Description
"UNITED sTATEs PATENT OFFICE.
HEINRICH KOPPERS, OF ESSEN-bN-THE-RUHR, GERMANY,
PROCESS OF QUENGHING COKE.
No Drawing.
quenching, water must necessarily be used in large quantities, ,of which the partly cooled coke, owing to its porous structure, will absorb a considerable amount. T he water thus introduced into the coke is notonly an unnecessary ballast during shipment, but is highly undesirable when using the coke in blast or eupola furnaces. Moreover, the
cold water, when sprayed on the whitehot coke in large qu'antities,-willcause the coke to cool suddenly and become brittle,
and this'britt-leness cause -fit to crack, so that the mechanical resistatnt'c of thecoke is greatly impaired.
This invention relates to a novel process of quenching white hot coke which overcomes all these disadvantages. For this purpose the white hot coke coming from the (501w chamber is discharged into a bath con-.
tainiug a quantity of water which is of a depth t completely immerse the coke. The water should be preheated to such adegree that the heat contained in the coke 1s suificient to raise the water temperature tot-he boiling point. In this way the coke, while submerged, is not able to take up any water, because its pores will be immediately filled with steam. Each lump of hot coke, While being submerged in boiling water, is ,sur-
rounded by a steam jacket and consequently Y the heat is gradually extracted from the.
- coke and there is no sudden cooling to cause l-irittlencss, which, in turn, would result in cracking. WV hen the coke. lumps have been.
immersed for such a len th of time that they are covered with C )()l( crusts, while their Specification of Letters Patent. Application filed June 5, 1909. Serial No. 500,302.
' of-each coke lump-by crust, and then exposing the coke to the a.t-

cores aregstill hot, the water is run off. Even at'this stage, the water still adhering to the coke lum'ps will not enter the pores thereof, but will be evaporated, owing to ,the heat emanating from the cores of said lumps. The small amount of water produced by the condensation of the steam c011- tained in the pores isso insignificant that it may practically be ignored.
In carrying out my invention I proceed as follows: An open tank car traveling on a track arranged in front of the battery of ovens and part1 filled with warm water is run in front 0 level that the coke discharged from theoven falls into the car andfor the purpose of evenly distributing the charge, the car issimultaneously moved transversely toward the cokin chamber. This prevents the coke from. fal ing against a hard surface and from being broken into small pieces. When the water has been brought to a. boiling point and each piece of-coke is covered with a cooled crust, the water is run oif, and then the tankis tirpped to unload the coke. The water still adhering to the several pieces of coke will not penetrate into the same, owing to the hot state of" the coke, but will be evaporatediand thus driven off.
I claim? Process of quenching coke, which consists in immersing the output of. each coking chamber of a coke oven in hot water for a length of time sufiicientto envelop the core a cooled protecting mosphere', whereby a uniform quality of non-brittle coke of the entire output 15 produced.
the coking chamber to be. emptied. The track should occupy such a Si ned by me at J oliet, Will county,
