SMOKE -CONSUMING ATTACHMENT FOR BLAST-FURNACES.
SPECIFICATION forming part of Letters Patent No. 539,458, dated May 21, 1895.
Application filed February 3, 1895. Serial No. 537,709- (No model.)
To all whom it may concern.-
Be it known that I, EMELL WARNER, a citizen of the United States, residing at St. Louis, in the State of Missouri,have invented certain new and useful Improvements in Smoke-ConsumingAttachments for Blast-Furnaces; and I do declare the following to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon,which form part a of this specification.
The object of my invention is to' provide means for consuming the smoke and gasesin a furnace employed for welding or forging metal. 7
My invention consists in the construction, arrangement and combination of parts, hereinafter set forth, pointed out in my claims, and illustrated by the accompanying drawings, in which- Figure 1 is a transverse sectional elevation on the line 1 1 of Fig. 2, showing my device attached to a furnace. Fig. 2 is a side elevation, partly in section, of a furnace embodying my invention.
In the construction shown the numeral 10 designates a fire box and 11 a heating furnace, separated by a bridge wall '12. Mounted in the bridge wall 12 and extending trans,- versely of the furnace is an air box 13, and an air pipe 14 communicates with oneend of said box 13 outside the furnace, through which pipe 14 air is forced under blast into and through said box. The air box 13 is extended outside the furnace and two pipes 15, 16, lead in opposite directions from the projecting end thereof opposite the pipe. let. The pipe 15 leads to the ash pit 17 beneath the grate 18, and the pipe 16 leads to one end of an air box 19 located in the roof of the fire box 10 and transversely of the furnace.
The air box 19 is located in advance of the bridge wall 12 and has aslot 20 in the bottom thereof, which slot affords communication between said air box 19 and the firebox, adjacent to the passage 21 above said bridge wall.
In the operation of this device the draft is forced by the blast through the pipe 15, and
the smoke and gases rise for passage through and above the bridge wall12 and are met by the blast of air from the slot 20, air box 19, and pipe 16, and commingling with said blast of air from an inflammable gas which is con sumed and destroyed in the fire box, thus saving fuel and destroying the major portion of the offensive smoke and gas.
By locating the air passages in metallic pipes and leading the same outside the furnace,I am enabled to minimize the cost of construction, and retain the temperature of the outer'surface of the pipes at amuch lower degree, thus avoiding the ordinary difficulties engenderedby the burning out of the pipes, and at the same time providing for repairs and displacement, when necessary, with much greater convenience.
What I claim is- 1. An attachment for blast furnaces, comprising an air box so shaped as to be located in a bridge wall and project outside the furnace at both ends, connection between one end of said air box and blast mechanism, pipes-15, 16 connected to the opposite end of said air box and extending in divergent planes therefrom, the pipe 15 leading to the ash .pit of the furnace, an air box 19 located in the roof of the furnace and communicating there with the full width of the fire box in a vertical plane adjacent to the bridge wall, and connection between the upper end of the pipe 16 and one end of said air box 19, as set forth.
2. In a furnace a bridge wall, an air box 13 mounted in said bridge wall and extending outside the furnace at both ends, a blast pipe connected to one end of said air box, and divergent pipes 15, 16, connected to the other end of said air box 13, the pipe 15 leading to the ash pit 17,'an air box 19 located in the roof of the fire box, and extending outside the furnace at one end and connected to the in presence of two witnesses.
