COKE-OVEN.

SPECIFICATION forming part of Letters Patent No. 471,033, dated March 15, 1892.

Application filed June 23, 1890. Serial No. 356,437. (No model.) Patented in England September 3, 1884, No. 11,967.

To all whom it mayconoern:

Be it known that I, RICHARD DE SOLDEN- HOFF, asubject of the Queen of Great Britain, residing at 71 St. Mary Street, Cardiff, in the county of Glamorgan, South Wales, have invented certain new and useful Improvements in Coke-Ovens for the Treatment of Coal in Order to Obtain Coke and By-Products Therefrom, (for which I have received Letters Patent in England, No. 11,967, dated September 3, 1884;) and I do hereby declare that the following is afull, 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.

The invention has for its object improvements in apparatus employed in the treatment of coal in order to obtain good furnacecoke and valuable by-products therefrom.

Apparatus constructed according to my invention is represented in the accompanying drawings, in which- Figure l,whioh is drawn in two parts and to a larger scale than Figs. 2 to 6, represents vertical sections drawn on the lines 1 1 and 2 2 of Fig. 3. Fig. 2 represents horizontal sections drawn on the lines 3 3 and 4 4 of Fig. 1. Fig. 3 represents avertical section drawn on the line 5 5 of Fig. 1. Fig. 4. represents a vertical section drawn on the line 6 6 of Fig. 1. Fig. 5 is an elevation, and Fig. 6 isaplan. Figs. 7 and 8 are respectively a cross-section and a horizontal section of parts drawn to a larger scale than Figs. 2 to 6. Figs. 9, 9, 10, and 11, drawn to the same scale as Fig. 1, are vertical and horizontal sections representing slight modifications.

In all the figures like parts are marked with similar letters of reference.

I will first describe the arrangement of apparatus represented at Figs. '1 to 8.

The coking-ovens, which are shown at 1 1, are of a rectangular shape, having suitable charging openings or hoppers Z, provided with lids Z. (See Figs. 3 and 6.) All of the ovens are provided on one of their sides and just by the spring of the arch with a number of openings Ct, which lead the gases generated in the oven to a conductingflue A, situated above the side walls of the ovens and running along the entire length of each oven.

and this is done in the hydraulic main. The

conducting-fines A connect with the collecting-flue E through a suitable opening or open ings b at one end of each conducting-flue A and which may be open or closed, according to the requirements of the process. This opening I) will be closed when the conductingflue A is put in connection with the condensing-plant and will be open when the gases are used to be burned and to heat the flues ofthe ovens. The openings 12 may be closed by means of any suitable lid or tile b (shown in dotted lines,) which may be inserted through the side openings 6 in the outer wall of the flue E.

The gases travel in the flues in the following manner: From the collecting-flue E, which runs the entire length of the series of ovens and which connects with all the side walls of a given number of ovens, the gases will flow through an opening'c, which may be provided with any suitable regulating means-such as the tiles or covers o-into a flue B, formed within the upperpart of each side wall and atterward into a flue 0, formed within the lower part of each side wall underneath the flue l3.

From the said lower fines 0 the gases will pass through flues m into flues Ct 04*, situated below the floor of each oven. Inthe first of said flues a the gases from the two adjacent side walls will meet and they will run together to the end of the said flue a, where by a short der the boiler directly up the chimney, as shown in Fig. 2.

To make the description complete I will describe the air-supply required for the combustion of gases in the fines B and 0, formed within the side walls. The cold air enters from the outside into a fine L, extending along the entire series of ovens. From this fine it will pass through openings Z, formed in the crown thereof, into fines H II 11*, situated below the fines immediately under each oven and arranged in sets of three each (see Fig. 2) and connected together in such a manner as to form one continuous fine. The cold air circulating successively in the fines II H H of each set will become heated, and when it arrives at the end of the third fine H of each set it will divide into two and will enter fines O, by which it will ascend into a fine D, formed in each side wall between the upper and lower gas-fines B G. The said fine D is so constructed that through its length it is perforated at top and bottom. The hot air consequently will spread into the upper and lower gas-fines B C and cause a perfect combustion of the gases circulating in the said gas-fines. Assuming now that the openings 1), leading the gases from the conducting-fines A to the collecting-fine E, are closed, the gases will then pass out of each conducting-fine A into a pipe M and from there into the hydraulic main N, constructed in a similar way to the hydraulic mains of gas-works. From the hydraulic main N the gases will pass through a pipe Q at one end thereof into the refrigerating-condenser P, which is composed of the following parts:

First, of a condensing-tube P, extending the entire length of the series of ovens, which is provided with a depressed or concave bottom forming a collecting-trough and in which the condensed tarry matters will accumulate, and whence by means of a pipe (not shown) they will be carried outside into a tank.

