Description

Verfahren der Außenbeheizung eiserner Trommelentgaser. Die Feuerungsgase, die zur Außenbeheizung der drehbaren eisernen Trommel von Öfen zum Entgasen bituminöser Stoffe zwecks Gewinnung von Urteer dienen, enthalten Sauerstoff, Wasserdampf usw. Diese Bestandteile gehen bei bestimmten Temperaturen Verbindungen mit dem Eisen der Trommel ein, wodurch diese allmählich zerstört wird. Der Ersatz einer auf diese Weise unbrauchbar gewordenen Trommel durch, eine neue Trommel ist, selbst wenn eine ,solche auf Lager gehalten wird, mit einer unter Umsänden wochen-. langen Betriebsstörung verbunden.Process of external heating of iron drum degassers. The combustion gases, those for external heating of the rotating iron drum of furnaces for degassing bituminous Substances used for the extraction of primal tar contain oxygen, water vapor, etc. At certain temperatures, these components form compounds with iron the drum, gradually destroying it. The replacement one on this If a drum has become unusable, a new drum is, even if one , such is kept in stock, with a possibly weekly. long malfunction tied together.

Es ist bekannt, Gase, die zum Glühen von Metallen dienen sollen, dadurch inert zu machen, daß sie vor dem Eintritt in den Glühraum mit Spänen in Berührung ,gebracht werden, die aus -dem gleichen Metall bestehen wie die zu glühenden Gegenstände. Der Erfolg dieser Maßnahme ist in einer Ersparnis. an Arbeitsgut und, in einer Erhöhung der Ausbeute an solchem zu erblicken.It is known that gases which are to be used for annealing metals, thereby To make inert that they come into contact with chips before entering the annealing chamber , which consist of -the same metal as the objects to be glowed. The success of this measure is in a saving. in labor and, in an increase to behold the yield of such.

Dieses bekannte Verfahren zeigt nun einen Weg, wie der obenerwähnte Übelstand beseitigt oder doch stark vermindert und die eiserne Trommel haltbarer gemacht werden kann. Gemäß der Erfindung wird .der Strom der Feuerungsgase, bevor er die Trommelwandung erreicht,- mit Körpern in Berührung gebracht, die auf die Verbrennungsgase dieselbe oder eine ähnliche Wirkung wie das Eisen, der Trommel ausüben, dabei aber weniger wertvoll :und leichter zu ersetzen sind als die Trommel. Statt an der Trommel werden die Zersetzungen jetzt also an den. im Gasstrom liegenden Körpern auftreten. Als Körper der genannten Art kommen vornehmlich Eisenstücke oder -abfälle in solcher Gestalt in Frage, daß sie eine möglichst große Angriffsoberfläche darbieten, z. B. Schrott, Drehspäne, Blechstücke oder -ringe (Raschigringe), aber auch Stücke oder Abfälle von anderen Metallen, z. B. Kupfer oder Aluminium, ferner u. a. Koks. Man kann auch eine Mischung von Körpern aus verschiedenartigem Stoff verwenden. Bisweilen wird es zweckmäßig sein, Körper aus verschiedenartigem Stoff auf den Strom .der Feuerungsgase nacheinander einwirken zu lassen.This known method now shows a way like the one mentioned above Bad situation eliminated or at least greatly reduced and the iron drum more durable can be made. According to the invention, the flow of combustion gases is before he reaches the drum wall, - brought into contact with bodies on the Combustion gases have the same or a similar effect as the iron, the drum exercise, but less valuable: and easier to replace than the drum. Instead of the drum, the decompositions are now transferred to the. lying in the gas flow Bodies occur. Pieces of iron or iron are mainly used as bodies of the type mentioned -waste in such a form in question that it has the largest possible attack surface perform, e.g. B. scrap, turnings, pieces of sheet metal or rings (Raschigringe), but also pieces or waste of other metals, e.g. B. copper or aluminum, furthermore i.a. Coke. One can also use a mixture of bodies made of different types of material use. Sometimes it will be useful to have bodies made of different types of material to act on the flow of combustion gases one after the other.

Die Körper können nach Belieben über dem Boden oder an sonstigen Wandteilen des Verbrennungsraumes oder der Gasführungskanäle angebracht oder in ihnen aufgehängt sein. Um letzteres zu vermeiden, ' abergleichwohl die Angriffsfläche zu vergrößern, kann man als Gasführungskanäle eine Mehrzahl von. Rohren verwenden. Man wird die Körper zweckmäßig auswechselbar anordnen.The bodies can be above the floor or on other wall parts as desired the combustion chamber or the gas ducts attached or suspended in them be. In order to avoid the latter, 'but nevertheless to enlarge the attack surface, can be used as gas ducts a plurality of. Use pipes. One becomes the Expediently arrange the body interchangeably.
