SPECIFICATION forming part of Letters Patent No. 794,662, dated July 11, 1905.

Application filed January 20, 1903. Serial No. 139,848.

T0 a/ZZ whom, t may concern:

Be it known that l, EvENoE COPPE, a subject of the King of Belgium, and a resident of 71 Boulevard dAnderlecht, Brussels, Belgium, have invented certain new and useful Improvements in Coke-Ovens, of which the following is a specification.

This invention relates to improvements in the arrangement of coke-ovens described in the United States Patent No. 654,307 of September 23, 1899, having for their object a better distribution of the points of introduction of gas and air to insure still greater uniformity of temperature throughout the length of the ovens and to achieve a more perfect regulation of the gas and air introduced both at the front and the back of the oven. These improvements are effected by the following characteristic arrangements:

First. Identical construction of the half of the wall in front and of the rear half, the partition compelling the gases to follow identical courses both at the front and at the rear of the oven, the circulation of the gases under the lioor, being according to the circumstances, as follows: Half under the front part and half under the back part of the floor, each half subsequently entering separately a collecting-liuc, whence they pass to the chimney, when the oven has two such collectingiiues, or invariable and adjustable proportions, according to the necessities of the mode of working, when the oven has a single collecting-ilue and is arranged for the return of the gas or for its subdivision under the floor.

Second. The arrangement in the front and the rear of the oven at the lower part of the wall of a canal for introducing a mixture of gas and air, which is brought without loss of heat to the part of the flues of the wall where it should burn, in combination with air-inlets in the foundations of the oven, bringing to the said part the air necessary for complete combustion.

Third. Special arrangements for working the oven with recovery of by-products, whereby the gas and air introduced under the walls of the ovens are mixed in variable proportions, as may be desired to prevent formation of gas-carbon near the ports and to insure complete combustion and a uniform and regular temperature throughout the length of the oven.

Fourth. Pipes or ducts formed in the foundations of the ovens and accessible by vaults in these foundations for cleaning the distributing-ports for the mixture of gas and air in the combustion-chamber.

In the accompanying drawings three forms of ovens constructed according to this invention are shown.

Figures 1 to 4 represent the first form, which is characterized by having two collecting-channels. Figs. 5 to 9 represent the second form, which has only one collectingchannel and is arranged for the return of the gas. Figs. 10 to 13 represent the third form, characterized by arrangements for subdividing the gases beneath the floor, combined with a single collecting-channel.

Fig. 1 is a longitudinal section through the coking-chamber. Fig. 2 is alongitudinal section throu h the wall. Fig. 3 is a transverse section on ine A B C D of Fig. 1. Fig. 4 is a horizontal section on line E F of Figs. 1 and 2. Fig. 5 is a horizontal section across the coking-chamber of the second form. Fig. 6 is a longitudinal section across the wall. Fig. 7 is a transverse section on line G H of Fig. 5. Fig. 8 is a transverse section on lines l K L M of Figs. 5 and 6, and Fig. 9 is a horizon- 'tal section on line N O of Figs. 5 and 6. Fig. 10 is a longitudinal section across the cokingchamber of the third form. Fig. 11 is a longitudinal section across the wall. Fig. 12 is a transverse section on line P Q of Fig. 10, and Fig. 13 is a horizontal section on line R S of Fig. 12. As in the earlier arrangements, the present ones are arranged for working Without recovery of by-products as well as for working with recovery.

Working 'without recovery of 19g-products.- Referring to Figs. 1 to 4, the dampers y are closed, as shown in dotted lines in Fig. 2. The gas evolved from the coal passes in the upper part of the oven through the four openings o, the valves in which (shown in the drawings) are in this case raised. The gases thus enter the chambers p, whence they pass into the wall by the four chambers p, and

IOO

then passing through the openings Z, descend into the partition by eighteen iues i, of which nine are in front and nine behind. rl`he gases thus arrive in the chambers f to ascend eight iiues t', four of which are in front and four behind. The two currents of gas thus reunited then descend by six fiues y' and pass beneath the floor, where they depart by flues g in the front half and by flues in the rear half to the collecting-channels l X, which are connected to the chimney. Where the oven has only one collecting-channel, with a return-passage r for the gas, Figs. 5 to 9, the progress of the gas is the same as in the previous case up to the point where it descends by the six flues lt then passes under the Hoor, where it meets the gas from the neighboring oven, to be turned in proportions suitable for the Inode of working, one part directly to the iiue g of the oven, the other part toward the front of the oven, to pass under the floor of the neighboring oven, through the gas-return passage r, and thence through the flue g to the collecting-channel and to the chimney. This arrangement, by which the ovens communicate in pairs underneath the floor, there being provided a gas-return passage r, allows regulation of the draft before and behind the oven in the flues.

