One particular and important embodiment relates to a combined gas burner. andawater heater. Another particular and'important 19 embodiment relates to the combination of my improved gas burner with the conventional furnace normally adapted for An object of my invention is the provision of a gas burner which achieves a high degree, I of efficiency and produces substantially complete combustion free from the collection of a deposit, in combination with heatingme'ch anism suchas a water heater or the fire pot of a furnace. The heater and I combustlon chamber are so relatively arranged that the heat is most effectively used and developed to be applied to the heater.

Another object is the provision of'a comofsimplereadily disassembled for cleaningpurposes or substitution of various heating elements;

Another object is the provision in a fur-- nace of conventional design of an adaptation of my improved burner, which effectively heats the furnace wall as desired, and wherein a plurality of gas burners may be supplied Y in individually controlled units.

A meritorious characteristic of my improved gas burner is thatI provide a manie fold which'receives gas fuel through asuitably controlled intake and discharges the same through a pluralityof minute nozzles,

in combination with a mixing chamber which receives the fuel mixture throughfa series of Venturi intake tubes corresponding in number to the discharge nozzles in the manifold and arranged directly 'thereover but spaced therefrom to admit air into the fuelstream to enter the mixing chamber, and wherein the mixing chamber is suitably provided with outlet orifices for the fuel mixture which lead into a combustion chamber.

Figs. 6, 7, and 8 are perspectives of the baffle plate, mixing chamber and manifold,

respectively, of my improved burner sepaof two sections each indicated by the numeral 16 and each provided with a series of Venturi tubeintake elements 18. A tubular intake-element 18 is provided foreach discharge nozzle 15 and the mixing chamber sections are supported so that the tubular intakes are positioned above the discharge nozzles and in Figs. 1 and 2 the mixing chamber sections and the manifold are shown as pr0- vided with flanges 20 between which are positioned spacer elements 22 and the assembly is held together by bolts 24:.

'The combustion chamber space or zone is between the two sections-16 of the mixing chamber and the fuel mixture enters this space through discharge orifices 26, a plurality of which are providedin the opposite faces of these mixing chamber sections. Auxiliary air is permitted'to enter the combustion chamber spacein any amount desired through the use of the perforated slide valve plate 28 which has apertures '30 arranged therealong. This slide valve is disposed to I travel over flanges 32 formed on. the opposite faces of the mixing chamber sections 16.

The mixing chamber sections are provided at the ends with ears or flanges 34 which extend partially across the combustion chamber space as indicated in Fig. 2 and end plates 36 are secured theretoby bolts 38 and extend upwardly therefrom to support a top plate 40 which has an outlet42 for the products of combustion and forms withthe side plates 44 an enclosure about one or more heating ele-, .ments. The two side plates are removable and are merely inserted at the top underneath the side flanges formed on the top plate 40 and on the bottom inside of ears as formed on the 5 on the outside and an asbestos sheet 52 posi tioned between'the finish plate and the body portion of the plate 44.

The heating element is here indicated as comprising upper and lower header elements 54 communicating with each other through 0 vertical water tubes 56. The side plates are shown as provided with ,baflie elements 58 which partially embrace the water tubes and with heat retaining vertical fins 60 extending between the water tubes.

In the operation of the structure the gas fuel is discharged through the nozzles 15 from the manifold and passes upwardly through the intake tubes 18 into the two sections of the mixing chamber and is there mixed with air which is taken in through the tubes 18 and this fuel mixture discharges into the combustion chamber space between the two sections of the mixing chamberand additional air is admitted into such space through inanipulation of the slide valve 28 and the productsof combustion pass upwardly into the enclosure 7 formed by the end and side walls heretofore described to be suitably exhausted. The mixing chamber sections become substantially red hot during combustion and the fins 60 likewise become very hot and the combustion operation is thorough and complete and a high degree of efliciency is attained; It will be apparent that though a. water tube heating ele+ 7i ment is here shown that it would be possible to employ an air heating element if desired. In the embodlment of my lnventlon for furnace use the clrcular wall of the fire pot is indicated at 70 and theusual grate bars at #3 72, and in Fig.5 I have shown a plurality of my improved gas burner units located in substantially spaced apart relationship and supported on the grate bars 72. Four units are here shown and each unit indicated in the assembly at 74.- is connected with a gas supply pipe 7 6 through an individual inlet pipe 78 which is individually controlled through valves 80.

Each gas burner unit comprises an intake manifold 82 having an upwardly extending ridge portion 84 which is provided with a plurality of minute fuel discharge nozzles 86.

Positioned above the manifold is a mixing chamber. .The mixing chamber comprises a mixing chamber portion proper indicated as 88 and which communicates with the manifold to receive fuel therefrom through a portion. formed by two complementary castings 90 held together by b'olts92 and adapted, as

shown in Figs. 3 and 4, to straddle the ridge passageways 94., one for each discharge nozzle of the manifold positioned thereaboveto receive fuel therefrom and that casting which is opposite thefurnace wall is cutaway as at 96 providing an air inlet 98 wherein air is drawn to enter the fuel stream to pass upwardly through the passageways 94 into the mixing chamber 88. i 1 V I The mixing chamber supports a bafiie plate 99 which is provided with two prongs, or lugs, 100 that extend through apertures provided in thetop wall of the mixing chamber to sup port the baffle plate and is provided with wings 102 at the ends and with lugs, or projections, 104 one at each end extending toward the wall of the furnace to support the baffle plate thereagainst. The baffle plate has an upper marginwhich is curved as shown in Fig. 5 of the drawings but is spaced from the furnace wall. supported as described upon the mixing chamber so that it may be taken off to facilitate cleaningof the discharge nozzles of the mixing chamber.

The mixing chamber has a curved face arranged opposite the wall of the furnace and a series of discharge nozzles 106 through which the fuel mixture is discharged toward the Wall of the furnace and into the space be tween the baflie plate and the furnace wall.

It is deflected by the baflle platetoward the furnace wall tomaintain the same in a highly heated condition.

In a construction of this type it is ap-" parent that each burner may be operated individually and apart from every other burner so that only that amount of fuel need be used depending upon the amount of heat desired to be produced and that that portion of the furnace wall which is heated will be highly heated and the combustion will be substantially complete.

The fuel is drawn into the mixing chamber ventional furnace provided, with grate .bars, a plurality of individual gasxburner: units having individual fuel inlets individually 1 through the tubular intakes andmixed with air entering through the inlet 98 which is also drawn upwardly into the mixing cham ber and the highly heated condition ofthe This bafile plate'is movably.

ber shown in Fig. and the mixing chamher in turn supports-the baflie plate shown in Fig. 6. The mixing chamber is removably mounted upon .the'manifold andthe lower forked portion straddles the ridge on the upper face of the manifold to position itself thereon. The baffle plate has lugs Whichare received in recesses formed adjacent to the rear edge of the mixing chamber in its upper face and is therefore removably supported upon the mixing chamber. This type of 'con-' struction facilitates'the assembling and disassembling of the unit which makes the cleaning of the same more easy.

It is apparent that the air whichrises up through the grate bars and passesalong the furnace wall and over the manifold and mix- I ing chamber becomes very hot-before it enters the combustion space proper and it-is obvious that the air which entersthe fuel stream and is drawn up into the mixing chamber. with the fuel is, together withthefuel, superheated to a high degree before it is discharged from the V mixing chamber into the combustion space. It is likewise apparent that the wall ofthe fur nace orfire pot is rapidly heated to-a high degree at the combustion zone and that. the eficiency of my combined burner and heater is very high. Q 1
