WILLIAM SILVESTER, OF PITTSBURG, PENNSYLVANIA, ASSIGNOR OF ONE- HALF HIS RIGHT TO W. WALTON, OF SAME PLACE.
IMPROVEMENT lN FURNACES FDR BURNING COAL-SLACK UNDER STEAM-B0lLERS| kc.
Specification forming part of Letters Patent No. 195,409, dated September 18, 1877; application filed March 9, 1877.
space surrounding the fire-box B. For the purpose of letting air above the fire, a second opening, (1, is left a little above the doors D D. It is closed by a hinged door, the same as the lower ones, and all are lined with firebricks.
Instead of introducing fuel by the doors D D, it may also be done from the side of the furnace by an opening. 0.
The circulation of cool air around the tirebox will reduce the temperature of the bricks. Small openings 6 c c e, communicating between the inside of the fire-box B and the surrounding space, may be established for the same purpose; but in this case the pressure of the blast must be very low.
The grate being constructed substantially as above described, its operation is as follows: Previous to the kindling of the fire a very light blast is started to prevent the clogging upof the pipes 0 0 0 0 by the fine coal, and only after the fire is burning more blast can '10 a, whom it may concern:
Be it known that 1, WILLIAM SILVESTER, of Pittsburg, in-the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Furnaces; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being bad to the accompanying drawings, forming part of this specification, and of which- Fignre 1 represents a vertical section taken at line a; w of Fig. 3. Fig. 2 is a front view, and Fig. 3 a horizontal section taken at line 3 of Fig. 1.
"he invention consists in the construction of a fire-grate with improved means for the purpose of burning slack coal for heating boilers or other furnaces.
In place of the ordinary burning-chamber with grate-bars, a tapered fire-box, B, having a perforated bottom, I), is substituted. It may be of any desired size, and is constructed of the usual materials. The inclined sides .9 s be turned on. surrounding the box B are hollow, and the The cleaning of the grate of ashes, 8250-, is latter may be of :a rectangular, circular, or done through the doorsD D. any other desired shape. The bottom I) is supi Having thus described my invention, what ported by a frame-work, and is made of cast- I claim as new isiron, lined with fire-bricks. A blast-chamber, 1. In a fire-grate for burning slack coal, the 0, receiving the blast through the pipe 19, is combination of the bottom b, lined with firelocated below the fire-box. By means of a bricks, and the blast-pipes 0 o 0 o fixed therennmber of small pipes, 0 0 o o, screwed into in, as described, and for the purpose set the chamber 0 and the bottom piece b, the forth. blast is directed below the slack coal,and thus 2. In a fire-grate, the blast-chamber G and facilitates the burning process. pipes o o o o, in combination with the bottom D D are doors for the introduction of fuel piece b, as described. and for the purpose set and the cleaning of the box. They are proforth.
vide-d with circular holes h it, through which an iron bar may be introduced to stir up the fire. Outside of the doors air-inlets a. a are provided, which communicate with the hollow WILLIAM SILVESTER.
