Toall whom'it may concern:

Be it known that I, Armor Mom'nm, a citizen of Switzerland residing at Oberwintert'hur, Switzerland, ave invented certain new and useful improvements in Coke-Cooling Apparadis, oi'whichthe following is a specification.-

It is already known to utilize the high temperatures of hot coke leaving the retorts, for the generation of water gas, by quenching the coke by introducing steam'in an airtightly closed chamber and passing the water gas formed to further utilization. The steam required for this purpose is uiually tapped -from an existing steam boiler p ant.

This process has the drawback, that only the heat of an upper zone of temperature of the incandescent coke can be employed since with a temperature of the coke below 600 degrees centigrade ageneration of water gas will, no longer take 700 degrees centigrade it will-become uneconomieal t9 such an extent, that it can not be carried through practically,- The heat oi the lower zone of temperature, that is to say below 7 00 C. is thus lost. Besides it is necessary to generate the' steam required. for the generation ofwater gas by a corresponding consumption of fuel, which procedure will. minimize the profit obtained by the formation of water gas.

In the new process according to the invention both the water gas and the steam required for that purpose are obtained by means of the heat contained in the incandescent coke. ing the heat yielded at an upper zone of temperature from a quantity of coke contained in a receptacle for making water gas, while the heat gained at a lower zone of temperature irom the same charge of coke is used for the: generation of the steam required for the formation of water gas, the whole procedure with the object in view to dispense with a specialsource of heat for the genera tion of steam.

The installation for carrying out this process. may be of such construction that the stoking hole or fireplace of the boiler serving for thegeneration of steam, is connected with the receptacle containing the coke by means of pipes capable of being shut, and through which, after opening of the shutting-oil members, the gasescontained in both the communicating chambers, for the pur- The process consists in utiliz pose of conneying the heat of the coke into the boiler, are forced by means of a blower m "a cycle through the rece tacle and the boiler. The plant may also e of such construction, that condult through which the water gas generated may be conducted either directly or through the stoking hole of the boiler to the place of consumption.

A mode of drawing.

a is a receptacle into which the coke coming from the retorts is introduced throu h the opening I) and after the finishingof-t e cooling process is discharged through the outlet 0. 0! represents a boiler, whose stoking hole is connected at the top with the receptacle a by means of the pi e e and at the bottom by the pipe f A bower 'v is ar ranged in the duct fforcing the gases contained in the receptacle for the coke and the etching hole in a cycle through both chambers, in order to transfer the heat, withdrawn from the coke by the gas, to the boiler. g and h are shutting-oil" members provided for the purpose of temporarily interru ting the communication between the coke 0 amher and the stoking hole.

construction is shown in the Connected with. the steam chamber of theboiler is a steam pipe c" leadin to the coke chamber, by means pf which t e steam required for thegeneration of Water gas is conducted to the coke. For regulating the admission of steam said pipe is provided with a controlling member is. The water gas generated is passed throu h the pipe Z provided with a closing mem r m to an accumulator or as the case may be to the place of consumption.

Another pipe at having a closing member 0 serves for conducting the hot water I gas through the etching hole or fire place of the boiler with the ob ect of utilizing the heat of the gas. v

The plant is operated in such a manner, that the total amount of heat yielded b' the first filling of the container 0; is use for the generation of steam. For this purpose the closing members 76, m and o are shut, and e and f opened, and the blower o started, whereby the uses forced through the communicating c numbers in cycle, transfer the heat of the coke to the boiler water,'and cause va o'rization of the latter.

If so cient steamis generated in this way, the container a is discharged and filled pipes are provided again wiehincandescent coke, the closing descent coke by openingihe controlling 5 member is. The water gas generated hereby is conducted through the conduit pipe to the accumulator or piece of consumption re emetweiy. As soon as the coke cooling down has reached a temperature of about W 70%, the members m and 7c are closed, but

g and h opened, and by starting the blower '21 izlie beatsiaill inherent in the coke is again utilized for." the generation of steam. In

this manner is possible to generate the i 4 f s efi sheen: leqnireo 101* one oimation or water gas foiiowing next.

After the complete coolin of the coke the container is clischangeci 2m a new charge of incandescent coke brought in, when after a corresponding adjustment of she olosing members he formmbion of watei gas and the subsequent generation of steam commences anew. Instead of leadi the hot water gas, leaving the coke container, to the accumulator directly or to the place of consumption, said gas can. also be conducted through oponin -the member 0,, where its heat is utilize in an economical way for the further aeration of steam.

Io aim: o A plant for dry cooling coke comprising in combination a cooling chamber, a steam boiler connected therewith, a valved means for introducing steam from the boiler into the chamber, a valved means for drawing oif water-gas and valved means for circuthe boiler by closingthe member m and.

latin a cooling gas through the chamber.-

and t en through the boiler.
