Wyatt, Columbus, Ohio Application April 16, 1947, Serial No. 741,781

6 Claims. (Cl. 158-114) The present invention relates to a gas burner assembly of improved type. A principal object of the invention is to provide such an assembly the required combustion for one double size radiant mantle. When using my burner assembly, the mantles are appropriately spaced along and above the'burners, being carried within the body of the heater in a manner which will be apparent to those skilled in the art, the disclosure herein being confined to the burner assembly,

rather than illustrating the remainder of the heater including the radiants referred to.

As an example of one use to which the present burner may be put, reference is made to my co-x.

pending application Serial Number 697 686, filed September 18, 1946, now Patent No. 2,517,071, which broadly discloses a type of heater in which the present burner assembly might be used.

It will be understood that the burner heads dis-.i closed herein may be putto other uses, such as for domestic water heating boilers, and for many other commercial uses. They may be used with many modifications of refractory elements or radiants, particularly when used in floor furnaces;

circulator heaters, for space heating, and various other commercial and domestic applications.

A very important object of the invention is to provide a burner having a mixing chamber and bale of novel design which avoids the necessity for a long neck venturi and burner throat assembly. As disclosed herein, the mixing operation avoids turbulence while providing an orderly mixture Without excessive pressure areas. The bale disclosed herein is formed to evenly distribute the mixed gas and air over the Whole length of the burner top Without turbulence.

One of the principal features of the invention is to provide a burner assembly comprising a selected number of burner elements, each burner element comprising two half castings of symmetrical design which are assembled and secured to one another face to face. The engaging faces of said half castings are machined to t one another and have appropriately arranged aligned ing chamber of the burner.

2 slots therein, said Vslots forming ports which provide uniform and complete combustion of properly mixed gas and air rising from the mix- It is an objective of the invention to provide a burner having a slotted top of such design as to provide maximum gas discharge.

The invention also provides a novel baffling arrangement within the burner heads, said arrangement comprising a bafe of novel design which is supplied as a separateelement, but which is assembled within the'burner head when the two halves of the latter are connectedtogether. The invention contemplates'a novel and simple arrangement for properly aligning-and connecting the burner halves vin position along and above the gas distributing pipe.'

Another important feature of the invention is a burner which provides 'for the supply of 4secondary air to the flame as it emerges from the top burner surface, and particularly to provide for'the supply of such secondary vair to central points with respect to the emergingflamefat a plurality of spaced points along the burner. This is accomplished by an arrangement lof secondary air slots at the burner top, which also provide a cooling n arrangement to prevent puff-back and back-flash explosions.

It is also an object of the invention to provide novel adjustable means for regulating the supply of air into and around the gas outlet nozzle from the distributing pipe of the burner. A further feature of importance is to provide orice plugs of novel design along the distributor-pipe, at and within each of the burner heads referred to.

It will be apparent that by reason of the novel construction referred to, my burners may be used effectively in confined spaces and may permit reduction in the height of heaters in which they are used. f

Various other novel and useful features of the invention will be apparent as the description herein progresses. While the burner'parts are referred to as being made of cast aluminum alloy or cast iron, formed in the symmetrical halves referred to, it will be understood that in certain instances it may be found convenient to make the burner halves of suitable ceramic materials. This is also true of the burnermixing battle.

Referring to Figure 2, the distributing pipe is shown at D, i-t being understood that this is the pipe which is customarily supported in the base of a gas heater, and through which the gas is distributed to the various burners. rlhe distributing pipe may be cut to any appropriate length, depending on the number of independent burner units to bel mounted thereon, as hereinafter de scribed. In any event, the distributing pine has connected thereto a gas inlet pipe I, preferably, centrally along the length thereof, and this inlet pipevor connection may be controlled by any suitable type of valve, such as one of the rotary plug type, and having provision for the connection of any suitable attachment, such as safety lighter attachments. For these purposes, and as shown in Figure 6, the gas inlet pipe connection is arranged extending downwardly at a, 45 angle from the horizontal plane passing through the axis of the distributing pipe.

