BOILER-FURNACE.
SPECIFICATION forming part of Letters Patent No. 292,751, dated January 29, 1864,
Application filed September 29, 1882. (N0 model.)
To all whom it may concern:
Be it known that I, THOMAS E. J ONES, a citizen of the United States, and a resident of the city of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Boiler-Furnaces, of which the following is a specification.
My invention relates to an improvement in boiler-furnaccs; and its object is to provide a cluster of refractory pillars'or posts within the reverberatory throat-way of the combustionchamber, intermediate the bridge wall and the rear end of the boiler .to act as partial obstructions therein, and thereby check the too rapid passage of the smoke and gases coming from the fire-box and utilize them by the heating of said pillars.
My invention is especially designed for use in connection with the devices shown and described in Letters Patent of the United States No, 263,182, granted me August 22,1882 but it is obvious that from the following description it can be applied to any other boiler-furnace of a like class and with great efficiency.
In the accompanying drawings, Figure l is a longitudinal sectional elevation of a boilerfurnace, showing the preferred form of devices embodying i'ny invention on line 7 3 Fig. 2. Fig, 2 is a sectional plan of the same on line 00 :0, Fig. 1. Fig. 3 is a broken sectional elevation of the rear end of a boiler-furnace, showing a modified form of refractory pillars in the combustion-chamber 011 line 3/, Fig. 4. Fig. 4 is asectional plan on line w w,
Fig.3.
A represents an ordinary steam-boiler, B
the side walls, and O O the front and rear walls upon which it is mounted.
D is the fire-box, d the grate-bars, and D the ash-pit.
E is the bridge-wall, built in the usual manner, or with the side inwardly-projecting walls, F F.
It will be unnecessary for me to describe herein the steam and air injecting devices shown in the drawings, as they are the same as those shown and described in said former Letters Patent. 1
G represents an expanding-chamber having an inclined bottom,g and located between the bridge-wall and the pillars H.
H represents vertical refractory pillars or mond-shape bricks or tile-blocks h, which 7 bricks are perforated at h, thereby forming a hollow pillar that can be rapidly heated by the heat from the fire-box. Perforations or openings It also serve to obviate the cracking or breakage as much as possible of the bricks composing said pillars. Sand or other suitable material may be placed in the openings h of the pillars to prolong the heat therein. Instead of making the pillars of diamond-shape, they may be made of any polygonal form in cross-section, or they may be hollow cylinders I, made of stone or fire-claysuch as drainpipe, as shown in Figs. 3 and 4Lwhich may also be filled with sand for the purpose hereinbefore described. The pillars when made of brick are built from the floor 9 up to or near the bottom of boiler A and when they are cylinders, as in Figs. 3 and 4, their lower ends are set into the ground, as shown in cross-section at J, Fig. 3.' a
The arrows in Fig. 4 indicate the refractory action of the smoke and gases against and between the heated pillars in the combustionchamber, which pillars effectually consume to as great a degree as possible all such smoke and gases emitted by the fuel in the fire-box that may pass the bridge-wall into the combustion-chamber.
It is evident that by the arrangement of the pillars Hin the reverberatory throatway combustion-chamber herein shown and described the draft of the furnacewill not be materially affected.
From the foregoing it will be seen that by arranging the pillars in zigzag lines tortuous passages are formed through the cluster of pillars, so as to retard the products of combustion. Heretofore a boiler-furnace has been provided with a cluster of pillars arranged back of the fire-chamber and set in zigzaglines, but in such case an arch is superposed on the tops of said pillars but in my invention the pillars are unconnected at their upper ends, whereby the boiler is exposed to the direct action of heat inthe tortuous passages.
I claim- In a boiler-furnace having a fire-place and a combustion-chamber separated from each other by a transversely-arranged bridge-wall, and having an expandingchamber having passages formed through the cluster of pillars, whereby the products of combustion are retarded, and at the same time the boiler suban inclined bottom and located between the jeeted to the direct action of the heat in the bridge-walls and the pillars H, the herein-described set up upright refractory pillars H, unconnected at their upper ends, and placed in a cluster under the boiler at or about the center of the combustion-chamber,between the rear end of said chamber and the bridge-wall, these pillars being arranged in zigzag lines, and the boiler being exposed to the tortuous passages, substantially as described.
In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
