Es ist bekannt, daß sich in der Regel für die Brikettierung nur solche Steinkohlen eignen, deren Gehalt an flüchtigen Bestandteilen unter 14% liegt. Es sind deshalb von den zur Verfügung stehenden Steinkohlen von Natur aus lediglich Anthrazit sowie Mager- und Eßkohlen für die Brikettierung geeignet. Hierdurch ist aber die Kohlenbasis für die Brikettierung sehr beschränkt.It is known that, as a rule, only those hard coals are suitable for briquetting whose content of volatile components is below 14%. It is therefore from the available hard coal Naturally only anthracite as well as lean and edible coals suitable for briquetting. As a result, however, the carbon base for briquetting is very limited.
Es hat deshalb bisher nicht an Versuchen gefehlt, auch Steinkohlen mit einem höheren Gehalt an flüchtigen Bestandteilen beispielsweise durch eine vorhergehende Schwelung, bei der ein Halbkoks mit höchstens bis zu etwa 100/o flüchtigen Bestandteilen anfällt, für eine Brikettierung brauchbar zu machen. So ist es bekannt, mehr als 4O°/o Fettfeinkohlen mit weniger als 60 Vo Magerfeinkohlen zu mischen und diese Mischung nach einer Wärmebehandlung zwischen etwa 400 und 1000° C, bei der die Halbverkokung der Fettfeinkohle erreicht wird, zu brikettieren. Es ist außerdem bekannt, den aus höherflüchtigen Steinkohlen gewonnenen Halbkoks als Magerungsmittel einer Brikettierfeinkohle in der gewünschten Menge zuzusetzen.There has therefore been no lack of attempts to make coal with a higher content of volatile constituents, for example by a previous carbonization, in which a char with a maximum is obtained up to about 10 0 / o volatiles for briquetting useful. It is known to mix more than 40% fine coal with less than 60% by volume of lean coal and to briquette this mixture after a heat treatment between about 400 and 1000 ° C., at which the semi-coking of the fine coal is achieved. It is also known to add the semi-coke obtained from more volatile hard coals as a lean agent to a briquetting fine coal in the desired amount.
Es ist weiterhin bekannt, heißen Schwelkoks einer Brikettierkohle zuzumischen und das Gemisch einer Heißbrikettierung bei Temperaturen von 300 bis 45O0C zu unterwerfen. Hierbei wird der heiße Schwelkoks einer Feinkohle mit einem Gehalt an flüchtigen Bestandteilen unter 14fl/o zugemischt, die jedoch zum Zeitpunkt der Mischung mit dem heißen Schwelkoks völlig trocken sein soll. Nasse Feinkohlen sind demnach vor der Mischung mit dem heißen Schwelkoks weitgehend zu trocknen, damit bei der anschließenden Heißbrikettierung die erforderlichen Temperaturen von 300 bis 450° C erzielt werden.It is further known, to admix a hot coke Brikettierkohle and subjecting the mixture to a hot briquetting at temperatures of 300 to 45O 0 C. Here, the hot low-temperature coke is mixed with a fine coal with a volatile content of less than 14 fl / o, which, however, should be completely dry at the time of mixing with the hot low-temperature coke. Wet coals must therefore be largely dried before being mixed with the hot low-temperature coke so that the required temperatures of 300 to 450 ° C can be achieved during the subsequent hot briquetting.
Als Schwelverfahren haben sich insbesondere solche Verfahren als geeignet erwiesen, die von einer höherflüchtigen Steinkohle ausgehen und feinkörnigen Schwelkoks in der Wirbelschicht oder in der Flugstaubwolke herstellen. Diese Schwelverfahren haben jedoch den Nachteil, daß bisher die fühlbare Wärme des Schwelkokses, die zurückzugewinnen im allgemeinen nur schwer möglich ist, völlig ungenutzt verlorenging.Processes that have proven to be particularly suitable as smoldering processes are those that are carried out by a run out of more volatile hard coal and fine-grained smoldering coke in the fluidized bed or in the Create a cloud of airborne dust. However, these smoldering methods have the disadvantage that so far the tactile Heat from the low-temperature coke, which can generally only be recovered with difficulty, is completely unused got lost.