Disposed at spaced points along the top of the distributing pipe are threaded openings iii, and it is over these openings that the respective burner units B are mounted. The burner units comprise a hollow chamber, formed for convenience of manufacture and installation in two vertical longitudinal symmetrical halves, the said halves being formed with cooperating aligned slots to divide the mixture of gas and air uniformly along the top of the burner as it is discharged to insure that maximum combustion is obtained. The burner units are designed to receive primary air into the lower part of their chambers and to mingle this air with gas entering their chambers from the opening I0, and to baiiie the mixture of air and gas as it ascends through the burner. This mixture of air and gas is discharged at the top of the burner where the llame is located and where secondary air is supplied at spaced points along each burner to accelerate the combustion of the mixture.

'As stated, the burner consists of symmetrical opposed half portions, each comprising a lower half saddle portion l 2 which is supported slightly spaced above the top of the distributing pipe, surmounted by a half cylindrical portion I4, the interior of which is hollowed out as at i6 to t over the head of a gas orifice plug (which is threaded into the outlet opening I0) and an outwardly diverging body portion 20 which is likewise interiorly hollowed outy as at'22 to provide a substantially diamond-shaped mixing chamber for the gas and air. A mixing baille L ismounted in the chamber 22 as hereinafter described. The interior of each burner is formed with a semicircular ledge 24 dening a somewhat restricted Venturi throat 26 centrally above the gas oriiice plug N. It will be understood that the inner faces of the burner halves are machined to evenly iit against one another to form the chambers referred to, as well as the discharge ports to be hereinafter described.

Referring to Figures 3 and 6, it will be noted that the walls of the burner units are so designed that the mixing chamber 22 is substantially rectangular in horizontal section, and that it widens outwardly above the throat 24 up to a point in horizontal alignment with baille L. Above this point, as indicated in Figure 6, the opposite walls of the burner units generally taper inwardly toward the top surface of the burner, where a plurality of gas outlets are formed by the symmetrical design of the two opposed halves of the unit. The top lips of the burner halves are so formed as to leave a continuous slot 32 throughout the length of'each unit. Inalternate sequence along the longitudinal slot 32, there are opposite relatively shallow transverse slots 34 :and relatively deep transverse slots 36 in the lips of the opposite sections, through which gas and air mixed in the chamber 2.2v may escape while being burned, thus providing a grid or grill-like top along each burner. In line with the relatively shallow slots 34, and on the outside of the burner sections,. are inwardly directed slots 3B, said slots being arranged alternately between the relatively deep slots 35, and having inner edges which terminate closely adjacent to the outer edges of the shallow slots 34, whereby secondary air is brought in a multitude of narrow channels inwardly to the center of the flame or burning area which constitutes they top of the assembled burner unit.

By reason of the above construction, the top surface of the burnerY unit comprises a web of 4 which join with transverse slots 43 to provide relatively small combustion areas at opposite ends of each unit, the slots 42 leading from the mixing chamber 22.

As best shown in Figure 2, the top edges of the burner halves are so formed that lateral channels 44 and 45 open outwardly along the burner top from Ithe deep and shallow slots t6 and 34 respectively.

It will be apparent that the method of forming the burner in half castings, as described, will permit the cutting or milling of the slots, as referred to, with convenience, accuracy and precision, and substantially all of the slots may be cut in one operation with a tool of proper design.

Similarly, the engaging faces of the burner halves may be evenly machined.

The inner faces of the burner units, at opposite ends, are provided with abutting anges 46 which contact one another, there being a circuitous groove 41 along said flanges conforming to the shape of the mixing chamber 22 within the burner unit, which groove is adapted to receive a welding rod 48 such as copper wire of the configuration shown in Figure 11. When the burner units are assembled as indicated in Figures l and 2, with the baffle L positioned in a chamber and with the respective welding rods 48 in the grooves 4l, the assembly may be set into a conventional welding fixture, clamped onto welding bosses 49 provided on the sections, and commercial welding equipment of well known type can be employed to automatically weld the units together. It will be understood that the units will be welded together before being assembled on the distributing pipe D.

