Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Den Gegenstand der Erfindung bildet ein schraubenförmig verdrehtes Überhitzerrohr.The subject of the invention is a helically twisted superheater tube.

Gegenüber bekannten ähnlichen Rohren besteht das Wesen der Erfindung darin, daß gewisse beliebig lange Abschnitte des Rohres oval gedrückt und dann verdreht sind, und zwar entweder nur nach einer Richtung oder abwechselnd nach verschiedener Richtung, wobei in letzterem Falle die Abstände unmittelbar aufeinander folgen können. Es sollen hierdurch Wirbelungen in dem Rohr entstehen, die einen besseren Wärmeaustausch bedingen.Compared to known similar pipes, the essence of the invention is that certain sections of the tube of any length are pressed oval and then twisted, and either only in one direction or alternately in different directions, whereby in the latter case the distances can follow one another directly. It should through this Turbulences arise in the pipe, which require a better heat exchange.

Auf der Zeichnung ist der Erfindungsgegen^ stand näher veranschaulicht.
Fig. ι zeigt in größerem Maßstabe die Verdrehung des Rohres.
The subject of the invention is illustrated in more detail in the drawing.
Fig. Ι shows the rotation of the tube on a larger scale.

Die Fig. 2 bis 4 zeigen verschiedene Ausführungsformen .FIGS. 2 to 4 show different embodiments .

Zweckmäßig wird das Rohr an den Verdrehungssteilen zunächst oval gedrückt, da hierdurch die Verdrehung erleichtert wird (Fig. 1). Wie Fig. 2 zeigt, sind die Verdrehungen nur an gewissen beliebig langen Stellen in Form einer rechtsgängigen Schraube angeordnet. Die Verdrehungen können auch abwechselnd nach rechts und nach links erfolgen (Fig. 3). Schließlich können sie derart erfolgen, daß die einzelnen Verdrehungen verschiedener Richtung ohne Abstand unmittelbar aufeinander folgen.Appropriately, the tube is initially pressed oval on the twisting parts, there this facilitates the rotation (Fig. 1). As Fig. 2 shows, the twists are arranged only at certain points of any length in the form of a right-hand screw. The rotations can also take place alternately to the right and to the left (Fig. 3). Finally, they can be done in such a way that the individual rotations are different Direction immediately following one another without a gap.