In the third modification, having the subdivision under the floor and shown in Figs. 10 to 13, the progress of the gas is just the same up to the point where it descends through the six iiues Having arrived under the floor, the gases divide according to the necessities of the working, one part going directly through the flue g to the collectingchannel X and to theV chimney, the other part Y assing toward the front of the oven to be delivered into the other half of the floor, whence they reach the collecting-channel X, and consequently the chimney, by way of the flue g. It is obvious that in this case, as in the preceding one, the subdivision of the gas beneath the fioor is regulated by appropriately adjusting the dampers, the more or less complete closing of the dampers of the ilues Q forcing the gas to take its course toward the front and to pass by a less direct but longer passage to the flues g/ and the collectingchannel.

W arising with recovery of 12g-products.- The dampers y are raised, as shown in full lines in Figs. 2, 6, and 11, and a valve is closed in each of the two ports o in front and the rear parts of the ovens, as is shown in Figs. 1, 5, and 10. These dampers prevent the gas from the ovens passing into the flues of the wall. The draft causes the gases to pass into the pipes h and u, arranged above the ovens, and are conducted therethrough to condensers. From these condensers they return to the special ducts a, Figs. 2, 6, and 11, to which are attached brano es I), leading to mixing apparatus, such as injectors c, which mix the gases with a certain proportion of air. The mixture thus introduced into the flues d rises into the flues or combustion-chambersf, arranged under the wall, by way of the ports e beneath the said chambers The air necessary for complete combustion enters by the ducts g in the foundations of the ovens and passes into the combustion-chambers where it meets the mixture of gas and air arriving by the flues d. From the combustion-chambers f the gases rise through twenty-six flues i i-thirteen in the front and thirteen in the rear-and then descend again through the six flues and pass beneath the floor to the collectingchannel X and to the chimney, as was described for working without recovery of byproducts in the three modifications.

Comparison of the construction just described with that formerly used shows, first, in the new arrangement the wall comprises thirty-two vertical flues instead of twentytwo; second, the two ports for the passage of gas arranged in the old form near the middle of the arch are here suppressed; third, the arrangement in the present construction of the flues d for the mixture of gas and air both in the front and in the rear of the ovens, (see Figs. 2, 3, 6, 7, 8, 11, 12;) fourth, the arrangement of two collecting channels X, Figs. 1 and 2; fifth, the arrangement of gasreturn passage 1, Figs. 5, 6, 8, and 9; sixth, the arrangement by which the gas-current is subdivided under the iioor throughout the length of the oven, Figs. 12 and 13 5 seventh, the arrangement of ducts g for admitting air f in the foundations of the ovens, Figs. 1, 2, 5, 6, 8, 10, and -11; eighth, special arrangements c for mixing the gas and air, Figs. 2, 6, and 11; ninth, the arrangement of pipes or ducts :ic in the foundations of the oven and accessible by vaults in the foundations to allow the ports c for distribution of the mixture of gas and air to be cleaned, Figs. 2, 6, 8, and 11.

Having thus described the nature of this invention and the best means l know of carrying the same into practical effect, l claim- 1. ln combination with a series of horizontal externally-heated coke-ovens, which can be worked with or without recovery of byproducts, and having walls constructed similarly in the front and rear of the ovens, gasreturn passages r r beneath the ovens distributing the mixture of gas and airarriving from the walls of two contiguous ovens, in variable and adjustable proportions according to the necessities of the working, one part under the iioor of one of said ovens and the other part under the floor of the neighboring oven, substantially as described.

2. ln combination with a series of horizontal externally-heated coke-ovens which can be worked with or without recovery of byproducts, and having walls constructedsimilarly in the front andv rear of the ovens, a

5 riving under the floor are distributed according to the necessities of the Working, into both parts of the floor, one part passing toward the front and the other part going directly toward the rear, substantially as de- 1o scribed.
