FURNACE.

Specification of Letters Patent.

Patented Jan. 16,1912.

Application led January 14, 1910. Serial No. 538,006.

y coal or fuel, provision being made to supply the latter with combustible vapor above and below the bed of fuel, so'as Vto cause more perfect combustion and a high degree of heat; provision being made also for combining air and steam and directing the same to the fire as a powerful draft of comb-ustible vapor, and furthermore of means for utilizing the products of combustion in the smoke flue, heating said air and steam, andy for heating the water from which said steam is produced prior to admission into the generator.

For the purpose of explaining the invention, the accompanying drawing illustrates a satisfactory reduction of the same to practice, but the important instrumentalities thereof may be Varied, and so it is to be understood that the invention is not limited to the specific arrangement and organization shown and described.

Figure 1 represents a perspective view of a furnace embodying my invention. Fig. 2 represents a vertical section thereof. Fig. 3 represents a horizontal section on line m-m Fig. 2.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings 1 designates the casing of a furnace, 2 the ash pit thereof, and 8 the grate bars thereof, the latter being pivotally mounted on the casing 1, and connected with and coupled by the stringers 4, which are provided vwith the lever 5, whereby the said stringers and consequently the grate bars may be operated for raking purposes, said lever being mounted at 6 on the exterior of the casing 1, and thus convenient of access.

Interposed between the bars 3 and supports on the wall of the casing, are pipes 7, having jets 8 on the upper side thereof, said pipes having connected with them the tubes 9 which extend through the side of the casing and communicate by means of the being secured to the exterior of the casing and adapted to contain hydrocarbon or other fluid which is to be vaporized being injectedfagainst the fuel on the grate bars and burned therewith, thus intensifying the resultant heat, said pipes 7 being heated by the fire and hot air injected into the ash pit, as will be hereinafter more fully described.

The furnace has doors 13 above the grate bars for usual purposes; and the plate 14 for closing the ash pit air tight, the same being held in position by the yoke 15, which is pivotally connected with the casing 1, and the screw 16 which is fitted to the front ofsaid yoke and adapted to tighten against said plate. When the screw 16 is loosened,

the yoke 15 may be made to allowT the plate 14: to be withdrawn, thus uncovering the openings of the ash pit and permitting access to the interior of the latter.

In the combustion chamber 17 are the pipes 18, which are supported on the wall of the casing, the same having jets 19 on the upper side thereof, said pipes having connected with them the tubes 20 which extend through the side of the casing and compipes 10 and 11, with the tank 12, the latter municate by means of the pipes 21 and 22 with the tank 23, the latter being secured to the exterior of the casing and adapted to contain fluid or material whichmay be converted into a combustible vapor in the pipes 18 and injected by the jets 19 into the chamber 17, where it is consumed with the products ofv combustion, thus further intensifying the heat of the furnace.

24 designates the smoke iue the same extending from the top of the casing and having an elbow which opens to the atmosphere, one limb of the elbow containing the coil 25 shown in dotted lines Fig. 1, one end of said coil having connected with it the air supply pipe 26, and the ot-her end having connected with it the air conveyer pipe 27, the latter extending to the blower or blast apparatus 28, which opens as at 29 into the ash pit 2.

A pipe 30 is connected with a source of steam, in the present case, the boiler or generator 31 and is connected with the air pipe 26 and whereby steam and air are directed into the coil 25, and as the latter is contained in the smoke flue 21 which is heated by the produ cts of combustion, the steam is nace with a powerful draft and a vaporil which is directed to the fuel, to assistthe combustion 'thereof to a high degree while also highly heating the pipes 7 for Vaporiz-A ing the hydrocarbon fluid therein. Y

In the smoke flue 24 is acoil 82 with one end of which is connected the pipe 33 for directing Water into the steam generator,` the other end of said coil having connected with it the pipe 34 which -passes through said iue and the adjacent wall of the casing into the generator, it being noticed that the products of combustion in said fiue 24 are utilized to heat the coil 32 and adjacent portion of the pipe 34 thus heating the feed water of the generator before entrance into the latter.

Having thus described my invention',

what I claimy as new and desire to secure by Letters Patent, is

A furnaceV having. grate bars, a tightly closed ash pit,`1neans for supplying a blast of air and steam .below said grate bars, means for heating said' air prior to its entrance to said blast-supplying means, oil

ingtubes.
