WILLIAM H. WAFER, OF CHICAGO, ILLINOIS, ASSIGNOR OF ONE-HALF TO L. E. BELCIA, OF BEAUMONT, TEXAS.
OIL-BURNER.
SPECIFICATION forming part of Letters Patent No. 731,397, datedJ'une 16, 1903. Application filed December 10, 1902{ Serial No. 134,611. (No modelA To all whom it may concern.- Be it known that I, WILLIAM H. WAFER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Oil-Burners,of which the following is a specification.
This invention relates to improvements in that class of burners used for burning hydrocarbon oils or liquid fuel, and while it is more especially intended to be used for heating steam generators or boilers yet it is applicable for assaying furnaces, retorts, and for other heating purposes; and it consists in I 5 certain peculiarities of the construction,novel arrangement, and operation of the various parts thereof, as will be hereinafter more fully set forth and specifically claimed.
- The principal object'of the invention is to provide a burner foroil which shall be simple and inexpensive in construction and its parts so made and arranged that the best results may be obtained both by affording means for producing perfect combustion of the oil, as
wellas burning it in a uniform manner.
Another object is to furnish means for heating the oil or liquid fuel before its discharge for combustion and for atomizing it by means of steam and air.
0 Other objects and advantages of the invention will be disclosed in the subjoined description and explanation.
In order to enable others skilled in the art to which my invention pertains to make and 3 5 use the same, I will now proceed to describe it, referring to the accompanying drawings, in which-- a I Figure 1 is a viewin side elevation of an oil-burner embodying my invention. Fig. 2
is a View, partly in section and partly in elevation, the sectional part being taken on line -2 2 of Fig. 3 looking in the direction indicated by the arrows. Fig. 3 is a plan view of the 7 burner. Fig. lis a horizontal sectional view taken on line 4 4 of Fig. 1. Fig. 5 is a detached View of the oil-regulating valve, showing its inner surface or face; and Fig. 6 is a similar View of the steam-regulating valve employed at the discharging end of the burner.
Like numerals of reference refer to corresponding parts throughout the different views of the drawings.
The referencenumeral 10 represents the body or main portion of the burner and is usually made globular or substantially spherical in form. Located within the casing or body 10 and extending across its cavity is an oil-retaining tube 11, the ends of which are secured in openings in the bosses 12 and 13, which are located on opposite sides of the body or casing. The ends of the tube 11 are preferably secured in their respective openings by being expanded therein, the said openings being slightly flared, as shown. 6 Each of the bosses 12 and 13 is provided with external screw-threads to engage couplingnuts 14 and 15, which are employed to retain in position the nipples 16 and 17, the inner portions of which are slightly beveled to fit in the ends of the oil-tube. Connected at one of itsends to the nipples 16 and communieating with the tube llis an oil-supply pipe 18, the other end of which is connected to asupply of oil, (not shown,) which may be under pressure or fed by gravity. Connected at one of its ends to the nipple 17 and communicating with the tube 11 is a connectingpipe 19, which communicates atits other end with a portion 20 of the valve-casing, which may be provided with a boss 21, closed by means of a screw-plug 22, to which boss may be connected an auxiliary steam-pipe. (Not shown.) Communicating at one of its ends with the cavity of the body or casing 10 is a steam-supply pipe 23, which is connected at its other end to a source of steam-supply. (Not shown.) On the opposite side of the body from the pipe 23 is an externally-screwthreaded neck 24:, to which is secured, by means of a nut 25,-a nipple 26, which is connected, by means of an inner tube 27, to a pipe 28, the other end of which communicates with the portion 20 of the valve-casing. Secured at one of its ends to the inner portion 5 of the part 20 of the valve-casing is an oildischarge tube or pipe 29, which has its outer end screw-threaded to engage the internal screw-threads of the steam-regulating valve 30, which, as shown, has its other portion fiar- I00 ing with a flaring mouth or opening to receive the tapered valve 31 of the oil-discharge tube 29, which valve is detachably secured, by means of a nut 32, on the outer end of the valve-stem33, which passes through the tube 29 and the part 20 of the valve-casing. That portion of the valve-stem 33 which passes through the part 20 is screw-threaded, so that the valve 31 may be suitably adjusted to regulate the discharge of oil. As will be seen in Figs. 4 and 6 of the drawings, the valve 30 alfords a seat for the valve 31 and is provided on its inner surface with recesses 34 for a spanner or other instrument to be used for turning it on the tube 29, so as to regulate the discharge of steam through the steam-discharge tube or pipe 35, which, together with the portion 20, constitutes the valve-casing. The inner end of the tube 35 is externally screw-threaded to engage internal threads on a plug 36, which is secured into the outer portion of the part 20, as is clearly shown in Fig. 4 of the drawings. Secured to the plug 36 is an air-tube-37, which is formed with a series of openings 38 for the admission of air at its inner end and tapers toward its outer end. Secured to the outer portion of the air-tube 37 is'a tubular portion 39, which is provided at its outer end with external screw-threads to engage the internal threads on the nozzlepiece 40, which surrounds the oil and steam pipes or tubes and extends beyond the same, thus providing a mixing-chamber for the air, steam, and oil. As shown in Fig. 5, the innor. surface of the valve 31 is provided with a groove 42 to permit of the escape of gas from the oil-pipe should any remain therein when the said valve is closely seated.
