Description

Verfahren zur Herstellung von Wassergas aus Kohlenstaub und Wasserdampf Bei der Herstellung von Wassergas aus Staubkohle und Wasserdampf wird entweder der Wasserdampf allein, zweckmäßig aber der Wasserdampf vermischt mit schon erzeugtem Wassergas in Regeneratoren auf die nötige Reaktionstemperatur gebracht. Hierauf wird dieses Gemisch einem Reaktionsraum zugeführt, wo ihm Staubkohle zugesetzt wird und wo dann die Wassergaserzeugung stattfindet. Entsprechend der Reaktionsdauer und dem zugesetzten Material muß dieser Reaktionsraum eine gewisse Länge haben. Die Erfindung schlägt nun vor, diesem Reaktionsraum nicht nur an seinem Anfang, sondern vom Anfang des Raumes fortschreitend gegen das Ende dauernd hocherhitztes Wassergas zuzusetzen. Dieser Zusatz braucht sich nicht auf die Gesamtlänge des Reaktionsraumes zu erstrecken, sondern muß den jeweiligen Betriebsbedingungen angepaßt werden.Process for the production of water gas from coal dust and water vapor In the production of water gas from pulverized coal and water vapor, either the Water vapor alone, but expediently the water vapor mixed with that which has already been generated Bring water gas to the necessary reaction temperature in regenerators. On that this mixture is fed to a reaction chamber, where dust coal is added to it and where then the water gas generation takes place. According to the reaction time and the added material, this reaction space must have a certain length. The invention now proposes that this reaction space not only at its beginning, but from the beginning of the room progressing towards the end, something that is constantly heated to a high temperature Add water gas. This addition does not need to affect the total length of the reaction space to extend, but must be adapted to the respective operating conditions.

Durch diese Maßnahme ergeben sich eine Reihe von Vorteilen. Wird z. B. der Kohlenstaub nicht mit derselben Temperatur eingeführt wie das hocherhitzte Gas, so verbraucht die Aufheizung des Brennstoffes eine Wärmemenge, die dem Reaktionsvorgang entzogen wird. Soll nun aber eine kräftige Reaktion zustande kommen, so ist man genötigt, die Anfangstemperatur des Gas- und Wasserdampfstromes heraufzusetzen. Ebenso wird wegen des Sinkens der Temperatur durch den Wärmeverbrauch der Wassergasreaktion die Reaktionsgeschwindigkeit, je weiter das Gas den Raum durchstrichen hat, immer träger; des weiteren ist es so möglich, die entstandenen Abstrahlungsverluste zu decken.This measure results in a number of advantages. Is z. B. the coal dust is not introduced at the same temperature as the highly heated Gas, the heating of the fuel consumes an amount of heat that the reaction process is withdrawn. But if a strong reaction is to come about, then one is forced to raise the initial temperature of the gas and water vapor flow. Also, because of the decrease in temperature due to the consumption of heat, the water gas reaction the rate of reaction, the further the gas has passed through space, always carrier; it is also possible to compensate for the resulting radiation losses cover.

Das Verfahren ermöglicht also eine schnellere Zersetzung, größere Leistung und eine bessere Gaszusammensetzung bei der Wassergasherstellung.The process thus enables faster, greater decomposition Performance and better gas composition in water gas production.

Eine örtliche und zeitliche Regelung der Wärmezufuhr kann ohne weiteres vorgenommen werden.A local and temporal regulation of the heat supply can easily be made.
