T0 @ZZ whom it may concern.'

Be it known that I, HENRY Il. HYLAND, a citizen of the United States, residing at Pittsburg, in the coun ty of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Petroleuin-Burners and Steam-Gen craters; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

In usin petroleum and other hydrocarbons as a fuel for industrial purposes-si'lch as the generation of steam and the heating of furnaces of all kinds-in a cheap and economical manner it is necessary to take into consideration the facts that the fuel must be und er perfect control at all times, so that the operator can regulate the amount of heat supplied to the boiler or other furnace; that the liquid fuel must be transformed into a Vapor or gas before burning, as it will in that shape be so agitated or atomized that an approximately perfect combustion results; that the flow of oil to the agitator or vaporizer must be steady and equal, so that the heat generated will at no time vary unless desired by the operator; that the initial heatingl and steamgenerating must be derived from the same fuel as is used to keep up the continuous heat in the furnace, and that the parts to accomplish the last named result must have some function in the operation of the apparatus other than that of Vinitial heating and steam-generating, so that l there will be no superfluous or unnecessary parts in the device after the fire has been started.

The object of my invention is to embody in an apparatus elements and combinations of elements of such a character that all the conditions aforementioned will have a place in said apparatus and perform all the functions required thereof in a simple and economical manner and without danger to the workman and the surrounding property.

The invention therefore consists of constructions and combinations, all as will hereinafter be described and claimed, reference being had to the accompanying drawings, in which- Figure l represents a longitudinal section of a boiler with my apparatus attached thereto; Fig. 2, a perspective of the initial steamgenerator, which can also be used as a superheater; Fig. 3, a longitudinal section of the injector, and Fig. fl a transverse section through the oil' and mixing chamber of the injector.

In the drawings my apparatus is shown attached to a locomotive-furnace; but it is obvious that it can be applied to any other form of furnace, whether for generating steam or metallurgical purposes. The pipes are arranged diagrainmatically in Fig. 1 to show their connections; but in practice I shall arrange them in accordance with. the construction to which they are attached, an d will malte such chan as the nature of the constructions may require.

A represents the boiler 5 A', the lire-box; A2, the dome; A3, the cab having the floor A4, and A5 the initial heating and steam-generating device. The part A5 is arranged in the fireboX in any suitable manner, but preferably rests upon the dead-plates of the grates. It is formed of an outside coil of pipes, a, and a series of smaller pipes, a', arranged in any suitable manner, preferably in the manner shown-that is, a number of pipes arranged in horizontal rows and joined together at their ends by elbows and each alternate row having its pipe opposite the pipes of the other row, so that the heat will pass around all the pipes inclosed by the large pipes o, and each row is connected by one end to the row below it and by the other end to the row above it, and the lowermost row is connected to the lower coil of pipes, a, The top row is provided with a pipe, a2, which connects with a steam-drum, A6.

The lower coil of pipes, a, is connected by a pipe, o3, with a water-reservoir, A7, that receives its supply from any suitable source, and is shown in this instance connected by pipes a4 and a5 with the water-space of the boiler. Pipe a5 is provided with a cock, a6,

cutting off the supply when desired. Apipe, a7, leads from the drum A6 to an injector, B, located at the doorway of the fire-box, and which I will now describe.