,The operation is simple and as follows: Oil
' is admitted through the supply-pipe 18, from which it will pass through the tubes ll and 19 into the tube 29, from which its discharge may be regulated by adjusting the valve 31 in its outer end. When the oil has thus been admitted to the said pipes, steam may be supplied to the casing 10 through the pipe 23, from whence it will pass through the pipe 28 into the tube or pipe'35, from which its discharge may be regulated by means of the valve 30 at its outer end. As the steam surrounds the oil pipes or tubes 11 and 29, it is apparent that the oil in said tubes will be heated, and as the steam passes out between the valve 30 and the outer end of the pipe 35 with great force suction will be created, thus causing air to be drawn through the openings 38 in the air-tube and the oil to be sprayed or atomized at the outer end of the tube 29 and the steam, air, and oil caused to mingle or be thoroughly mixed in the mixing-chamber formed by the nozzle-piece 40, which also acts as a discharging-nozzle. It will also be understood that as the air-tube 37 surrounds the steam pipe or tube 35 the air within its tube will become heated by reason of its contact with the heated steam-tube, thus causing all of the elements-that is, the oil, air, and steamto be in a heated condition at and before the time of the mixing thereof.
It will be also understood that as the oil- tubes 11 and 29 are surrounded by steam generation of gas will take place as soon as the steam is admitted to the casing or body and whether the pressure of the steam be high or low the conditions of generation will be the same. It is further apparent that by the construction set forth the same steam used for heating the oil is employed to be mixed therewith as the latter is sprayed or discharged.
By providing the device with the enlarged or spherical-shaped casing 10 and placing therein an oil-retaining tube 11 of considerable size in such a manner that the steam may surround it it is obvious that the oil in said retaining-pipe will become excessively or super heated by reason of the heat from the steam, and as it, the oil, passes from the tube 11 into and through the oil-discharge pipe it will retain its heat by reason of its density and other peculiar qualities longer than the steam, and as the steam passes through the discharge-pipe 35, which surrounds the oil-discharge pipe, the said steam will be dried by the heat retained by the oil, thus preventing condensation and furnishing dry steam to the mixing nozzle or chamber, which is necessary for perfect combustion.
Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is
1. In an oil-burner, the combination with a casing, of an oil-conduit located therein so as to permit steam to surround it, an inwardlytapered valve located on the discharging end of said conduit and having a flaring opening, a valve-stem located in the discharging portion of the oil-conduit and having a tapered valve to fit in the opening of the first-named valve, a steam-supply pipe communicating at one of its ends with a source of steam and at its other end with the casing, the discharging discharging portion of the oil-pipe and having in its front end a flaring opening to receive the valve on the corresponding end of the oil pipe or conduit, an air-tube surrounding the discharging portion of the steam-pipe and having near its rear end a series of openings, a nozzle adjustably connected to the front portion of the air-tube and surrounding and projecting over the discharging ends of the oil and steam pipes or conduits, and means to regulate said valves, substantially as described.
2. In an oil-burner, the combination with a casing, of an oil-retaining tube or pipe located therein and communicating with a supply of oil, an oil-discharge pipe communicating at one of its ends with the said retainingpipe, means at its other end to regulate the flow therefrom, a steam-supply pipe communicating at one of its ends with a source of steam and at its other end with the casing, a steam-discharge pipe surrounding the oil-discharge pipe and communicating at one of its portion of the steam-pipe surrounding the v ends with the casing, means at its other end to regulate the flow therefrom, and an airtube surrounding the steam-discharge tube and having a series of openings near its rear end and a projection beyond its free end, substantially as described.
3. In an oil-burner, the combination with a casing, of an oil-retaining tube or pipe located therein and communicating with a supply of oil, an oil-discharge pipe communicating at one of its ends with the said retaining-pipe, a valve in its other end to regulate the flow therefrom, a steam-supply pipe communicating at one of its ends with a source of steam and at its other end with the end to said nozzle-piece, substantially as described.
