Description

Wärmestrahlungskörper für Flammrohre von Dampfkesseln. Bei Dampfkesseln mit Wasser- oder Heizröhren hat man bereits in die Heizzüge zwischen den Röhren aus Schamotte bestehende, in Richtung des Gasstromes sich erstreckende Wände eingebaut, durch welche die Hitze der in mehrere Teilströme zerlegten Heizgase aufgespeichert und die aufgespeicherte Wärme an die gegenüberliegenden Rahrflächen rückgestrahlt werden soll.Heat radiation body for flame tubes of steam boilers. With steam boilers with water or heating pipes you have already got into the heating flues between the pipes walls made of chamotte and extending in the direction of the gas flow are built in, through which the heat of the heating gases broken down into several partial flows is stored and the accumulated heat is reflected back to the opposite surfaces shall be.

Die Erfindung zielt darauf hin, einen in seiner Form äußerst einfachen und verhältnismäßig leichten Wärmestrahlungskörper zu schaffen, der billig hergestellt und in vorhandene Flammrohrkessel nachträglich ohne große Mühe und Kosten eingebaut werden kann.The invention aims to be an extremely simple one in its form and to provide relatively lightweight heat radiating bodies that are inexpensively manufactured and retrofitted in existing flame tube boilers without great effort and expense can be.

Der Erfindungsgegenstand ist in einer Ausführungsform in der Zeichnung dargestellt, und zwar zeigt .The subject matter of the invention is shown in one embodiment in the drawing shown, namely shows.

Abb. I einen Querschnitt senkrecht durch einen Einflammrohrkessel mit dem neuen Einbaukörper, und Abb. 2 einen dazugehörigen, wagerechten Querschnitt nach Linie A-B der Abb. I.Fig. I a vertical cross-section through a single-flame tube boiler with the new installation body, and Fig. 2 a corresponding, horizontal cross-section according to line A-B of Fig. I.

Der Einbaukörper besteht aus einer in der Mittelebene des Flammrohres b senkrecht errichteten Wand a, die aus wärmespeichernder, feuerfester Masse gebildet ist.The installation body consists of one in the center plane of the flame tube b vertically erected wall a, which is formed from heat-storing, refractory mass is.

Die feuerfeste Wand a ruht mit ihrem zweckmäßig verbreiterten Fuß auf dem Boden des Flammrohres b auf und reicht in dem vorliegenden Fall bis nahe an dessen oberen Scheitel heran, das Flammrohr so in zwei annähernd gleich große Längszellen c und d unterteilend.The refractory wall a rests with its appropriately widened foot on the bottom of the flame tube b and extends in the present case to close Approach its upper apex, the flame tube so in two approximately equal sizes Dividing longitudinal cells c and d.

Die feuerfeste Wand a wird durch die vorbeistreichenden, in zwei Ströme zerlegten Feuergase beim Betriebe des Kessels hocherhitzt, sie strahlt Wärme gegen die Wände des Flammrohres, und es tritt in den beiden Zellen c und d folgender Vorgang ein: Die zunächst mit den wassergekühlten Flammrohrwänden in Berührung gekommenen Heizgase werden abgekühlt und wollen daher zu Boden sinken. Die an der hocherhitzten Wanda vorbeistreichenden Heizgase werden dagegen nicht abgekühlt. Es entsteht auf diese Weise eine kreisende Bewegung der Heizgase im Sinne der in Abb. I eingezeichneten Pfeile. Hierdurch findet ein vollkommener Wärmeübergang aus den Heizgasen in die Flammrohrwand statt. Diese Heizwirkung wird noch durch die vom Strahlungskörper a ausgestrahlte Wärme erhöht.The refractory wall a is made by the passing, in two streams decomposed fire gases are highly heated when the boiler is in operation; it radiates heat against it the walls of the flame tube, and the following process occurs in cells c and d a: Those that initially came into contact with the water-cooled flame tube walls Heating gases are cooled and therefore want to sink to the ground. The one on the highly heated Wanda passing hot gases, however, are not cooled down. It arises on this way a circular movement of the heating gases in the sense of the one shown in fig Arrows. This results in a complete heat transfer from the heating gases to the Flame tube wall instead. This heating effect is enhanced by that of the radiant body a radiated heat increases.

Selbstverständlich kann die Strahlungsplatte gemäß der Erfindung auch eine andere als die dargestellte Gestalt aufweisen. Beispielsweise kann sie höher oder niedriger ausgestaltet sein und auf ihrer Oberfläche kleine Wellen oder warzenartige Erhöhungen besitzen.Of course, the radiation plate according to the invention can also have a different shape than that shown. For example, it can be higher or be designed lower and on their surface small waves or wart-like Own increases.
