Durch die Innenisolation der Rohre wird erreicht, daß die Rohrwandtemperatur unter dem Ofen schnell abgebaut wird. Dadurch wird es möglich, das unter dem Ofen befindliche Sammelleitungssystem aus normalem Kohlenstoffstahl auszuführen. Für den unteren Teil der Reaktionsrohre ist vorgesehen, das Reaktionsprodukt durch ein Zentralrohr zu führen, wobei die Isolierung zwischen diesem Zentralrohr und dem Reaktionsrohr angeordnet ist. Um die Katalysatorraasse aus dem Reaktionsrohr nach unten abführen zu können, sind die Reaktionsrohre mit den Sammelleitungen über Flanschverbindungen verbunden.The invention relates to an improvement of a tubular fission furnace for the indirect heating of fissile Media, especially for the splitting of hydrocarbons for the production of synthesis gas, Town gas and hydrogen, with a plurality of vertical reaction tubes and manifolds, wherein the reaction tubes are connected at their lower end to the manifolds, the Manifolds that carry the reaction tubes, the manifolds are below the furnace floor, the collecting lines have an inner insulation, the reaction tubes at the lower end with an inner insulation are provided, which from the connection point of the manifolds to about the top of the The bottom of the furnace is sufficient and there is a pipe for the passage of the reaction gas within the insulation located, according to patent 1,542,530. The inner insulation of the pipes ensures that the pipe wall temperature breaks down quickly under the stove. This makes it possible to do this under the stove Execute the existing manifold system from normal carbon steel. For the lower part the reaction tube is provided to lead the reaction product through a central tube, wherein the Insulation is arranged between this central tube and the reaction tube. Around the catalyst terrace To be able to discharge downward from the reaction tube, the reaction tubes with the collecting lines are connected via flange connections. Soll oder kann die Katalysatormasse nach oben aus den Rohren abgesaugt werden, so ist es nicht erforderlich, zwischen den Reaktionsrohren und den Sammelleitungen Flanschverbindungen vorzusehen. Durch die Ausführung ohne Flanschverbindungen zwischen den Reaktionsrohren und den Sammelleitungen werden zahlreiche Flanschenpaare eingespart und auch die Gefahr von Undichtigkeiten durch unter Wärmespannungen verzogene Flanschenpaare vermieden. Soll bei einer derartigen Ausführung ein Reaktionsrohr zu Reparaturzwecken aus dem Ofen entfernt werden, so kann in diesem FaIi, insbesondere bei Verwendung von Kohlenstoffstahl als Verlängerung des Reaktionsrohres bzw. ab. Übergangsstück und der sich daraus ergebenden leichten Brenn- und Schweißbarkeit, das Reaktionsrohr auf einfache Weise von der Sammelleitung abgetrennt werden und anschließend durch eine auf der Baustelle leicht auszuführende Schweißnaht wieder eingesetzt werden.If the catalyst mass is to or can be sucked upwards out of the pipes, it is not necessary to to provide flange connections between the reaction tubes and the manifolds. Due to the design without flange connections between the reaction tubes and the collecting lines Numerous pairs of flanges are saved and also the risk of leaks from under Thermal stresses distorted flange pairs avoided. Should be a Reaction tube are removed from the furnace for repair purposes, so in this case, in particular when using carbon steel as an extension of the reaction tube or from. Transition piece and the resulting easy flammability and weldability, the reaction tube can easily be separated from the manifold and then by one on the construction site easy-to-perform weld seam can be reinserted. Es wurde nun gefunden, daß bei Reaktionsrohren mit einer Schweißverbindung zur Sammelleitung und mit Innenisolierung im unteren Teil Kriechströriie am äußeren Kohlenstoffstahlteil vermieden werden können, wenn das innerhalb der Isolation des Reaktionsrohres befindliche Zentralrohr bis in den Sammler hineinragt und zwischen" dem Zentralrohr und dem Reaktionsrohr in Höhe des Ofenbodens ein Abdichtungsstück angeordnet ist, welches Reaktionsrohr und Zentralrohr gasdicht miteinander verbindet.It has now been found that with reaction tubes with a welded connection to the manifold and with internal insulation in the lower part of creeping noise outer carbon steel part can be avoided if the central tube located within the insulation of the reaction tube extends into the collector protrudes and between "the central tube and the reaction tube at the level of the furnace bottom a sealing piece is arranged, which connects the reaction tube and central tube gas-tight with each other. Durch die erfindungsgemäße Ausgestaltung des Gegenstandes des Hauptpatents ist es nicht möglich, daß bei einer undichten Innenisolierung Reaktionsgase in Form von Kriechströmen an die Wand des Außenrohres bzw. Reaktionsrohr gelangen und das Außenrohr, welches aus Kohlenstoffstahl besteht, auf diese Weise unzulässig hoch erhitzt wird.Due to the inventive design of the subject matter of the main patent, it is not possible that with a leaky inner insulation reaction gases in the form of leakage currents on the wall of the Outer tube or reaction tube get and the outer tube, which consists of carbon steel, on this way it is heated to an unacceptably high level. Die Zeichnung zeigt einen Schnitt durch den unteren Teil einer beispielhaften Ausführung des Reaktionsrohres in seiner Verbindung mit der Sammelleitung. Das Ende des Reaktionsrohres 24 ist an der Stelle, an der die erhöhten Rohrwandtemperaturen infolge Wärmeableitung abgebaut sind, durch eine Schweißnaht (30) mit dem Rohrstück 31, das aus normalem Kohlenstoffstahl besteht, verbunden. Der unier dem Ofenboden 21 befindliche Teil des Reaktionsrohres ist mit der Innenisolierung 27 versehen, die sich zwischen dem -Zentralrohr 26 und dem Ende des Reaktionsrohres 24 befindet. Das Zentralrohr 26 ist über das konische Abdichtungsstück 32 durch eine Schweißnaht dicht mit dem Reaktionsrohr verbunden. Über dem konischen Abdichtungsstück liegt ein Katalys&torrost 33 auf. Der Katalysatorrost dient als Tragvorrichtung für die im Reaktionsrohr befindliche Katalysatormasse.The drawing shows a section through the lower part of an exemplary embodiment of the reaction tube in its connection with the manifold. The end of the reaction tube 24 is at the Point at which the increased pipe wall temperatures as a result of heat dissipation are reduced by a Weld seam (30) connected to the pipe section 31, which consists of normal carbon steel. Of the The part of the reaction tube located on the furnace bottom 21 is provided with the inner insulation 27, which is located between the central tube 26 and the end of the reaction tube 24. The central tube 26 is tightly connected to the reaction tube via the conical sealing piece 32 by a weld seam. Lies over the conical sealing piece a catalyst grate 33. The catalyst grate serves as a support device for the one located in the reaction tube Catalyst mass. Hierzu 1 Blatt Zeichnungen1 sheet of drawings
