APPARATUS FOR THE MANUFACTURE OF COKE.

SPECIFICATION forming part of Letters Patent No. 409,567, dated August 20, 18879. Application filed October 2l, 1887. Serial No. 253,025. (No model.) Patented in England May 23,1887,No. 7,482.

T all whom it may concern:

Be it known that I, RICHARD DE SOLDEN-` HOFF, engineer, a subject of the Queen of Great Britain, residing at 7l St. Mary Street,

Cardiff, in the county of Gla1norgan,England,

have invented certain new and useful Improvements in or Additions to Means or Ap-` paratus Employed in the Manufacture of Coke for the Desiccation and Incineration 1o of Precipitants or Solids Resulting from Sludge or other Substances Liable to Putrefy,` (for which I have received Letters Patent in Great Britain, No.v r7,482, dated May 23, 1837,)-

cess is conducted in connection with the manufacture of coke with coking-eoals.

Instead of locating the incineratingfurz5 naces above the coke-ovens, as heretofore, I, according to my present invention, locate such incineratin g-f u rnaces between two cokeovens, and I locate above each of such incinerating-furnaces a hopper or chamber, in 3o which the sludge or other material under treatment is iirst received from the truck orA other conveyer, and isf there dried previousto being passed into the incinerating-fur` nace.

My present invention is represented in the accompanying drawings, in which- Figure l represents vertical sections on the lines A B C D E F G of Fig. 3, and J K L of Fig. 2, and a partial front elevation. Fig. 2 4o is a cross-section on the line C D of Fig. 4. Fig. 3 is across-section on the line E F G II of Fig. 4; and Fig. 4 represents a horizontal section on the line M N O P Q R S T of Fig. l, a sectional plan of a pair of incinerating furnaces, horizontal sections on the lines U WV of Fig. 3, X. Y Z of Fig. 2, and A B of Fig. 3, and a partial plan of a block of incinerating-furnaces and coke-ovens.

In carrying my present invention into ef- 5o feet, I prefer to employ the arrangement and combination of parts represented in the drawings; but I do not coniine myself to the preoise arrangement of fines and passages nor to the directions taken in the circulation of the gases and superheated air.

In arranging any number of incineratingfurnaces, I locate each of such furnaces between a pair of coke-ovens, with the exception of the first and the last of such incinerating-furnaces, on the outer side of each of which I place two coke-ovens. If desired,`how ever, two cokeovens may also be interposed between the incinerating chambers. Any desired number of incinerating furnaces, combined with coke ovens, as above described, may compose a block; but the number of such furnaces and ovens represented in the drawings to a single block is that which Iv prefer. Each block is provided with a chimney, (not shown.) into which the main iiue c leads, and each block may, if desired, be provided with a condenser communicating with the pipe b. rlhe direction taken in the circulation of the gases is represented by t-he arrows. (Shown in full lines and numbered in such a way that the lowest number indicates the starting-point for the gas, and the highest number indicates the point where the gas reaches the main ne.)

The arrows shown by the dotted lines represent the direction of circulation of the superheated air.

In order to facilitate my description of the construction of the incinerating-furnaces and coke-ovens, together with their mode of working, I will describe two coke-ovens c o and one ineineratingfurnace d. I will assume that the two coke-ovens c c have been charged with coal for some few hours, and that the gases generated in them areinamed and escapethrou gli openings c2. There are eighteen of these openings shown on each side of the ovens, but other suitable numbers of such openingsmay be employed. These openings c2 are situated just at the spring of the arches or crowns of the cokeovens. rlhe gases escaping from the coke ovens through these openings c2 at first circulate in the side walls situated between the furnace d and the coke-ovens c c in the manner represented by the sectional view Fig. 3. The gases leave these two said side walls through the openings e e', and by such openings enter the incinerating-furnace d, as represented by the sectional view shown at IOO Fig. 2. I assume that the furnace d is already charged with sludge-cake or other material to be treated, and that the gases entering such material to be incinerated, while the lowest parts f the incinerating-furnace-that is to say, those parts next the doors fZ-will con tain l almostcompletelyincinerated material. The

gases entering the furnace CZ are very hot, and

the entrances being next the doors, the hottest I gases meet with the sludge-cake or other material in the most advanced stage of incineration. The gases leave the furnace CZ through vthe openingsff, whence they are directed into the iiues h h', situated under the door of the furnace d. Each part of the floor is provided with two iiues 7L h underneath the same. The gases leaving the two iiues h are directed immediately into the fiues situated under the ovens c c', while the gases leaving the two iiues h pass first into the iiuej, and from thence into the iiues of the vtwo ovens c c.:

(See Fig. 2 and sections C D E and F G, Fig. l.) The gases having performed their work then pass away from the flues under the ovens c c into the main iiue a. The cold air enters by the end opening of the iiue 7o, which is parallel to the main iiue a. The air in traversing 4the iiue lc becomes warm, and thence passes into the flue Z, which is also parallel to the main flue a, but on the other side of it. The air becomes hot in the flue l, and in that condition reaches the two horizontal iiues m m', situated just above the incinerating-furnace d through the vertical flue m2. The flues 'm and m are provided with iiues qq, which communicate by openings p Orp with the furnaces (Z. They are also in connection with iiues n n', connecting them with the side walls of each coke-oven, and are provided with openings o o', connecting them with the coke-ovens. (See Figs. 2 and 3 and section AB of Fig. 4t.)

