Description

Befestigung von in einer Ebene liegenden Überhitzerrohrschlangen an von einem Kühlmittel durchströmten Tragrohren Die Erfindung betrifft die Befestigung von in einer lotrechten Ebene liegenden iJberhitzerrohrschlangen mit waagerechten Rohrschenkeln an in der gleichen Ebene liegenden, von einem Kühlmittel durchströmten, lotrechten Tragrohren. Sie besteht darin, daß die Umkehrbogen zweier benachbarter, in einer Ebene liegender Rohrschlangen durch Zwischenschweißen kurzer Stege. aus Flacheisen zu einer in der Verlängerung des Tragrohres durchlaufenden Tragkette verbunden sind.Attachment of superheater coils lying in one plane Support tubes through which a coolant flows. The invention relates to the fastening of superheater coils lying in a vertical plane with horizontal ones Pipe legs on lying in the same plane, through which a coolant flows, vertical support tubes. It consists in the fact that the reverse arcs of two neighboring, Coiled tubes lying in one plane by welding short bars between them. the end Flat iron to a carrying chain running through the extension of the support tube are connected.

Es ist bekannt, bei Rohrschlangen mit waagerechten Rohrschenkeln durch Zwischenschweißen von Stegen die einzelnen übereinanderliegenden Rohrschenkel gegenseitig zu befestigen. Da diese Stege jedoch hinter den Rohrbogen am Beginn der geraden Rohrstrecke liegen und der gegenseitige Abständ der Rohrmitten mit Rücksicht auf den kleinstmöglichen Krümmungshalbmesser der Rohrboden und die Entwässerbarkeit des IUberhitzers nicht beliebig klein gemacht werden kann, erhalten diese Stege eine Länge, bei welcher ihre Wärmeaufnahme die Wärmeabgabe an die Rohre bei weitem übersteigt. Sie müssen daher, sofern sie nicht verzundern sollen, aus einem hochlegierten, hitzebeständigen Sonderwerkstoff hergestellt sein.It is known to work with pipe coils with horizontal pipe legs Intermediate welding of bars between the individual pipe legs lying one above the other to fix. Since these webs are behind the pipe bend at the beginning of the straight Pipe section and the mutual spacing of the pipe centers with consideration the smallest possible radius of curvature of the tube sheet and the drainability of the superheater cannot be made arbitrarily small, these webs are preserved a length at which their heat absorption by far the heat dissipation to the pipes exceeds. They must therefore, if they are not to scale, made of a high-alloy, special heat-resistant material.

Bei einer- anderen bekannten Ausführungsform wird die Verwendung von Sonderwerkstoffen zwar dadurch vermieden, daß in der Ebene der Rohrschlange ein-Tragrohr an dem Umkehrbogen vorbeigeführt und jeder Umkehrbogen durch einen kurzen Steg an das Tragrohr angeschweißt wird. Die Länge der Stege von 15 bis 2o mm schließt Verzunderungen an den Verbindungsstellen aus und ermöglicht die Verwendung handelsüblichen Werkstoffes, doch muß jede Rohrschlange an beiden Seiten ein von oben bis unten durchlaufendes Tragrohr erhalten, was die Anbringung zahlreicher Tragrohre erforderlich macht.In another known embodiment, the use of Special materials are avoided by having a support tube in the plane of the coil guided past the reverse bend and each reverse bend by a short bridge the support tube is welded on. The length of the webs of 15 to 20 mm eliminates scaling at the connection points and enables the use of commercially available Material, but each coil must be one on both sides from top to bottom Get continuous support tube, which requires the attachment of numerous support tubes power.

Die vorliegende Erfindung sieht daher vor, die innenliegenden Umkehrbogen zweier benachbarter, in einer Ebene liegender Rohrschlangen durch Zwischenschweißen kurzer Stege so miteinander zu verbinden, daß eine lotrechte, durchlaufende Tragkette entsteht, die ein besonderes Tragrohr an dieser Stelle überflüssig macht. Die Verlängerung der Tragkette nach oben wird von dem oberen Anschlußrohr der Rohrschlange selbst gebildet, welches in der Verlängerung der Tragkette nach oben geführt und in bekannter Weise im Kesselgerüst aufgehängt ist. Auf diese Weise entfallen alle inneren Tragrohre; lediglich die äußerenUmkehrbogen der Rohrschlangen werden an durchlaufenden, besonderen Tragrohren befestigt.The present invention therefore provides for the internal reverse bends two adjacent pipe coils lying in one plane by intermediate welding short webs to connect so that a vertical, continuous support chain arises, which makes a special support tube superfluous at this point. The extension the carrying chain upwards is from the upper connecting pipe of the pipe coil itself formed, which led up in the extension of the support chain and in known Way is suspended in the boiler frame. In this way, all inner support tubes are omitted; only the outer bends of the pipe coils are attached to continuous, special Support tubes attached.

Die Abbildung zeigt ein Ausführungsbeispiel der Erfindung. Die Überhitzerrohrschlangen i sind in einer Ebene angeordnet und bilden mit ihren inneren Umkehrbogen unter Vermittlung der kurzen zwischengeschweißten Stege 3 eine lotrechte, durchlaufende Tragkette, die nach oben durch das Üherhitzerr ohr 4 verlängert ist. Dieses Überhitzerrohr4 sowie die außenliegenden Tragrohre 5, die in bekannter Weise durch die Stege 6 mit dem Umkehrbogen 7 der Überhitzerrohrschlangen i verbunden sind, sind in irgendeiner bekannten Ausführungsform am Kesselgerüst aufgehängt. Der von der Kesseltrommel kommende Sattdampf strömt durch die Tragrohre 5 in den Sammler ä, wird hier auf die Rohrschlangen i verteilt und gelangt nach Durchströmen dieser Rohrschlangen in den Sammler 9, aus welchem er durch das Rohr io entnommen wird.The figure shows an embodiment of the invention. The superheater coils i are arranged in one plane and form with their inner reverse arc below Mediation of the short inter-welded webs 3 a vertical, continuous Support chain, which is extended up through the Üherhitzerr ear 4. This superheater tube 4 and the outer support tubes 5, which in a known manner by the webs 6 with connected to the return bend 7 of the superheater coils i are in any one known embodiment hung on the boiler frame. The one from the boiler drum incoming saturated steam flows through the support tubes 5 into the collector ä, is here on the coils i distributed and arrives after flowing through these coils into the collector 9, from which it is removed through the pipe io.
