FLORENTINE A. JONES, OF MALDEN, MASSACHUSETTS.
SPECIFICATION forming part of Letters Patent No. 360,887, dated April 12, 1887.
Application filed June 16, 1886.
To all whom it may concern:
Be it known that I, FLORENTINE A. J owes, a citizen of the United States, residing at Maiden, in the .county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Steam-Boiler. or
passed over and beyond the fuel and beyond the bridge-wall or partition which defines that portion of the furnace underneath the grate; and it further consists in the introduction of air or steam, or both, at a certain point or points, whereby I obtain a more thorough intermixing of this supplementary supply of air and steam with the gaseous products of combustion than has heretofore been achieved, and in consequence a more perfect and eco: nomical combustion of the fuel; and I accomplish this result by means of an obstruction, preferably in the form of a hanging wall perforated, substantially as shown, and which is placed a proper distance beyond the bed of fuel and its attendant bridge-wall (so called) in the usual coal burning steam-boiler furnace shown in the drawings; but in furnaces not employing a bridge-wall the end of the bed of fuel or a substitute for the bridge-wall may be used, in order that the products of combustion may be deflected and made to pass under the lower edge or bottom side of said wall or obstruction. V
It may be prdper to say that I make use of a hanging wall, and show such in the drawings, because I considerit preferable to a wall supported from the under side; but it will be understood that such a wall, or one of iron or any proper substitute of any suitable form, in place of the hanging wall shown, would come within the scope of this invention.
I am aware that both air and steam have been supplementarily admitted to furnaces at different points and in different manners; but
Serial No. 205,353. (No model.)
I am not aware of its having been done in the. manner, or, more particularly, under the con ditions, that I have herein set forth, and by which I am enabled to achieve a result hitherto unattained.
In the accompanying drawings, in which similar letters of reference indicate like parts, the for-in of boiler shown is the usual form of tubular boiler and setting, wherein heat is applied to the outside of the shell on the under side, the fire-box. being situated under the front end of the boiler, and the heat and products of combustion passing to the rear of the boiler, then returning to the front through a series of tubes which traverse the boiler longitudinally, and pass off through the uptake and flue into the chimney.
Figure l is a longitudinal vertical section of a boiler and furnace. showing my improvements therein. Fig. 2 is a longitudinal vertical section of a boiler and furnace, showing my improvements therein. Fig. 3 is a cross section of Fig. 2 on line x 00, showing passages g for the admission of air into the bridge-wall D. Fig-4 is a cross-section of Fig. 2 on
line 2 2, showing passages b for the ad mission of air into the hanging wall E. Fig. 5 is a longitudinal vertical section of a boiler and furnace embodying my improvements, showing perforations or passages c a through the top and s 8 through the rear side of the bridge-wall, with the hanging wall E, provided with perforations 0 'v on the under side and r r on thefront or draft-opposing side. Fig. 6' is alongitudinal vertical section of a boiler-furnace embodying my improvements and showing two hanging walls, E and N, with asteam-pipe, y, connectingwith the wall N, which is perforated at o 'v and r 1'. Fig. 7 is a longitudinal vertical section of a boiler-furnace, showing the deflecting-wall E placed farther in the rear of the bridge-wall and supplied with heated air and superheated steam by the flue e and pipe 3 Fig. 8 is a cross-section of Fig. 7 on line :0 :0, showing pipe 3/ arranged to superheat steam and its connection with the hotair flue c.
F represents the boiler, f f f the tubes, and A the setting or brick-work; i, the door to the fire-chamber, and Z the door to the ash-pit. B is the ash-pit; a, the grate-surface; G, thefire- ICO chamber; D, the bridge-wall; K, the combustion-chamber; I, an inclined wall, and L the filling. G is the uptake or flue, and H the chimney.
In the drawings showing the bridge-wall provided with the air-chamberp, passages for the entrance of air are shown at g in Fig. 3.
E is a hanging wall or obstruction placed in the rear of the bed of fuel at any convenient point, and provided with a hollow space or chamber, P, and perforations 'v I) through the bottom or lower side, and in Fig. 5 the wall E is shown with additional perforations, r r, on the front or side opposing the draft, while in the same figure the bridge-wall will be seenprovided with perforations in the rear at s s and on the top at c 0, these perforations connecting with the chamber 1) in said wall. The connection of the chamber 1? in the wall E with air-supplying passages is shown in Fig. 4 at b.
In Figs. 6, 7, and 8, where a deflecting-wall is shown at or near the rear end of thcboilcr, it will be seen special means have been taken for the admission of heated air or steam, or both and Fig.8 shows how steam may be superheated.
The operation of my improved furnace is as follows: The products of combustion arising from the fuel on the grates a in the fire-chamher 0 pass with the draft over the bridge-wall D, and are arrested and made to pass under the lower side of the hanging wall E, where they come in contact with air or steam coming through the perforations v 'v in the lower side of said wall E, and passing through the combustion-chamber K to the rear of the boiler F, and thence through the tubes fff into the flue or uptake G into the chimney H.
It will be observed that in perforating the retardingwall E on its under side the products of combustion are forcibly made to pass in contact with the air coming through the perforations o o, and its importance will be readily understood.
The supply of air to the chamber P in the wall E should be greater than can pass through the perforations, which should be so constructed as to discharge at a certain angle downward and outward on the draft-opposing side, or a longitudinal separation may be put in the chamber 1, between the side perforations and the bottom perforations, to prevent the combusti ble products from passing through the wall E, which would be contrary to the spirit of this invention. It is also well to incline the bottom perforations of wall E slightly to the rear, as they discharge freer and keep open better.
Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is
1. In combination with a furnace, a hollow deflecting-wall provided with perforations extending from the interior outward through the under face, said wall being situated on a line parallel with the rear face of the bridge-wall and to the rear of an open space behind the bridge-wall and adapted to arrest and deflect the products of combustion downward and underneath the lower face of said hollow wall after they have passed over and beyond the bridgewall, substantially as and for the purpose set forth.
2. In combination with a furnace, a hollow deflecting-wall provided with perforations extending from the interior outward through the under face and with perforations extending from the interior of said wall outward through the side opposing the draft, said wall being situated on a line parallel with the rear face of the bridge-wall and to the rear of an open space behind the bridge-wall and adapted to arrest and deflect the products of combustion downward and underneath the lower face of said hollow wall after they have passed over and beyond the bridge-wall, substantially as and for the purpose set forth.
3. In combination with a furnace, a hollow deflecting wall or walls provided with perforations extending from the interior outward through the under face and with perforations extending from the i nterior of said wall or walls outward through the side opposing the draft, said wall or walls being situated on a line parallel with the rear face of the bridge-wall and to the rear of an open space behind the bridgewall, and adapted to arrest and deflect the products of combustion downward and underneath the lower face of said hollow wall or walls after they have passed over and beyond the bridge-wall, substantially as and for the purpose set forth.
