Description

Verschwelen von Steinkohle in einem Drehrohrofen o. dgl. In dem Hauptpatent 437$i3 ist ein Verfahren zum Verschwelen von Steinkohle in einem Drehrohrofen o. dgl. beschrieben, bei welchem das Schwelgut durch Außenbeheizung sofort nach seinem Eintritt in den Ofen auf die Teerbildungs- bzw. Erweichungstemperatur erhitzt wird. Gemäß der vorliegenden Erfindung sollen zur Herbeiführung der gewünschten Wirkung und um das Schwelgut möglichst schnell auf die Teerbildungstemperatur zu erhitzen, zusätzliche Mengen von Heizgasen durch einen besonderen Heizkanal in der Nähe der Eintragsstelle für das Schwelgut der Schnellschwelzone zugeführt werden.Smoldering of coal in a rotary kiln or the like. In the main patent 437 $ i3 is a process for carbonizing hard coal in a rotary kiln or the like. Like. Described, in which the Schwelgut by external heating immediately after his Entering the furnace is heated to the tar formation or softening temperature. According to the present invention are intended to produce the desired effect and in order to heat the carbonized food to the tar formation temperature as quickly as possible, additional quantities of heating gases through a special heating duct near the Entry point for the smoldering material are fed to the rapid smoldering zone.

In der Zeichnung ist schematisch eine Ausführungsform des Erfindungsgegenstandes dargestellt.An embodiment of the subject matter of the invention is shown schematically in the drawing shown.

a ist der von außen beheizte - Drehrohrofen, um welchen die Heizgase in Kanälen herumgeführt werden. Gemäß der Erfindung soll nun eine zusätzliche Menge von Heizgasen zur Schnellschwelzone b hinzugeführt werden, und dies geschieht von einer besonderen Feuerung C aus, wo durch den Kanal d die Zusatzheizgase mit einer Temperatur von etwa iooo° C und darüber an die Scbnellscnwelzone herangeführt werden, so daß das am hinteren Ende des Ofens eintretende Schwelgut sofort bei seinem Eintritt auf eine hone Temperatur gebracht wird.a is the externally heated - rotary kiln, around which the heating gases be shown around in canals. According to the invention, an additional amount should now of heating gases are added to the rapid melting zone b, and this is done by a special furnace C, where the additional heating gases with a Temperatures of about 100 ° C and above are brought to the rapid decompression zone, so that the smoldering material entering at the rear end of the furnace immediately upon its entry brought to a high temperature.
