Abstract

Die Erfindung betrifft einen Durchlaufdampferzeuger (2) mit einem aus miteinander über Flossen (13) gasdicht verschweißten Dampferzeugerrohren (10) gebildeten Gaszug, dessen Dampferzeugerrohre (10) für den Durchfluß eines Strömungsmediums parallel geschaltet sind, auf ihrer Innenseite eine Oberflächenstruktur zum Erzeugen einer hohen Strömungsturbulenz im sie durchströmenden Medium aufweisen und in einem Befeuerungsbereich (V) des Gaszuges annähernd in einer Spiralwicklung angeordnet sind. Um einen derartigen Durchlaufdampferzeuger (2) auch bei niedrigen Lastzuständen von beispielsweise etwa 20 % der Auslegungslast betreiben zu können, ohne daß überhöhte Wärmespannungen auftreten, sind die Dampferzeugerrohre (10) des Durchlaufdampferzeugers (2) erfindungsgemäß derart ausgelegt, daß bei ihrem Betrieb der geodätische Druckverlust des es durchströmenden Mediums mindestens das 0,5-fache von dessen Reibungsdruckverlust beträgt.