Es wurde nun gefunden, daß man unter wesentlich günstigeren Bedingungen eine Brikettierkohlenmischung
aus im heißen Gasstrom geschwelten und nicht vorerhitzten, jedoch getrockneten Steinkohlen
herstellen kann, wenn der heiße Schwelkoks einer feuchten Brikettierfeinkohle mit einem Wassergehalt
bis zu etwa 30%, vorzugsweise von etwa 20 bis 25°/», Verfahren zur Herstellung einer
BrikettierkohlenmischungIt has now been found that, under significantly more favorable conditions, a briquetting coal mixture can be produced from coal that has been carbonized in the hot gas stream and not preheated but dried if the hot carbonized coke is a moist briquetting fine coal with a water content of up to about 30%, preferably from about 20 to 25% ° / », method of making a
Briquetting charcoal mixture

zu deren Trocknung und Aufheizung auf Brikettiertemperatur zugemischt wird.for their drying and heating to briquetting temperature is added.
Auf diese Weise kann auch aus einer Steinkohle mit höherem Gehalt an flüchtigen Bestandteilen eine Brikettierkohlenmischung hergestellt werden, indem man eine solche Feinkohle schwelt und den Schwelkoks nach der Trennung von den gasförmigen Schwelprodukten unmittelbar in heißem Zustand einer nassen Brikettierfeinkohle in einer solchen Menge zumischt, daß die Temperatur, der Wassergehalt und der Gehalt an flüchtigen Bestandteilen der Brikettiermischung in den für eine Brikettierung geeigneten Grenzen liegt.In this way, hard coal with a higher content of volatile components can also be converted into a Briquetting coal mixture can be produced by smoldering such a fine coal and the smoldering coke immediately after separation from the gaseous carbonization products in the hot state to a wet briquetting fine coal in such an amount that the temperature, the water content and the volatile content of the briquetting mixture in those for briquetting suitable limits.
Nach einer anderen Ausführungsform des erfindungsgemäßen Verfahrens wird die zum Brikettieren vorgesehene Feinkohle mit hohem Gehalt an flüchtigen Bestandteilen in zwei Mengenteilströme aufgeteilt, wobei ein Teilstrom der Schwelung unterworfen und der heiße Schwelkoks dem anderen Teilstrom unmittelbar zugemischt wird. Die fühlbare Wärme des ersten Teilstromes reicht dann aus, den zweiten Teilstrom zu trocknen und auf die für die Brikettierung gewünschte Temperatur zu bringen.According to another embodiment of the method according to the invention, this is used for briquetting The intended fine coal with a high content of volatile constituents is divided into two partial flows, whereby one part of the stream is subjected to carbonization and the hot coke is subjected to the other part of the stream is added immediately. The sensible heat of the first partial flow is then sufficient for the to dry the second partial stream and bring it to the temperature desired for the briquetting.
Der entscheidende Vorteil des erfindungsgemäßen Verfahrens liegt in der günstigen Wärmewirtschaft. Die fühlbare Wärme des Schwelkokses wird beim erfindungsgemäßen Verfahren in vollem Umfang ausgenutzt, um die Vortrocknung und Vorwärmung der Brikettiermischung durchzuführen. Deshalb sind beim Verfahren der Erfindung die bisher notwendigen besonderen Apparate für die Trocknung und Vorwärmung der Brikettiermischung nicht erforderlich. The decisive advantage of the method according to the invention lies in the favorable heat economy. The sensible heat of the smoldering coke is fully utilized in the process according to the invention, to carry out the pre-drying and preheating of the briquetting mix. That's why in the process of the invention, the special apparatus previously necessary for drying and It is not necessary to preheat the briquetting mix.
Die Entgasung der höherflüchtigen Steinkohlen erfolgt vorzugsweise bei einer Endtemperatur desThe more volatile hard coals are preferably degassed at a final temperature of the
