Description

Anordnung zur Verbindung von Überhitzerschlangen mit überhitzersammelkästen durch Flansche. Die Erfindung bezieht sich auf L berhitzer, deren Rohre an den Sammelkästen durch Flansche angebracht sind. Allgemein ist die Flanschverbindung der Walzverbindung wegen ihrer leichteren Auswechselbarkeit vorzuziehhen. Es macht jedoch Schwierigkeiten, bei Flanschverbindung die notwendige Anzahl. Schlangen auf kleinen Raum unterzubringen, da zur Anordnung der Schrauben um jedes Überhitzerpaar eine bestimmte Breite des Flansches erforderlich ist.Arrangement for connecting superheater coils with superheater collecting boxes through flanges. The invention relates to L superheaters, the pipes of which are attached to the collecting tanks are attached by flanges. In general, the flange connection is the roller connection to be preferred because of their easier interchangeability. However, it makes difficulties the required number for flange connections. To accommodate snakes in a small space, because for the arrangement of the screws around each superheater pair a certain width of the Flange is required.

Gemäß der Erfindung wird eine gedrängte Anordnung der Rohre erreicht dadurch, daß die überhitzerrohre an beiden Enden mit versetzt angeordneten dreieckigen Flanschen an den Sammelkästen befestigt sind. In der Zeichnung zeigt Abb. i die einfache Anordnung.bekannter Art mit rundem Flanschen, Abb. z eine Anordnung bekannter Art bei Anwendung von ovalen Flanschen, Abb.3 und ¢ die Anordnung gemäß der Erfindung mit dreieckigen Flanschen im Grund- und Aufriß.According to the invention, a compact arrangement of the tubes is achieved in that the superheater tubes at both ends with offset triangular Flanges are attached to the collecting tanks. In the drawing shows Fig. I the simple arrangement of a known type with round flanges, Fig. Z an arrangement known type when using oval flanges, Fig.3 and ¢ the arrangement according to of the invention with triangular flanges in plan and elevation.

Die überhitzerrohre sind als Stegrohre ausgeführt und mit i bezeichnet.The superheater tubes are designed as web tubes and designated with i.

In Abb. i sind die Rohre in runde Flanschen z eingewalzt. Der Abstand zwischen Rohr und Schraubenloch ist mit a bezeichnet. Es ergibt sich dann ein Mindestabstand zwischen zwei Rohren von b.In Fig. I the tubes are rolled into round flanges z. The distance between the pipe and the screw hole is denoted by a. There is then a minimum distance between two tubes of b.

In Abb.3 sind ovale Flanschen 3 angewandt. Bei diesen ist der Abstand a sowohl zwischen Rohr und Schraubenlochkreis als auch zwischen Rohr und der schmalsten Stelle des Flansches eingehalten. Es wird hierdurch bereits der geringere Abstand der Rohre c erreicht.In Fig.3 oval flanges 3 are used. With these is the distance a between the pipe and the bolt hole circle as well as between the pipe and the narrowest one Position of the flange complied with. This already results in the smaller distance the tubes c reached.

In Abb. 3 sind die Rohre i gemäß der Erfindung in dreieckige Flanschen 4. eingewalzt. Der Abstand a tritt wieder zwischen Rohr-und Schraubenlöchern sowohl wie zwischen dem Rohr und der Außenkante des Flansches auf. Durch die Schräglage ist es möglich, deri Rohrabstand auf d zu vermindern. Um weiter die dreieckigen Flanschen möglichst nahe an die Rohre setzen zu können, ist es vorteilhaft, die Schrauben 5 (Abb. q.) in bekannter Weise mit Hammerkopf 6 zu versehen und die Flanschen q. derart in die Sammelkästen 7 zu befestigen, daß die Hammerköpfe längsliegen und so den geringsten Abstand benötigen.In Fig. 3 the pipes i according to the invention are in triangular flanges 4. rolled in. The distance a occurs again between both pipe and screw holes as between the pipe and the outer edge of the flange. Due to the incline it is possible to reduce the pipe spacing to d. To continue the triangular To be able to place flanges as close as possible to the pipes, it is advantageous to use the Screws 5 (Fig. Q.) To be provided in a known manner with hammer head 6 and the flanges q. in such a way to fasten in the collecting boxes 7 that the hammer heads lie lengthways and so need the smallest distance.

Die drei nebeneinandergestellten AbbildÜngen zeigen deutlich, daß die Abstände der Rohre voneinander nach der normalen Anordnung mit runden Flanschen am weitesten sind, bei der Anordnung mit ovalen Flanschen schon nähergerückt und bei der Anordnung gemäß der Erfindung am dichtesten sind. In allen Fällenist der Rohrdurchmesser der überhitzerrohre der gleiche, so wie die Flanschenstärke um das Rohr herum bzw. zwischen Rohr und Schraubenloch die gleiche ist.The three images placed side by side clearly show that the distances between the pipes according to the normal arrangement with round flanges are furthest, in the arrangement with oval flanges, and have already moved closer are closest in the arrangement according to the invention. In all cases the Tube diameter of the superheater tubes the same as the flange thickness around the Around the pipe or between the pipe and the screw hole is the same.

Von besonderem Wert ist die Erfindung für Überhitzer, die mit großem Rohrdurchmesser arbeiten, also für überhitzerrohre mit Einsetzstegen, sogenannten Stegrohr- oder Sternrohrüberhitzern.The invention is of particular value for superheaters with large Working pipe diameter, so for superheater pipes with insert webs, so-called Bar tube or star tube superheaters.
