BOILER-FURNACE.
SPECIFICATION forming part of Letters Patent N o. 669,666, dated March 12, 1901. Application tiled January 8, 1901. Serial No. 42,498. (No model.)
To all whom it may concern.:
Be it known'that I, ERNST JOSEPH SCHMIDT, a citizen of Germany, residing at Hamburg, Germany, have invented certain new and useful Improvements in Boiler- Furnaces, of which the following is a specification.
This invention relates to a boiler-furnace in which an intimate admixture of the firevided with a grated sleeve b, which serves for the secondary supply of air.
dis the hurtle-arch set back at a proper distance from the tire-bridge.
The top of the dre-bridge c dips from one side toward the other side of the combustionchamber, the drawing Fig. 3 showing it inclined from left to right. The upper edge d' of arch d also dips from left to right, Fig. 4, so that in this way an increased opening of the fire-bridge is longitudinally in line with a reduced opening of the arch. The arch d is furthermore set obliquely to the longitudinal axis of the combustion-chamber, Fig. 2.
By the construction described greater quantities of tire-gases will pass over the right half of the fire-bridge than over theleft half, while the right side of the hurtle-arch' will offer a reduced opening for the passage of such gases. Thus the fire-gases must flow laterally as well as rearward, so that they assume a tortuous or diagonal course. This peculiar flow of gases will cause their intimate admixture with the air supplied by the hollow lire-bridge, so that an improved combustion is effected.
What I claim is A boiler-furnace provided with a fire-bridge that dips from side to side, and with an 0bliquely-set hu rtle-arch that also dips from side to side, to form a tortuous passage for the fire-gases, substantially as specified.
Signed at Hamburg, Germany, this 20th day of December, A. D. 1900.
ERNST JOSEPH SCHMIDT.
