Description: |
| Abstract:
The object of the invention is to construct a fire-box in which straw may be consumed without producing dust to fill up or clog the tubes of the boiler; and it consists, essentially, of a fire-box having its upper portion where the flues enter, partially separated from the lower portion by a hollow chamber extending from to tube-sheet to a point near the opposite side of the fire-box and provided with openings leading to the outside of the boiler to admit air, which is heated in the chamber and enters the fire-box though perforations in the chamber at a point where the heated gases pass on their way to the tubes.
Claim:
A fire-box having its upper portion, where the flues enter, partially separated from its lower portion by a hollow chamber extending from the tube-sheet to a point near the opposite side of the fire-box and provided with openings leading to the outside of the boiler to admit air, which is heated and escapes into the fire-box at the point where the smoke and heated gases pass the hollow chamber.
