Description

Verfahren zum Einbinden von mulmiger Braunkohle usw.n Die Anwendung von anorganischen Bindemitteln zum Einbinden von Kohlenfein ist bekannt.Method of incorporating queasy brown coal, etc. n The application of inorganic binders for binding carbon fines is known.

Gebrannter Kalk, Ton, Baryt und Chlormagnesium wurden bisher als Bindemittel vorgeschlagen und einzeln als Zusätze zum Kohlenfein zugeschlagen; ebenso wurde Magnesit unter Zusatz von Chlormagnesium als Bindemittel empfohlen.Quick lime, clay, barite and chlorine magnesium were previously used as binders proposed and added individually as additions to the fine coal; as was Magnesite with the addition of magnesium chloride is recommended as a binding agent.

Teilweise ergaben diese Stoffe zu Anfang feste Brikette; jedoch schon in kurzer Zeit zerfielen die so hergestellten Brikette, was nach Ansicht des Erfinders seine Ursache in dem Umstande hat, daB nach Abgang des im Brikett enthaltenen Wassers diese Bindemittel sich mit der im Kohlenfein enthaltenen und in der Luft beständig vorhandenen Kohlensäure unter Volumenvergrößerung anreicherten und so das feste Gefüge der Brikette zersprengten.In some cases, these substances initially resulted in solid briquettes; but yes In a short time, the briquettes produced in this way disintegrated, which in the opinion of the inventor has its cause in the fact that after the water contained in the briquette has passed away These binders are consistent with that contained in the fine carbon and are stable in the air existing carbon dioxide enriched with an increase in volume and so the solid The structure of the briquette shattered.

Anders gestaltet sich der chemische Vorgang in den Briketten bei gleichzeitiger Anwendung mehrerer Bindemittel, welche dann so gewählt werden müssen, daß sie mit den im Kohlenfein enthaltenen anorganischen Beimengungen zusammen eine chemische Verbindung eingehen, welche dem Brikett die nötige Härte geben und nicht durch Kohlensäure dissoziiert werden.The chemical process in the briquettes is different at the same time Use of several binders, which must then be chosen so that they with the inorganic admixtures contained in the carbon fines together form a chemical one Form a connection that gives the briquette the necessary hardness and not through carbonic acid to be dissociated.

Bei dem neuen Verfahren kommen als Bindemittel anorganische Stoffe zur Anwendung, welche, in geringen Mengen angewandt, durch ihre Zusammenmischung im Verein mit den im Brikettiergut enthaltenen anorganischen Bestandteilen Verbindungen ergeben, welche die brikettierten Kohlen steinhart und versandfähig machen, ohne deren Brennbarkeit zu beeinflussen. Die Bindemittel sind Erdalkalien, feuerfester Ton, Kalk (Ca0), Baryt (gebrannt) und Chlormagnesium; sie werden in passenden Verhältnissen je nach der Beschaffenheit des zu brikettierenden Kohlengutes diesem zugesetzt, z. B. 2 Prozent feuerfester Ton, 2 Prozent Kalk (Ca0) i Prozent Chlormagnesium oder bei stark Schwefel enthaltendem Gut i Prozent feuerfester Ton, 2 Prozent Kalk (Ca0), 2 Prozent gebrannter Baryt; in diesem Falle findet ein Zusatz von Chlormagnesium nicht statt.In the new process, inorganic substances are used as binders for use, which, applied in small amounts, by mixing them together in combination with the inorganic constituents contained in the briquetting material, compounds result, which make the briquetted coals rock-hard and ready for dispatch without to influence their flammability. The binders are alkaline earths, more refractory Clay, lime (Ca0), barite (burnt) and chlorine magnesium; they will be in appropriate proportions depending on the nature of the coal to be briquetted added to it, z. B. 2 percent refractory clay, 2 percent lime (Ca0) i percent chlorine magnesium or in the case of goods with a high content of sulfur i percent refractory clay, 2 percent lime (Ca0), 2 percent calcined barite; in this case there is an addition of magnesium chloride does not take place.

Nach längstens vier Tagen sind die nach diesemVerfahren hergestelltenBrnkette so fest geworden, daß sie versandfähig sind. In der angegebenen Zeit haben sie den größten Teil ihres Wassergehaltes verloren und können sofort verfeuert werden. Das Formen der Brikette findet in Maschinen statt, welche das zu brikettierende Kohlengut mit den Bindemitteln innig vermischen und dann unter geringem Druck als Brikette ausstoßen.After a maximum of four days, the chain produced by this process will be have become so firm that they can be shipped. In the given time you have the Most of their water content is lost and can be burned immediately. That Forming the briquette takes place in machines, which the coal to be briquetted Mix thoroughly with the binders and then under low pressure as a briquette eject.
