ISAAC H. BOYER, OF MUNGIE, INDIANA.
IBOILER-FURNACE.
Application filed January 24, 1906.
To all whom it may concern.
Be it known that I, lsAAo H. BOYER, a citizen of the United States, residing at Muncie, in the county of Delaware and State of Indiana, have invented new and useful Improvements in Boiler-Furnaces; and I do declare the following to be a full, clear, and
exact description of the invention, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.
This invention relates to apparatus whereby steam may be produced by the combustion of fuel, the invention having reference particularly to apparatus comprising a furnace, a boiler for the water that is to be converted. into steam, and to minor features of construction and arrangement of elements.
Objects of the invention are to provide a steam producer of improved construction and capacity adapted to limited ground spaces to provide apparatus whereby steam may be produced with a relatively small furnace grate area and with the minimum consumption of fuel; all to the end that steam may be produced at the minimum cost.
With the above-mentioned and minor objects in view, the invention consists in the novel construction and arrangement of features embodied in the apparatus hereindescribed; and the invention consists further in the parts and combinations of parts as hereinafter particularly described and claimed.
Referring to the drawings, Figure 1 is a sectional elevation of the improved steam producer, of which theleft-hand side is a half front elevation with parts broken away and exposing the fronts of forward waterheads, and the right-hand side is a transverse vertical half section beyond the forward water-heads, (as on the line AA in Fig. 3,); Fig. 2, a transverse vertical half section through the forward water-heads, (as on the line B-B in Fig. 3,); Fig. 3, a vertical longitudinal sectional view of the complete apparatus as on the line CC in Fig. 1; Fig. 4, a horizontal sectional view showing two half-sections on two different planes looking downwardly, the upper halfsection being on the line DD, and the lower half-section. being approximately on the line EE including a feed-pipe slightly above said line, in Fig. 3; and, Fig. 5, a horizontal sectional view showing two half sections on two different planes looking Specification of Letters Patent.
Patented May 19, 1908.
Serial No. 297,597.
downwardly, the upper half-section being on the line FF, and. the lower half-section being 011 the line GG, in Fig. 3.
Similar reference characters in the several figures of the drawings designate corresponding elements or features.
Practically embodied, the improved steam producer comprises a front Wall at having preferably an ornamental metallic facing or front a; a rear wall, I); a rear furnace wall, 0; furnace doors, (Z; ash-pit doors, d; and grates, e. The rear wall 0 has a fire-brick lining having projections f that have flat outer faces and beveled sides so as to rapidly absorb and radiate the heat from combustion on the grates. Also there are side walls 41 and i and a partition wall i and arches g extend from the front Wall inwardly, resting on the side walls and the partition wall, the arches being composed of bricks built up and having projections g on the upper and lower sides thereof consisting of projecting bricks. Other arches it having projections h on the upper and lower sides thereof rest on the side walls and the partition wall and extend forwardly from the wall 0 slightly above the arches g, leaving a heat passage between the arches g and 7t and combustion chambers above the arches g and it, there being a heat passage extending thence to and over the wall I) under the evaporator, which will be hereinafter described, the heat passage having a floor on the top of which are projections 76 formed of bricks set so that parts thereof project beyond adjacent bricks of the floor, the passage thus constructed being relatively close to the evaporator, and the projections being adapted to quickly absorb and radiate the heat, not only aiding in combustion but affording augmented radiation of heat to the evaporator.
A forward main Water-head H is mounted on the front wall a and a key-bar Z of I-beam iron is laid flatwise on the water-head. A
water-head H for the primary heater is setupon the key-bar Z and is provided with a horizontal partition m dividing the waterhead into a lower chamber p and an upper chamber p with the latter of which an inlet pipe n is connected. The chamber p has a blow-off pipe 6, the chamber p a blow-off pipe 7, and the water-head H a blow-off pipe 8.
In the top of the rear wall Z) is an li-beam reinforcing the top of the wall on which posts 7" are supported against the side walls of the structure, leaving a draft-passage between! the posts. A rear water-head 1 having shoes 8 at the ends thereof extends above the rear wall and forms the top of the draft-passage, the shoes bearing on rollers t that are supported on the posts 7".
A pair of evaporators, each comprising principally a tubular shell J and J respec' tively, have their shells attached to the inner walls of the water-heads H and 1, so that the water-heads form the ends or heads of the shells. The walls of the water-head I are protected above the water-line by fire-brick covers a, u and o, and a flue-wall w is erected opposite the water-head and extends somewhat higher than the top thereof.
Above the water-head 1 a steam-head K is supported by the side walls t and i and forms the top of a draft-passage over the top of the water-head 1 extending from the wall q along the wall to, the bottom of the steamhead being protected by removable firebricks a: that are supported preferably by the steam-head. Fire-brick covers i are provided for the shells J and J. An I-beam is laid flatwise on the top of the steam-head, providing a key-bar z, and upon this is placed awater-head L for the primary heater, the top of the water head L being at the same elevation as the top of the water-head H opposing it.
