Description

Rekuperator mit senkrechten, durch Säulen senkrechter Hohlsteine gebildeten Rekuperatorräumen Zusatz zum Patent 854 943 Gegenstand des Patents 854 943 ist ein Rekuperator für waagerechte Koksöfen, dessen senkrechte Hohlräume durch Säulen senkrechter Hohlsteine gebildet werden. Das wesentliche Merkmal dieses Rekuperators besteht darin, daß jeder Hohlstein eine Mehrzahl von Kanälen ellipsenförmigen Querschnitts enthält und gegen die benachbarten Hohlsteine in den waagerechten Abschlußflächen durch umlaufende Nut und Feder abgedichtet ist. Vorzugsweise erfolgt die Abdichtung der Hohlsteine in oberen und unteren Vorsprüngen oder Randleisten, durch die gleichzeitig ein abwechselnd verengter und erweiterter Querschnitt der Durchflußkanäle der gegenläufig durch den, Rekuperator geführten Medien gegeben ist: Praktische Betriebserfahrungen haben ergeben, daß der Rekuperator nach dem Hauptpatent einen wesentlich höheren Wirkungsgrad in bezug auf den Wärmeaustausch zwischen den gegenläufig geführten Medien, den heißen Abgasen einerseits und den aufzuwärmenden Medien, wie Luft oder Schwachgas, andererseits besitzt als die früher bekannten Rekuperatoren. Außerdem ist auch seine Dichtigkeit gegenüber Gasübertritten aus den unter höherem Druck stehenden Hohlräumen in benachbarte, unter geringerem Druck stehende Räume ungewöhnlich groß. Infolge dieser vorzüglichen Eigenschaften eignet sich der Rekuperator nach dem Hauptpatent nicht nur für waagerechte Koksöfen, sondern erfindungsgemäß ganz allgemein für rekuperativ beheizte Industrieöfen aller Art. Als besonders wichtige Anwendungsgebiete seien Gaserzeugungsöfen mit senkrechten oder schrägen Kammern, Glasschmelz- und metallurgische COfen sowie Winderhitzer für Hoch- und Kupölöfen herausgegriffen.Recuperator with vertical hollow stones formed by vertical hollow stones Recuperator rooms Addition to patent 854 943 The subject of patent 854 943 is a Recuperator for horizontal coke ovens, the vertical cavities of which are made more vertical by columns Hollow stones are formed. The main feature of this recuperator is there in that each hollow stone has a plurality of channels of elliptical cross-section contains and against the neighboring hollow stones in the horizontal end surfaces is sealed by circumferential tongue and groove. The sealing is preferably carried out of the hollow stones in upper and lower projections or edge strips, through which at the same time an alternately narrowed and widened cross-section of the flow channels in the opposite direction is given by the recuperator-led media: Practical operating experience have shown that the recuperator according to the main patent is much higher Efficiency in terms of heat exchange between the opposing ones Media, the hot exhaust gases on the one hand and the media to be heated up, such as air or Lean gas, on the other hand, possesses than the previously known recuperators. aside from that is also its tightness against gas leaks from the under higher Pressurized cavities in neighboring, less pressurized rooms unusually large. As a result of these excellent properties, the recuperator is suitable according to the main patent not only for horizontal coke ovens, but according to the invention in general for recuperatively heated industrial furnaces of all kinds. As particularly important Areas of application are gas generating furnaces with vertical or inclined chambers, Glass melting and metallurgical furnaces as well as blast heaters for blast furnaces and copper furnaces singled out.
