Description

Verfahren zur Verbesserung der Innenabsaugung bei Verkokungsöfen Bei der Verwendung senkrechter, in den Gassamm,elraum mündender Hohlräume im Brennstoffinhalt von Verkokungsöfen hat sich gezeigt, daß seine gewisse Zeit nach Beginn der Entgasung aus den Hohlräumen nicht nur an schweren Kohlenwasserstofben reiche sog. Innengase aufsteigen, sondern daß, wenn die Hohlräume bis nahe an die Kammersohle reichen, aus den untersten Schichten des Kammerinhaltes, deren Entgasung bereits weitgehend fortgeschritten war, ein heißes wasserstoffreiches Gas in die Hohlräume eindrang und eine Überhitzung der Randschichten der Hohlräume bewirkte, wodurch der Abzug der Innengase -durch die Hohlräume erschwert wurde.Process for improving internal extraction in coking ovens Bei the use of vertical cavities in the fuel content that open into the gas sump of coking ovens has been shown that its certain time after the start of degassing so-called internal gases from the cavities are not only rich in heavy hydrocarbons rise, but that when the cavities reach close to the bottom of the chamber, from the lowest layers of the chamber contents, which have already largely been degassed had progressed, a hot hydrogen-rich gas entered the cavities and overheating of the outer layers of the cavities, causing the fume cupboard the internal gases -was made more difficult by the cavities.

Gemäß der Erfindung soll - diesem übelstand dadurch abgeholfen werden, daß nach der Erzeugung der Hohlräume ein gasdichter Abschluß derselben nach der Kammersohle zu hergestellt wird.According to the invention - this deficiency should be remedied by that after the production of the cavities, a gas-tight closure of the same after Chamber sole is made to.

Ein Mittel,-einen solchen gasdichten Abschluß herzustellen, besteht darin, daß nach der' Bildung der Hohlräume die unterhalb derselben liegende Köhle durch Stampfen verdichtet wird, beispielsweise indem eine mit flachem Boden versehene Stange in die Hohlräume eingeführt und= "mehrmals auf den Boden der Hohlräume falllengelassen oder aufgedrückt wird. Eine solche Verdichtung durch Stampfen kann--auch ersteinige Stunden nach der Bildung der Hohlräume vorgenommen oder, wenn sie gleich zu Beginn stattgefunden hat, später wiederholt werden. Vor einer späteren Verdichtung kann auch eine gewisse Menge urverkokter Kohle -in die Hohlräume eingeschüttet werden.There is a means of producing such a gas-tight seal in the fact that after the formation of the cavities, the cavity below them is compacted by ramming, for example by placing a flat bottom Rod inserted into the cavities and dropped several times to the bottom of the cavities or is pressed. Such compaction by pounding can - even the first few Made hours after the formation of the cavities or when they are right at the beginning has taken place, to be repeated later. Before a later compaction can Also a certain amount of coked coal can be poured into the cavities.

Eine andere Möglichkeit, einen gasdichten Abschluß der Hohlräume nach der Kammersohle zu herzustellen, besteht darin, daß in die Hohlräume ein dickflüssiger Teer in solcJier Menge eingefüllt wird, daß er den Boden der Hohlräume bedeckt. Der Teer sickert dabei in die Kohle ein und wird durch die an der Kammersohle herrschende Hitze schnell teilweise verkrustet, so daß ebenfalls ein gasdichter Abschluß entsteht.Another possibility is to create a gas-tight seal for the cavities To produce the chamber sole consists in placing a thick fluid in the cavities Tar is poured in such an amount that it covers the bottom of the cavities. The tar seeps into the coal and is replaced by the one prevailing on the floor of the chamber Heat quickly and partially encrusted, so that a gas-tight seal is also created.