For superheating the steam, a series of tubes M form a superheater, the tubes being connected to the water-head H and extending through a heat passage above the shells J and J and connected also to the steamhead K, being preferably inclined as shown.
The primary heater comprises, besides the water-heads H and L, a series of tubes N that are connected to both of the waterheads and preferably are inclined, and beneath these is a horizontal baffle-wall O suitably supported and extending a suitable distance from the water-headL forwardly toward the water-head H, forming a roof for the heat chamber or passage in which the superheater is arranged, and also a draft passage near the water-head H for the hot. gases to ascend up among the tubes N. Another series of tubes P are arranged parallel to and above the series N and connected to the water-heads H and L. A baffle wall Q is placed between the series N and P of the tubes, being inclined as they are, and extending rearwardly a suitable distance from the water-head H toward the water-head L, leaving a draft passage around the end thereof adjacent to the water head L. Above the series P is a baffle wall R that extends from the water-head L forwardly a suitable distance toward the water-head H, there being a draft passage between the end of the bafile wall and the latter Water-head. The two series of tubes N and P are connected with the chamber p of the water-head H.
Another series of tubes S are connected with the chamber 19 of the water-head H and also to the water-head L, and above these tubes a roof 9 is provided that forms the top of the uppermost draft passage between the various tubes S to the chimney connection 10 that is provided near the top of the waterhead L.
A feed-pipe T provided with a regulatingvalve 11 is connected to the water-head H and extends at the front of the structure downwardly to the water-head H, but has no communication therewith, the water head having a thimble 12 through which the pipe extends as combined feed-pipe and primary heater T between the two shells J and J to the water-head I to which it is connected, the pipes T and T being formed of two connected parts. A safety-valve pipe 13 is connected to the water-head H, and an outlet-pipe 14, for conducting the steam away for use, is connected to the steamhead K.
Each evaporator shell J and J has stirrups 15 within it supporting a series of tubes U somewhat above the bottoms of the shells, the tubes having a cap 17 at either end thereof and being open at the opposite end thereof; and upon the tubes a series of steam-vessels V formed of tubes are arranged and secured by clamps 16, the vessels having upturned open ends 18 and 19 extending above the water-line, which is approximately at the axis of the shell, so that steam may enter and circulate through the vessels while water will be excluded. In each shell, J or J, in a plane above the steam vessels are a pair of supports W attached to the sides of the shell and having perforations 20 therein. A foam-arrester composed of sections of plates X having perforations 21 therein is arranged on the supports, so that foam rising with wet steam may be broken up before it can progress to the water-head H or the superheater tubes M. The plates X and the vessels V and tubes U may be re moved when cleaning is required.
Various modifications may be made fairly within the scope of the invention, as to the number of partition walls and arches in the furnace, and the number of chimney connections. Also, the steam vessels V may rest directly upon the tubes U or be slightly separated therefrom by parting strips.
In practical use, the water will be admitted through the connection it to the chamber p of the water-head H, and will circulate through the course indicated by feathered arrows to the water-head L, then to the chamber 20 of the water-head H, and thence through the pipes T and T to the water-head I and then into the shells J and J and waterhead H. The steam formed will rise in the shells of the evaporator and flow to the upper part of the Water-head H and then through the superheater into the steam-head K to be drawn therefrom as may be required, it being understood, of course, that combustion is assumed to be taking place in the furnace; and when the water has reached the desired level in the evaporators and connected water-heads, the valve 11 will be closed, and will thereafter be used to regulate the water supply as occasion may require. The furnace heat will be applied directly and confined closely to the evaporator shells, and while still at high temperature, after doing what is required in converting the already hot water into steam, will pass between the tubes of the superheater and thence between the tubes of the primary water heater, so that the heat units may be utilized to the fullest extent during the unavoidable passage of the waste gases to the chimney, with the result that, since the water enters the evaporators at a high temperature, it may be the more readily converted into steam with the expenditure of the least amount of fuel for the production of the steam.
Having thus described the invention, what is claimed as new is 1. A furnace comprising a front Wall, a
rear wall, a bridge wall between the front wall and the rear wall, grates, an inclined heat passage floor extending from the top of the bridge wall upwardly towards the rear wall, and a plurality of oppositelyextending arches, one arch extending from the front wall upwardly in an inclined angle and another arch extending from the bridge wall upwardly above the end of the first-mentioned arch and having projections on the under side thereof extending downwardly towards the grates and the front wall.
2. A furnace comprising a front wall, a rear wall, a bridge wall between the front wall and the rear wall, a cylindrical evaporator extending over the bridge wall, a heat passage floor extending from the top of the bridge wall upwardly towards the shell and the rear wall and curved upwardly at a side of the shell, and bricks projecting from the top surface of said floor In testimony whereof, I affix my signature in presence of two witnesses.
