" BAFFLE FOR STEAM-BOILERS.
SPECIFICATION forming part of Letters Patent No. 794,711, dated July 18, 1905. Application filed fieptemher 19, 1904. Serial No. 22 1,981-
To all whom it rncty concern:
Be it known that I, JosEPH S. HAMMER- 'SLOUGH, residing in Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented new and useful Improvements in Baiiies, Bridges, or Abutments for Steam- Boilers, of which the following is a descrip tion, reference being had to the accompanying drawings, which are a part of this specification.
My invention relates to an improved baflie, bridge, or abutment arch employed or to be employed in a boiler-furnace or steam-boiler,
especially a boiler having return combustion or smoke flues.
The object of the invention is to provide a bafile or bridge to be used in connection with the combustion-chamber of the furnace that is adapted to be filled with water from the boiler, whereby the baffle or bridge is protected against being burned out, the combustion in the combustion-chamber is made more complete and is better controlled, and where by a greater heating-surface and capacity to the boiler is obtained and a better circulation of the water in the boiler is secured.
The invention consists of the baffle or bridge and its combinations, as herein described and claimed, or the equivalents thereof.
In the drawings, Figure 1 shows my imat the rear end of a combustion-chamber in a return -flue boiler and secured detachably thereto, which boiler is shown fragmentarily in section. Fig. 2 shows my improved baffle or bridge in section located permanently in the rear end of the combustion-chamber of a return-flue boiler, which is shown fragmentarily in section. Fig.3 is an end view of the flue-plate and shell of the boiler and my improved bridge of the form shown in section in Fig. 1, and Fig. 4c is an end view of the return-flue sheet-plate and shell of the boiler with my improved bridge or battle in the form shown in Fig. 2.
In the drawings, 5 indicates the exterior cylindrical shell of the boiler. Within the boiler is the smaller cylindrical combustion-chamber shell 6, which at its front end and at the rear end is secured in place within and at a distance from the boiler-shell by a boiler or flue plate 7. The combustion-chamber 8 is encircled by and formed within the shell 6, and there is a water and steam chamber 9, which surrounds the combustion-chamber 8. Tubes 10 10, fixed at their ends in the flue or boiler plates 7 at the respective ends of the boiler, only one of which is shown, form flues for the return of the products of combustion from the rear combustion or smoke chamber 11 to the front end of the boiler.
The construction so far described is in common use, and therefore only so much of the boiler, combustion-chamber, and return-fiues are shown and described as is necessary to illustrate the use of my improved baffle or bridge. In boilers of this class the combustion-chamber is in elongated cylindrical form and is disposed in horizontal position, so that the products of the fire in the fire-box at the front end of thecombustion-chamber flow freely into and through the combustion-chamber into a smoke-chamber 11 and thence on through the fines 10 to a stack, chimney, or suitable outlet. Such free flow of the products of combustion from the fire-box through the combustion-chamber has heretofore been in a measure arrested or baffled by some sort of a bridge, arch, or similar device, usually made of brick and in a solid form, arrange at the rear end of the combustion-chamber to prevent the unlimited and undesirable free flow of the products of combustion through the combustion-chamber. My improved device consists of a hollow bridge, baffle, or abutment device located or adapted to be located in or near the rear end of the combustion-chamber, and, as shown in Fig. 1, may consist of a hollow annular ring or waterchamber 12, formed of boiler-plate or analogous material, so bent as to form an exterior circular and peripheral wall 13, opposing outer and inner walls 1 1, and an inner wall 15, thus providing a hollow device of such diameter or peripheral size as just to fit easily within the rear end of the shell 6, thus closing that end of the combustion-chamber, except to the extent of an inner opening or passage 16, around which on all sides there is the waterchamber 17 The opening or passage 16 peropening that is somewhat elongated laterally mits the outflow through this baflie, bridge, or abutment of only a limited amount of the products of combustion within the combustion-chamber 8, thus serving to retain the heat and products of combustion within the combustion-chamber until at least the process of combustion therein is completed. The waterchamber 17 is provided with apertures 18, and in the case of the form of device shown in Figs. 1 and 3 with water-ducts 19, leading from the chamber 17 to the water-chamber 9 of the boiler, so that there is a free flow of the water from the boiler into and through the chamber 17. By this means the walls of the bafiie are protected against being burned out by the heat of combustion, while at the same time the water in the boiler being permitted to flow freely into and through the baflie-chamber is thereby brought into additional and closer relations to the heat in the combustionchamber, whereby the water in the baflie-chamher being additionally heated is returned to the boiler, giving additional heat thereto. In other words, the baflie provides additional surface-exposed to the heat of the combustionchamber for heating the water of the boiler.
As shown in Figs. 1 and 3, the baffle may be conveniently formed of two sheets of boilerplate so cut and turned as to form the exterior peripheral wall 13 of the baflie, and the interior peripheral wall 15 about the opening 16 and the plates at their junction being secured together by rivets form the water-tight chamber 17. The form of the opening 16 in cross-section is not important, although an is a satisfactory one. The walls of the bafiie may also be held together and strengthened by transverse screw-bolts 20 in such numbers as may be deemed necessary. Also, advisably,
openings closed by any suitable and releasable means 21 are provided through the exterior wall of the baflie for permitting of its being cleaned out when the conditions demand it.
In the form of construction shown in Figs. 2 and 4 the baffle instead of being made de tachable from the boiler is constructed permanently therein by means of two plates 14 14 of proper size and form having their edges turned over and formed, respectively, into a flange, the plates being fitted into the shell 6 at a little distance apart and by means of their fianges 22 riveted to the shell 6, forming between them and within the shell 6 the water- -chamber 17. The inner passage 16 through the baffle is formed by turning adjacent portions of the plates inwardly toward each other and causing them to lap together, and being riveted to each other form the inner peripheral wall of the chamber 17 about the opening or passage 16. Stay-bolts 20 may also be employed in this form of bafiie to secure the walls in position relative to each other. In this form of device the apertures 18 are made through the wall 6 directly into the waterchamber 9 from the chamber 17.
What I claim as my invention is- 1. In combination, a horizontal steam-boiler having a combustion-chamber and a water and steam chamber about and inclosing the combustion-chamber and of substantially equal length, and an abutment in the combustionchamber at the rear end thereof consisting of v an independent hollow water-chamber entirely across and closing the combustion-chamber from front to rear except as to a single medially-disposed and relatively small passage for the products of combustion, relatively small water-passages being provided from the water chamber of the boiler into the chamber of the abutment.
2. In a horizontally-disposed steam-boiler having acombustion-chamber of substantially equal length within and longitudinally of the boiler, a hollow abutment forming a water chamber in and across the combustion-chamber near the rear end thereof, the abutment being provided with a single passage for the products of combustion therethrough below a larger portion of the water-chamber in the abutment.
3. In'combination, asteam-boiler with horizontally-disposed combustion-chamber of substantially equal length through it, and an abutment at the rear end of the boiler in and across the rear end of the combustion-chamber consisting of an independent hollow annular water-chamber formed of metal plates within and fitted to the encircling wall of the combustion-chamber and closing it to the passage of the products of combustion, except by a medial and relatively small opening or passage through the abutment from front to rear at a distance from the wall of the combustionchamber, the chamber in the abutment being connected by relatively small water-passages to the water-chamber in the boiler.
In testimony whereof I afiix my signature in presence of two witnesses.
