UNITED STATES ROBERT C. XVADE, OF BROWNSVILLE, TEXAS.
OIL BURNER.
Appcaton filed March 28, 1923. Serial No. 628,233.
To mi! renom 'it 97mg/ concern Be It known that I. ROBERT C. VADE, a citizen of the United States, residing at Brownsville in the count f of Cameron and State of Texas, have. invented certain new and useful Improvements in Oil Burners, of which the following is a specification.
This invention relates to oil burners and .is designed to use an oily fuel, which is not under pressure, and air, or steam, which is under pressure, and direct it into the air stream for feeding the oil to the burner by pressure exerted on the air stream, to direct the combined streams of air or steam and fuel through the nozzle of the burner.
ln accordance with the invention, there is l'novided a nozzle enteringl a body or sleeve which is made of massive construction except where particular' n'iassiveness is not desii-ed, and into the nozzle there is directed an air or steam feed with the air or steam under pressure and so arranged as to issue through the nozzle in an axial stream.
The sleeve is somewhat larger in diameter than the air stream, and the fuel is directed to the sleeve through one side of the latter and into the air stream to be drawn thereby and injected through the sleeve, which latter in the larger sizes of nozzles provides means for the mixing of the air and fuel before being ejected and consumed.
In combined air or steamand fuel nozzles as heretofore constructed, it is customary to utilize the streamssinmltaDeOusly, both streams beingl under pressure and the mixing taking place at the exit end.
Vln accordance with the present invention, the air or steam stream is the onlystream under pressure, and this airstre-am is arranged centrally with respect to the fuel stream and issues through a nozzle into one side of which the fuel stream is directed.
ln accordance with the invention, there is' provided an air pipe centrally of a nozzle through which the air is directed, and this air nozzle is surrounded by a heavier walled tube extendingl beyond the exit end of the `air nozzle, while the fuel is fed to one side of the air nozzle so that the streams of fuel and air lTom and are together e3ected through the air nozzle to pass out together through 4 another larger nozzle where the mixture of the two streams takes place.
These two streams unite and mix before issuance from the mouth of the. burner, and the supply of air close to the fuel is such as to thoroughly sustain combustion, while at the same time the stream of fuel is drawn into and burns as it escapes from the air nozzle without any back pressure in the fuel nozzle.
For this reason, the feed of fuel through -i the burner is due entirely to the pressure created by the issuance of theair drawing on the lsupply of fuel. i
The invention will be best understood from a consideration of the following detailed description taken in connection with the accompanying drawings forming part of this specification, with the understanding` that the invention is not confined to any strict conformity with the showing of the drawings, but may be changed and modified so long as such changes and modifications mark no material departure from the salient features of the invention as expressed in the appended claim.
Figure l is a longitudinal central section, partly in section, of the improved device.
Fig. 2 is a section on the line 2--2 of Fig. l.
Fig. 3 is a longitudinal section partly in section, of a smaller type of burner incorporating the principles of the burner illustrated in Figs. l and 2.
Referring to the drawings, there is shown a cylindrical main stock or body l having` an enlarged longitudinal bore 9. at the rear end which leads into an axial smaller bore 3 opening atthe forward end.
The bore 2 is interiorly threaded as at l and into this bore is threaded a reduced extension 6 constituting an inner nozzle, extending from a minor body portion 5 which is, as shown, of the same diameter as the body l. The body 5 is provided with an axial bore 8 which extends into the nozzle or extension 6 and the extension has an axial bore 8"L `formed theretlnfongh of materially less diameter than the bore 8 and in alignment therewith.
The bores 2 and 3 are joined by a tapered portion 3 and the nozzle 6 terminates at the end of the enlarged bore 2 where the tapered portion begins.
Threaded into the body 1- from one side` is a pipe 13 having the forward end 14 screw threaded to enter through the side thereof which pipe 13 leadsI from the fuel supply, not shown.
The pipe end 14 opens into a chamber l5 surrounding the conical end G of the nozzle 5.
By the construction shown and described, air fed throrigh the pipe 12 into the nozzle end tl, under pressure, but the pipe 13 does not contain any liquid or fluid under pressure. the tlow of the liquid or fuel through the pipe 13 being caused by the suction created in the. chan'iber 15 by the passage of the air under pressure from the pipe 12 through the nozzle end (i to the bore 3 and into the sleeve l.
1n the struct-ure shown in Fig. 3, the nozzle end (S is replaced by a longer nozzle G1L and the body 3 is replaced by a tapered body 3.
The tapered body 23: is of considerable lengte and at the outer end has a reduc-ed bore giving a less sturdy construction than the body i3 shown in Fig. 1.
rPhe result is that the body 3 will, break down under excessive heat when used as a nozzle and consequently can not be employed on structures where the heat is excessive, so that on structures as shown in Fig. 3, their adaptation is limited to the more fr gile forms of heaters, the more sturdy forni being contined to the structures illustrated in Figs. 1 and 2. li/ioreover the nipple (3 is provided with a wre `ch-receiving enlargement l0, and the pipe Yl2 is provided with a cut-ott valve 17 by means of which a stream of air under pressure may be directed through the nipple 6 to cause. the feed of fuel through the pipe 1&3.
ln Fig. 3 the two pipes 1Q and 13 are joined together by bridge pieces 16 to serre as a handle for facilitating the handling of the burner shown in Fig. 3.
The structure of Eig. 3 constituting the small type of nozzle is essential and convenient and is designed for the purpose of cleaning auton'iobilcs and for other like uses about gz-irages, for the engines and similar classes of inacl-iiuery often become covered with grease and oil.
.ln most garages, there are airtanks with pipes running to Various parts of the shop which can be connected to the part 12 by a hose.
The pipe 13 may represent a short hose to be dropped int-o a bucket of gasoline and the whole be moved from place to place, after which the valve 17 is opened so that the air from the air tank is drawn in and atomizes and sprays the gasoline from the nozzle to produce an efcient cleaning stream of gasoline.
By reducing the bore of the nozzle tip 3, this might be used as a burning tip for burning ol` the spines from cactus for feeding cattle.l
lith respect to the burner shown in Fig. 1, the device may be employed with heavy fuel, with any suitable character of burner, in power plants, locomotives, etc.
In using the nozzle structure as an oil burner under a steam boiler, instead of air.
under pressure in the pipe 12, steam from the burner is used.
An auxiliary air tank may be used in connection with this device so that in starting a lire under a cold boiler, air under pressure may be fed into pipe 12 until there is sufiicient steam in the boiler to operate said burner.
Vilhat is claimed is A burner of the character described, coinprising a main body portion having a pair of aligned axial bores torn'ied therethrough, one of greater diameter than the other, a tapered portion between the said bores` the bore of greatest diameter being interior-ly threaded, a minor body portion comprisingl a body of a diameter equal to the diameter of said main portion and having a relatively large bore theretln'ough and further having a reduced extension constituting an inner nozzle and adapted to thread into said tlireaded bore, said inner nozzle terminating at the end of the enlarged bore, said bore in said minor portion extending .into said nozzle and said nozzle having an aXi al bore therethrough of materially less diameter than that bore in the minor portion, an air inlet nipple threaded at one end into the bore of the minor portion, an air pipe connected thereto, and a fuel. inlet tube opening into the bore of greater dianieter in them-ain body portion at a point slightly in the rear of the outlet of said nozzle and directed at an inclinati-on toward the discharge end of the burner.
Iny testnnony whereof, I aliix my signature hereto.
ROBERT C'. VADE.
