ArrARArus ron UTILIZING me HEAT or coke-cakes.

To all whomit may concern:

Be it knownthat I, CARL SEMMLER, acitizen of the German Empire, residing at lViesbaden, "Germany, have invented new a and useful Improvements in Apparatus for Utilizing the Heat of Coke-Cakes, 'of which the following is a specification.

This invention relates to a novel apparatus for utilizing the heat inherent in the able amount of heat is wasted. According to the present invention this heat is recovered by discharging the coke cakes from the oven into a jacketed chamber the double walls of which are cooled by a heat absorbing agent such as water. The latter ispreferably sent throughthe jacket under a comparatively high pressure and after having taken up the heat, is conveyed to an accumulator to give up its heat in the form of utilizable steam, the gases formedtluring the cooling of the coke being carried away through a separate discharge duct. The steam thus generated may either be directly used for power or heating purposes or it may be otherwise employed. By the above described method, the heat inherent in the fresh coke is not only effectively recovered, but the resulting coke is obtained in a perfectly dry state and in the form of comparatively big lumps, distinguished from the coke hitherto obtained by the absence of coke dust. At the same time, the entire process may be carried out in a more economicalmanner, because any repairing of the quenching devices, caused by the acid produced, is obviated.

In the accompanying drawing: Figure 1 is a diagrammatic sectional elevation of an apparatus for the utilization of the heat of fresh coke embodying my invention; Fig. 2 a similar elevation of modification thereof; Fig. 3 a horizontal cross section through a modified form of the cooling chamber; Fig. 4 a longitudinal section of Fig. 3; Fig. 5 illustrates diagrammatically a coke conveying mechanism constructed according to my invention; and Fig. 6 shows the coke discharging means.

It may here be stated that in the several figures, the pipes for the cold heat carrier,

for thehot carrier and for the steam are re spectivelyindicated by full, dotted and dot and dash lines.

The coke cake a, after being ejected from the coking chamber, is introduced into a cooling receptacle 2), provided with a double-' walled insert 0. The space 0 formed between the walls of the insert, is by pipe f connected with the lower portion of a heat vaccumulator or vessel 6 and by pipe g with the upper portion thereof. The heat carrier 0?, such as distilled water or any other liquid incapable of forming segregations is, by pump 7, withdrawn from accumulator e .and forced into .jacket 0 while the heated carrier is returned to accumulator 6 through pipe 9, thus forming a cycle. The pump f should feed the carrier with such a speed through jacket 0 that any formation of steam in the same, is effectively prevented, for which purpose, pipe 9 is advantageously provided with a back pressure valve 9 so that a certain overpressure may be created within jacket 0 that effectively prohibits the generation of steam therein. After the carrier has passed said valve its pressure is relieved so that a lively formation of steam is effected which may be conveyed through pipe 72, to a suitable engine or other steam consuming appliance i. The condensates formed in the latter, are'either returned to accumulator e, or they are conveyed through pipe is and pump k into jacket 0 as illustrated in Fig. 1, thus completing the cycle of the heat carrier. The gases generated during the cooling of'the coke within receptacle b are preferably carried off through a tube 0 to be either permitted to escape into the atmosphere or to be collected for any suitable purposes.

In lieu of directly utilizing the heat carrier in the heat consuming apparatus 2', it may be employed for creating another cycle for which purpose, accumulator e cooperates with container Z filled with a vaporous fluid. The heated fluid is through pipe 71. conveyed to engine 2', while the condensate formed is through pump 10 and pipe k returned to container Z.

It is immaterial in which particular way the cooling chambers for the coke are constructed, a condition being however that their jackets are passed through by the heat carrier under pressure, so as to prevent the formation of steam and cause the latter to take place in the accumulator only. it would of course also be possible to permit the generated steam to escape into the atmosphere, or to condense the same by cooling it by an air or Water current Without departing from the spirit of my invention, but it is obvious that such a partial carrying out of my method would be highly unprofitable.

In Figs. 3 and 4 thecooling chamber is 7 shown to consist of a bottom plate or base m 10;

upon which is removably supported a hood n jacketed as at 0 V These-bipartite cooling chambers have the advantage that the-hood which preferably alone is provided with a 'coolingjacket, may, by a double hose 7) be'connected to a fixed double pipe line (7 for admitting and Withdrawing the heat carrier (Fig. 5). After the temperature of thecoke cake has been sufiiciently reduced, hood n'is removed from bottom section m,

and is shifted laterally.- lhe coke cake is thus permitted to spread upon bottom m, and may be conveyed to a carriage or its place'of utilization by suitable means 8.

said fluid through said jacket, and pressurecontrolling means adapted to be passed by the fluid subsequent to its passage through the jacket for maintaining the pressure of the fluid inclosed within said jacket at a height that precludes its vaporization,

while permitting such vaporization of the fluid after its passage through such pressure-controlling means.

2. Apparatus for cooling coke comprising a receptacle having a jacket and adapted to receive a charge of glowing coke, the re ceptacle-jacket being adapted to receive a heat-absorbing fluid, means for conveying said fluid through'said jacket, and a back pressure valve adapted to be passed by the fluid subsequent to its passage through the jacket for maintaining the pressure of the fluid inclosed within said jacket at a height that precludes its vaporization, while permitting such vaporization of the fluid after its passage through said back pressure valve.

3. Apparatus for cooling coke comprising a base, a jacketed hood removably supported thereby, stationary pipe lines for conducting a heat carrier, and means for connecting the hood-jacket to said pipe lines.
