Es ist bekannt, in die Kammerfüllungen liegender Koksöfen Dampf einzuführen, um die Ausbeute an Gasen aus den Kohlen zu erhöhen und zu verbessern; die Zuführung des Dampfes in das Ofeninnere fand bisher durch die Seitenwände statt. Dabei werden aber die Wände abgekühlt und der Dampf muß durch die an den Wänden zunächst sich bildenden, immer zunehmenden KokslagenIt is known to introduce steam into the chamber fillings of coke ovens in order to to increase and improve the yield of gases from the coals; the feed of the steam into the furnace interior has previously taken place through the side walls. Be there but the walls cooled down and the steam had to get through the walls first forming, ever increasing layers of coke
ίο hindurchtreten, um zu den in der Kammermitte befindlichen, noch nicht verkokten Kohlen zu gelangen.ίο step through to get to the one in the middle of the chamber coal that has not yet been coked.
Dieser doppelte Ubelstand wird durch die Erfindung dadurch vermieden, daß der Dampf, ohne Störung des fortschreitenden Verkokungsprozesses, in der Richtung der mittleren Längsachse des Kammerraumes von unten in diesen eingeleitet wird, wodurch die Einwirkung des Dampfes, von der Mitte ausgehend, nur auf unverkokte Kohle trifft und großer Dampfverbrauch und Wärmeverluste vermieden werden.This double disadvantage is avoided by the invention in that the steam, without disturbing the progressive coking process, in the direction of the middle The longitudinal axis of the chamber space is introduced into it from below, whereby the effect of the steam, starting from the middle, only encounters uncoked coal and large steam consumption and heat losses are avoided.
In der Zeichnung ist in schematischen Schnitten ein Ausführungsbeispiel eines Koksofens dargestellt, welcher das vorstehend angegebene Kennzeichen besitzt.The drawing shows an exemplary embodiment of a coke oven in schematic sections shown, which has the mark indicated above.
Fig. ι zeigt einen senkrechten Schnitt durch den Ofen, teils durch die Mitte eines Ofenraumes und teils durch die Heizzüge.Fig. Ι shows a vertical section through the furnace, partly through the middle of a furnace chamber and partly through the heating flues.
Fig. 2 stellt zwei zu dem Schnitte nach Fig. ι senkrecht geführte Schnitte nach A-B bezw. nach C-D dar.Fig. 2 shows two to the sections according to Fig. Ι vertically guided cuts to AB respectively. according to CD .
In der Figurengruppe 3 schließlich sind einige Ausführungsformen von durchlochten Bodensteinen veranschaulicht. Das Beheizungssystem ist beliebig zu wählen; der dargestellte Ofen zeigt z. B. die Kanalführung gemäß Patent 158005.Finally, in group 3 of figures, some embodiments are perforated Floor stones illustrated. The heating system can be chosen arbitrarily; the one shown Furnace shows z. B. the channel guide according to patent 158005.
Der Boden der Kammern wird von Steinen a gebildet, welche einen mittleren Kanal b mit nach oben gerichteten und an der Oberseite ausmündenden Abzweigungen c besitzen.The bottom of the chambers is formed by stones a , which have a central channel b with branches c pointing upwards and opening out at the top.
Sämtliche Steine α eines Ofenbodens sind so'gelegt, daß durch die Kanäle b ein einziger, in der Sohle des Ofenraumes liegender Längskanal e gebildet wird.All the stones α of a furnace floor are placed in such a way that the channels b form a single longitudinal channel e located in the bottom of the furnace space.
In die Längskanäle e wird während des Verkokungsprozesses durch ein Rohr d überhitzter Dampf eingeblasen, der durch die Abzweigungen c im wesentlichen in Richtung der mittleren Längsachse jedes Kammerraumes von unten in diesen eintritt und ohne Störung des Verkokungsprozesses eine erhöhte Ausbeute an Teer und Ammoniak aus den Gasen bewirkt.During the coking process, superheated steam is blown into the longitudinal ducts e through a pipe d , which enters through the branches c essentially in the direction of the central longitudinal axis of each chamber space from below and, without disturbing the coking process, an increased yield of tar and ammonia from the gases causes.
