HARRY E. KERR, O]? CLEVELAND, OH IIO,.ASSIGNOR TO THECL EVELAND GAS BURNER & APPLIANCE COMPANY, OF CLEVELAND, OHIO, A CORPORATION OF OHIO.

GAS BURNER,

application filed September 9, 1926. Serial No. 134,390.

The present invention pertains to an improvement in gas burners of the general type shown and described in my Letters atent of the United States, dated Nov. 3,

1925, No. 1,560,248; Thus the improved burner embodies air and. gas delivery tubes corresponding to the tubes in the patented burner and arranged in reversely-inclined relation to bring separate streams of com- 1 bustible mixture into confluence and to generate a spreading column of flame apart from the mouth of each tube and the body of the burner. The present burner is distinguished however from the patented burner in that the burner body is particularly constructed to rovide a double row of delivery tubes at ditibrent elevations and projected toward each other at right angles to produce a sheet or column of flame in an oblique or slanting plane so that it may be directed against a vertical wall such as a fire pot wall in a boiler, furnace or other heating apparatus. In addition, the present burner considered as a whole comprises a lurality of sections or units, adapted to orm a large ringshaped burner when assembled, each section or unit having a'valved connection leading to a common source of gas supply, and each section or unit comprising two hollow circular segments concentrically arranged in different horizontal planes and 'havin co-operating pairs of tubes mounted radial y thereon.

In the accompanying drawings, Fig. l is a sectional view .of my im roved burner,

mounted within the fire pot o a circular furnace or boiler. Fig. 2 is a perspective view of the com lete burner connected to a gas supply headbr. Fig. 3 is a perspective view of one of the burner sections or units. Fig.

40 4 is a sectional view of one of the burner sections on the line of a pair of co-operating jets or delivery tubes.

In Fig. 1 I show my imprpved burner A mounted upon a grate 2 within a boiler or furnace 3, the showing of this articular boiler being merely an exemplificatlon of one adaptation of the burner to a known structure embodying a fire pot 4. To obtain the full benefit of, the heat generated by a gas burner in a boiler or-furnace of this general type 1t is especially desirable that the mixed gasesand flames from the burner be projected against the walls of the fire pot and that combustion takes place at the sides and over the entire area or full height thereof instead of being produced merely within the central area of the fire pot. The present burner is therefore particularly constructed to direct the combustible gases obliquely in an upward direction against the fire pot wall, and comprises a plural number of sections or units -a--, arranged within the fire pot closely adjacent the inner wall thereof. In the present instance three units --aare assembled together each being a segmental part of a double ring to permita circular gas burner to be formed thereb which is nearly as large at its greatest diameter as theinner circular wall of the fire pot, and this sectional construction is'desirable and of great advantage because it permits the burner to be assembled, section by section, within boilers having grates for burning hard fuel and in which the fire pot doors or entrances are of much smaller size than the fire chamber. Moreover, each unit -a is provided with a separate pipe connection 5 leading to a gas supply manifold or jieader 6, and separate valves, 7 are used to control the supply. and operation of each unit, so

that one or more or all the units may be operated at will or as heating conditions may require. The burner units -a-- are constructed alike. so that a description of one willsuffice for all. Thus, each unit comprises two hollow circular parts or segments 8 and 9, respectively, of different diameter, which segments are concentrically arranged and united together at their middle by a tubular connection 10. The opposite ends of each segmental part are closed'or plugged and the a corresponding ends are connected together by solid tie bars or webs 11. Outer segment Sis relatively longer than the inner segment 9, and these two segments, as united together by middle connection 10 and the end tie bars 11, form-a separable sector of a complete ring-shaped burner A which may be used ad- ,vantagcously within a round fire pot. (3on necting tube 10 and tie bars 11 extend inwardly and upwardly on slanting lines from outer segment 8 to support. inner segment 9 at a higher elevation than outer section, 8, The two concentric segments are thus supported parallel with each other but in dit' ferent horizontal planes, and supply pipe is connected to a boss 12 depending from one of the segments at about the middle thereof, and preferably from the inner segment 9 opposite the end of connecting tube for convenience in making header connections and to permit all of the connecting pipes -5 to pass through a single opening in the side wall of the furnace beneath the burner.

A series of small bosses 14 are formed oppositively at spaced intervals upon the segment 8 and 9, and a Series of gas deliveryjets, tubes or nozzles 15 are screwed into these bosses in open communication with the hollow gas-distributing passage 16 in each segment, the tubes being arranged in pairs and the tubes of each pair being projected toward each other at approximately right angles-so that two separate streams of gas will be discharged and brought together opposite and apart from the outer ends of-the tubes. Thus each tube hasa small gas orifice 17 in its base and one or more lateral air .intake openings 18 in its side closely adjacent said orifice, whereby a fine stream of'gas will be discharged into and through the tube and a predetermined amount of air will be'entrained and discharged with the gas. Under maximum operating pressures the two gas streams are brought into confluence anddeflected at a diverging angle to the axis of each tube and no combustion takes place at or in the zone of meeting of the, two gas streams except when the flow of gas is at reduced pressure. Normally a spreading column of flame is generated some distance apart from each pair of co-operating tubes and by mounting two sets of such co-operating tubes at right angles and also at different elevations,the combustible mixture and columns of flame will be projected obliquely or on upwardly slanting lines from each burner unit a and at spaced intervals around each unit against the lower part of the fire pot and upwardly along its sides with highly eflicient heating results. 'In a circular burner the separate sheets and columns of flame strike the fire pot radially thereof but in such close proximity that a continuous circular sheet of flame is produced within the fire pot. ,However, if only a sector of the fire pot is to be heated, the flow of gas to one or more units may be cut oflat the valves 7, and the volume or height of the flame at each unit may also be independently l controlled by such valves.

low gas distributing rings ofdifferent diarnif eters supported at diflerent elevations, a series of air and gas delivery tubes extending horizontally from the smaller and higher ring, and a series of air and gas delivery tubes extending vertically from the larger and 'lower ring, the said tubes being arranged oppositely in pairs to deliver separate streams of combustible .mixtures into confluence with oblique deflecting eflect.

A gas burner, comprising a hollow gas distributing body having air and gas delivery tubes extendin horizontally therefrom and air and gas delivery tubesextending vertically therefrom, the said horizontal and vertical tubes being arranged'in pairs to deliver separate streams of combustible mixtures into confluence and to s read the confluent mixtures in an oblique p ane.
