Description

Verfahren zum Entschwelen von Kohlen und anderen Teer abgebenden Stoffen durch unmittelbare Einwirkung heißer brennbarer Gase. Bei dem durch das. Patent 35o678 geschützten Verfahren zum Entschwelen von Kohlen und anderen Teer abgebenden Stoffen durch unmittelbare Einwirkung heißer, brennbarer Gase erfolgt die Aufheizung des zum Entschwelen dienenden Gasstromes zunächst in bekannter Weise durch einen - zweckmäßig eisernen - von außen beheizten Vorwärmer und sodann durch Zumischen der Verbrennungsgase einer in den Gasstrom hineinbrennenden Heizflamme.Process for deglazing coals and other tar-releasing substances through direct exposure to hot, flammable gases. In the case of the patent 35o678 protected process for deglazing coals and other tar emitting Substances that are directly exposed to hot, flammable gases are heated up of the gas stream used for deglazing initially in a known manner through a - appropriately iron - externally heated preheater and then by mixing the combustion gases of a heating flame burning into the gas flow.

Im Dauerbetriebe wird dieses Verfahren in der Weise ausgeführt, daß ein Teil des beim Entschwelen der Kohle usw. entstehenden Gasgemisches nach erfolgter Entteerung im Kreislaufe zum Wiederaufheizen und Entschwelen benutzt wird, während der Überschuß für andere Zwecke nutzbar gemacht werden kann.In continuous operation, this process is carried out in such a way that part of the gas mixture produced when the coal is deglazed, etc. after it has taken place De-taring in the circuit for reheating and deglazing is used while the surplus can be used for other purposes.

Der auf diese Weise für andere Zwecke frei werdende Teil des umlaufenden Gasstromes besitzt den Heizwert der Schwelgase, vermindert durch die Zumischung der umlaufenden Gase, welche durch die in den Gasstrom hineinbrennende Heizflamme eine entsprechende Schwächung ihres Heizwerts erfahren.The part of the revolving that becomes free for other purposes in this way The gas flow has the calorific value of the carbonization gases, reduced by the admixture the circulating gases, which are caused by the heating flame burning into the gas flow experience a corresponding weakening of their calorific value.

In solchen Fällen, in denen neben der Gewinnung von Schwelkoks (Grude) und Teererzeugnissen besonderes Gewicht auf die Erzeugung von heizkräftigem Gas in größeren Mengen gelegt wird, als es bei dem beschriebenen Verfahren entfällt, gibt die vorliegende Erfindung ein neues Verfahren an, durch das die zweite Stufe der Aufheizung in gleich wirksamer Weise durchgeführt werden kann, während gleichzeitig ein noch höher wertiges Gas in größerer Menge gewonnen wird. Dies geschieht in der Weise, daß bei dem Verfahren gemäß dem Hauptpatent in den zum Entschwelen dienenden Gasstrom hinter dem Vorwärmer ein heißes brennbares Gas, z. B. Generatorgas aus einem genügend heiß gehenden Gaserzeuger, eingeleitet wird, das durch seine fühlbare Wärme die Temperatur des durch den Vorwärmer bereits vorerhitzten Gasstromes so weit steigert, wie dies für die Durchführung des Schwelvorganges erforderlich ist.In such cases, in which in addition to the extraction of smoldering coke (Grude) and tar products special emphasis on the production of heating gas is placed in larger quantities than is not required in the procedure described, The present invention provides a new process by which the second stage the heating can be carried out in an equally effective manner while at the same time an even higher quality gas is obtained in larger quantities. This is done in the Way that in the process according to the main patent in the serving for the deswelling Gas flow downstream of the preheater is a hot combustible gas, e.g. B. generator gas off a sufficiently hot gas generator, is initiated, which is felt by its Heat the temperature of the gas stream that has already been preheated by the preheater far increases, as is necessary for the implementation of the smoldering process.