B represents a casting having an annular chamber or oil-space, o, a nozzle, b', having a IOO passage, b2, opening at its rear end into a conoidal chamber, D?, into which projects a series of conoidal nozzles, h4, pointing to a common center, as shown in Fig. 4;, and separated at their extreme ends lf a sufficient distance to permit a blast of steam to pass opposite to apertures or openings in. the apices of said conoidal nozzles. c The rear ends of these co- .noidal nozzles open into the oil-chamber h, and are provided with valves b, cach having a needle, 127, for keeping the apertures of the nozzles clear, and a stem, bs, having a bandwheel, b, and screw-threads which engage with the screw-threads formed in the hollow plug bw. This plug has screw-threads on its outer surface to engage with the screw-threads of the openings U2 in the outer wall of the oil-chamber. A screw-cup, bw, is also screwed over the end of the plug, which extends outside of the oil-chamber to prevent seepage of the oil. In the rear end of the conoidal chamber b3 a spider, b1, is screwed. This spideris provided with a central openi ng, partly screwthreaded, for the steam-nozzles bl, which extend through said opening to a point near the ends b5 of the nozzle l1" and in the same plane as the common center to which they point. The rear part of the nozzle is partly inclosed by a perforated tube, hl, secured by one end in the casting B, and provided with a cap, t, screwed upon its rear end. rlhe rear .end of the steam-nozzle is provided with a tie-coupling, to one end of which is secured the pipe al, leading from the drum, and to the end a pipe, a8, leading to the steam-dome. This pipe is connected with pipe a by a pipe, a9, provided with a cock, am. rIhe pipes al and as are respectively provided with cooks a'12 and am. From pipe as a small pipe, a, leads to a steam-space, 618, formed by the cap 519, secured to the said nozzle. Oil is'supplied .to the chamber b3 by a pipe, C, connected ,with a suitable reservoir and havin gabranch pipe, C,which leads to the initial steam-heating device A.

The operation of the device is as follows: The cocks in pipe a4 are turned to admit water into the reservoir A7, and pass from there into the part A5. When a sufficient quantity has passed, the water is cut off, the cocks in the oil-pipes turned to admit oil into the branch C', and ignited to heat waterin pipes a. The steam generated in the latterpasses through pipe a2 to steam-drum A6. After a sufficient quantity of steam is supplied to drum A, the cock in pipe in al is turned to admit the steam into the injector B, and the cock in oil-pipe C is turned to admit oil into chamber b3, and passes through the nozzles h4 Ain line jets, which are impacted upon by the blast of steam and atomized. The force of the blast also draws air through the perforated tube and the spaces in the spider, and the steam, oil, and air are thoroughly mixed lin the chamber b3 and projected into the .fire-box through passages h2, where it is subjected to cross-currents of steam from the steam-space Z218 before it enters the furnace. As soon as the boiler has generated steam of sufficient pressure, the oil-pipe C is closed and the supply of steam from drum A6 is cnt off, as steam can now be supplied to the injector B through the pipe as. If it be desired to superheat the steam passed to the injector B, the water is withdrawn Vfrom parts A5 and AVT by opening the waste-pipe AS and allowing the water to escape. The wastepipe is then closed and cock al in pipe a9 and cock al? in pipe al opened. Steam from the dome will now pass through pipe a, drum AT, pipe ai), part A, pipe a2, drum A, and pipe a" to the injector B, as well as directly through the pipe as to the injector B. rlhe heat in the fire-box will soon superheat the steam passing through part A5, and as soon as it is accomplished cock as is closed and all the steam supplied to the injector B must pass through the part A5 before it is used. By these means I am enabled in a few minutes to start and maintain a lire of sufficient power to supply the initial heat necessary to heat the boiler to the point at which it will give ol'f steam. of sufficient pressure to vaporize the oil without the use of other fuel, and this may be accomplished at any time and as often as desired.` This is a very important factor in using petroleum as a fuel. It obviates the necessity of providing other fuel and at the same time does not interfere with the proper disposition of the other parts of the apparatus. On the contrary, the device used forms an auxiliary which can be utilized as a superheater without any changes more than the changing of the position of a few cocks.

To pre vent the pipes from burning out when the steam-generator is used as a superheater, I provide an asbestus curtain or shield, D,

IOO

(shown in dotted lines, Fig. 1,) which is placed over the top of the pipes at such times.

I do not herein claim the form of atomizer described and shown, as that device forms the subject-matter of a separate application, Serial No. 266,903, filed March l0, 1888.

That I claim as new is* l. In an apparatus for burning hydrocarbons, the combination, with the ire-boX of a boiler, of a coil of pipe, A5, located in the fireboX, and having pipes a2 and a3, the water-drum A7, connected with pipe a3, the steam-drum A6, connected with coil A5 by-pipe a2, the pipe a8, leading from. the steam-dome and connected with drum A7 by pipe a4 and with steam-drum A6 by pipe al, the pipe a5, connecting pipe a4 with the water-space of the boiler, the injector B, connected with pipe a8, and the oil-supply pipe connected with the injector and having the branch pipe extending into the fire-box, substantially as described.
