FURNAC E.
SPECIFICATION forming part of Letters Patent No. 310,582, dated January 13, 1885.
Application led August 11, 1884.
To @ZZ w/wm, it may con/cern:
Be it known that I, GEORGE GUnioKsoN, a citizen of the United States, residing in Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Furnaces, of which the following is a specification.
rIhis invention relates to furnaces for steamboilers, and its object is to effect a more complete consumption of the smoke and products of combustion and provide afurnace of simple and durable construction.
The invention consists in the novel devices and novel combinations of devices herein shown and described.
In the accompanying drawings, which form a part of this specifieation, and in which similar letters of reference indicate like parts, Figure l is a sectional side elevation of a device embodying my invention. Fig. 2 is a crosssection on line 2 2 of Fig. l, and Fig. 3 is a horizontal section on line 3 3 of Fig. l.
In said drawings, A represents the boiler, which is or may be of any usual construction; B, the grate; O, the re-box; D, the ash-pit, and E the combustion-chamber, which is sep-v arated from the fire-box by the bridge-wall F. The bridge-wall F extends nearly up to the boiler, the space between the top surface of the bridge-wall and the boiler preferably being only one or two inches. I
G G are a pair of egg-shaped tapering passages or ports leading from the re-box through the bridge-wall into the combustion-chamber, the larger end of th ese oval holes being turned outward, so as to better direct and distribute the heat to the sides of the boiler. As these ports G G are necessarily subjected to great heat, I provide them with an asbestus lining, g, which serves to protect the dre-clay or masonry.
In order to completely burn the smoke and products of combustion as the same issue into the combustion-chamber through these ports 'G G, I conduct a supply of hot air from the ash-pan through the air-passages H H, which meet the passages G G at or near their mouths, so as to commingle the air-supply with the products of combustion. In order to superheat this supply of air, Iaconduct it through a hollow convoluted-iron casting or tail-block, II, which is supported in the masonry of the (No model.)
bridge-wall, and projects out over the end of the grate-bars into the re-box, so that this curved or convoluted passage, being in contact with the re, will become highly heated. The air-passages H H connect with this hol'- low casting I-I. By this means the supply of fresh air from the ash-pit will be highly heated by the time it meets the products of Vcomlous- 6o tion issuing through the ports G G.
I is the mud-drum, connected to the boiler by the vertical pipe J. K is a shield or deflecting-plate, located above the mud-drum, and extending in front thereof on an incline, for the purpose of protecting the same, and also to deect the flame up against the boiler.
4Clhis deflecting-plate K may preferably be constructed of reclay or other refractory WA,
material, which may be supported on the iron 7o beams K, extending across the furnace and sustained by the side walls thereof.
As the mud-drum nozzle or tube J, which leads from the lowest point of the boiler to the mud-drum, is necessarily exposed to great heat, Isurround it with a protecting covering of asbestus, j, and I also place in front of it that is to say, between it and the iire-boX-a wedge-shaped hood or deiiector, L, preferably v made of fire-clay or like material, which will 8o serve to divide the flame or heat and distribute it to the sides of the boiler and shield the pipe.
To prevent the expansion and contraction of the metal boiler from rocking and moving the walls or masonry of the furnace, I insert a lining or packing of asbestus cloth or other elastic non-combustible material, M, at the joints between the metal and masonry, so that this elastic lining may take up the expansion 9c or contraction, and thus keep the joints tight without endangering the integrity of the masonry.
The hollow tail-block II', projecting out over the end of the grate-bars, not only serves to superheat the air which is delivered therefrom into the combustion-chamber, but it also serves to close the opening between the ends of the grate-bars and the bridge-wall, and thus prevent any coals or cinders falling down beroo tween the same.
I claim- 1. The'combination, in a furnace, of the firebox C with ash-pit D, combustion-chamber E,
@Ridge-wall F, provided With egg-shaped taperlg ports G G, extending through said bridge- Wgall, and having their larger ends turned out- WiardVsoas-to distribute the heat to the sides fthe boiler, and an air-passage leading from the ash-pit through the bridge-wall into the combustion-chamber at or near the mouth of said ports G G, substantially as specified.
2. The combination, in a furnace, of the irebox C With ash-pit D, combustion-chamber E, bridge-Wall F, provided with ports G G, convoluted air conductor and heater H', projecting from the bridge-Wall int the fire-box, and air-passages H, leading from said heater-passage H' into the combustion-chamber near the yports G G, substantially as specied.
3. The combination, with the lire-box, ash- Apit, and combustion-chamber, of the bridge- 5. The combination, with the fire-box, ashpit, and combustion-chamber, of the boiler, mud-drum, and connecting-pipe, said pipe being provided With an asbestus covering, and a delecting-plate located above said mud-drum, and a Wedge-shaped hood or detlector, L, located in front of said connecting-pipe, to divide the flame and shield the pipe, substantially as specified.
6. The combination of iire-box C, ash-pit D, combustion-chamber E, bridge-Wall F, passages or ports G G, leading through the same, and provided With asbestus lining g, air-heater casting or passage H', projecting into the nre-box, and air-passage H, leading therefrom to the eo mbustion-chaniber, substantially as specified.
7. The combination of grates B, fire-box C, ash-pit D, combustion-chamber E, bridge-wall F, and hollow tail-block H', projecting over the ends of the grate-bars into the fire-box, its hollow space communicating With the ashpit and combustion-chamber for the purpose of conveying superheated air into the latter, substantially as specified.
