Application July 14, 1947, Serial No."zs0,9'01
(o1. 15s 99) I simplifying installation and assembly of the.
burner units.
Other objects ofthe invention are to provide highly efii'cient burner units having flame discharge across secondary air inlets through the hearth and to'p'rovidea burner and hearth struc- "turewhich facilitates removal and repair of the burner parts. It is also an object of the invention "to provide an upright burner body having a burner head provided with an annular fuel mixture outlet and a platform or hearth having an opening of larger diameter than the head and forming "an annular outlet for secondary air substantially at the fuel mixture o'utlet opening of the burner head.
Inacc'omplishing these and other objects of the -invention hereinafter pointed out, I have provided improved structure, thepreferred form of which is illustrated in the accompanying drawings wherein:
Fig. 1 is a vertical section'through 'a portion of a hearth and burner unit constructed in accordance with the present invention.
Fig. 2 is a plan view of 'a hearth made up of a plurality of platform sections, each of which is supported by a burner unit.
Fig. 3 is a side elevational view of the inlet end of a burner unit showing the mounting thereof units 2 which are constructed in accordance with the present invention. Each burner unit includes a tubular body member 3 having bell-shaped air inlet ends 4 and upwardly tapering outlet ends 5 for forming a flow passageway having a Venturi throat E.
The edge of the bell-shaped inlet is provided on'diametrically opposite sides 2 thereof with depending lugs I having seating faces 8 conforming to the upper faces of the ducts on which the burners are mounted. For example, in the illustrated instance the fuel supply ducts are of substantially cylindrical cross section and.
the faces 8 of the lugs are of corresponding arcuate formation to seat the tubular body on the duct in encircling relation with a fuel discharge-nozzle 9 later described. Extending across the bell-shaped inlet intermediate the lug 1 is a yoke I9 adapted to extend under the fuel supply duct and which is provided .with an internally threaded opening H to mount a clamping device such as a set screw l2 which is adapted to draw the seating faces of the lugs 1 against the duct to rigidly support the tubular body of the burner thereon. The'dis'charge end of the body member is provided below the outlet end I3 thereof with an annular flange I 4 having upper and lower stepped shoulders I5 and IE to provide annular seats for a spider I! and a burner head Hirespectively.
The spider l7 includes a ring-like portion l9 which encircles the tubular body of the burner and is supported on the shoulder i5 as best shown in Fig. 1. Extending radially from the collar portion of the spider are lateral arms 23 having upper'edge faces 22 offset from the upper face 2'! of the ring portion [9 for seating a platform se'ction 23 later described.
'Ihe burner head l8 includes a collar member 24 having an upwardly and outwardly tapering annular periphery 25 and an inner bore 26 for closely engaging over the discharge end of the tubular body of the burner. The upper portion of the bore of the collar is outwardly tapered to provi'de an annular face" 27 which is encircled by an outer beveled face 28 on the peripheral edge of the collar.
2'8 designates a burner cap or cover comprising a substantially inverted cone, the conical surface 3!? of which is at an angle to the flaring face 27 of the collar member to provide an annular pass'ageway 3i therearound which is directed outwardly and upwardly and which tapers toward the outlet to maintain velocity of the fuel mixture, the passageway being maintained by supporting the cap from the ring-shaped head on lugs 32 which in the illustrated instance are formed as a part of the cap as best shown in Figs. 1 and 5. The apical portion of the cone-shaped cap is thus carried in coaxial relation with the passageway through the tubular body'for divid- 11;; and diverting the fuel mixturefor even flow through the annular passageway 3i. Th'cir cumference of the cap is preferably beveled as at 33 corresponding with the bevel of the collar members of the head as shown in Fig. 1. The collar and cap portions of the head are preferably formed of a refractory material for resisting heat of the flame when the burner is in operation.
Each platform section includes a substantially fiat rectangular block 34 having rabbet edges 35, the rabbets on one edge being arranged reversely to the rabbets of the opposite edges for interengaging with adjacent platform sections carried on the spider of adjacent burner units. The spider member I! of each burner unit is supported on the tubular body and the platform sections are of a thickness so that the upper faces thereof substantially register with the annular outlets of the burner heads and provide a hearth for the firebox in which the burner units are installed.
Each platform section is provided with an open ing 36 of larger diameter than the collar portions of the burner heads and which are tapered corresponding to the taper of the heads to provide upwardly and outwardly extending annular passageways for discharge of secondary air in close contact with the jets discharged through the fuel passageway 3 l, the secondary air passageway having inlet between the arms of the spider so that air from below the hearth may move uniformly in encircling relation with the burner heads.
The nozzle 9 is of tubular shape and has threaded ends 31 engaged in threaded openings 38 which are located at suitably spaced intervals along the length of the fuel supply ducts. The nozzles may be furnished in different lengths relatively to the Venturi throat so as to provide the proper mixture of primary air and fuel when the burner is in operation. The primary air is admitted through the openings formed between thebell-shaped inlet and fuel supply duct as shown in Fig. 1.
In installing burner units in a firebox sufficient burner units are provided to generate the required heat. rows with the units in each row connected with and supported on a fuel supply duct, the ducts being supported in any suitable manner. The tubular bodies of the burners are mounted on the fuel supply ducts by sliding the yoke portions over ends of the ducts and locating the bellshaped inlets concentrically with respect to the threaded openings 38. The burner body members are then supported in fixed relation with the ducts by tightening the set screws l2. The burner y nozzles are inserted through the upper ends of the tubular bodies and turned into the threaded openings of the ducts. A spider IT is then applied over the discharge end of each tubular body member so that the ring portions 19 thereof seat upon the shoulders I5 as shown in Fig. l. The platform sections are then placed on the spiders so that they are supported on the arms thereof with the rabbet edges of one section interengaged with the rabbet edge of an adjacent section to provide a closed hearth with the exception of the openings in the respective sections. The collar members 24 of the burner heads are then passed through the openings of the platform sections to seat upon the shoulders it after which the cap members 29 are applied with the lugs 32 thereof supported on the outwardly flaring end faces 21 of the collar portions of the burner heads.
When the burners are in operation the fuel delivered to the ducts is discharged through the The burner units are arranged in nozzles 9 and the draft through the firebox causes primary air to move through the bell-shaped inlets of the burner body members to mix with the fuel discharged through the nozzles so that a combustible mixture is discharged through the upper ends of the tubular bodies and distributed by the cone-shaped cap members 29 for uniform flow through the annular passageways 3! while secondary air is being drawn through the passageways formed by the openings of the platform sections.
From the foregoing it is obvious that I have provided a burner structure wherein the platform sections composing the hearth are adapted for support on the tubular body members of the burner units which in turn are carried on the fuel supply ducts. This construction facilitates assembly of the burner units and hearth supported thereby and assures an adequate supply of secondary air for completing the combustion of the fuel mixture discharged through the passageways of the burner heads. It is also obvious that the structure facilitates removal and repair of the burner parts including the platform sections of the hearth.
