Description

Verfahren zum Herstellen von Briketten aus Steinkohlenhalbkoks Gut backende Steinkohle wird bis auf weiteres noch in Koksöfen entteert. Schlechter backende Kohlen wird man in Schwelöfen mehr und mehr verschwelen, um den wertvollen Urteer zu gewinnen. Der anfallen-de Halbkoks ist jedoch meist so wenig gebacken, daß er sich weder für den Versand noch zur Verwendung in gewöhnlichen Ofen eignet.Process for the production of briquettes from hard coal semi-coke Gut Baking coal will be tarred in coke ovens until further notice. Worse Baking coals will be smoldered more and more in smoldering ovens to make the valuable ones To win primal tar. The resulting semi-coke, however, is usually so little baked, that it is neither suitable for shipping nor for use in ordinary ovens.

Es wird daher mit allen Mitteln versucht, Halbkoks zu brikettieren. Dies ist einerseits durch Pechzusatz erreicht worden, und andererseits ist vorgeschlagen worden, gleichzeitig mit dem Bindemittel aus Ersparnisgründen eine geringe Menge Brennstoffstaub zu zerstäuben und dem Brikettiergut zuzublasen. Es erscheint aber als ein Unding, zunächst aus der Kohle die backenden Bestandteile herauszudestillieren und sie nachher wieder zuzusetzen. Weiter sind Versuche mit Zusatz von Sulfitablauge gemacht worden. Diese hatten aber keinen Erfolg, weil die Brikette nicht genügend wetterbeständig waren.Every effort is therefore made to briquette semi-coke. This has been achieved, on the one hand, by adding pitch and, on the other hand, has been proposed at the same time as the binder for reasons of economy a small amount To atomize fuel dust and blow it to the briquette. But it appears as an absurdity to first distill the baking ingredients out of the charcoal and to add them again afterwards. There are also experiments with the addition of sulphite waste liquor been made. However, these were unsuccessful because the briquette was insufficient were weatherproof.

Die Erfinder haben festgestellt, daß Steinkohlenhalbkoks sich unter Zumischung von geeignetem Steinkohlenstaub bei Temperaturen von 300 bis 500° C leicht brikettieren läßt. Die Verwendung gerade dieses wohlfeilen und in unbegrenzten Mengen zur Verfügung stehenden Staubes ist von hohem technischen Werte.The inventors have found that hard coal semi-coke can easily be briquetted at temperatures of 300 to 500 ° C. with the addition of suitable hard coal dust. The use of this cheap and in unlimited quantities available dust is of high technical value.

Zum Brikettieren eignen sich beispielsweise folgende Mischungen: 8 Gewichtsteile Halbkoks aus Staubkohle der Hohenzollerngrube und 2 Gewichtsteile Steinkohlenstaub der Hohenzollerngrube OIS oder 6 Gewichtsteile Steinkohlenstaub der Delbrückschächte und q. Gewichtsteile Staubkohle der Delbrückschächte OIS.The following mixtures, for example, are suitable for briquetting: 8 Parts by weight of semi-coke from pulverized coal from the Hohenzollern mine and 2 parts by weight Hard coal dust from the Hohenzollern mine OIS or 6 parts by weight of hard coal dust the Delbrück shafts and q. Parts by weight of pulverized coal from the Delbrück shafts OIS.

Analog verfährt man bei der Wahl anderer für diese Zwecke geeigneter Mischungsverhältnisse.The same procedure is used when choosing others that are more suitable for these purposes Mixing ratios.

Es hat sich herausgestellt, daß es häufig zweckmäßig ist, die Brikettierung nicht in einer Phase vorzunehmen, sondern die Pressung stufenweise auszuführen, wie es für Steinkohlenstaub allein bereits bekannt ist. Beispielsweise preßt man die Mischungen von Halbkoks und Kohlenstaub bei etwa 33o° C vor und preßt sie dann bei etwa 38o° C fertig.It has been found that it is often expedient to use briquetting not to be carried out in one phase, but to carry out the pressing step by step, as is already known for coal dust alone. For example, you press the mixtures of semi-coke and coal dust at about 33o ° C and then pressed ready at around 38o ° C.
