ANNULAR BURNER AND SURROUNDING BAFFLE RING Filed Dec. 29, 1945 INVENTOR. WALTER 14 TAYL o2 I' L JIF ATTORNEY Patented July 3, 1951 ANNULAR BURNER AND SURROUNDING BAFFLE RING Walter W. Taylor, Oakland, Calif., assignor to Malsbary Manufacturing Company, Oakland, Calif a corporation of California Application December 29, 1945, Serial No. 637,892

1 Claim.

The present invention relates to improvements in burners and has particular reference to burners using natural gas, butane, propane or the like.

My burner is particularly intended to produce intense, concentrated heat over a small area where it is used for heating water in a superimposed coil,' but also adapts itself readily to use outdoors, as in orchards for frost prevention.

The principal object of the invention is to provide a burner in which complete combustion of gases is insured due to the fact that air is admitted into the gas in two different stages, just as the gas issues from the burner jet, and again after the combustion is partly completed.

It is further proposed to arrange the jets in the burner in such a manner that the gas is discharged in a lateral direction so as to be fully exposed to the air rising through and around the burner.

It is a further object of my invention to provide means whereby the burning jets of gas, after travelling a short distance, are broken by striking an abutment which changes the direction of the burning gas and allows a second supply of air to mix into the burning gas for completing the combustion.

And finally, it is further proposed to arrange the burner and the abutment in such a manner that upon striking the abutment and receiving the second supply of air, the burning gas rises from the abutment in substantially solid annular formation, while additional means are provided for injecting a flame on the inside of said formation.

Further objects and advantages of my invention will be presented as the specification proceeds, and the novel features of my burner will be fully defined in the claim attached hereto.

The preferred form of my invention is illustrated in the accompanying drawing, forming part of this application, in which:

Figure 1 shows a top plan view. of my burner, taken by itself;

Figure 2, a vertical 22 of Figure 1; and

Figure 3, an elevation of my burner as applied to a coil heater, portions of the latter being broken away to disclose the interior.

While I have shown only the preferred form of my invention, I wish to have it understood that various changes or modification may be made within the scope of the claims hereto attached, without departing from the spirit of the invention.

section taken along line Referring to the drawing in detatil, my invention comprises in its principal features, a ringshaped burner l and a ring 2 of sheet material, preferably stainless steel, surrounding the same. The burner is preferably tubular in cross-section and may be supported at the end of a gas pipe indicated at 3.

The gas pipe 3 carries a frame comprising three

standards

4, 5 and 6, the first one of which is channel-shaped for strength and is mounted upon the gas pipe, while the other two may be in the shape of angles.

The three standards are interconnected at the bottom by means of a slightly dished disc 1 and carry the ring 2 in concentric relation to the burner.

The burner has a plurality of jets or orifices 8 arranged to discharge the gas outwardly, at an angle of substantially 45 and has also a number of jets 9 arranged to discharge gas inwardly at approximately the same angle.

The burner is mounted with free access of air from the bottom so that rising air may freely pass through and around the burner for mixing with the jets of gas issuing from the burner at the angle indicated. The fact that the gas issues from the burner in a lateral direction, both inwardly and outwardly, exposes the jets of gas to the fiow of the rising air for thoroughly mixing the air with the gas.

The ring 2 is here shown as of approximately twice the size in diameter, as compared with the burner, but its dimensions and location may best be determined by the function expected of it. The upper edge of the ring should lie in the path of the gas jets, so as to cause the latter to strike the upper edge of the ring, to be broken up thereby and to be deflected in an upward direction.

The ring should be considerably larger than the burner so as to expose a substantial part of the jets to the rising air before they reach the ring. On the other hand, the ring should not be so large that the lateral velocity of gas jets is spent before they reach the ring.

The height of the upper edge of the ring should be such that the jets strike the ring at the upper edge so as to allow air from the outside of the ring to freely mix with the gas while it is broken up and diverted into an upright direction.

This secondary supply of air insures complete combustion, and the combined result of the three factors involved, the breaking up of the gas jets, the change in direction and the admixture of a new supply of air, is that the burning gas rises frost, the ring might.

of the burner, as shown in the drawing, so as to furnish protection against wind and side draft.

Figure 3 shows the burner as applied to a water heater comprising a vertical cylindrical housing l0 having a coil I l therein, the water entering at l2 and leaving at I3. The burner is mounted underneath the coil, as shown, preferably by supporting the pipe 3 on a bracket l4 depending from the housing.

In operation, as the jets of gas are discharged laterally in an angular direction, the air flows through and around the burner ring to mix with the gas and to support combustion.

As the jets of the burning mixture strike the upper wall of the outer ring, they are broken up and directed upwardly, while at the same time a new supply of air coming from the outside of the ring mixes into the flame to insure complete combustion of the'gas contained therein.

The flame then rises in a substantially solid wall from the upper edge of the ring, during which time the inner jets, which converge toward the center and receive their main air supply from the inside of the burner ring, provide an additional flame inside of said wall.

I claim:

In a device of the character described, a gas pipe having a horizontally disposed, ring-shaped burner at the end thereof, a standard supported by the pipe to extend above and below the same, a ring supported by the upper end of the standard concentrically with the burner and dimensioned to form a relatively wide annular passage therewith and having an upper edge rising above the elevation of the burner, the burner havin directional orifices pointing toward said upper edge, and a horizontally arranged disc carried by thelower end of the standard to extend below the burner and the ring and in vertically spaced relation thereto.
