BOILER-SETTING.
QPECIFICATION forming part of Letters Patent No. 484,878, dated October 25, 1892.
Application filed August 21, 1891. Serial No. 403,270- (No model.)
To all whom it may concern.-
Be it known that I, MARSHALL F. EATON, of Chicago, in the county of Cook and State of Illinois, have inventedcertain Improvements in Boiler-Settings, of which the followlng 1s a specification.
Y This invention relates to improvements in the settings of steam-boilers; and the objects I have in view are to provide a furnace in which a steam-boiler may be set which will require a minimum amount of fuel, will secure the application of the greatest amount of heat to the boiler itself, and will produce a substantially-perfect combustion of the fuel.
To this end the invention consists generally in the construction and combination hereinafter described, and particularly pointed out in the claims.
In the accompanying drawings, forming a part of this specification, Figure 1 is a side elevation of a boiler with the brickwork or setting in section. Fig. 2 is a horizontal section on the line y y of Fig. 1. Fig. 3 is a ver-' tical section on the line a; of Fig. 1. Fig. 4 is'a detail of one of the steam and air pipes. In the drawings, 2 represents the boiler, which maybe of any preferred form and construction. This boiler is arranged in the f urnace or setting 3, which is preferably formed of brick and is constructed as hereinafter described.
5 represents the fire-box, provided with a grate 7,beneath which isthe ash-pit 9. The firebox and the ash-pit are preferably provided with the floors 11 and 13. These parts may all be of any ordinary or preferred construction. The furnace or setting is constructed so as to leave a series of annular spaces 15 passing clear around the boiler. These are formed by constructing the brickwork with the halfcup, as shown clearly in Fig. 3. A series of arches 17, that are arranged close to the surface of the boiler, separate the spaces 15 from each other. Arranged in the rear of the firebox is the wall 19, and in the rear of which is the settling-chamber 21. At the bottom of this chamber is a conveyor 23, that is arranged to be operated by handles from the outside of the furnace, and in this chamber the cinders and material of like nature will settle. Back of the settling-chamber 21 is V the vertical wall 27, provided with the arch or arches 29. This wall supports the central portion of the boiler and it causes all of the products of combustion to pass downward, so as to go through the arch or arches. The wall 19 is provided with the air-inlet pipes 31, that extend from the front of the furnace, through the walls thereof, on each side of the combustion-chamber and then pass through the wall 19 and have their open ends extending through the rear of said wall directly opposite the arches 29. Other air-pipes extend from the front of the furnace through .the side walls to a point substantially over the settling-chamber 21. At this point they open through the interior wall of the furnace, as shown in Figs. 1 and 3; A steam-pipe 37 leads from the steam-dome 39 and at its ends it is provided with the branch pipes 41, that project into the open end of the pipes 35 and 31. By this means a current of air is drawn into each of the pipes 35. It is partially heated by the steam by which it is driven through the pipe and partially heated by extending through the heated walls of the furtional oxygen is mingled with the heated product of the combustion and aids in further combustion thereof. The products of combustion are also forced downward, so as to bring them directly in front of the air-blasts through the pipes 31. By this means a substantially-perfect combustion of the fuel is obtained. The products of combustion that are not consumed, after passing the arches 29, must also pass through the arches 45, arranged in the wall 17 at the rear of the boiler. After passing through these arches the remaining products of combustion are returned through the boilerdoes 49 to the smokepipe 61.
The heated prodiicts of combustion from rear of the Wall 19 and midway in front of up and around the boiler, to pass down again and through the arches 45, and thus finally reach the dues of the boiler.
This boiler-setting is simple and economical in construction,will give the greatest effioiency for the amount of fuel consumed, and will produce a practically-complete combustion of the fuel.
I claim as my invention- 1. The combination of the boiler and the combustion-chain ber provided with the transverse wall 19, the wall 27, provided with the arch or arches 29, the transverse settlingchamber 21, arranged between the wall 19 and the wall 27, and the conveyor 23, arranged at the bottom of said settling-chamber for withdrawing the cinders from the same, substantially as described.
2. The combination, with the boiler and the furnace provided with a combustion-chamber and the wall 19, of the ainpipes 31,extending from the front of the furnace longitudinally through the side walls thereof, to be heated, into the transverse wall 19 and having an opening through the rear thereof, the pipes 35, extending through the side walls of the furnace and opening into the combustionchamber from opposite sides thereof at the rear of and above the wall 19,and smaller steam-pipes extending into said pipes 31 and 35, whereby heated air and steam are discharged into the furnace back of the'wall19, substantially as described.
3. The combination, with theboiler, of thecombustion-chamber provided with the transverse wall or bridge 19, the wall 27,provided with the annular openings or arches, thelower parts of which lie below the line of the top of said wall 19, the pipes 31, extending through the side walls of the combustion-chamber, and openings into the combustion-chamber at the 7 said arches 29, and the pipes 35,'opening into the combustion-chamber through the side wallsthereof and in front of the arches 29, substantially as described.
4. The combination, with the boiler, of the combustion-chamber, the transverse wall 19,
forming the bridge, the wall 27, arranged back of the same, the settling-chamber 21, formed between the walls 19 and 27, having the hopper-shaped bottom, the rear wall arranged beneath the rear end of the boiler, whereon the same is adapted to rest, the chamber provided between the same and the rear wall of the furnace, and the annular opening or openings or arches 29 and 45, arranged in said wall 27 and the wall supporting the rear end of the boiler, the top of said transverse or bridge wall 19 being considerably above the level of the lower parts of said openings, whereby the gases and flames from the combustion-chamher are forced down just back of the bridgewall and again at the rear end of the boiler, and means for removing cinders from the bottom of the settling-chamber, substantially as described.
5. The combination, with the boiler, of the furnace having the combustion-chamber, the inclosing front, side, and rear walls and top, spaces 15, divided by partitions 17, being formed transversely about the boiler, the
transverse or bridge wall 19, the settlingchamberformed back of the same, the wall 27, provided in its upper rear part with the arches 29, therear wall 47, having the arches 45, said walls 27 and 47 having upward extensions adapted to close the spaces betwee'n'the sides of the boiler and the side walls, large air-pipes contained in the side walls of the furnace and opening through the front there of, said pipes having transverse portions extending within the wall 19 and-having inner ends opening at points midway between the sides and the arches 19, large air-pipes35, contained in the side walls above the pipes 31 and opening through said side walls and in front of the arches 29, and small steampipes projecting into the open forward ends of said air-pipes, all as and forthe purpose specified. y
-In testimony whereof I have hereunto set my'hand this 17th day of August, 1891.
