  Wasserrohrkessel.

 durch die aussen liegende dichte Rohrwand in das Röhrenbündel eindringen, die entsprechenden Rohre der Rohrwand weggelassen. Dadurch wird aber die dichte Wand an dieser Stelle in der ganzen Höhe des Kessels unterbrochen, so dass der   Wärmeverlust nach aussen erheblich vergrössert   wird. 



   Zweck der Erfindung ist es, diesen Übelstand zu vermeiden. Dies wird   erfindungsgemäss   dadurch erreicht, dass an den Stellen, wo die Überhitzerrohre in das Röhrenbündel eindringen, die entsprechenden Rohre der aussen liegenden dichten Rohrwand auf eine solche Länge hinter die benachbarten Rohre abgebogen sind, dass Öffnungen entstehen, durch welche die Überhitzerrohre in das   Röhrenbündel   eingeschoben werden können. 



   Auf der Zeichnung ist der Gegenstand der Erfindung in zwei Ausführungsheispielen veranschaulicht,

 hitzers nach der Linie   J- ?   der Fig. 3. 



   Es soll zunächst die   Ausführungsform   nach Fig. 1 beschrieben werden. 



   Die   Obertrommel Jl   ist mit der Untertrommel B durch ein   Röhrenbündel   C verbunden. Die aussen liegenden Rohrreihen cl,   c2   sind zwecks Bildung gasdichter Rohrwände eng aneinandergelegt. Der Weg der Verbrennungsgase ist durch einen Pfeil angegeben. Innerhalb des Röhrenbündels befindet

 und unterhalb dieser Stellen die Rohrwand dicht geschlossen ist. 



   Bei der Anordnung nach Fig. 2 besteht der Überhitzer D aus einzelnen, an Sammelkästen d1 angeschlossenen U-Rohren, die so umgebogen sind, dass sie nach oben in das Siederohrbündel hineinragen. 



  In diesem Falle sind die   Überhitzerrohre   ziemlich nahe der Untertrommel B durch die dichte Rohrwand hindurchgeführt.   Die abgebogenen   Rohre   c2   sind daher unterhalb des Überhitzers nicht in die Ebene der

 penetrate the tube bundle through the tight tube wall on the outside; the corresponding tubes of the tube wall are omitted. However, this interrupts the tight wall at this point in the entire height of the boiler, so that the heat loss to the outside is considerably increased.



   The purpose of the invention is to avoid this drawback. According to the invention, this is achieved in that at the points where the superheater tubes penetrate the tube bundle, the corresponding tubes of the outer, tight tube wall are bent over to such a length behind the adjacent tubes that openings are created through which the superheater tubes are pushed into the tube bundle can be.



   In the drawing, the subject matter of the invention is illustrated in two exemplary embodiments,
 EMI1.2
 hitzers after the line J-? of Fig. 3.



   The embodiment according to FIG. 1 will first be described.



   The upper drum Jl is connected to the lower drum B by a tube bundle C. The outer rows of tubes cl, c2 are placed close together to form gas-tight tube walls. The path of the combustion gases is indicated by an arrow. Located inside the tube bundle
 EMI1.3
 and below these points the pipe wall is tightly closed.



   In the arrangement according to FIG. 2, the superheater D consists of individual U-tubes connected to collecting tanks d1, which are bent so that they protrude upwards into the boiler tube bundle.



  In this case, the superheater tubes are passed through the tight tube wall fairly close to the lower drum B. The bent tubes c2 are therefore not in the plane of the below the superheater
