HYDROCARBON-BURNER.

SPECIFICATION forming part of Letters Patent No. 615,211, dated November 29, 1898.

Application filed May 23, 1398. Serial No. 681,528. (No model.)

To all 1071,0111, it may concern.-

Be it known that I, JAMES P. CALL, a citizen of the United States, residing at Redondo, in the county of Los Angeles, State of California, have invented a new and useful Improvementin Hyd rocarbon-Burners, of which the following is a specification.

My invention relates to improvements in hydrocarbon-burners in which hydrocarbon fluid in the presence of steam is injected into the furnace to form a fuel; and it consists in the novel method in which the steam and fluid are injected into the furnace and in the novel manner in which the burner is constructed.

The objects of my invention are to provide a burner of simple construction which will feed the oil into the furnace immediately below the steam-outlet and to utilize the suction created by the discharge of the steam to draw the oil up and out of the oil-discharge port and at the same time to provide a burner in which the different parts may be readily cleaned without removing the burner from the furnace. I accomplish these objects by the mechanism described herein and illustrated in the accompanying drawings, in which- Figure 1 is a side view of my burner. Fig. 2 is a top view of the oil-discharge chamber.

A is the steam-pipe connected to a boiler and having mounted thereon the usual steamcontrollingvalves. (Notshown.) Thispipe is located above the oil-pipe B and has cut in the end which projects into the furnace the horizontal steam-discharge slot I. Attached to the oil-pipe B is the oil-discharge chamber D. Forming a part of the top of this chamber is a plate D, adj nstably attached by means of the bolts E, its front end conforming to the shape of the chamber D, which at this point is circular. The opening between the end of the plate D and the casing of the chamber D forms the oil-outlet F. The size of this outlet can be regulated by means of the bolts E. This is rendered necessary on account of the different consistency of diffen ent oils. The oil and steam pipes are connected by the pipe H, having cut-0E valve L, thereby affording means to pass steam through the oil-pipe and oil-discharge chamber to clean the same. The brace M connects the ends of the oil and steam pipes.

The plugs K, which are screwed into the fittings on both the oil and steam pipes, enable the operator by unscrewing them to remove obstructions that may lodge in the nozzles without removing the burner from the furnace. The steam-outlet I is semicircular in longitudinal section and conforms in shape to the oil-outlet F, being disposed above and slightly in the rear of the oil-outlet.

I have found by careful experiments ex: tending over many months that burners of this class are very sensitive and that slight changes in relation to size and location of parts will almost destroy the efficiency of a burner. I have used a burner of a size adapted for use in a furnace having a capacity for steam production forengines of from thirty to one hundred nominal horse power and which has given satisfaction. It is constructed from one-fourth-inch pipe. The steamnozzle A has a discharge-slotone-sixteenth of an inch in width. The oildischarge chamber is one inch wide, with walls one-eighth of an inch thick. The discharge opening F when at its minimum capacity, as shown in Fig. 2, is one-eighth of an inch in width. The dotted lines, Fig. 2, show how the opening maybe enlarged by the adjustment of the plate D. The top of the oil-discharge chamber D is parallel with and one-fourth of an inch below the slot I, which is immediately above and slightly in the rear of the oil-discharge outlet. When different-sized burners are constructed, these proportions should be observed.

In all burners with which I am acquainted in which the oil and steam are injected into the furnace separately the oil is fed into the furnace above the steam. In my burner it is fed below. -I find by experiment that this produces better results, as but little, if any, residuum is deposited in the oil-discharge outlet. My burner is operated in the usual manner.

Having thus described my invention, what I claim as new is- 1. A hydrocarbon-burner composed of a steam-pipe, having a nozzle with a horizontal slot, adapted to discharge the steam horizontally over and across the oil-discharge outlet, and an oil-pipe having an oil-chamber located under the nozzle of the steam-pipe, having an adjustable discharge-opening; the oil-chamber having, at its minimum capacity, a semicircular opening adapted to discharge the oil upward immediately in front of and just below the steam-nozzle, substantially as shown and described.

2. The herein described hydrocarbonburner, comprising the steam-supply pipe, A, and oil-supply pipe, B, the steam-pipe, A, having nozzle, A, with steam-discharge port, I, and the oil-supply pipe, B, with the oil-discharge chamber, D, the oil-discharge chamber, D, having adjustable plate, D, mounted in the top of said chamber, and the adjustable plate, D, substantially as shown and described.

3. A hydrocarbon-burner for furnaces having a semicircular steam-nozzle, I, at the end of the steam-supply pipe, A, and an oil-discharge chamber, D, at the end of the oil-supply pipe, B, the chamber, D, having the inner side of the front face semicircular, and the adjustable plate, D semicircular on its front end, to conform in shape with the inner side of the front face of the chamber, the intermediate space forming the oil-discharge port, F, located substantially as shown and described.

4-. In a hydrocarbon-burner, provided with a steam-feed pipe, A, projecting horizontally into the furnace, and terminating with a semicircular steam-outlet, I, and an oil-feed pipe,

B, disposed immediately below the pipe, A, and terminating in an oil-discharge chamber, D, the oil-discharge chamber, D, semicircular on the inner side of its front face, to conform in shape with the front end of the adjustable plate, D, and the adjustable plate, D, being semicircular at its front end and secured in position by nuts, E, substantially as shown and described.

5. In a l1ydrocarbon-burner, having oil and steam supply pipes with their regulatingvalves, the discharge-chamber, D, having adjustable plate, D, the front end of which is semicircular, disposed immediately below and slightly in advance of the steam-discharge outlet, and so arranged that the oil-discharge outlet afforded by the semicircular opening intermediate the front end of plate, D, and that part of chamber, D, immediately in front thereof will be below and slightlyin advance of the steam-outlet and steam-pipe A, having nozzle A with steam-discharge port I, Whereby steam ejected from the outlet, I, will pass over and mingle withoil ejected from the oiloutlet, F, substantially as shown and described herein.

Signed by me, at Los Angeles, California, this 6th day of May, 1898.
