Description
Verfahren zur Regelung des Abkühlvorganges im Tunnelofen Die Erfindung bezieht sich allgemein auf Tunnelöfen, wie sie i11 den letzten Jahren insbesondere in der keramischen Industrie eine sehr weitgehende Verbreitung gefunden haben, und ist vorzugsweise anwendbar auf gasbefeuerte Tunnelöfen, bei denen das Gas bzw. die Gas-Luft--AIischung nicht unter dem Einruß des Schornsteinzuges iii das Ofeninnere gelangt bzw. aus den Düsen ausströmt, sondern unter einem gewissen Gasdruck.Method for controlling the cooling process in the tunnel furnace The invention generally refers to tunnel ovens, such as those used in i11 in recent years in particular have found widespread use in the ceramics industry, and is preferably applicable to gas-fired tunnel ovens in which the gas or the Gas-air mixture not under the influence of the chimney draft iii the inside of the stove reaches or flows out of the nozzles, but under a certain gas pressure.
Erfindungsgemäß soll bei solchen Tunnelöfen eine vorzügliche Wärmeausnutzung und Beherrschung der gesamten Temperaturverhältnisse in der Kühlzone in sehr einfacher und vorzüglich einstellbarer Weise erreicht werden.According to the invention, excellent heat utilization should be achieved in such tunnel ovens and control of the entire temperature conditions in the cooling zone in a very simple way and can be achieved in an excellent adjustable manner.
Zu diesem Zweck wird in der Kühlzone in _ bekannter Weise die ganze Innenfläche des Ofenquerschnitts mit waagerecht. unter Umständen auch unter einem Winkel zur Ofena c -hse verlegten b Rohren aus temperaturwiderstandsfähigem"zweckmäßigkeramischeinWerkstoff ausgekleidet, und ' zwar in der Weise, daß eine große Anzahl solcher Rohre so übereinander verlegt werden, daß wenigstens die Seitenwandungen, gegebenenfalls auch die gewölbte oder scheitrechte Decke davon im wesentlichen bedeckt sind. Von diesen Rohren kann ein Teil unmittelbar nach der Vor,-_ wärmzone durchgeführt werden, während man einen änaeren Teil der Rohre zur Heranführung der vorgewärmten Luft zu den Brennern in an sich bekannter Weise benutzt. \-Ian ordnet diese Rohre zweckmäßig in Gruppen an, und zwar so, daß man jeweils eine beliebige Anzahl der Rohre durch geeignete Regelglieder, vorzugsweise gewöhnliche Schieber, an- oder abschalten kann und ebenso die Rohrleitungen bzw. Rohrleitungsgruppen wahlweise für die Zuführung von vorgewärmter Luft zu den Brennern oder zur Versorgung des Abkühlendes benutzt. Ferner werden erfindungsgemäß diese Rohrleitungsgruppen so angeordnet und ausgebildet, daß man wahlweise durch sie bzw. durch einzelne Abschnitte von ihnen nicht Luft, sondern Kühlwasser hindurchführt, das man dann vorge@väriiit fair andere Zwecke verwenden kann.For this purpose, in the known manner, the whole Inner surface of the furnace cross-section with horizontal. possibly also under one At an angle to the furnace a c -hse, b pipes made of temperature-resistant "functional ceramic-in material" were laid lined in such a way that a large number of such tubes are so superimposed be laid that at least the side walls, possibly also the arched or a log ceiling are essentially covered by it. From these pipes can a part can be carried out immediately after the pre-, -_ warming zone while one Another part of the pipes for bringing the preheated air to the burners in used in a known manner. \ -Ian arranges these pipes appropriately in groups on, in such a way that any number of tubes through suitable Control elements, preferably ordinary slides, can switch on or off and likewise the pipes or pipe groups optionally for the supply of preheated Air is used to the burners or to supply the cooling end. Further be according to the invention these pipeline groups are arranged and designed so that one optionally through them or through individual sections of them, not air, but Cooling water passes through, which can then be used for other purposes can.
Durch diese vollständige Auskleidung des Ofenkanalinnern llil abkühlende mit Rohrleitungen, die wäliliveise von einem gasförmigen oder von einem Müssigen Kühlmittel ganz oder nur abschnittsweise umspült werden können, wird eine nahezu restlose Beherrschung der Temperaturverhältnisse an jeder Stelle des elbkühlendes sowie eine sehr weitgehende Ausnutzung des Wärmeinhalts der Abkühlzone und eine Beschleunigung des Kühlvorganges, ohne das Brenngut zu gefährden, wie dies bei unmittelbarer Entnahme der Gase aus dem Abkühlende der Fall ist, erzielt. Man kann in den Teilen der Abkühlzone, in denen eine schärfere Kühlung möglich ist, mit Wasser, in den anderen mit Luft kühlen und die gewonnene Altwärme in beliebiger Weise ausnutzen.Through this complete lining of the furnace duct interior llil cooling with pipelines that sometimes come from a gaseous or from an idle Coolant can be completely or only partially flushed around, becomes an almost complete control of the temperature conditions at every point of the elbe cooling as well as a very extensive utilization of the heat content of the cooling zone and a Acceleration of the cooling process without endangering the material to be fired, as is the case with immediate Removal of the gases from the cooling end is achieved. One can in parts the cooling zone, in which a sharper cooling is possible, with water, in the Cool others with air and use the recovered heat in any way.
Die Förderung des Kühlmittels durch die Rohre kann in bekannter Weise durch die Injektonvzrkung des Druckgases, durch ein Gebläse, eine Pumpe o. dgl. erfolgen.The conveyance of the coolant through the tubes can be carried out in a known manner by injecting the compressed gas, by a fan, a pump or the like. take place.
In der Zeichnung ist eine grundsätzliche Ausführungsform der Erfindung dargestellt. Die Rohre, deren Querschnitt zweckmäßig rund, gegebenenfalls aber auch viereckig oder vieleckig sein kann - besonders seien noch sechseckige Rohre mit @vabenförndger Anordnung genannt - können sowohl unmittelbar der Ofenwand anliegend wie teilweise, etwa zur Hälfte ihres Umfanges, in sie versenkt, wie vollkommen freiliegend angeordnet werden.In the drawing is a basic embodiment of the invention shown. The tubes, whose cross-section is expediently round, but possibly also can be square or polygonal - especially hexagonal tubes are also included @ vabenförndger arrangement called - can be directly adjacent to the furnace wall how partially, about half of its circumference, sunk into it, how completely exposed to be ordered.
Die Anwendung der Erfindung ist nicht auf gasbefeuerte Tunnelöfen beschränkt, sondern ebenso auch bei mit festen oder flüssigen Brennstoffen oder elektrisch beheizten möglich.The application of the invention is not to gas-fired tunnel kilns limited, but also with solid or liquid fuels or electrically heated possible.
