MARIA MEANS FOR BURNING PEAT, &c., IN STEAM AND HOT-AIR FURNACES.

' SPECIFICATION formingpart of Letters Patent No. 278,209, dated May 22, 1883.

Application filed July 15,1882. (No model.) i

To all whom it may concern Be it known that I, WILLIAM E. WRIGHT, acitizen of the United States, and a resident of Rome, in the county of Oneida and State of New York, have invented a new and valuable Improvement in Means for Burning Peat and Lignite in Steam and Hot-Air Furnaces; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same; reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure 1 of the drawings is a side view, part sectional, illustrating my device; and Figs. 2.; 3, and 4 are detail views.

This invention has relation to feeding fuel to boiler-furnaces; and it consists in the construction and arrangement of parts, as will be hereinafter fully described and claimed.

It has been found that lignite and peat are deficient in some elements ofcombustion which are requisite for producing a heating-power equal to some kinds of coal, although both are to a certain extent quite useful. It therefore becomes necessary to supply some additional element or elements which shall compensate for this deficiency.

It is the object'of my invention to supply such required elements as will more than suffice the intended purpose, and to derive the same from a source which would otherwise be wasted, and which, in actual operation, is constantly on hand and obtained without extra cost. To such end I utilize the ex hauststeam from the engine, and inject or direct the same into the fire-boxor'furnace along with the pulverized peat-or lignite which constitutes the fuel. I may employ live steam conveyed by a pipe or pipes connecting the boiler with the fire-box, but have not shown said construction herein, deeming it unnecessary, as any one skilled in the art can make the necessary connections.

The peat or lignite which I employ is previously treated as set forth in the Letters Patent heretofore granted to me, and numbered 161,466, or the same can be treated according to any other approved method, and pulverized into a fine powder by any suitable machinery, so as to .be ignited instantaneously by being blown into thefire-box or furnace by either a blower or by the force of steam-pressure. In the annexed drawings, in which I have illustrated my invention as applied to an ordinary locomotive-furnace, A indicates the boiler; B, the smoke-stack; (J, the fire-box,

and D the tender; S, the steam-cylinder; T,

the exhaust-pipe. in any ordinary way, and need not'be further described.

E indicates a pipe leading from the usual exhaust of the engine back through or outside the boiler and through the fire-box to the tender, where it connects with the casing of a blower, F.

G indicates a second pipe leading from the blower to the fire-box or the furnace.

. H indicates a third pipe, which leads from the pipe E, at a point in rear of the fire-box, up to a hopper, I, which is located above the fire-box or the furnace and communicates therewith. The exhaust-steam passes back, through the pipe E, and is heated on its way while being conducted through the boiler and the fire-box. The dry steam enters the blower,

then passes forward to the fire-box through the pipe G, carrying with it.the pulverized peat or lignite, which enters the blower and pipefrom the tender thron gh suitable passages, K, between the said two members. The pulverized peat or lignite is injected into the firebox or furnace, and the steam impinging against the decomposer L is effectively decomposed.- This decomposer, which is located within the fire-box, can be constructed of a perforated iron plate having a tapering hollow thimble, d, preferably squarein cross-section, foreach perforation, so that the steam directed against said perforated platewill enter the heated thiin bles and be thereby rapidly decomposed.

The pipe E is provided with a cock or valve, M, and the pipe G will also be provided with a valve, so that the pipes can be opened or closed when required.

The rotary shaftNot' the blower-fanis driven in any suitable way from oneo f the axles-as, for example, by means of a belt, O-and the blower is supported from the tender in any convenient way.

An inverted funnel, P, is placed over the These are all constructed 7 furnaces, and that in all cases there will be a 2 msgzoa exhaust and inlet end of pipe E in the smokestack, so as to collect any surplus exhauststeam which may occur.

In lieu of making the decomposer of metal, I can form it of fire-brick, built so as to leave numerous small openings through it, and in such case the thinibles could be dispensed with. i

In case it is not desired to feed from the tender, the blower will be dispensed with and the live steam conducted from pipe E into pipe H, and thence into the hopper 1', into which latter the pulverized peat or lig'nite to be fed into the fire-box on the furnace will be placed.

It will be evident that my invention can be used in connection with all varieties of locomotive or stationary engines and metallurgic great increase and saving of heat and fuel, as applied to these purposes.

Having thus described myinveutiom what I claim is p 1 The combination, with the fire-box or fur-. nace, of a pipe leading from the exhaust through or outside the boiler and through the fire-box to a blower, a pipe leading from the blower to the fire-box 0r furnace, and means for introducing pulverized peat or lignite into the blower, whereby the same is carried along with the steam into the'fire-box or furnace, substantially as described.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.

WILLIAM ELY WRIGHT.
