This invention relates to oil burners of the gravity feed type. v
An object of this invention is to provide an oil burner which while designed for use in tobacco drying apparatus will provide'a'n efficient burning of oil, and can be used in boilers, furnaces or other heating equipment.
Another object of this invention is to provide an oil burner which includes a plurality of superposed shelves or traysov'er which the oil isadapted to flow, the excess or unburned oil engaging on an upper shelf 'or tray dripping onto a succeeding shelf or tray, the shelves for trays being so constructed and "arranged, and of such number that all of the oil will be burned.
A further object of this invention is to provide an oil burner of this type wherein the inflowing air will effect a spreading of the oil onto the burner plates or trays and cause vaporization of the oil as the oil drips from one burner plate to another.
To the foregoing objects, and others which may hereinafter more fully appear, the invention consists of the novel construction, combination and arrangement of parts, as will be more specifically referred to and illustrated in the accompanying drawings, but it is to be understood that changes, variations, and modifications may be resorted to which fall within the scope of the invention as claimed.
In the drawings:
Figure 1 is a longitudinal section of an oil burner constructed according to an embodiment of this invention.
Figure 2 is a sectional view taken on the line 2-2 of Figure 1.
Figure 3 is a sectional view taken on the line 33 of Figure 1.
Referring to the drawings, the numeral 56 designates generally a housing which is formed of top and bottom walls I I and I2 and opposite side walls I3 and I4. The housing I8 is provided with supporting feet I5 which support the housing above a plane surface. The top wall I I is formed with upwardly extending side flanges I6 against which the side walls I3 and M are adapted to be secured by any suitable fastening means and the inner end of the top wall H is formed with an upstanding flange H. The housing H3 is open at each end and the front end of the housing 2 I1) isadapted to be selectively closed by means of a door or hinged closure I8 which is pivotally mounted on ears iQcarried by the housing 1. The housing '59 also includes in the forward porltion thereof a collecting chamber 2i whichis formed by offsetting downwardly the forward portion of the housing and the chamber 26 is adapted to be connected by 'means of'a pipe 25 to a rece'iver or the like. The top wan Hhas secured thereto 'a fuel discharge pipe "22 which-is adapted to discharge fuel into the forward portion of the housing. H The side walls I3 and it are each formed with vertically spaced supporting flanges 23, 24 and 25 which terminate at their inner ends in upward-1y projecting flanges or stop members 26, 21 and 28, respectively. An oil distributing upper plate 29 is disposed on the upper support comprising the flange 23 and 26 and an intermediate oil distributing plate 3!! is disposed on the intermediate support comprising the flanges 2i and 21. A lower oil distributing plate 3| is mounted on the lower support comprising the flanges 25 and 2B and these oil distributing plates are preferably of increasing width from the uppermost to the lowermost as shown in Figure 1. The upper surface of the plate 29 is inclined downwardly and forwardly as indicated at 32 and an oil retaining rib 33 projects upwardly from the forward edge of the plate 29. The rib 33 is of a short length and the side edges thereof terminate in spaced relation from the side walls It and i i. The top surface as of the plate 3i; is inclined downwardly and forwardly and an upwardly projecting oil retaining rib 35 projects from the front portion of the plate 30. The rib 35 is of a greater length than rib 33 and the ends are spaced from the walls I3 and I4. The lower plate 3| is formed with a downwardly and forwardly projecting upper surface 36 and an upwardly projecting retaining rib 3i is carried by the front edge of the plate 3|. The rib 3'5 is of a greater length than the rib 35 and is spaced from the walls I3 and I4. The upper surfaces of the oil distributing plates are inclined downwardly and toward the front of the housing H3 so that the oil overflowing from the upper plate 29 and dropping onto the intermediate plate 30 will by reason of the inward draft of air through narrow slots 38 formed in the door or closure I8 cause the oil to become partially vaporized as it drops and the globules of oil which drop from one plate to the other will be carried inwardly of the housing by the force of the inwardly moving air. This inwardly moving air not only assists in distributing the oil over the surfaces of the plates 29, 30 and 3| but also provides air for mixture with the oil vapors for combustion purposes. The oil which finally drops from the lower plate 36 enters the verflow or collecting chamber 20 and from this chamber is drained to a suitable receiver.
The inner portion of the housing H1 is provided with a refractory lining 39 terminating at its inner end in a refractory flange 40 which overlies the inner end of the housing [0.
In the use and operation of this burner the oil is discharged from the fuel pipe 22 by gravity onto the upper burner plate 29. It will be understood that the supply pipe 22 may have a suitable regulating valve interposed therein for properly regulating the discharge of oil onto the upper burner plate 29. The oil may be lighted in any conventional manner and in the event there is not suflicient inflowing air entering the housing through the air intake openings 38, the door l8 may be swung partly to open poistion to admit additional air into the housing l0. By having the upstanding short ribs 33, 35 and 31 on the respective burner plates the dripping of unburned oil from one plate to another is retarded so that the oil on one burner plate will burn to the greatest degree possible. This burner has been designed particularly for use in tobacco drying apparatus but can be used for other purposes such as in boilers, furnaces or other heating equipment.
What I claim is:
An oil burner comprising a housing open at each end, a closure hingedly carried by the front end of said housing formed with a plurality of vertically spaced apart horizontally elongated air intake slots, a plurality of horizontally disposed burner plates, each of said plates having the upper surface thereof inclined downwardly toward the front end of said housing and the front edges of said plates being progressively oifset rearwardly from the lowermost to the uppermost plate whereby excess unburned oil on an upper plate will drip onto a lower plate, an oil supply pipe disposed above the uppermost of said plates and adapted to discharge oil thereon, an oil retaining rib carried by the front edge of each plate, each of said ribs being of less length than the width of its associated plate and of progressively increasing length from the rib 0n the uppermost to the rib on the lowermost of said plates whereby oil flowing on said plates is caused to flow around the ends of said ribs, means supporting said plates in superpose spaced relation and in substantial alignment with said slot whereby the air entering the housing through said slots will pass over said plates and effect a distribution of oil on said plates,
