BURNER.
Specification of Letters Patent.
Patented Feb. 11, 1908.
Application filed June 4, 1907. fierial No; 377,272.
T all whom it may concern:
Be it known that we, LEVI D. YORK and GEORGE YOUNGMAN, citizens of the United economize fuel and give increased efficiency in operation.
The burner is adapted for use with gaseous or pulverized solid fuel, as will later appeari The characteristics and advantages of our invention are more fully set forth in connection with the detailed description of the accompanying drawing in which the invention is embodied and in which- Figure 1 is a longitudinal section through a burner embodying our invention; and Fig. 2, a left end view of same.
Reference numeral 1 is a, thimble to be inserted in the opening of the furnace or fire box and form a liner therefor; 2, a flange thereon; 3, the hollow body of the burner;
4, a flared conical inner portion of the body;
5, a flange thereon by which the body is riveted as at 6 to the thimble; 7, a plurality of secondary air supply openings in the flared portion 4 of the body; 8, a ring mounted on the body and revoluble in relation thereto; 9, a plurality of holes in ring 8 corresponding to holes 7 in the body, the holes 7 and 9 being brought more or less into register by revolving ring 8 and the quantity of air admitted through these openings thereby regulated; 10, a cone or flame spreader within the body, conveniently made integral therewith and supported therein by arms 11. This cone is preferably made with an increasing flare toward its inner end as shown at 12, but the exact proportions and curvature to the flare of the cone may be varied to different conditions; 13, a nozzle casting secured in the outer end of the body at 14; 15, the nozzle proper supported centrally in casting 13 by arms 16; 17, a screw-thread in the nozzle by which a fuel-supply pipe may be secured to the nozzle; and 18, the jet end of the nozzle adjacent to the point of cone 10.
In operation gas, or pulverized fuel, such as coal dust, carried by an air current by either forced or natural draft, enters the nozzle 15 from the supply pipe (not shown) and issues from the jet 18, where it is ignited in any suitable manner. The flame impinges on the outer surface of cone 10 and passes back into the thimble around the edges of flared portion 12 of the cone which serves to divert the flame sheet so that it practically fills the thimble. Suction created by the flame jet draws air in considerable quantities through openings formed around the nozzle between arms 16 sufficient to supply the necessary elements for combustion to the fuel. As the flame leaves the rear end of the cone and passes into the thimble, additional air to further assist the process of combustion is drawn through apertures 7 and 9, and the amount of this secondary air supply is regulated to suit the conditions by rotating collar 8 and so varying the size of the openings. When the apparatus has been in operation for a short time the natural draft created in the furnace of fire box creates further suction and assists in the proper supply of air to the burner.
The particular construction and arrangement of parts shown and described are such as to insure thorough combustion of fuel, supply an ample flame to the furnace to which the burner is applied, and give highly efficient results.
We do not limit ourselves to details, but
contemplate any changes within the spirit of our invention.
, We claim:
1. In a burner, the combination of a body having a cylindrical portion and a flared rear portion, a spider removably secured in the front end of the body, a nozzle carried by the spider and co-axial with the body, a conical flame spreader supported by a spider centrally within the tubular portion of the body rearwardly flared flame spreader supported flared portion of the body for regulating the by a spider centrally Within the tubular porauXilary-air admission. tion of the body With its apex approximately L YORK in the plane of the mouth of the nozzle, aux- 5 iliary air inlets in the flared portion of the GEORGE ,YOUNGMAN' body, introducing air directly into the body Witnesses: back of the rear end of the spreader, and a H. H. HIGGINS, revoluble apertured ring located against the ED. W. FEAZEL.