The incinerating-furnaces and the cokeovens are worked in the following manner: The coke-ovens are iirst charged, and when the coking process is in full operation, but

.y not till then, the incinerating-furnaces are to be charged. The sludge-cake from the presses lthe furnaces on a or other material to be treated is brought to platform-truck s, (see Fig. 1,) provided with a hole s in the middle of its platform. Vhen the truck s is over the hopper r, the door r of the latter is opened, and the sludge-cake or other material in the truck s is pushed into the hopper fr, and when the said hopper is fully charged the door r is closed. The sludge-cake or other. material so Vcharged into the hopper r' ina few hours becomes nearly dry at the lower part. The opening in the bottom of the hopper r, which communicates with the incinerating-furnace d, may be closed by an arrangement of cup and cone or other suitable valve or door, or by an arrangement of vtwo, rabbles tt', as shown at Fig. 2. When the lowest part of the sludgecake or other material in the hopper r is dry, a slight motion of one 0f the rabbles at a time will deliver 'some of such material into the incinerating-furnace, and by means of the same rabbles t-he sludge-cake or other material so delivered to the incinerating-furnace may be pushed farther down the floor of the said furnace CZ. The capacity of the hopper r is preferably equal to that required for the charge for the incinerating-furnace. The hopper r is also provided with an opening r2, communicating with the main pipe b by means of a short pipe u, so that all the steam and vapors generated during the process of drying the sludge-cake or other material contained in the hopper r will pass into the main pipe b and thence into the condenser, if such is used, or into the chimney. As soon as some of the sludge-cake or other materialis charged into the incinerating-furnace cl some new sludge-cake or other material is charged into the hopper r in order to keep it always full. The incinerating-furnace d is also to be kept fully charged, and this is easily done by pushing the charge, with one of the rabbles t or t', down the iioor of the furnace d. The sludgecake or other material having passed from the highest point of the furnace CZ to its lowest point-that is to say, down to the doorgets reduced toV ash. At this time the door CZ is to be opened and the-ash dropped into a tram-car or hopper, or onto a revolving tablc, or onto a transporter or elevator, by which it may be ultimately delivered to the stores. The gases circulating in the furnaces, as described above, inflame the dry sludge-cake or other material, and the combined heat of the gases from the coke-ovens and of those from the sludge-cake or other material being treated makes the incineration proceed very rapidly.

The incineration proceeds all the more quickly on account of the hot air being constantly supplied to the incinerating-furnaces.

In addition to the rapidity of incineration which is obtained-by the introduction of gases from the coke-ovens into the furnaces d, another advantage is obtained, namely, the perfeet combustion of some of the gases, some of the greasy and heavy gases given off from the sludge-cake or other material possessing very nasty and disagreeable smell. The coke-ovens are charged through two openings cS situated on their top. The coal is brought to them by small tram-cars, carried on the platform-truck s, and provided, as already stated, with a hole s in the middle of the platform. The tramcars are emptied through said hole s into the ovens c c. The coals are leveled in the IIO ovens in the usual manner. The ovens are then closed and the coking process takes place in the usual way. The arrangement of the ovens and furnaces is such that the ash is delivered onto a lower level than the coke-bank in such manner that the manufacture of the ash does not interfere with the manufacture of coke.

The arrangement of incinerating-furnaces may be used with other constructions and arrangements of coke-ovens.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be per-V formed, I decla're that what I claim is l. The combination, with two or more cokeovens and flues under said ovens, of an in cinera-ting furnace situated between said ovens and consisting of two inclined chambers communicating at their upperends, iiues connecting the upper port-ions of said ovens with the lower ends of said inclined chambers, and fiues under said inclined chambers connected with the upper ends thereof and with the flues under the ovens, substantially as set forth.

2. The combination, with two or more cokeovens, iiues under said ovens, the main flue a connected with said fines under the ovens, and a hopper, of an incinerating-furnace, having its oor inclined downwardly from its midlengt-h, interposed between said coke-ovens under said hopper, iiues leading from said ovens to the furnace at the lower ends of said inclined floors, and flues under said furnace connected therewith and with the flues under the ovens, substantially as set forth.

3. The combination, with two or more cokeovens, of an incinerati11g-furnace interposed between said ovens and connected therewith, and having its floor inclined downwardly from its mid-length, a hopper arranged above the upper ends of such inclines, the doors d',
