PATENT OFFICE 13 Claims.

This invention relates to improvements in gas burners and more particularly, to burners of the vertically fired type employed for boilers or the like.

Some of the objects of the invention are to provide a short flame vertically fired gas burner that may be easily installed or removed from the flre box of a furnace; which will have a wide range of capacity and high efliciency; and which will also require only a low first cost.

Another object is to furnish a burner having an improved mixing head which although of elongated form will evenly or uniformly discharge the gas throughout the length of the head.

A further object is to supply an elongated mixing head to create a constant velocity of the gas at all discharge points and thus provide an even distribution of the flame issuing from the burner.

A still further object is to provide improved means for supplying secondary air to be mixed with the gas discharged from adjacent burners.

With the foregoing objects outlined and with other objects in view which will appear as the descriptionproceeds, the invention consists in the novel features hereinafter described, illustrated in the accompanying drawings, and more particularly pointed out in the appended claims.

In the drawings:

Fig. 1 is a side elevation partly in vertical section of a portion of a furnace provided with plurality of my improved burners.

Fig. 2 is a vertical sectional view taken on the line 22 of Fig. 1 and showinga pair of the burners in transversevertical section.

Fig. 3 is a view similar to Fig. 2 but showing modification. w 1

Fig. 4 is an enlarged bottom plan view of a removable plate which forms a cover for the burner head.

Fig. 5 is a side elevation of the same.

Figs. 6 and 7 are transverse sectional views of the removable plate taken respectively on the lines 6-6 and 1-1 of Fig. 5.

Referring to Figs. 1 and 2 of the drawings, it is to be understood that my improved burners are to be arranged in any suitable furnace setting to which a gaseous fuel is supplied by pipes 8 located in the ash pit (not shown) of the furnace.

At an elevation where the grate of the furnace is usually located, I arrange spaced plates 9 of "metal or any other suitable material and such plates form rigid horizontal supports. Each plate forms rings I through which the down tube ll of a burner may be inserted until its lower 55 end I2 is brought to rest on one of the'pipes I,

which pipe may serve as a support for the burner. Q

The lower end of each tube is provided with a collar 13 which surrounds a nozzle 14 through which the fuel is discharged from pipe 8 into the tube ll. Said tube forms a Venturi throat Hi, the restricted portion of which is arranged direct- 1y above the nozzle l4. Slots I6 at opposite sides of the tube II are preferably positioned below the upper end of the nozzle l4 and supply primary air to the burner.

Tube ll terminates at its upper end in an enlarged flared head I! forming an elongated substantially V-shaped groove or channel l8 that, communicates with the interior of the tube ll. Such channel is partially formed by upwardly diverging walls I! arranged at opposite sides of the head 11.

A removable plate 20 forming an important feature of the invention cooperates with the head I! to provide a mixing head. Such plate, as best shown in Figs. 4 to 7 inclusive, consists of a flat medial portion 2| from which projects upwardly diverging wings 22 that are positioned parallel to the wall l9. Each wing is provided with a series of spaced depending lugs 23 which rest on the walls l9 and space the wings 22 from these walls so as to provide each side 'of the burner head with a series of outlets or discharge passageways 24 (Fig. 2).

The inner end of each of the lugs is Preferably of V-shape, as shown at 25, to divide the fuel mixture discharged from the head into a number of streams.

Each plate is provided at its ends with substantially V-shaped depending flanges 25a to rest on the ends of the head I! and prevent the mixture from discharging through the ends of the head.

Each plate has a pair of parallel depending flanges 26 extending throughout the length thereof into the channel I8 and each flange is notched as shown at 21, 26, 29, the notches increasing in width toward the ends of the plate. Consequently, the mixture flowing from the Venturi I In order. to create a constant velocity of the gas at all points and thus provide an evendistribution of the flame coming out of the passageways 24, the varying spaces or notches function to effect uniform distribution. The spaces 21 being I smaller than the spaces 28 and 29, decrease velocity at the medial portion of the head while the adjacent sides of two burners will come together Y along a central line between two of the burners and there the mixture can be ignited by means -of a pilot burner 30. The latter preferably extends through metal plates II which are removably supported by ledges 32 at opposite sides of the plates 9, and the plates II are preferably provided with slots 33 to permit the upward flow of secondary air. Other openings or ports II for secondary air are formed by the rings l0.

Instead ofmaking'the plates 3! flat (Fig. 2) they may be of inverted V-shape, as shown at 3iain1'lg.3. I

From the foregoing it will be understood that the substantially V-shaped throats of the burner heads are to provide a flame at a -central location between two burners, and this flame will combine with the secondary air passing through this V-shape construction to cause the mixture out 'of the sides of the burners to be combined with secondary air, especially upon the burning of mixed gases in order to increase the combustion in a short flame, since an even combustion is practically impossible witha strictly upright flame discharging from a Venturi tube.

Many modifications of the invention will be parting therefrom or from the scope f the claims, and since the foregoing disclosure has been given byway of example for clearness and understanding, no unn limitations should be understood, and the appended claims should 5 be'construed as broadly as-the state of the art permits.
