Description
Verfahren zum Vergasen von Steinkohlen Bekanntlich ist es sehr schwierig, Steinkohlenstaub in Gaserzeugern durchzusetzen. In Gaserzeugern gewährt Staub den Gasen nicht genügend Durchlaß. Bei backenden Steinkohlen ist außerdem die Gefahr des Hängens vorhanden. Es ist nun versucht worden, dadurch aus dem Staube ein festes Gut zu erzielen, daß man den Staub vor dem Vergasen brikettierte. Die hierzuverwendeten organischen Bindemittel, wie beispielsweise Pech, stellen aber infolge ihres hohen Preises die Wirtschaftlichkeit des Verfahrens in Frage. Versuche, die Kohlen bei gewöhnlicher Temperatur ohne Zusatz von Bindemittel zu brikettieren und dann zu vergasen, hatten nur teilweise Erfolg. Erstens sind die Briketts nur durch einen sehr hohen Druck so fest zu bekommen, daß sie das Einfüllen in die Gaserzeuger vertragen, zweitens geben aber nur backende Steinkohlen, die man vorziehen wird, bei hoher Temperatur zu verkoken, ein festes Gut. Bei nicht backenden Steinkohlen ist dieses so locker, daß es beim leisesten Druck zerfällt.Process for gasifying hard coal It is well known that it is very difficult Enforce coal dust in gas generators. In gas generators, dust grants that Gas not enough passage. There is also a risk with baking hard coals of hanging present. An attempt has now been made to get a solid one out of the dust Good thing to do is to briquette the dust before gassing. The ones used for this purpose organic binders, such as pitch, are due to their high Price the economics of the process in question. Try the coals at Briquetting at ordinary temperature without the addition of binding agents and then closed gassed, had only partial success. First, the briquettes are only by one to get very high pressure so tight that they can tolerate filling into the gas generator, Secondly, there are only baking coal, which one will prefer, at a higher level Coke temperature, a solid good. This is the case with non-baking hard coals so loose that it disintegrates at the slightest pressure.
Nach der Erfindung soll eine Steinkohle in der Weise vergast werden, daß nach dem Verfahren der Patente 455 015 und 458 247 bei erhöhten Temperaturen ohne Zusatz fremder Bindemittel in Anwesenheit der Schwelgase brikettierte Feinkohle in Brikettform unmittelbar, also noch heiß im Gaserzeuger durchgesetzt wird. Die Brikette werden mit der Temperatur, mit der sie aus der Presse kommen (etwa 35o bis 36o°) dem Gaserzeuger zugeführt. Die Kohle wird auf diese Weise in zwei Stufen erwärmt, erst in der Presse auf 35o°, dann im Gaserzeuger auf Vergasungstemperatur. Hierdurch wird der Wärmebedarf des Gaserzeugers bedeutend herabgesetzt, da nur diejenige Wärme zugeführt werden muß, die für den eigentlichen Vergasungsprozeß notwendig ist. Der unproduktive Wärmeverbrauch für das Trocknen und das Erwärmen auf 35o° fällt fort.According to the invention, a hard coal is to be gasified in such a way that according to the method of patents 455 015 and 458 247 at elevated temperatures without the addition of foreign binders in the presence of the carbonization gases, briquetted fine coal in briquette form is immediately enforced, i.e. still hot in the gas generator. The briquettes are fed to the gas generator at the temperature at which they come out of the press (approx. 35o to 36o °). The coal is heated in this way in two stages, first in the press to 35o °, then in the gas generator to gasification temperature. This significantly reduces the heat requirement of the gas generator, since only that heat has to be supplied which is necessary for the actual gasification process. The unproductive heat consumption for drying and heating to 35o ° is eliminated.
Außerdem werden die Gase heizwertreicher, da sie nicht die Kohlensäuremengen enthalten, die von der Kohle im Laufe des Brikettierprozesses abgegeben werden. Die Ausbeute an Teer wird durch das Verfahren nicht erniedrigt.In addition, the gases have a higher calorific value because they do not have the carbon dioxide levels that are given off by the coal in the course of the briquetting process. The tar yield is not reduced by the process.
