Description

Verfahren zum Brikettieren von Steinkohlenstaub. Wird Kohlenstaub, möglichst unter Abschluß von Luft, erhitzt, so tritt in der Kohlensubstanz eine physikalische Veränderung auf. Obwohl der Kohlenstaub äußerlich unverändert bleibt und auch nicht aneinanderbackt, läßt er sich, beginnend von etwa i 8o bis 2q.0° C, ohne fremde Bindemittel durch Druck zu festen Briketten verpressen. Je höher man mit der Temperatur geht, desto niedriger wird der erforderliche Druck; doch darf die Temperatur nur so weit gesteigert werden, daß wohl Kohlensäure, aber keine Schwelgase entweichen.Process for briquetting hard coal dust. Will coal dust If possible with the exclusion of air, if heated, a carbon substance occurs physical change. Although the coal dust remains externally unchanged and it does not stick together either, starting from about i 8o to 2q.0 ° C, pressed into solid briquettes by pressure without external binding agents. The higher one goes with temperature, the lower the pressure required; but the temperature may only be increased so much that carbonic acid is possible, but none Smoldering gases escape.

Das neue Verfahren besteht also darin, daß Steinkohlenstaub auf eine Temperatur erhitzt wird, bei der noch keine Schwelgase entweichen, die Kohle aber bereits hinreichend plastisch zum Brikettieren ist, und daß bei dieser oder einer ähnlichen Temperatur die Brikettierung ohne Verwendung eines Bindemittels vorgenommen wird.The new method consists in that coal dust on a Temperature is heated at which no smoldering gases escape, but the coal is already sufficiently plastic for briquetting, and that with this or one The briquetting is carried out at a similar temperature without the use of a binder will.

Beispiel i.Example i.

Eine nicht kokende oberschlesische Steinkohle wird t 5 Minuten auf 350'C gehalten und dann mit einem Druck von i 5o kg/qcm gepreßt. Das Brikett ist hart, wetterbeständig und nicht abreibbar. Während des Erhitzens entweicht Kohlensäure und Konstitutionswasser; Schwelgase oder Teer entstehen nicht.A non-coking Upper Silesian coal is kept at 350 ° C. for 5 minutes and then pressed with a pressure of 150 kg / cm 2. The briquette is hard, weatherproof and cannot be rubbed off. During the heating process, carbonic acid and constitutional water escape; Smoldering gases or tar do not arise.

Bedspiel2. Die Durchschnittsförderung einer oberschlesischen Grube, welche nur sandigen Koks gibt, wird 2o Minuten auf 36o° C gehalten und dann mit einenii Druck von ioo kg/qcm gepreßt. Die Brikette und die Nebenprodukte sind wie bei Beispiel i.Bedspiel2. The average production of an Upper Silesian mine, which gives only sandy coke, is kept at 36o ° C for 20 minutes and then with pressed at a pressure of 100 kg / sq cm. The briquette and by-products are like in example i.
