forward of the mouth of the aperture in the projecting member l0. The'relative position of the ducts 13 and 14, in connection with the projecting member 10, and the ej ecting nozzle 4, onstitute important features of this invenion.

Connected with the duct 6, of the ejector nozzle 4, is the pipe 61, by which fuel oil is drawn from any suitable source of supply (not shown) and is commingled with a suitable fluid under pressure, fed through the duct 7 by the supply pipe 71, this fluid may be steam, compressed air, or natural gas under pressure. I prefer to use steam, as the temperatureof steam aids in thevaporizing of the fuel oils.

It is well known in the art that to convert any liquid into a vapor, that a cooling effect is created within the immediate zone of operation, tending to cause condensation which is wasteful and detrimental to high efficiency. I overcome this objection by the novel arrangement of the commingling of the various fluids before they are projected from the burner for combustion.

In the operation of the device as described, the oil valve (not shown) is adjusted to feed the desired proportion of oil. Steam or compressed air is then supplied to the duct 7, and is discharged through the to Fig. 1, it will be observed the casing l,

opening 8, under the influence of which a partial vacuum will be caused in the duct 6, causing a siphoning ofthe oil through the oil supply pipe 61 to the point at the intersection of the branches of the Y, where it commingles with the steam and is atomized thereby. f

As the mixture of atomized oiland steam passes out of the ejector nozzle 4, it is projected into the aperture 12, causing `a suction thereby which creates a partial vacuum in the cavity 9, under theinfluence of which air will be drawn through theduct 14towaerate forcombustion purposes, and gas will be drawn through the-duct 13, It is to be understood that the gas isnot essen tial at all times to secure perfect combustion, but its use is to be determined byV the particular effect desired, it being understood that the gas may be used in combustion with i the oil, or substituted therefor.

The amount of the air, and the proportion of gas to be supplied will be regulated by the use of valves, (not shown) in manner well known inthe art.

As the combustiblemixture is dischargedfrom the end of nozzle 2, it is projected into the fire box or furnace and therein ignited. The nozzle 2 being in close proximity tor the zone of combustion, will become heated and will radiate heat into the annular space 11, into whichY is fed atmospheric air through the duct 14, causing a superheating of the air before it is commingled with the gas coming into the cavity 9, through the duct 13. This preheating of the air eliminates condensation and aids in 'vaporizing the atomized oil before it is discharged into the fire box orifurnace.

From thefforegoing description it will be Y.

seen that the steam or compressed air passing through the duct 7, isthe only fluid under pressure, and by the novel arrangement of my device, the oil, air and gas supply are each drawn into the burner by the vacuum effect created by the suction of the steam discharge, whereby an automaticfeed of these combustible uids is provided, self regulated in proportion to .the volume and force of discharge of the steam or other fluid under pressure.

While I have herein disclosed a particular embodiment of the invention, it will be apparent to persons skilled in the art that changes and alterations may be made withcharge end disposed within theaperture-in f said boss, forming an annulary space around said nozzle; ingress ports foradinission ofM air and gas in communication with said annular space and adapted tofbe drawn there.-
