Abstract

Die Erfindung betrifft eine Rohrleitungsanordnung an einem Dampferzeuger mit Zwischenüberhitzerkreislauf, wobei die Rohrleitungsanordnung wenigstens Frischdampfleitungen und Zwischenüberhitzerleitungen umfasst, wobei die Frischdampfleitungen über schaltbare Ventile an den Zwischenüberhitzerkreislauf angeschlossen sind, so dass bedarfsweise Frischdampf in den Zwischenüberhitzerkreislauf abgelassen werden kann, wobei ein Rohrleitungsabschnitt von einer Ventile umfassenden Armatur in den Zwischenüberhitzerkreislauf als Abdampfstrecke ausgebildet ist, wobei die Abdampfstrecke n parallele Rohrleitungsabschnitte umfasst und vorzugsweise die Anzahl n der parallelen Rohrleitungsabschnitte der Anzahl der angeschlossenen Frischdampfleitungen (2) entspricht, und wenigstens ein Teil der parallelen Rohrleitungsabschnitte stromabwärts zusammengeführt sind.
