z claims. (ci. 15a-10s) My improvement comprises a gas burner designed to meet the demand for a burner that will operate satisfactorily on either Y1000 B. t. u. natural gas or 1000 B. t. u. substitute gas without changing the adjustments on the burner; and further, a burner that will operate satisfactorily on the various low B. t. u'. manufactured gases.
In the design of a burner of this character a number of very definite problems arise,1 all-of which have been carefully considered and provided for in the present invention. A
Flashback must be overcome, this I have 'successfully accomplished by increasing the depth of the burning ports and by making them as narrow as shop practice would permit.A However, the deep narrow ports occasion considerableresistance to the flow of gas and it is thereforedesirable to make the sides of the ports smooth and free from rough projections. 'The narrow slotted ports, however, prevent the flame from traveling back down through them, which sets up a definite resistance to ashback.
The additional depth of the burning ports by increasing the area of metallic surface contacted by the air-gas mixture during its flow from the orifice to the burning edge, presented the possibility of heating the air gas mixture to such an extent that excessive pressures would result within the burner box. I overcome this tendency by cooling the burner head, this is done by bringing the secondary air for combustion up between the ports; this feature also furnishes a further advantage in that it gives a desirable distribution of such secondary air throughout the entire re.
To recapitulate; my improved gas burner includes an increased area of cooling surface on the burner head for the purpose of reducing the heating effect at these points; next, the increased depth of port overcomes flashback under variable conditions; and finally, I provide a wide and improved secondary air distribution to the' fire. These and other advantages will be apparent from a study of the drawing and as amplified through the description thereof which follows.
Fig. 1 is an end view of a single burner; it being understood my burner may be employed in multiple units if so desired. Fig. 2 is a side elevation of the burner shown in Fig. 1; a portion of the figure is broken away for purposes of description. Fig. 3 is a plan view of the burner. Fig. 4 is an end view of a modified form of the burner. Fig. 5 is aside elevation of the burner shown in Fig. 4. Fig. 6 is a top view of the elements seen in Fig. 2 with the burner port section disclosed in Fig. 3 removed from the assemblage. Similarly Fig. 7
shows a top view ofthe elements seen in Fig. 2 after removing the parts seen in Figs. 3 and 6. Similarly Fig. 8 shows atopl View of the base section seen in Figures 1 and 2 after removing the parts disclosed in Figures 3, 6, and 7. Fig. 9 represents a view in section as taken along the line'IX-IX in Fig. 2, and looking in the direction of the arrows. Fig.V 10 shows a fragmentary sectional view ofthe burner port as taken along the line X-X in Figure 2, and looking in the direction of the arrows. Fig. 1-1 is a sectional View as taken along the lline XI-XI in Fig. 1 and looking in the direction of the arrows. Fig. 12 is a sectional view as taken along the line XII--XII in Figure 4, and looking in the direction of the arrows. Figl13 is fa plan Y view of the burner base plate and Venturi -`tube integral therewith. VSimilar numerals of reference designate the same pa'yrt throughout the several figures of the drawing.-
Referrlng'fto the drawing, Yat Ill are the base casting walls, integral with an intermediate cast T-pipe fitting II provided with a jet I2. A rectangular shaped upper portion I3 is also integral with the side walls I0 and at the four corners thereof may be seen corner elements I4 and a raised triangular portion I 5. Upon the base seen in Fig. 8 and just described, I next assemble the element seen in Fig. 7 which has a base member I6 as a plate supported by the four corner elements I5. Integral with the member I6 is a Venturi tube I'I extending a little below the base I6 as at I'I and upwardly the height desired as seen in Figs. 9, 11, and 12. This Venturi tube may be surrounded by the wall element I8 as shown Figures 1, 2, and 11 in which case a slotted projection I9 would occur at the upper part of the end walls for purposes later explained. I next assemble an inner box-like element 20, open at its lower end and surrounding the Venturi tube I'I as disclosed in Figs. 6, 9, 11, and 12. The lower end of the element 20 is provided with a pair of centrally disposed extensions 2| and a pair of centrally disposed extensions 22, thus providing ports 23 and 24 at the lower side and end walls of the element through which the air-gas mixture, admitted through the jet I2, tube I'I and passage 25, will pass into the passage 26 intermediate the element 20 and the outer side walls I8. It will be noted that the upper end of the element 20 is closed by an inverted V-shaped roof portion as seen at 21.
The assemblage shown in Figures 1 and '7 just described is now ready to receive the burner element seen in Fig. 3. As will be noted in Figs. 4, 5, and 12, this element may have a depending Ydesired a gasket maybe employed as seen at 29 or at 29.
The burner seen in Fig. 3`and in the end views Figs. 1 and 4 is flat on the top edge at 3U, the sides extending downwardly for a distance-.as
seen at 3l from which they curveuinwardly and downwardly as at 32 to then flare outwardly along the line 33. The ends'of the burner are prefer- Y ably ofthe shape indicated at I8y. The `effect of the pitch given at 33 is shown in Figures 9, 10,` 11, and 12 as a top section arranged above the roof element 21 previously described, and for a continuation of the gas passage 26 as seen at 26:1: adrnitting the air gas mixture to the gas ports as later described. It will be noted in the several figures that the effect of the conventional Venturi tube seen at l1 is continued throughout the passage 25, the pasasge 26 and 26x, the -wall elements being so fashioned or cast as to give this characteristic. Deep narrow slots'34 provide the gas ports. A plurality of burner sections suchas 35 are seen in Figures 2, 3, 11, and 12 cast integral with the part 33 as disclosed in Fig.f11, in each Yof the sections 35 is disclosed the/deep narrow slotted orifices 34. Wide air passages for secondary air therefore occur from the side 36 to the side 3lY as clearly shown in Figs. 2 and 9. The effect of this secondary air upon theflame at the burner tip 30 is very pronounced both for cooling the members 35 as well as foi` improving the secondaryV air distribution.
My burner by eliminating flashback also eliminates noise and re hazards and other dangers. The invention in general is for similar purposes to that of my pending application for Gas burners, Serial No. 693,128.
Such modications may be employed as lie within the scope of the appended claims. Having fully described my invention, what I now claim as new and desire to secure by Letters Patent is; Y
V1. In a gas burner, a supporting member having a'gas service therein including a jet vertically disposed; a base member arranged upon the supporting member including a Venturi tube passing .through said plate and extending more above lthanbelow the plate in gas receiving relationship to'said'jet; a box-like enclosure surrounding said tube. Vand defining a passage therebetween, and having an inverted V-shaped top portion andgas v ports adjacent said plate, a flat top gas burner element arranged above the top portion of the box-like enclosure and provided with a correspondingrinverted -V-shaped under portionrto dene a selected passage communicating with said rst passage through said gas ports; an outer housing element extending from said plate an-d supporting said burner element; rectangular burner sections for the burner element spaced apart and in parallelism and having air passages therebetween from sideV to side of said burner element and downwardly extending alongthe sides thereof externally of said inverted V-shaped under portionsaid rectangular burner section havingla narrow vertical rectangular slot of considerable depth communicating with said selectedV passage. Y
2. A gas burner as defined in claim 1, characterized by the further fact that the circuitous passages leading fromthe Venturi tube to the burner have Venturi tube characteristics.
