METALLURGICAL FURNACE.
SPECIFICATION forming part of Letters Patent No. 310,454, dated January 6, 1885.
Application filed July 18, 1884. (No model.)
To all whom it may concern.-
Be it known that I, WILLIAM MOKENNA, of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Metallurgical Furnaces; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, in which- Figure 1 is a front elevation; Fig. 2, a vertical longitudinal section; Fig. 3, an end elevation, and Fig. 4 a view of the gas-burner.
My invention has relation to the construction of metallurgical furnaces of such classes as are adapted for the puddling, heating, or refining of iron or steel, and for other similar purposes, and has for its immediate object the utilization in such furnaces of natural gas to the best advantage and the simplification of construction.
My invention consists in the arrangement and combination of parts, hereinafter fully described and claimed.
In the drawings, A designates the working or melting chamber, b b the boshes, O the neck, D the stack, and E the hearth, of the puddling-furnace, all arranged and supported in the ordinary manner.
Under the hearth-plates E, I form a chamber, F, by suitably supporting the brick, tile, or other partition ghorizontally, resting at the combustion end of the furnace on the wall h, as shown, and leaving at the other end a flue or communication, 6, between the chamber F and the space K underneath.
L is the end wall of the furnace. An inletflue, m, is arranged suitably, so as to admit air to the space K, as shown. Between the wall L and the wall h, which stands across the entire width of furnace, I erect a diaphragm or partition-wall, n, as shown, thus forming the air-flue f and mixing-chamber q, and form one or more ports, 1), near the bottom of said wall, which ports then serve to admit the heated air to the mixing-chamber q, formed between walls L and a. From the top of wall a, I erect an inclined breast or deflector, s, rising to the top of the front bosh of working-chamher A.
When. the furnace is in operation, the draft draws in air at the inlet m, which air passes into the space K, taking up waste heat as it gbes, then rises at z, and passes along the chamber F, getting more highly heated as it passes along, and thence by flue f to port or ports 9, and finally to mixing-chamber q, all as indicated by arrows in Fig. 2. From the outside, at the fire end, I insert a gas-pipe, 1!, bearing a cross-pipe, c, perforated for the passage of the gas in fine jets into the mixingchamber q. The cross-pipe c, or burner, is placed on a line below that of port or ports 12, so that, driving out under pressure, it sinks the heated air as the latter emerges from ports 12 into chamber q, and effects a most thorough mingling therewith.
By means of a suit-able damper or valve to control the air and gas, a mixture can be effected which will produce perfect combustion or otherwise, so that the flame striking the contents of hearth E may be of any desired character, oxidizing, reducing, or simply heating in its function. The heat derived from this construction is very intense and quickly developed, while the expenditure of gas is minimum.
The construction is simple and cheap and does away with the expensive hanging arch ordinarily formed in front of the bridge-wall, while the substitution of the inclined breast s for the usual bridge-wall prolongs the life of the furnace.
Having described my invention, I claim- In a metallurgic furnace adapted to burn gas as a fuel, the combination, with the working-chamber A, the horizontal flue K, entering at the bottom of the furnace, the returnfiue F, passing between the fiueK and the chamber A, of the depending flue f, the dividing-wall it, having an opening, 1), located entirely below the top of fiue K and leading to the ascending fiue g, which has an unobstructed passage directly to the working-chamber, and a gas-burner at its bottom and below the opening 12, substantially as described.
In testimony that I claim the foregoing as my own I have affiXed my signature in the presence of two witnesses.
