V I M WWWWWWWWW W A Y x 3 m w m WIhESEES ROBERT W. LAWTON, OF SAN FRANCISCO, CALIFORNIA.
HYDROGARBON-BURNER.
Specification of Letters Patent.
Application filed June 27, 1911.
Patented Mar. 19, 1912.
Serial No. 685,551.
To all whom it may concern Be it known that I, ROBERT W. LAWTON, a. citizen of theUnited States, residing at the city and county of San Francisco and State of California, have invented certain new and useful Improvements in Hydrocarbon-Burners, of which the following is a specification. i
The present invention relates to an improved burner for use in connection with furnaces generally for atomizing hydrocarbon oils, the object being the production of a simple andinexpensive burner of such construction that the oil and steam passing therethrough will be'discharged in a solid core-like stream into a suitable bonnet attached to the forward end thereof, through which the oil and steam is conveyed with a whirling action, air for proper combustion being drawn therein, and the whole forced from the bonnet in a cone-shaped divergent which nozzle serves as a sprayer for the oil.
and steam, as hereinafter explained. The said nozzle 3 is formed with a central opening or outlet 4, with which the open end of the oil pipe 1 communicates, and the nozzle 3 is further provided with a series of circumferentially lnwardly inclined passageways or openings 5, the terminal points of. which surround the central outlet 4 of the said nozzle. The conical nozzle is provided with a rearwardly extended interiorly screwthreaded circular wall 6, into which is screwed the forward end of a steam pipe 7 which pipe surrounds the oil pipe 1, and forms an annular passageway 8 for the flow of the steam toward the conical nozzle.
To the end of the nozzle3 is secured a bonnet or hood 9, the inner end face of which is shaped to conform to the inclined face of the said nozzle, and the bonnet or hood is held thereto by means of a coupling ring 10 which screws onto the exterior screwthreaded end 11 thereof, the said coupling r1ng bearing onto a circumferential shoulder 12 of-the nozzle 3. The bonnet or hood 9 is inwardly inclined for a part of its length from the rear end thereof, and thence outwardly inclined for the remainder of its length. The interior wall of the outwardly inclinedsection of the bonnet or hood is provided with a series of spirally arran ed ooves or ducts 13, which extend the 11 ength of the said outwardly inclined section 9 of the bonnet or hood 9, and in the inwardly inclined section thereof adjacent the nozzle 3 is formed a series of circumferentially disposed inclined air inlets or ports 14, through which fresh air is drawn into the bonnet or hood for intermixing with the flowing stream of oil and steam passing therethrough to secure perfect combustion.
In operation, the oil is ejected through the central outlet orifice 4 of the nozzle 3 into the bonnet or hood 9, the temperature thereof being raised'b the surrounding steam flowin through t e annular passageway 8 forme by .the pipe 7. The steam discharges into the bonnet or hood through the 1nwardly inclined passageways 5, surrounding and enveloping the stream of oil flowing through the outlet orifice 4 and holding the same as a core-like stream, the steam and oil thus flowing in a compact form through the bonnet or hood. The'vacuum caused b the bod of oil and steam flowing throug the sai bonnet or hood causes a suction of fresh air through the inclined openin 14, which intermixes with the steam and oil for insurin proper combustion.
As t e intermixed combustible stream passes through the outwardl inclined section 9' of the bonnet or hoo it is given a whirlin action by reason of the spirally dispose ducts 13, which causes a thorough intermixing of the steam, oil and air. The
intermixed stream as discharging from the outlet end of said section in a cone shaped outwardly diverging stream, is ignited, producing a flame which is cone shaped. By reason ofthe whirling action of the ignited vapor, a greater projection of the flame is obtained than would otherwise take place, with the result that the flame will cling to the furnace wall to better advantage, and for a longer period of time than heretofore, thereby causing the flame 10 give up to the fullest extent its units of eat.
Having thus described the invention what is claimed as new and desired to be protected by Letters Patent is 7 l. The combination with an oil pipe, of a conical nozzle provided with a central outlet orifice to which said pipe is secured, a steam pipe secured to said nozzle and surrounding the oil pipe, a circumferential series of inwardly inclined passageways in the nozzle for the discharge of the steam, a bonnet or hood provided in its inner end portion with a series of circumferentially disposed inclined air inlets, means for uniting'the bonnet or hood to the nozzle, the said bonnet or hood being inwardly inclined for a portion of its len th from its 1 inner end and outwardly inclined toward its discharge end, and provided in the interior wall of its outwardly inclined section with a series of spirally arranged grooves.
2. In a hydrocarbon burner the combination with a nozzle thereof, provided with a central discharge orifice, of an oil pipe secured to said nozzle, a steam pipe secured to the nozzle and surrounding the oil pi e, the said nozzle being provided with a p urality of outlets for the flow of steam therethrough, the bonnet or hood. attached to the said nozzle and provided at its inner end/portion with a series of air inlet ports, the said bonnet or hood being inwardly inclined for a portion of its length from the inner end thereof, and thence outwardly inclined to the discharge end, the interior wall of the outwardly inclined portion of r the said bonnet or hood being provided with a series of spirally arranged grooves.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
