GOKING-FURNACE SPECIFICATION forming part of Letters Fatent No. 668,402, dated February 19, 1901.
Application filed August 31, 1900. Serial No. 28,645. (No model.)
To ctZZ whonz it may concern:
Be it known that I, PORT B. ELKINS, a citizen of the United States, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented or discovered certain new and usefullmprovements in Coking-Furnaces, of which improvements the following is a specification.
The invention described herein relates to certain improvements in coking-furnaces of the class orkind consisting of a coking-chamber having fines in its side walls for the passage of products of combustion, &c., whereby such walls are highly heated for the purpose of driving off the volatile constituents of the coal. The side walls of this style of furnaces are constructed with two series of comparatively narrow flues connected at their upper ends by a horizontal flue, so that the products of combustion pass up one series of fines and down the other, heating the walls in their passage. In order to render the flue-walls sufficiently stable without unduly increasing the thickness of the walls, specially-formed brick must be used.
The object of the present invention is to construct the walls of the furnace so as to provide a double series of fines, thereby greatly increasing the heat-storing capacity thereof, and also to provide for the employment of commercial sizes of brick in the construction of such walls.
The invention is hereinafter more fully described and claimed.
In the accompanying drawings, forming a part of this specification, Figure 1 is a sectional elevation of a portion of my improved furnace, the plane of section being indicated by the line I I, Fig. 2. Fig. 2 is a vertical longitudinal section on a plane indicated by the line II II, Fig. 5. Figs. 3, 4, 5, and 6 are horizontal sections on planes indicated, respectively, by the lines III III, IV IV, V V, and VI VI, Fig. 1.
In the practice of my invention a series of longitudinal walls 1 and 1 and transverse walls 2 are built on the regenerating-chambers, forming air and combustion chambers 3 3 andd i, as is the usual practice. These chambers are closed on top by arches and skewbacks 5 and 6, as clearly shown in Fig.
1. On the skewbacks 5 are built the walls, suitably spaced to form between the adjacent walls coking-chambers A. Each of the walls is so built as to form two series of flues 7 7, extending vertically up through the walls and have their upper ends connected to the horizon tal iiues 8 and 8. At their lower ends the vertical fines are connected to the combustionchambers 4 l by ports or openings 9 9, cut
through the skewbacks, as clearly shown in Fig. 1. The transverse walls 2, Figs. 2 and 6, are arranged about midway of the length of the furnace, so that the several combustion and air chambers will be of approximately the same size. The air- chambers 3 and 3" are connected with the regenerating chambers (indicated by dotted lines in Fig. 6) by ports 10 10 preferably located near the outer ends of the air-chambers, which are connected with the combustion-chambers by ports 11 and 11, Figs. 1 and 2, formed through the walls 1 and preferably near the bottoms thereof. These ports 11 and 11 gradually increase in area in proportion to their distance from the ports 10 10, so that equal volumes of air enter the combustion-chamber through the several ports. Gas is introduced into the combustion-chamber through the pipes 12 12, arranged to discharge the gas below the level of the air ports or inlets 11 11.
In operating the furnace the heat and products of combustion pass from chambers l up through half of the series of fines 7 7, to the horizontal flues 8 8*, to the other fines 7 7*, down which they pass to the combustionchambers at, and thence through ports 11*, chamber 3, and ports 10 to the regenerating-chambers and the stack. When the valves ldand 17, controlling the flow of gas, air, and products of combustion,are reversed, the flow of heat and products of combustion will also be reversed. In passing through the fines 7 7 and the horizontal fines not only the exterior walls a are highly heated, but also the interior partition-walls b and c receive an equal amount of heat, forming what may be 'termed a heat reservoir greater in capacity than the exterior walls from which heat is drawn to supply that imparted to the coal in the coking-chambers A. This storage of heat is of especial advantage when the coal is charged into the chambers, as it prevents such a great reduction of heat as occurs in the present construction of furnace having single flue-walls.
It is characteristic of this construction that the outer walls and partitions can be made from commercial sizes of brick, such as nine and six inch brick, the former being used in all cases except alternately for the transverse portions-as, for example, in one transverse partition the nine-inch bricks extend from between the ends of bricks forming the outer walls to the face of the longitudinal partition I); but in the adjacent transverse partitions two six-inch bricks extend from the inner faces of the outer walls to a plane midway between adjacent bricks in the longitudinal partition. In the next course a nine-inch brick will be superposed on the six-inch and the six-inch on a nine-inch brick. This construction firmly ties the outer walls to the longitudinal partitions. The horizontal flues 8 and 8 are covered by skewbacks 13, which have their under sides recessed, as shown in Fig. 1, for the reception of the upper edges of the partition I) and outer walls a.
The coking-chamber is provided with outlet-pipes 14 for the escape of gas and with openings 15, through which fresh fuel is charged into the coking-chamber.
I claim herein as my invention A coking-furnace of heating-walls suitably spaced with reference to the formation of coking chambers between adjacent walls, each wall for its entire length or approximately so being provided with two series of Vertical dues and with two horizontal flues each connected with the upper ends of one series of vertical fines, and two combustionchambers each connected to the lower ends ofone-half, more or less, of both series of vertical flues, substantially as set forth.
In testimony whereof I have hereunto set my hand.