The baille L is designed to insure an intimate mixture of the gas and air. It has longitudinally extending central end wing members 5l] (Figure 3) which serve to hold the baille between the opposed sections of the burner unit in vertical end slots 52 formed in the inner faces of burner halves on opposite sides of the chamber portion 22. Viewed from the top, the bafle tapers outwardly as at 54 from its ends toward its lateral center line, giving it a somewhat flat elliptical form, so that the rising gases will be evenly dis-tributed toward all walls of the chamber 22 of the burner unit including the end walls 55 thereof and into the corners 56. side of the baille, its top surface is downwardly concave as shown at 53 in Figure 2. In transverse cross section, the baille is substantially diamond-shaped and the top surface of the baille slopes gradually upwardly on each side of its longitudinal center lines as at 6l) to the longitudinal downwardly concave center-line 8D. It will be noted in Figure 6, that the widest portion of the baille is in a vertical plane substantially at the level of the widest lateral portion of the chamber 22. With this arrangement, the mixture of gas and air rising upwardly will be caused to mix intimately before exiting from. the top of Ithe burner, being deflected outwardly in the chamber 22 through the length of the baille, and toward all walls of said chamber including the end walls thereof. After passing around the side edges 62 of the baille, the relieved upper face thereof permits the combined gas and air to flow freely into the center of the burner, whereby it may pass upwardly through the central continuous longitudinal port 32, the outwardly directed portions of the mixture passing freely upwardly along and adjacent Ithe walls of the chamber 22 and exiting through the ports pro- Looking inwardly toward theI vided by the adjacent shallow and deep slots 34 and 36 respectively. It will be apparent that when a flame is applied to the top'of the burner units, a hot re will be present over the entire top surface thereof, same being fed by gas and air mixed in the chamber 22, with further secondary air being added throughout and within the area of combustion by the rising of air in the exterior slots 38. The burner formed as described comprises a top grill-like surface of staggered ports, and a side radiator-like wall which provides for the rise of fresh air to the combustion point, as well as providing for cooling the end of the burner to prevent puff-back and backflash explosions.

rIhe gas orice plug lll has a threaded lower end 'lll with an enlarged bore 'l2 therein, and a .top flange i4 of wider diameter than the threaded part 1li having a restricted nozzle opening 16 therethrough. Referring to Figures 3 and 17, it will be observed that the flange H4 is not continuous, but comprises spaced radial outwardlyextending arms 18, separated by relatively wide spaces, whereby the outside air may freely rise through the space 8E! (Figure 6) between the saddle portion I2 of the burner and the outer wall of the distributing pipe, and upwardly through the inlet chamber I E where it joins with the gas from the nozzle opening 15. The initial mixture passes through the restricted Venturi throat .24 of the burner. The effectiveness of the mixture is insured by the outwardly and inwardly deiiected rising action previously described in connection with the design of the baillemember L, whereby the mixture is in proper condition for complete combustion when it discharges from the top of the burner.

The gas orifice plug N meters both primary air and gas and is made to suit the gas specifications of any particular area or application. The outer rim of the plug is notched in accordance with the amount of air required, and for the application of an appropriate socket wrench to `secure or remove the plug. The neck chamber l5 of the burner ts over and around the air ports provided by the outside notches in the plug. The skirt l2 of the burner extends downwardly to the center line of the distributing pipe to prevent turbulence by cross air currents or drafts across the floor.

The orifice 'IG in the plug N is drilled in accordance with the E. t. u. characteristics of the gas to be used. `When the plug characteristics are established, as to volume of air (by size of outside notches) and gas (by size of orifice '(6) for a given locality or application, no service or adjustment is needed, although obviously the plugs may be replaced with others of different characteristics as necessary.

The edges of longitudinally adjacent burner unit halves are provided with semi-circular cutouts 84, as shown for instance in Figure 2, and appropriate stamped metal clamping members C are disposed on opposite sides of the assembly and locked to one another by bolts 8G which thread into an opposed bolt head 88 as shown for instance in Figure 5. The bolts pass through the clamping members and through the openings formed by the cut-outs 84. The clamping inembers C have inwardly turned upper ends 90 which engage the end flanges 4@ of the burner halves, and lower ends provided with webs 52 which clamp around the discharge pipe, as shown in Figure 5. With this construction, the various previously assembled and welded burner units (formed of their' two halves) are held in proper position along and above the distributing pipe, in register with the outlet openings lil and gas plugs N, and with the saddle-like air hood l2 spaced above the distributing pipe to provide the air space Se through which air is caused to riseand mix with the gases as previously described.

At each end oi the assembly, the clamp C locks the outer end o the sections of the end burner together in a manner similar to that just described, the parts of this clamp also contacting opposite sides of the shank Idil of an end bracket member R, the lower end of said member having an eye itl therein of size to embrace the distributing pipe, and being held against the end of the distributing pipe by a nut |2 having an inner end lill; threaded into the end of the distributing pipe. The top end lil of the bracket R may be formed in any appropriate manner to support the entire assembly on the cooperating parts or fra-me oi the gas heater with which this burner arrangement is to be employed.

