Description

Verfahren zur Herstellung von Braunkohlenbriketts Das Trocknen der Braunkohle nach dem Fleißner-Verfahren hat bisher nur für stückige Kohle Verwendung gefunden, die nicht brikettiert werden sollte. Kohle, die für die Herstellung von Briketts bestimmt war, wurde dagegen bisher nur in der bekannten Weise, z. B. in Röhrentrocknern oder Telleröfen durch indirekte Einwirkung von Wasserdampf oder auch in Feuergastrocknern, getrocknet. Das Bestreben ging dahin, Kohle in immer kleinerer Korngröße zu verwenden, die für die Pressung besonders vorteilhaft ist.Process for the production of brown coal briquettes The drying of the Lignite according to the Fleißner process has so far only been used for lumpy coal found that should not be briquetted. Coal used for the production of Briquettes was intended, however, was previously only in the known manner, for. Am Tube dryers or plate ovens by indirect action of steam or also in fire gas dryers, dried. The endeavor was to get coal in to use smaller grain size, which is particularly advantageous for the pressing.

Braunkohlen, die einen verhältnismäßig' hohen Prozentsatz an leicht wasserlöslichen Salzen enthalten (z. B. Natriumchlorid und Natriumsulfat), liefern ein schlechtes Brikett. Das Brikett ist wenig wetterbeständig und zerfällt bei der Verbrennung sehr leicht.Lignite, which has a relatively 'high percentage of light containing water-soluble salts (e.g. sodium chloride and sodium sulphate) a bad briquette. The briquette is not very weather-resistant and disintegrates during the Burns very easily.

Es wurde nun gefunden, daß Kohlen mit hohem Anteil von leicht wasserlöslichen Salzen ein ausgezeichnetes Brikett geben, wenn sie nach dem Fleißner-Verfahren getrocknet sind, da hierbei. ein erheblicher Teil der wasserlöslichen Bestandteile mit dem bei der Trocknung ausgetriebenen Wasser entfernt wird. Außerdem ist die Wassergehaltsspanne, die zur Erzielung eines guten Briketts möglichst gering sein muß, bei der Fleißner-Trocknung geringer als bei dem bisher angewendeten Trocknungsverfahren.It has now been found that coals with a high proportion of easily water-soluble Salts make an excellent briquette when dried using the Fleissner method are there here. a significant part of the water-soluble components with the water expelled during drying is removed. In addition, the water content range is which must be as small as possible in order to obtain a good briquette, in the case of Fleissner drying less than with the previously used drying process.

Da ferner der Dampfverbrauch bei der Fleißner-Trocknung wesentlich niedriger als bei der bisher üblichen Dampftrocknung liegt, stellt das Verfahren einen wesentlichen Fortschritt auf dem Gebiete der Braunkohlenaufbereitung für Brikettierzwecke dar.Since the steam consumption in Fleißner drying is also significant is lower than with the previously customary steam drying, the process a significant advance in the field of processing lignite for briquetting purposes represent.

Es ist zwar bereits bekannt, zur Vorbereitung von Brennstoffen, wie Torf, Braunkohle, Steinkohle, Rauchkammerlösche, für die Brikettierung diese mit Wasser oder angesäuettem Wasser zur Entfernung oder Verminderung der für die Haltbarkeit der Briketts schädlichen Salze auszuwaschen. Nach dem neuen Verfahren. wird jedoch das Salz ohne Wasserzugabe durch das in der Kohle bereits befindliche Wasser unter Druck entfernt, wobei gleichzeitig mit der Aussalzung auch eine Trocknung der Kohle stattfindet.Although it is already known how to prepare fuels Peat, brown coal, hard coal, smoke box extinguisher, for briquetting these with Water or acidified water to remove or reduce the shelf life to wash out harmful salts from the briquettes. According to the new procedure. will however the salt without adding water through the water already in the coal Pressure is removed, with the coal being dried out at the same time as the salting out takes place.
