To all whom it may concern.' i
Be it known that I, JOSEPH C. GEFRING, citizen of the United States, residing at Pittsburgh, in they county of Alleghen u andv State of Pennsylvania, have invente certain-new and useful Improvements in Gas- Burners, of which the following is a specii ication.
This invention relates to gas burners and comprehendsthe production of a gas burner wherein improved means is .provided for the mixing and combustion of the-heating One ofthe objects of, the invention is .the construction of a sim le as burnerl having a gas superheating c am er in connection with an air and gas mixin chamber so that the gas to be consume 4 superheated and then-thoroughly mixed wlth the-air before being converted into heat.
Another object vof the invention .is the construction of a gas burner having a gas superheating chamber .arranged around a,l gas supply pipe and connected to a miningy chamber in such amanner that 4gas entering the superheating chamber from the supply pipe will be superheated so as to enter the 1 mixing chamber under pressure and in such a way as to intimately mix with air dra-wn in by said gas escaping from the super. `heating chamber.
. With the above and other objects in view vthe invention consists in certain combinations, constructions and a-rrangements-of parts, clearly described in the followlng accompanying drawings, inwhich,
Figure 1 is a detail vertical sectional view showing one part of the improved burner, Fig. 2 is a horizontal sectional view showing the construction of both halves of the burner, each half being like the other, Fig.
3 is a horizontal sectional View of a singlel illustrating the preferred form of themvention l denotes a gas burner, which is,
will rst be provided with mediately disposed discharge;
tubes 4 which project outwardly, said tubes bem formed lntegral with said burner;
T e horizontal partition 2 is connected with a vertical partition 5, the upper end of which projects above the horizontal partitical'partition 8, which is ofconsideraole less length than the partition or wall 5 yto which is screw threaded the gas supply- `and is spaced inwardly thereof by said art'ition 8 termipipe 10. The outer or intermediate vertif cal partition 5 is provided with minor discharge tubes or hollow-outlet members 11,v
the bores of which are ared outwardly, and
'which are disposed within the plane of the discharge tubes, 4` but above the lower sides of .said tubes or hollow members. It will` thus be 'seen that a fluid expansion chamber is formed which is substantially' formed withl a central inverted U-shaped i partition, which extends to a point above said discharge tubes or outlet members 11.
The mixing chamber is surrounded by a wall or. shell 12, which is -spaced apart from the intermediate wall 5 so as to -leave a channel .13 through which air'can ow into the mixing chamber 3 and escape with the gas issuing from the minor discharge tubes 11, the bores of which are flared outwardly, and which are disposed within the plane of the discharge tubes 4, but above the lower sides of said tubes.`
From the above arrangement it is to be noted that the Vdischarge conduits 4 are integrally formed vupon both the expansion vchamber 14 andV the shell 12, and that the outlet members 11 .are integrally formed upon. said chamber at central and diametrically-opposite points and project concentrically Aor between the walls of said conduits,
but terminate centrally of theair, channel 13, so that ythe escaping products of combustion may intimately mix withthe inrushihg air at the corner. between the channel 13 and conduits 4.-
When the burner has been supplied with gas and the same ignited the top 6 and the walls ofthe discharge tubes will be heated to a high temperature. The vertical wall andthe top 6 and the bottom spacing partition 7, with the inner partition 8 inclose a space whichconstitutes a superheating chamber 14. As the gas leaves the top of the supply pipe 10 it will enter the superheating chamberV 14, striking against the heated top 6, and escape under pressure through the minor or gas discharge tubes 11 into the upper part of the mixing chamber 3, and thence directly out through the gas and air discharge tubes 4. As the gas leaves the gas discharge tubes 11 it will be spread outwardly so as to enter the chamber 3 Vin a spray and intimately mix with the air, which will be drawn by the outflowin up through the entrance 13 into the mlxing chamber 3 and out with the gas through the discharge pipes .4, which constitutel the burner tubes properj It will be noted that the gas discharge tubes do not project across the entrance 13 but only half way across and that they are adapted to spray gas into the chamber 3 and the discharge tubes 4 so that the gas will evenly enter said tubes, in-
stead of striking against one side or wall of same. iA part of the gas striking the top wall 6 will be deliected downward so as to enter the lower part of the chamber 14,
thus being hea-ted by the lower part of the vertical walls of this chamber. The entrance 13 for the inilowing' air surrounds '40 the entire wall or partition 5 so that an abundance of air can enter the chamber 3.
Should it be desired to connect two supply pipes with the superheating chambers a dividing wall or partition 15 is arranged between the supply pipes, as shown in Fig. 2. In Figs. 3 and 4 is illustrated a modified form of the improved burner, wherein 16 denotes an annular outer wall, which is provided with burner or discharge tubes 17,
ve being shown.` Within the outer wall\ 16 a wall 18 is disposed, being provided with gas discharge tubes 19 adapted to discharge gasinto the tubes 17 andthe space between the-partitions or walls 16 and 18. Within the wall 18 a partition or wall 20 .is disposed, being spaced apart from the wall 18 by a horizontal partition 21, in a manner like that of the construction Shown in Figs. 1
' and 2. The partition 18 projects above the plied with gas through the su ly connected' with said chamber.
top of the outer wall or partition 16 to inclose ja superheating chamber, like that shown in Fig.- 1, and thischamber is supl ipe 22 is orm of -to the tubes 24 and the wall 25 by a horizontal partition or wall 27. The structure 26 is divided by a central partition 28 into two compartments and supply pipes 29 are connected to each of these compartments or chambers. From the sides of the box like structure 26 gas discharge tubes 30 project so as to spray gas into the chamber 25 and the tubes 24.
As gas leaves the upper ends of the pipes 29, which are located below the tubes 30 it will lstrike against the upper part or top of the chamber formed by the structure 26, be i deiected downwardly at a higher temperature, so as to strike in part the bottom of the structure 26, and then escape through the tube 30, into the air -mixing chamber 25 and thence out throu h the tubes 24.
The outlet or ischarge tubes 4 are referably deflected at an upward angle o thev wall 12, so that thesames esca ing from saidtubes will be inclined upwar ly of said wall 12. By this arrangement the ow of air through the mouth 13 will be stimulated, asa greater draft is thereby developed.
Having described my invention, I claim and desire to secure ,by Letters Patent 1. A burner comprising a relatively-large f iuid expansion chamber, a shell spaced around said chamber to form an air channel therewith, hollow members communicating: with said chamber, conduits formed integrally upon said chamber and shell to dischar e the fluid escaping from said hollow mem ers, said hollow members being disposed concentrically of said conduits and terminating short of the mouth thereof, and in) iuid inlet member connected to said cham- 2. In a burner comprising a relativelylarge duid-expansion chamber and an inl verted U-shaped partition .disposed in and spaced from the walls of said chamber, the combination of a shell spaced around said chamber to form an air-conduit therewith, hollow members communicating` with said chamber at .points below the top of' said U- shaped partltion, conduits formed integrally upon said chamber and shell to discharge ,the Huid escaping from saidL hollow members, said hollow members disposed substantially coneentrically of said last-named conduits and being located vbetween said chamber and shell, and a fluid inlet member yconnected' to the base of said U-'shaped partition.
3. A burner comprising a relatively-large fluid expansion chamber, an. vinverted U- shaped partition, disposed in and spaced from .the4 walls of said chamber, a shell spaced around said chamber to form an airchannel therewith, fluid' discharging con- 10 duits formed integrally upon ,said chamber and shell, hollow imembers in line with said vconduits and communicating with' said In testimony whereof I ailix my signa- 15 ture, in presence of two Witnesses.
