Description

Die Erfindung betrifft Dampferzeuger beliebiger Bauart mit Überhitzung des erzeugten Dampfes und hat eine besonders zweckmäßige Schaltung der Überhitzerrohre zum Gegenstand, durch welche es ermöglicht wird, überhitzten Dampf von völlig gleichmäßiger .Temperatur dem Kessel bzw. dem Dampf@ustrittssammler des Kessels zu entnehmen.The invention relates to steam generators of any type with overheating of the generated steam and has a particularly useful circuit of the superheater tubes to the subject, through which it is made possible to have superheated steam of completely uniform .Temperature can be taken from the boiler or the boiler's steam outlet collector.

Bei der bisher fast allgemein üblichen Überhitzerbauart wurde der von der Dampftrommel oder einem Zwischensammler kommende Dampf durch eine Reihe von parallel nebeneinander im Rauchgasstrom liegenden Rohrschlangen geleitet, durch die Rauchgaswärme überhitzt und in einem Austrittssammler aulfgefangen, von wo derselbe der Verwendungsstelle zugeführt wurde..-Diese Schaltung hatte aber den Nachteil, daß in den Austrittssammler, `über seine Länge gesehen, Dampf von verschiedener Temperatur einströmte. Während die seitlich gelegenen Rohre infolge Randabkühlung Dampf niedrigerer Temperatur lieferten, führten die in der Mitte gelegenen Rohre höher überhitzten Dampf, der sich mit dem anderen Dampf teilweise nur unvollkommen mischte und dadurch störende Schwankungen der Dampfendtemperatur verursachte.The Steam coming from the steam drum or an intermediate collector through a series by coils lying parallel to each other in the flue gas flow the flue gas heat is overheated and trapped in an outlet collector, from where it is was supplied to the point of use ..- But this circuit had the disadvantage that in the outlet collector, `seen along its length, steam of various types Temperature flowed in. While the laterally located pipes due to edge cooling The pipes in the middle led to the supply of steam at a lower temperature higher superheated steam, which is partially incomplete with the other steam mixed and thereby caused disruptive fluctuations in the final steam temperature.

Um diese- Mischung inniger zu gestalten und damit eine gleichmäßigere Temperatur des austretenden Dampfes zu erreichen, wird mit der Erfindung vorgeschlagen, die Austrittsenden der Rohrschlangen von der dem Austrittssammler gegenüberliegen-. den Seite nebeneinander in zwei Gruppen zu unterteilen und. kreuzweise so zu führen, daß die Rohre jeder Gruppe in den Austrittssammler aurf seiner ganzen Länge einmünden, wobei sich die Rohrenden beider Gruppen der Reihe nach abwechseln,, so daß die innen im Rohrbündel liegenden Schlangen ihren heißeren Dampf in die Enden des Austrittssammlers einströmen lassen, während die außenliegenden Schlangen ihren kälteren Dampf mehr an den Mittelteil des Sammlers abgeben. Ein Beispiel der Anordnung gemäß der Erfindung ist in der Zeichnung schematisch dargestellt, und zwar zeigt Abb. z einen gemäß der Erfindung ausgestalteten -Überhitzer, von der Seite gesehen, und Abb. 2 eine Draufsicht auf den Gegenstand der Abb. i in Sicht von A.To make this mixture more intimate and thus a more even one To achieve the temperature of the exiting steam is proposed with the invention, the exit ends of the coils opposite the exit header. to divide the page side by side into two groups and. to lead crosswise that the pipes of each group flow into the outlet header along its entire length, whereby the pipe ends of both groups alternate one after the other, so that the inside Snakes lying in the tube bundle send their hotter steam to the ends of the outlet header let in while the outlying snakes their colder steam more submit to the central part of the collector. An example of the arrangement according to the invention is shown schematically in the drawing, namely Fig. Z shows one according to of the invention designed superheater, seen from the side, and Fig. 2 a Top view of the object of Fig. I as seen from A.

Der von der Trommel oder dem Zwischen-Sammler i kommende Dampf strömt durch die parallel nebeneinander im Rauchgaskanal2 liegenden Rohrschlangen 3 bis z1= Austrittsende 4, das seine parallele Lage verläßt, wie z. B. das Rohr 5 von der Mitte des Rohrbündels zum rechten Ende des Austrittssammlers 6 führt, während das in der Mitte daneben liegende Rohr 7 zum linken Ende des Sammlers über Kreuz geleitet ist.The steam coming from the drum or the intermediate collector i flows by the coils 3 to 3 lying parallel to each other in the flue gas duct 2 z1 = exit end 4, which leaves its parallel position, such as. B. the tube 5 of the middle of the tube bundle leads to the right end of the outlet header 6, while the pipe 7 lying next to it in the middle to the left end of the collector crosswise is directed.

Wie Abb. 2 erkennen läßt, kreuzen die Austrittsenden 4 der linken Rohrgruppe die der rechten Rohrgruppe, wobei sie auch abwechselnd in den Austrittssammler 6 einmünden.As can be seen in Fig. 2, the exit ends 4 cross the left Tube group those of the right tube group, whereby they also alternate in the outlet header 6 merge.
