Description
UNITED STATES PATENT OFFICE.
HUGH FERGUSON, OF PITTSBURG, PENNSYLVANIA.
REG ENERATlV-E HEATING-FURNACE.
SPECIFICATION forming part of Letters Patent No. 349,306, dated September 21, 1886.
Application filed February 5, 1386. Serial No. 190,955. (No model.) I
To all whom it may concern:
Beitknow'n that I, HUGH FERGUSON, a citizen of the United States, residing at Pittsburg, in the county of Allegheny and State of Penusylvania, have invented certain new and useful Improvements in Regenerative Heating Furnaces; and I do hereby 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 pertains to make and use the same, reference being bad to the accompanying drawings, which form a part of this specification.
My invention relates to an improvement in continuous regenerative heating-furnaces, the object being to provide a furnace that will supply a continuous current of highly-heated air to the combustion-chamber without changing the direction of the same; and with this end in viewmy invention consists in certain details of construction and combination of parts, as will be more fully explained hereinafter.
In the accompanying drawings, Figure 1 is a sectional elevation of my improved furnace on the line 1) w or z 2, Figs. 2 and3. Fig. 2 is a sectional plan view of the same on the line 00 3 Fig. 1. Fig. 3 is a sectional end elevation near the center of the furnace.
To put my invention into practice I construct in the base of the furnace a number of parallel flues, a b, separated the one from the other by narrow partition-walls c, for conducting air to the combustion-chamber (l and the waste products to the draft-stack 6. On the top of these flues a b, I arrange several others, f, running in a transverse direction, one of which is in communication with the outside by a short passage, o. On the top of these flues f is placed a metallic plate, 9, provided at each end with an open-ended box, h, through which the air is allowed to circulate and cool the bridge-wallsi 7'.' This plate g also supports the workingchamber is above. The
air-flues f are in communication with part of those below b by means of a short passage, Z, and the same flues b are provided with openings onto the combustion-chamber (1 above. The alternate flues a for the waste products of combustion at the base of the furnace lead from the chamber nto a large chamber or fine, p,.Wl1iCl1 is joined to the draft-stack e. The workingchamber k is provided with a door, q, for the proper working of the same. A number of buck-staves and tie-bolts are arranged on the outside of the furnace after the manner usual in furnaces of this kind. The arched wall oserves to bind the fines a, b, and f when expanding or contracting in different degrees of heat.
The gas-pipe s and nozzles 25, entering the combustion chamber (1, supply the furnace with fuel.
The operation of my improved furnace is as follows: The gas escaping from the nozzle 15 and brought in contact with highly-heated air from the flues below ignites, and burning over the working-chamber k enters the chamber 11, and traveling th roughthe flues c imparts heat to the walls of the same and enters the draftstack e. The air passing through the fiuesf b collects the heat from the surface of the different partition-walls c, and from the bottom of the working-chamber it enters the passage or to the combustion-chamber d, and mingles with the gas from the nozzles t, thus having a continuous passage, and not requiring any change of passageor direction.
I am aware that it is not new i'n regenerative and other furnaces to employ gas-flame in combination with highlyheated air, the gas and air being combined at a point in close re lation to the working-chambers of the furnace. I am also aware that in a broad sense it is not new to convey cold air into a fine and conduct it through heating-flues between flues through which the products of combustion are conducted on their way from the combustionchamber to the chimney or uptake. I do not therefore claim such features as my invention.
Having thus described my invention, what I claim, and desire to secure by'Letters Patent,
In a furnace of the character described, the combination of horizontal parallel flues a I), located in the base of the furnace and separated by narrow walls, the transverse fines f, com- 'municating with the external air at one end,
1;, and with flues b at the opposite end by vertical passages Z, the superimposed metal plate having 0pen-end boxes at its extremities embedded in the bridge-wa11s i j, the workingehamber k, the gas-supply pipe and nozzles, and the combustion-space communicating at one end with the h0t-air fiues b by the passages an, and at the opposite end with the fines a by the chamber a, having an arched front wall, 0, and the draft-stack c, communicating with the fines (I by the transverse flue p,ai1c0nstrueted and arranged substantially in the manner and I0 I for the purposes described.
' HUGH FERGUSON.
