Description

Befestigung für Vorwärmer- und Überhitzerglieder, die aus einzelnen Röhrengruppen bestehen. Den Gegenstand der Erfindung bildet eine neue Befestigung für Vorwärmer- und Überhitzerglieder, die als einzelne Röhrengruppen gestaltet sind, bei welcher die nebeneinanderliegenden Eintritts- und AustrittsrÖhrenenden benachbarter Glieder je durch eine Überwurfhaube verbunden sind. Die Erfindung besteht darin, daß die beiden Röhrenköpfe eines Gliedes von einer sie umschließenden federnd nachgiebigen Blechplatte gehalten sind. Hierdurch wird erreicht, daß die Röhrenköpfe bei Bewegungen der Röhren infolge von Temperatureinwirkungen Federn folgen können, so daß die Befestigung nicht gelockert wird und Undichtigkeiten nicht entstehen.Attachment for preheater and superheater elements, which consist of individual Tube groups exist. The subject of the invention is a new attachment for preheater and superheater elements that are designed as individual tube groups, in which the adjoining inlet and outlet tube ends are adjacent Links are each connected by a cap. The invention consists in that the two tube heads of a member are resiliently yielding from an enclosing one Metal plate are held. This ensures that the tube heads when moving springs can follow the tubes as a result of the effects of temperature, so that the fastening is not loosened and leaks do not arise.

Auf der Zeichnung ist die Erfindung in einer Ausführungsform dargestellt, und zwar zeigen Fig. i bis 3 die neue Befestigung in Vorderansicht, einem Längs- und einem Querschnitt.In the drawing, the invention is shown in one embodiment, namely, Fig. i to 3 show the new attachment in a front view, a longitudinal and a cross section.

Die Eintrittsenden i und die Austrittsenden 2 einer ein Glied bildenden Gruppe von Röhren sind in bekannter Weise j e in einen besonderen Röhrenkopf 3 eingewalzt. Gemäß der Erfindung sind je ein die Eintrittsenden und ein die Austrittsenden eines Röhrengliedes aufnehmender Röhrenkopf in eine gemeinsame Blechplatte 4 eingesetzt, die zur Befestigung der Röhrenglieder am Rahmen 5 dient und nur so stark ist, daß sie noch federnd nachgeben kann. Ihre Befestigung erfolgt durch Klemmschrauben 6, die unter Benutzung von Unterlegscheiben über die Ecken der Platte greifen, und die Abdichtung mittels einer Dichtung 7 von geeignetem Material.The entry ends i and the exit ends 2 of a link forming one Groups of tubes are rolled into a special tube head 3 in a known manner. According to the invention, the entry ends and the exit ends are each one Tubular head receiving the tubular member inserted into a common sheet metal plate 4, which is used to attach the tubular members to the frame 5 and is only so strong that it can still give way. They are attached using clamping screws 6, which grip over the corners of the plate using washers, and the sealing by means of a seal 7 of suitable material.

Die Eintrittsenden i eines Gliedes sind mit den Austrittsenden 2 des mit ihm in einer Reihe liegenden benachbarten Gliedes in bekannter Weise durch eine Überwurfhube 8 verbunden, die in ebenfalls bekannter Weise mittels zweier in Ringkragennuten der Röhrenköpfe 3 greifender Bügel io auf je zwei Röhrenköpfen festgedichtet ist.The entry ends i of a link are connected to the exit ends 2 of the with him lying in a row adjacent link in a known manner by a Union cap 8 connected in a known manner by means of two in annular collar grooves the tube heads 3 gripping bracket io is firmly sealed on two tube heads each.

Die Blechplatten q. sind zweckmäßig mit durch Klappen i i verschließbaren Schauöffnungen 12 (Fig. i) versehen.The sheet metal plates q. are expediently closable with flaps i i Inspection openings 12 (Fig. I) provided.
