GAS BURNER.

Application filed June 28, 1928. Serial No. 288,896.

The invention relates to gas-burners of the type disclosed in the patent to Davis, No. 1,258,993, March 12, 1918, and the objects of the invention are to simplify and. cheapen the manufacture, to improve the operation and to facilitate the installing of such burners in the fire-boxes of conventional types of furnaces.

The invention will be described with reference to the illustrative embodiments of the invention shown in the accompanying drawings, in which:

Fig. 1 is a front elevation of a circular form of burner adapted for installation in a cir- 1 cular fire-box;

Fig.2 is a-horizontal section on the line 24-2 of Fig. 1';

Fig. 3 is a horizontal section, partially broken away, on the line 3-3 of Fig. 1;

Fig. 4 is a vertical section on the line 4-4 of Fig. 2;

. Fig. 5 is a front elevation of a rectangular burner for rectangular fire-boxes;

Fig. 6 is a plan of the burner shown in Fig. 25 5, and

Fig. 7 is a plan of the lower parts of the rectangular burner, the fire-brick and supporting plate being removed.

Referring to Figs. 1 to 4, a pair of mani- 39 fold pipes 1, 2, bent into half-circular form, are closed at their rear ends by caps 3, 4 and are provided with elbows 5, 6 at their forward ends. Short pipes 7, 8, each provided with a valve (9, 10) connect the manifold pipes 1, 2 with a header 11 which is in communication through valve 12 and pipe 13 with'a gas main (not shown).

The upper surfaces of the pipes 1, 2 are perforated by uniformly. spaced gas ports 14 (Figs. 3 and 4 anddirectly above'each port a Bunsen tube or jet 15 is mounted. The tubes 15 are vertically supported and horizontally spaced by metal bands 16,17, 18, 19 to which.

thetubes are welded. Metal straps 20 are clamped upon the manifold pipes 1, 2 and are secured at their ends by welding or riveting to the bands 16, 17 or 18, 19.

. A hollow T 21, constituting a pilot, has oppositely presented ports 22, 23, positioned so as to project a jet of gas tangentially across the upper ends of the front Bunsen tubes 15 of each semi-cylindrical tube section. The pilot is held in position by a strap 24, having one end bent around the pilotand the other end formed as an eye which slips over the faces.

outermost tube 15, on either side of the pilot,

and rests upon the bands 16, 17 The pilot 29, having flanges along their contactingedges, as shown at 31, Fig. 4.

Upon the disks 29, 30 rests a heat deflecting structure 32 of fire brick. It is referably made u of segments as shown an when assemble forms a cylindrical hollow shell with an outwardly flaring upper portion.

Referring now to the. rectangular type of burner illustrated in Figs. 5 to 7 and which is adapted for use in rectangular furnaces, it will be found that it is made up in eneral of parts corresponding to those hereto ore de scribed with reference to the circular type of burner. In the present instance, the manifold pipes comprise sections 33, 34, 35, 36, 37 38- disposed to form a rectangle and unitedat the corners of the rectangle by elbows 39.

' Since there are usually no water carrying elements adjacent the front face of rectangular furnaces, the burnertubes 15 are rovided along the sides and rear sections 0 the rectangle and the pipe sections 33 and 38 are therefore not perforated in their upper sur- A modified t e of pilot is desirable for this rectangular orm and, as shown in Fig. 7, it comprises pipe sections 40 and 41 having caps at their outer ends and a T 43 uniting the sections. The pipe sections 40 and 41 are perforated in their up 1' surfaces and burner tubes 15 are mounte above said perforations in the manner heretofore de scribed. In this instance the pilot is located in the rear of the furnace and overlaps several burner tubes of each of the end sections 35, 36. The pilot is connected to the gas supply by means of a pipe 44. This type of pilot places in proximity a plurality of pairs of pilot and working burners and this constitutes a safe-guard against the ilot going out or failing to ignite the main urners in the event that any of the burner tubes become inoperative by clo ging. The pilot also serves to close th6%) when the furnace is in operation. Gas is supplied to the pilot through the pipe 44.

The rectangular plate 45 is supported in urner ring at the rear relation.

qvertical series and definin substantially the same way aslhe circular disk 29, 30, heretofore described, but the clips 27 are disposed transversely and in parallel For greater rigidity. sleeves or channel bars 46 embrace the clips 27 and bridge the gaps between their ends.

The heat deflecting structure 47 of fire brickis similar in form and function to that heretofore described except that the sections are shaped so that they may be assembled in rectangular form and no sections of fire brick are provided for the front face of the furnace.'

In certain general respects, the construction. mode of assembling and operation of the burners herein described are the same as in the patent to Davis. No. 1,258,993. That is to say, the parts are formed in sections to adapt them for insertion through the fire door of a conventional furnace; and these sections and their auxiliary parts are adapted for easy assembly in the cramped quarters of the furnace. The heat deflecting structure (32 in Figs. 1 to 4, 47 in Figs. 5 to 7) is adapted to receive on its under surface and throw outwardly against the water carrying elements of the furnace, the flames rising from the burner tubes. The disk 29, 30 or the plate 45 serves to close thechimney formed by the fire brick and thus prevents a useless central draught which would tend to cool the chimney of the furnace and would reduce the draught around the burners.

As compared with the structure of the Davis patent this invention has advantageous features with res set to economy of manufacture and simp icity of. installation, without any loss of efiiciency. It will be observed that the fire brick has been materially sfhortened by cutting ofi the lower portions of the sections (shown in the Davis patent). The lower portions of the fire brick, as heretofore employed, served no useful purpose except that of support. According to the present invention the upper flaring portion is retained and fully performs its function as a heat deflecting element, since the region immediately above the burner tubes is the region of flame production. The disk 29, 30 or plate 45 serves, adequately for supporting the fire brick and at the same time closes off the disadvantageous central draught.

The shorter sections of fire brick are cheaper to manufacture and transport and easier to assemble in the furnace and the disk 29, 30 or plate 45is simpler and easier to assemble than the draught closing caps 5 and 6 shown in Fig. 1 ofthe Davis patent.
