(Cl."li58'7) @Claims Ll This invention relates." toggas 'burning apparatus for; furnaces andthelike, and more particularly to a` conversiont burner to be ,employed in coal burning` furnaces. insubstitution' for the coal burning equipment.
One offthe objects of ".the.. inventionis Vto control the flow of gas Vandai'rfjin,a..1iarticularway because if the stream of air owingpast' the burner head is moving at high velocityland thereby sets up a condition of greatturbulence, a number of undesirable phenomena is to' be observed. One in particular is .that 'of`.preventing. the `spread of the fiame from/the burner head' to thushinder eiiicient transferof heat while another is the creation of undue combustionnoise Whichis un desirable.
` It will 'therefore be understoodthat another object of the inventionis. to. supply a substantially noiselessgas burning apparatus.
Apfurther object ,is to` supplya .unitary 4gas burning apparatus designed. to. .make furnaces, of limited heating areainto an' eicenthe'ating, unit comparable to specially' designed gasiirednnits. With thelforegoingi objects. outlinedendwith otherL objects; inview which vwill* appearaslthe description proceeds,` the invention.: consists in the novel features hereinafter .described in detail, illustrated inthe accompanying drawings, and more particularly pointedput in, the appended claims.
In the drawings:
Fig. 1v isv a diagrammatical4 vertical sectional View of a furnace with.-my.conversion burner installed therein.
' Fig. 2 is an enlargedouter end View of the. gas s.,
burning equipment.
Fig. 3 is a longitudinal` vertical' sectional View taken on the. line 3--3 of Fig. 2.
Fig. 4 is atopplan view of theinner, endLportion thereof.
.Referring tothe drawings 5V designates a conventional hot air furnace having an internal'casing 6 formingare box crjcombustionchamber 1. Ordinarily such furnacesV have a grate at the ,level 8. -.which separates the combustion chamber fromthe ash pit 9.
In accordancev'with the-present. invention, the grate is removed and my burner equipment it is inserted through the ash pit doorway il, after which the space between the ductvv I2v and the doorway is--closedby bricks i3; or the like.
As best shown in Figs. 2 and 3, the duct l2, which may be of sheet metal,fis in the form of an elongated hcx of-rectang`ularcross; lsection providedat its outerend with a: facejplatelli having a doorwayI l'for'theentrance ofair; In troduction of the airmaygberfcontrolled in any suitable way. For example, a. door i5a may be hingedly connected at l6` toY the. face plateand be provided with ears Handig] fLha'ving .threaded apertures to receive screws I9 and 2D which impinge upon portions of the face plate. It is ob- 2 vious'that turning off'the screws will result in opening or .closing the door and liolding'it in any desired position Vof' adjustment.
The face plate is provided with an outwardly projecting boss 2l' .through whicha v,gas supply pipe 22 .extendsinto the duct l2. `The inner end of saidipipe terminates adjacent the inner end 23 "of thev Aduct and'is provided with an" elbow 2li resting on achair vorbracket25,.secured tothe bottom of the duct. The bracket has a' notched horizontall arm 2S atits upper end for the reception of a short verticalV pipe 2l', having threaded` connection with the elbow.. A burner head 28 of special construction" has a threaded boss 29 at its'lower end; in'fthreaded :connection with the upper end of the verticalv pipe.
At this point, it will-be noted thatv thetop of the duct is provided with a .relativelylargebiiu cular openingA Siiinto whichthe` burner head extends, andV as the burner'head is arranged' centrally of sruch opening; an annular air `space 3i is provided' between the; burner head andi'the portion of .the duct defining the opening 30. 'The duct has smaller air dischargejopenings or? ports 32 arranged' atfopposite` sides' thereof, :andi an additional air discharge port 33'at thefin'ner end thereof. Due-to this construction, air introduced into the duct can be discharged into the furnace through all of saidports, vsome of thel air'travelling upwardly with the gas from the burnerlhead and other air being diifused through the' ports 32 and 33.
-Referringto Figs.; 3 and 4, vit vwill benotedthat the burner head has a frusto-'conical top 34.2.1'- ranged above the gas chamber 35,. whichy communicates with they depending hollow boss of the head; and within'such boss there is arranged a threaded plug 31 having an orificel 36"'through which gas passes into the4 burner head. As" the ping is threaded and removable fromtheburner head, it is obvious that plugs having different size orices may be substituted one for another to regulate the amount ofA gas intro'ducedzinto the bur-ner'head.'
The conical wall 33 of the top ofithe burner head is providedwwithvgasl discharge ports.' 39 which preferably radiate from" theY axis .of the burner head and extend upwardlyand. outwardly from the internal chamber of" such: head.
In accordance with the'finvention, .the burner head is provided with an upwardly and out'- wardly extending rim or annular Ishield 4B'to'prevent air from thel ductv from immediately' contacting the gas as the gas issues fronrthegas discharge ports.
In operation, gas is supplied through the pipe f entering the air duct at :or nearythe end upon may be caused to flow past the head. The flow of air for combustion is, partially past the rim of the head, and the function of the rim is to prevent contact of the air with the jets of gas emerging from the gas ports immediately upon emerging from the head. The intent of this arrangement is to stabilize combustion of the gas and prevent what is called blowing-off of the streams of gas or failure of the gas to ignite immediately upon emerging from the head.
If the stream of air owing past the head is moved at high velocity, rit will set up a condition of great turbulence to prevent the spread of flame from the burner and thus hinder` eicient transfer of heat while creating undue combustion noise. To counteract such tendency, I have provided the air discharge ports 32 and 33 at the opposite sides and inner end of the duct l2. The streams of air which flow through these ports enter the streams of fuel gently and by diffusion, at points removed from the head. Obviously, such air does not flow directly past the head as would be the ease with a single opening 39.
Through the provision of a plurality of openings or ports 32 and 33, the velocity of air flow past the head is reduced to such a point that noise of combustion falls to a suitable level, and the flame spreads to assure eiicient transfer of heat produced through the burning of the gas.
It is manifest that the radial width of the rim or shield 40 may be varied to obtain either completely diffused combustion or turbulent combustion in any degree required. Diffused combustion provides a highly luminous flame which is productive of a rich radiant heat transfer condition; however, a completely luminous flame requires more space for burning than is the case with increased turbulence and partially or completely blue flame.
As it is at times necessary to balance the space for burning the gas against the value of a luminous flame, I have thus provided means of controlling the type of combustion obtained, so as to retain as much luminosity in the flame as possible. Authorities agree, and it is well known to those versed in the art that a luminous flame is from two to seven times more ecient as a radiator of heat than is a clear or blue flame.
Any suitable means may be employed to ignite the gas from the burner head. For example, the burner head may be notched at one side, as indicated at 4I, and the notched portion may be provided with a depending lug 42 to permit the attachment of a pilot burner head to the gas burner head, by means of a screw 43 or the like. The pilot burner will be supplied with gas through a tube 44 that extends through the face plate of the air duct.
While I have disclosed what I now consider to be a preferred embodiment of the invention in such manner that the same may be readily understood by those skilled in the art, I am aware that changes may be made in the details disclosed without departing from the spirit of the invention, as expressed in the following claims.
