METALLURGICAL FURNACE.
SPECIFICATION forming part of Letters Patent No. 228,944, dated June 15, 1880. Application filed November 11, 1879.
To all whom it may concern:
Be it known that I, ELLIOT SAVAGE, of West Meriden, in the county of New Haven and State of Connecticut, have invented a new and useful Improvement in Metallurgical Furnaces, of which the following is a specification.
The object of this invention is a metallurgical furnace in which the combustion of thefuel can be perfectly controlled, so that the nature or character of the flame admitted to the heating-chamber may be made, as desired, either a reducing-flame or an oxidizing-flame, according as the duty to be performed in the heating-chamber requires one or the other.
The invention consists in a peculiar arrangement of a coking, a fuel, and a heating chamber, and a flue or flues uniting said fuel and heating chambers, combined with one or more air-passages which are controlled by suitable valves, by which the supply of air to the fuelchamber and to the gases passing from the fuel to the heating chamber may be perfectly controlled.
It further consists in an arrangement of B is the coking-chamber, having an inclined dead-plate, upon which the fuel is thrown. This is shown located above the grate in front of the furnace; but it may, if desired, be located upon either side of the fuel-chan'iber C, or one upon each side.
D is a flue leading from the fuel-chamber C to the heating-chamber E.
F F are flues which pass down at the rear corners of the heating-chamber and return upon each side below the heating-chamber. Through these flues the gases pass from the heating-chamber to the second combustionchamber, G.
H H are flues leading from the second combustion-chamber around flue D and into the uptake I. i
J is an air-passage opening into a narrow chamber, K, in the rear wall of the fuel-chamber, and L is an air-passage in rear of the ash-pit M. l l l are perforations passing from this passage to the ash-pit, for the purpose of admitting air to the fuel through grate-bars N, and O is the air-passage to admit air to the secflues through which the gases which pass from ond combustion-chamber through the narrow 7 5 the heating-chamber are returned to a second chamber P. The air-passages are each fitted combustion-chamber, which chamber is located with a valve or wind-gate, Q, and a short pipe, beneath the flue which conveys the gases from R, to connect with the pipe of a fan or blower. the fuel-chamber and adjacent to the passage S is the door of the coking-chamber, and which admits air to said gases. The flues from T the door of the heating-chamber. the second combustion-chamber; pass around Inspection-openings are provided in the the flue that conveys the gases to the heatingwalls of the chamber, through which the operchamber, so that the heat produced from the ator may observe the flame and determine the perfect combustion of the gases in the second amount of atmospheric oxygen to be admitted combustion-chamber is utilized to heat the air to produce the required flame in the heating supplied to the gaseous fuel entering the hea'tor smelting chamber, which will, of course, ing-chamber as Well as the gases with which depend upon the character of work required it combines. of the furnace.
- In the accompanying drawings, in which The character of the flame, as well as its inlike letters of reference indicate identical tensity, is regulated or changed at will by 0 parts in the various figures, Figure l is a cenulating the supply of atmospheric oxygen tral longitudinal vertical section of a furnace admitted through the ports J and L l l L. If embodying my improvements. Fig. 2 is a an oxidizing-flame is required in the heatingtransverse vertical section taken through line chamber, a sufficient quantity of oxygen is a a of Fig. 1. Fig. 3 is a horizontal sectional supplied, through port J, to the gaseous fuel 9 5 plan view taken in line b b of Fig. 1. Fig. 4 and carbonic oxide passing from the fire-box to is a similar View taken in line 0 c; and Fig. 5 flue D to unite with the carbon in the gases is a plan taken in section on line (I d of Fig. 1. The walls or mason-work of the furnace are represented by letter A.
and produce carbonic acid.
The intensity of the flame may be regulated with perfect exactness. If but a moderate IOO heat is required, less air is admitted through the ports J andL; if an intense heat is required, a full blast is introduced through these ports; if a reducing or carbonizin g flame is required, the supply of air admitted through port J is limited until the proper effect is produced. I am thus enabled to produce the various grades of iron or steel from the same ore.
The gases, after passing from the heating or smelting chamber E to the second combustion-chamber, G, through flues F, receive sufficient air through port 0 to combine with any carbon remaining in the gases, thus producing perfect combustion and utilizing the heat thus generated to heat Walls of flue D and the walls of the air-chambers K P.
The changes of form necessary to adapt my furnace to the various requirements of smeltin g, heating, annealing, or forging will be readily understood by those skilled in the art, and need no description here.
Having thus described my invention, I claim- 1. In a metallurgical furnace, the combination of the chambers B, O, and E with flue D and an air-port controlled by a valve for the admission of air to the gases at the junction of said chamber 0 and flue D, for the purpose specified.
2. In a metallurgical furnace, the combination of the chambers B, O, and E with flue D, port J, to admit air to the gases at the junction of chamber 0 and flue D, and port L, to admit air under the grate, said ports J and L having valves Q, substantially as specifled.
3. The combination, substantially as specified, of the chambers B, O, E, and G, flues D and F, with the air-passages J, L, and O, and their controlling-valves Q.
4. In a metallurgical furnace, the combination, substantially as specified, of flue D, chamber Gr, flues H H, and air-chambers K and P, said flues H H passing upon the sides of flue D, and said chamber Gr being in close proximity to chambers K and P, for the purpose specified.
ELLIOT SAVAGE.