Second, of a revolving or stationary screw P, fixed inside the condensing-tube I, in order to lengthen the journey of the gases traveling in the condensing-tube I. The screw is composed of a wooden shaft 00 and of a spiral 00' of card-board or of other materialas, for instance, wood or iron or other material capable of resisting the tarry-matters. The screw is fixed in such a way in the con- (lensing-tube P that it can be taken out when required.

Third, of a tank R, in which the condensing-tube P is immersed and in which cold water constantly circulates. The gases leaving the condensing-tube P enter by passing through the tubes S S S into a series of scrubbers T T T (see Figs. 5 and 6,) similar to those used in gas-works for getting off the ammonia. After this the gases which are not The gases from the receiving-fine F, entering into the collecting-fine IE, will mix together and inflame, after which they will take the ordinary course of the gases in the fines, as described above.

In the modification represented in Fi 9 l dispense with the air-fines D and lead the air from the passages 0 direct into the upper gas fines B, where the gases inflame, and thence pass into the lower gas-fines (J, whence they pass into the fines a, and then pursue the course above described with respect to Figs. 1 to 8.

In the modification represented in Figs. 9, 10, and 11 I also dispense with the air-fines D, as above described, and I substitute for the lower horizontal gas-fines C a series of vertical fines 0, formed in the lower parts of the side walls. The inflamed gases pass from the fines B into the upper ends of the vertical fines C, and after traversing such fines they pass from the lower ends thereof into the fines a, whence they pursue the course above described with respect to Figs. 1 to 8.

Having now particularlydescribed and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is- 1. The combination,with the ovens and the collecting-fines A communicating therewith, of gas-fines formed in the side wall of said ovens and having communication with said fines A, the smoke-fine K, gas-fines a a arranged under the ovens and communicating with the aforesaid gas-fines and with said smoke-fine, an air-inlet fine L, and the connected fines II II H forming one continuous fine, having connection at one end with said fine L and at the other with the gas-fines in the side walls of the ovens and being arranged under the fines a a substantially as set forth.

2. The combination, with the ovens and the collecting-fines A connected therewith, of the connected gas-fines a (1 arranged under the ovens, the upper gasfiues 13, having connection with said collecting-fines, the lower gas-fines 0, connected at one end with fines B and at the other with fines a a, said fines B 0 being arranged in the side walls of the ovens, the air-warming fines II II 11*, arranged below the flues a a a and connected together, so as to form one continuous fine, the air-flue L, connected to one end of said continuous fine, the tines 0, connecting the other end of said continuous fine with the fine B, and the smoke-fine K,connected to the fines a a substantially as set forth.

3. The combination of a series of cokingovens, a hydraulic main, a condenser and scrubber, fines and pipes communicating bctween said ovens, hydraulic main, condenser, and scrubber, a collecting-flue communicating with the said ovens, gas-infiaming fines in the side walls between the ovens, connected with said collecting-flue, gas-fines a. a under the ovens, connected with the gas-infiaming fines, a main fiue leading to the chimney or IIO boiler and communicating with said fiues a a a cold-air-inlet flue, and air-warming flues under the fines a a communicating with said cold-air-inlet fiues and with the gas-fines in the side walls, substantially as shown, and for the purpose set forth.

I 4:. The combination of a series of cokingovens and condenser and scrubber, a collecting-flue having communication with said ovens and said scrubber, gas-inflaming flues in the side walls between the ovens, connected with said collecting-flue, gas-fines a a under the ovens, having communication with said gas-inflaming flues, a main flue leading to a' chimney or boiler and communicating with said flues a a an air-inlet flue, air-warming fiues under the fiues a, a communicating with said air-inlet flue, and air heating and distributing flues D in the side walls of the ovens, communicating with said air-warming fiues and with the gas-fines in the side walls, substantially as shown, and for the purpose set forth.
