Description

Verfahren zur Herstellung verkokter Brikette aus nichtbackenden Brennstoffen Es ist bereits :ein Verfahren vorgeschlagen worden zur Herstellung sogenannter Kolloidbrikette aus Feinkohle unterVerwendung einer schleimigen kolloidalen Dispersion aus der zu verarbeitenden oder einer anderen Kohle. Die auf diese Weise erzeugten Brikette besitzen, namentlich im feuchten Zustande, keine wesentlich anderen feuerungstechnischen Eigenschaften als die Rohbrennstoffe, aus denen. sie bestehen.Process for making coked briquettes from non-baking fuels A process has already been proposed for the production of so-called colloid briquettes from fine coal using a slimy colloidal dispersion from the to processing or any other coal. The briquette produced in this way do not have any significantly different combustion technology, especially when they are moist Properties than the raw fuels that make up. they exist.

Will man diesen Kolloidbriketten wertvollere Eigenschaften verleihen, wie z. B. rauchlose Verbrennung, reduzierende Wirkung bei chemischen oder hüttenmännischen Prozessen, erhöhte Festigkeit und Wasserbeständigkeit, so liegt die :einzige Möglichkeit hierzu in einer Verkokung.If you want to give these colloid briquettes more valuable properties, such as B. smokeless combustion, reducing effect in chemical or metallurgical Processes, increased strength and water resistance, this is the only possibility this in a coking.

Kolloidbrikette aus nichtbackenden Brennstoffen neigen bei der Verkokung in der Regel zum Zerfallen und sind daher für eine solche Nachbehandlung ungeeignet. Auch lassen sich Kolloidbrikette dann nicht in wirksamer Weise verkoken, wenn sie z. B. aus einem körnigen backenden Brennstoff mit einer Dispersion nichtbackenden Brennstoffs hergestellt sind. Brikette aus einer solchen Mischung würden, wie die Erfahrung gezeigt hat, bei der Verkokung starke Formveränderungen erleiden; aneinanderkleben und unter Umständen zu unförmigen Klumpen verschmelzen, so daß Störungen im Ofengang auftreten würden.Colloid briquettes made from non-baking fuels tend to coke usually to disintegrate and are therefore unsuitable for such post-treatment. Also, colloid briquettes cannot be effectively coked if they z. B. non-baking from a granular baking fuel with a dispersion Fuel are produced. Briquette from such a mixture would like that Experience has shown that coking causes severe changes in shape; stick to each other and, under certain circumstances, fuse to form misshapen lumps, so that faults in the furnace run would occur.

Nach der Erfindung werden verkokte Brikette aus nichtbackenden Brennstoffen aller Art und einer zum Einbinden dienenden kolloidalen Kohlendispersion von schleimiger Beschaffenheit dadurch erzeugt, daß die zum Einbinden des nichtbackenden Brennstoffes dienende kolloidale Dispersion von schleimiger Beschaffenheit aus kokender Kohle bereitet wird.According to the invention, coked briquettes are made from non-baking fuels of all kinds and a colloidal carbon dispersion of slimy used for binding Characteristics produced by the fact that the non-baking fuel is used Serving colloidal dispersion of slimy texture from coking coal is being prepared.

Die Ausführung des erfindungsgemäßen Verfahrens gestaltet sich z. B. in folgender Weise: Anthracitfeinkohle wird in dem Zustand, wie sie aus der Wäsche oder vom Brecher kommt, d.'h. in einer Korngröße von etwa o bis, 5 mm, verwendet. Zum Einbinden von- 8o bis 85 Teilen Anthracitfein:kohle genügt in der Regel eine Menge schleimiger Dispersion, welche etwa 2o bis 15 Teilen bakkender Feinkohle entspricht. Das Gemisch der Dispersion mit der Anthracitfeinkohle enthält etwa t o bis 15 % Wasser und ist sofort preßfähig. Die Rohbrikette gelangen, erforderlichenfalls nachentsprechender Trocknung, sofort in den Verkokungsofen; da die nach dem vorliegenden Verfahren hergestellten Brikette während der Verkokung nicht zusammenbacken, kann diese auf sehr wirtschaftliche Weise in stetig betriebenen, selbsttätig arbeitenden Öfen vorgenommen werden.The execution of the method according to the invention is such. B. in the following way: Anthracite fine coal is in the state as it comes from the laundry or from the crusher, i.e. in a grain size of about o to 5 mm, is used. To integrate of- 8o to 85 parts Anthracitfein: coal is generally sufficient amount of a slimy dispersion which corresponds to about 2o to 1 5 parts of fine coal bakkender. The mixture containing the dispersion with the Anthracitfeinkohle t o about 1 to 5% of water and is immediately preßfähig. The raw briquettes, if necessary after appropriate drying, go immediately into the coking oven; Since the briquettes produced according to the present process do not cake together during coking, this can be done in a very economical way in continuously operated, automatically operating ovens.

Es sind auch Verfahren zur Herstellung von Briketten aus einem Gemisch backender und nichtbackender Kohle bekanntgeworden. Diese Verfahren arbeiten jedoch nach ganz anderen Grundsätzen; da bei ihnen die Kohle bei weitem nicht so fein gemahlen wird, daß nach Zusatz entsprechender Wassermengen eine schleimige Dispersion entsteht, welche so viel Bindekraft besitzt, daß die Brikette ohne Anwendung übermäf.')ig hoher Drucke hergestellt werden können.There are also methods of making briquettes from a mixture Baking and non-baking coal became known. However, these methods work according to completely different principles; because with them the coal is nowhere near as finely ground becomes that after adding appropriate amounts of water a slimy dispersion is formed, Which has so much binding power that the briquette is without application overmäf. ') ig high prints can be produced.