While I have disclosed a preferred :formy of the invention, from a manufacturing standpoint, as comprising burners fabricated individually from halves which are assembled and welded together, it will be understood that two or any plural nunk ber of the burners may be formed of connected multiple half portions in the manner illustrated, for instance, in Figures '1, 8 and 9. In these iigures, the design from an operating standpoint is substantially the same as 'that previously described, except that the end flanges |538 of adjacent burner halves are connected together, so that one casting forms a half portion of several burner units. As shown in Figure 8, these burner half portions are equipped with a lower depending semi-cylindrica1 hood-like member lib which overlies the distributing pipe D, there being supair space under the hood, so that primary air may 5 rise around the gas oriiice plug and through the small interior chamber H5, and thence into the larger mixing chamber llt beneath the baille L. The multiple half burner portions are provided with the grill-like gas outlet openings along the top burner surface in the same manner as described in connection with the principal embodiment of the invention, except that intermediate slots i il' all provide for discharge of gas between the main burner portions, these slot-ports being fed by passages l it from the mixing chamber I it. Disposed along the length of the multiple half burner portions, and between the burner units. thereof, there are aligned openings through which are passed bolts i9 to secure the half burner portions together. At opposite ends of this assembly there are vertical aligned grooves |255 of the 4configuration shown in Figure 8, thus forming end sealing seats in which a gasket or furnace cement may be disposed when the parts are assembled and connected together, to form end seals at opposite ends of the assembly. The ends of the half castings may be formed to provide extending lugs 12| to support the assembly on the base of a heater. Gas may be admitted to the distributing pipe through one end thereof, the opposite end being closed by a cap |22. In all other substantial respects, the arrangement disclosed in Figures 7 through 9 is the same as that described in the principal embodiment of the invention.

Referringto Figures 14 through 16, a further modication is shown wherein controlled primary air supply is substituted for the air supply provided by the hoods l2 in the case of Figure 2 or the hood Hu as in the -case of Figure 8. In Figure 15, the multiple opposed burner halves |30 pass downwardly entirely around the distributing pipe D as shown at |32 providing an aii` space ist around the distributing pipe. In the bottoni of the multiple burner units thus formed there are a plurality of longitudinally aligned air inlet openings |35, and a damper plate |38 is mounted for longitudinal movement beneath opposed longitudinal ledges M. The plate |38 is provided with longitudinally spaced openings |42 which are adapted to be moved into and out of register with the openings it` to regulate the amount of air which can pass into the space |34 around the distributing pipe D, and thence upwardly through the throat |37 into the mixing chamber beneath and around the baille L. In a manner similar to that described in Figure 8, the multiple burner sections are held together by spaced lateral bolts Mil, and at opposite ends, there are appropriately formed end locating and clamping washers M6 and |48, the former having an opening lds therethrough for the distributing pipe and the latter being closed and threaded onto the protruding end of the distributing pipe D. at the inlet end of the distributing pipe, an exterorly threaded sleeve |58 is held against the clamp it@ by a nut 52 threaded onto the end of the distributing pipe.

Means are provided for adjusting the register plate 33 longitudinally of the distributing pipe, comprising an operating arm |5ll passing longitudlnally through an opening |56 in the end clampand having an upwardly turned end |58 which passes through an opening ld in an end |t2 on the plate |38.

Threaded for longitudinal movement, on the sleeve |553, is an adjusting nut |65, this nut having a circular track |66 therein, in which rides a disc Ill) on the end of the operating nut ld. The disc |15 rides in the track |66, and inward and outward movements of nut ltd are translated to the rod |54, thus adjusting the plate |33 longitudinally in the lower part of the chamber between the half sections of the burners, to adjust the degree of alignment of openings |35 and |552. As in the embodiment of Figure 8, there are end sealing grooves |712, for the reception of gasket material or cementl to seal the opposite ends of the burner assembly. In this embodiment, a gas oriiice plug N of design omitting the outside air metering notches is shown, and the chamber |355 has spaced tapered outlets l'li leading to the throat I3?, around this plug. Obviously the plug and chamber arrangements of the other embodiments could be employed, but in this embodiment, the air is controlled by the damper arrangement described. In all other respects, the emm bodiment last described is similar to that of the preferred embodiments.
