OIL-BURNING APPARATUS.
Specification of LetterS'Batent. Patented Apr.. d, 1922..
Application mea my 11, 1.920.1 serial no. 386,605.
To all whom t may concern'.
Be it known that I, DANIEL E. ERICKSON, a citizen of the United States, and residing in Mamaroneck, in the county of Westchester and State of New York, have-invented certain new and useful Improvements in Oil-BurningApparatus, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and Vuse the same. A
This invention relates to fuel-oil` burning apparatus, and more particularly to improvements in oil-burners especially adapted for steam-boiler furnaces.
It is an object of the invention to provide an eicient and practical oil-burner of the character mentioned.
Itis a further object to provide an improved apparatus whereby the fuel-oil is insured thorough volatilization'and the combastion is edected with a proper, and regulable volume of air. Another object is to provide an apparatus for the purpose set forth which is capable of ready adjustment to operate at maximum eciency under dierent conditions, and is further capable of convenient assembly and dis-assembly when required.
Broadlyit is the object of the invention to provide an improved oil-burning apparatus having lfeatures of structural superiority and functlonal advantage. e,
Other objects and advantages vwill be noted hereinafter in connection with the following description of the accompanying drawings, which'illustrate a preferred embodim'ent o f the invention, andl wherein Figure lis a'central sectional view of the burner apparatus, taken on the line 1--1 of Figure 2.
Fig. 2, 1s a front view thereof, with ce1*- tain of the forwardly extending parts cut off and shown in section.
Fig. 3 is an enlarged view of certain of the apparatus illustrated in Fi re K2.
Fig. 4 is a section on the -ine 4:-4 of Fig'.
ig. 5 is a fragmentary side elevation -of the outer enday of the device.-
Fig. v6 is a 'section at the burner tip on line 6 -6of Fig. 3.
Fig. 7 is an end detail view of the deflector, exposing the baffle vanes through the air inlet, and
Fig. 8 is a side'sectional elevation of Fig. 7 taken on the line 6 6 thereof.
Referring. more particularly to the drawings, there is represented a part of a furnace front 7 having a circularopeningS and an'r interior casting 9 secured thereto andA affording a conoidal chamber 10 that expands inwardly from the opening 8; The oil-- burning apparatus comprises, in general, a unitary assenibl applied, and preferably hinged, to the urnacafront concentric to' cylindrical and has an open outer end 14 save for spider arms 15 which join the same wlth a materiallysmaller circular eX- tremity 16 having y acentral' bore 17 there'- through. rlhe inward' portion of casing 11 has the centering interior surface 111- for directing the flow of air centrally toward.
thel furnace entrance. The casing end 16 constitutes the sup ort for a tube 1 8 extending through bore 1 and projecting inwardly to about the plane of the opening 8 in the furnace front. Tube 18 in turn is held by a set-screw 19 and its outer end is'threaded to receive a hollow nut 20 which releasably holds a block 21 with a conduit 22 connecting the fuel supply pipe' 23 and the discharge pipe 24.- The lattervis supported by` block 21 and, extending axially within tube 18, is provided withl a terminal burner tip volatilization of the oil, supplled preferably preheatedand under pressure.
25. The burner tip/ is of character to effect" At the inner end of tube 18, there dis also provided a surrounding flared element 2'6 which is longitudinally positionable and 'l 4functions-as an air delector and lame cone.
This element, in the construction shown, has' attached theretoa pair of rods 27 extending parallel to the tube 18 and outwardthrough casingextremity'l to terminate in ing a central opening 31, at its smaller end,.
and having an inturned flange 33 at its larger end to co-act with the front surface 34 of an annulus 35, that is secured to the furnace front by bolts 36, said element 30 being movable along the tube 18 as by a second pair of rods 37 which protrude outwardly and terminate in handles 38, whereby element 30 is capable of independent adjustment to control the volume and 'force of the draft of incoming air, whereby the character ofthe combustible mixture may be governed.
The conoidal element 30, which, it will be noted, opposes its base or larger extent to the furnace opening. 8, thereby constitutes a chamber for pre-heating the air supply that enters at the orifice 31. The flange 33, which is in the form of an annular inturned lip, presents its outer surface'33a in opposition to the outer surface portion 34 of annulus 35, at acentering angle, said surfaces 33a and 34 being in substantially concentric parallelism, to thereby accord a centering or conoidal formation to the volume of air flowing into the furnace from casing 11. It will of course be appreciated that the volume of air thus introduced, as well as its speed of travel, are regulable by the transverse extent of the passage between surfaces 33"l and 34, said extent being adjustable through the axial movement of member 30.
The conoidal member 30 is slidably mounted on tube 18 by a collar 30a,v which connects with memloer-v 30 by radial or spider arms 30". vAlso carried by collar 30*1 is a series yof radial, angularly disposed vanes 30, that ex-l tend transversely between the opening- 31v in member 43 0 and the furnace opening, thus serving 'the vtwofoldlpurpose of causing air that passes to the furnace through opening 31 to have a whirling motion, and also comprising a baffle which prevents the direct radiation of furnace heat out through opening 31. In effect heat is by this means conserved within member 30, which thus becomes apre-heating chamber for -the air supply that enters through opening 31, thereby enhancing its combustion'supporting efficiency. The air deflectin-g element 26 which surrounds the burner tip may be provided with openings,.here shown in the form of slots 41, to permit some of the preheated air from member 30. to enter within the conoidal chamber of element 26, tothus aid 'in the support of combustion near the ame genesis, where the -burner tip is supplied with air by supply entering through tube 18.
The. technical effect achieved in improved combustion b thus intermingling the air y annulus at its entrance, 1n combination, a
supplies 'in the region of flame generation is important, and, I believe, new with me'in the art.
In operation oil is projected into the combustion chamber through the burner tip 25 and in a finely divided state forming a combustible mixture with air which enters through tube 18, vthrough casing 11, around and through conoidal` member 30, and through the slots in member 26. The adjustment of said member 30, and the independent adjustment of the member 26, as described, enables a regulation and fine control of the course of incoming air and thereby the relative proportions of air and oil in the combustible mixture as well as the shape and length, to an extent, of the burning flame. withdrawn its full length from the furnace it closes the air intake to casing 11, and constitutes a door shutting off the passage of air to the furnace.
It will thus be observed that the apparatus as described attains, among others, the objects and advantages before noted. It is to be understood, however, that the invention is capable of modification without departing from the intended scope of the following claims.
Having thus described my invention, what yI claim as new, and desire to secure'by Letters Patent is: n
