3. HURLBUT ET AL 293729953 BURNER Filed Dec. 27, 1940 Patented Apr. 3,. 1945 BURNER James H. Hurlbut, Huntington Park, Thomas J. Davidson, Montebello, and Roy N. Bowman, Southgate, Calif., assignors to Rheem Manufacturing Co., Richmond, Calif., acorporation of California Application December 27, 1940, Serial'No. 371,900
3 Claims. (Cl. 158-116) Our invention relates to hydro-carbon burners, particularly adapted for water heaters, although not limited to such use.
One of the principal objects of this invention is to provide a burner of this class comprising separate burner rings which, when placed toget-her, form ports at their outer portions for conducting the fuel gas, and in which the rings are forced together at theirouter port-forming portions by clamping means at the radially inner portions.
Another important object of this invention is to provide a burner of this class in which a duplicate of one of the members is spaced above the burner to provide a baille for directing secondary -air against the flame issuing from the ports of the burner.
An important object also of this invention is to provide a burner of this class having baille means at opposite sides of the flame issuing from the ports of the burner for directing secondary air to the flame above the base thereof to facilitate combustion, and also to determine the direction of the flame in order to deflect the flame from portions of the burner.
It is also an object of this invention to provide a lower or outer baille which is directed outwardly away from the llame for deecting the secondary air away from the base of the flame but so constructed as to allow such air to rise toward the outer or upper portion thereof.
A further important object of this invention is to provide a burner of this class which is particularly simple and economical of construction, durable, and efficient.
With these and other objects in view, as will appear hereinafter, lwe have devised a hydrocarbon burner having certain novel features of construction, combination` and arrangement of broken away and in section to facilitate the il lustration;
Fig. 2 is an enlarged fragmentary plan view thereof, taken at 2-2 of Fig. 1;
Fig. 3 is an enlarged sectional elevation thereof, taken through 33 of Fig. 2; and,
Fig. 4 is an enlarged, fragmentary section taken on line 4-4 of Fig. 3.
On the opposite or -outer end of the mixing tube is carried the burner proper which consists essentially of the burner elements II and I2. The opposite or outer end of the opening of the mixing tube is directed upwardly for directing the fuel mixture into these burner elements II and I2.
The burner element II, which will be referred lto as a burner ring, is provided at its periphery with a ledge IIa which is inwardly bevelled. From this ledge the ring is pressed downwardly to form an annular channel II". At one side of the channel is an enlarged opening IIc provided with a downwardly extending flange IId which is preferably welded to the outer end of the mixing tube over the outer end of the opening therein. The central portion of the burner ring is open, asindicated by IIE, to permit the passage of secondary air for the flame.
The burner element I2 is a port-forming disc. The peripheral portion of this disc is inclined upwardly. to conform to the inclination of the ledge IIa, and is provided with a multiplicity of corrugations I2a which are directed upwardly and outwardly. The outer portions of the corrugations rest upon the ledge IIa and this corrugated portion forms with the ledge a series of out-` wardly and upwardly directed ports A for the escape of fuel gas. The central portion of the disc I2 is also open, and the portion adjacent the opening is bent downwardly and around the corresponding inner edge of the burner ring II. These rings` .are thus rigidly secured together. When securing the two rings together, both of the rings are sprung or distorted axially, resiliently forcing the peripheral portions of the rings together. J
Positioned axially above the burner portion, comprising the rings II and I2, is` a baille I3. This baille, for economy of construction, is made identical with the disc I2 prior to the downward bending of the inner portion.
The baille I3 is supported in spaced relation to the port-forming disc I2 by means of brackets I4 secured to the lower side of the bale. Preferably three of such brackets are provided. The brackets I4 are made of metal straps extending The peripheral portion of the burner ring II has a flange IIx which extends beyond the peripheral portion of the port-forming disc, that is, beyond the base of the flame issuing from the ports. This flange III is bent radially outwardly from the ports.
asvaoss' Air for the initial combustion 'of the gas in the v burner is supplied through the mixing tube, but secondary air is supplied to the outer and inner sides of the flame, issuing from the ports A, around the edge` of the baille I If and between the disc I2 and the baille I3. Air passes upwardly along the outer side of the burner ring II and is then deflected outwardly. As this air rises it, impinges against the flame upwardly or outwardly from the base, tending to bend the ame upwardly. Both sources of secondary air determine the position of the iiame, asindicated in Fig. 1, so that the upper or hot portion of the ame is deiiected` from metallic portions of the burner.
Though we have shown and described a particular construction, combination, and arrangement of parts and portions of our burner, we do not wish to be limited to the same, but desire to include in the scope of our invention the construction, combination, and arrangement substantially as set forth in the appended claims.
We claim:
1. In a burner of the class described, a pair of burner rings in the form of discs, the radially inner portions of the discs being positioned to` gether flatwise, means for clamping the radially inner edge portions of said rings together. the peripheral portion of one of the rings, at the side adjacent the other ring, having an outwardly and upwardly inclined conical ledge, and the peripheral portion of the adiacent side of said other ring having circumferentlally spaced radial portforming portions, the port-forming portions being resiliently clamped against said ledge by the inherent spring ot the metal caused by clamping o1' the radially inner edge portions ot said rings together said rings being spaced apart between theirinner edge portions and the port forming portions whereby a'ruel distributing means is provided for ports formed by the'port forming portions and ledge. I
2. In a burner of the,class described, a pair of burner rings in the form of discs, the radially inner portions of-the discs being positioned together atwise, the radially inner edge portion o! one of the' discs being bent over the corresponding inner edge of the other, the peripheral portion of one of the rings, at the side adjacent to the other ring, having an outwardly and upwardlyinclined conical ledge, and the peripheral portion of the adjacent side of said other ring having circumferentially spaced, radial port-f forming portions, the port-forming portions being resiliently clamped against said ledge by the inherent Aspring of the metal caused by clamping of the radially inner edge` portions of said rings together said rings being spaced apart between portions whereby a fuel distributing means is provided for ports formed by the port forming portions and ledge.
3. In a burner of the class described, a pair of burner rings in the form of discs, the radially inner portions of the disks being positioned together flatwise, means for clamping the radially inner edge portion of said rings together, tbe peripheral portion of one of the rings, at the side adjacent to the other ring, having an outwardly and upwardly inclined conical ledge, and the peripheral portion of the adjacent side of said other ring having circumferentially spaced radial port-forming portions, the port-forming portions being resiliently clamped against said ledge by the inherent spring of the metal caused by clamping of the radially inner edge portion of said rings together, there being formed radiatingv ports by the adjacent peripheral portions of the rings, said discs diverging` gradually from their radially inner secured edge portions, the radially outer portions between the discs having a deep channel with which the inner ends of the ports communicate.
