Description

Drehrohrofen zum elektrischen Brennen, Rösten und Sintern von Zement, Kalk, Dolomit, Magnesit u. dgl. Es ist bereits vorgeschlagen worden, bei Drehöfen zum Brennen von Zement, Kalk o. dgl. die Kohlen- oder Ölfeuerung durch elektrische Heizung unter Erzeugung eines Hochspannungsflammenbogens zu ersetzen. Die Elektroden und der Lichtbogen lagen dabei in der Ofenachse. Das bedingt entweder lange Elektroden oder eine Zerlegung des Drehofens .in mehrere Abteilungen, wodurch sich Schwierigkeiten ergeben.Rotary kiln for the electrical firing, roasting and sintering of cement, Lime, dolomite, magnesite and the like have already been proposed in rotary kilns for burning cement, lime or the like. Electric coal or oil firing Replace heating with generation of a high voltage flame arc. The electrodes and the arc lay in the furnace axis. This either requires long electrodes or a division of the rotary kiln into several departments, which creates difficulties result.

Gemäß der Erfindung sollen diese Übelstände, vermieden wenden dadurch, daß die Zuführung des Stromes vom Umfang ,des Ofens her erfolgt, ohne .daß dabei die Möglichkeit verlorengeht, den Lichtbogen in der Richtung der Ofenachse zu verschieben.According to the invention, these evils should be avoided by that the current is supplied from the periphery of the furnace, without .daß thereby the possibility of shifting the arc in the direction of the furnace axis is lost.

Die Elektroden b werden erfindungsgemäß von der Stirnseite der erweiterten ,Sinterzone aus in das Ofeninnere eingeführt, so daß der Lichtbogen radial in :der Trommel liegt. Es kann eine _ Zündungselektrode c vorgesehen sein, welche zweckmäßig im Innern des Ofens, und zwar von der Kühlzone aus längsverschieblich gelagert ist. Durch Verschieben der Elektroden b kann .die Lage ,des Lichtbogens verändert werden: Es ist nicht notwendig, daß die Elektroden parallel der Ofen--achse liegen, wenn nur beim Verschieben der Elektroden der Lichtbogen in Richtung der Ofenachse verschoben wird.According to the invention, the electrodes b are expanded from the end face of the , Sintering zone from introduced into the furnace interior, so that the arc radially in: the Drum lies. An ignition electrode can be provided which is expedient is mounted in the interior of the furnace, namely from the cooling zone from longitudinally displaceable. The position of the arc can be changed by moving the electrodes b: It is not necessary for the electrodes to be parallel to the axis of the furnace when The arc is only shifted in the direction of the furnace axis when the electrodes are moved will.
