Abstract

Das Wärmetauscherrohr (3) zum Kondensieren von Dampf (D) durch Kühlluft (KL) mit oberer Dampfzuführung (2) und unterer Kondensatabführung (17) weist einen in Strömungsrichtung der quer anströmenden Kühlluft (KL) langgestreckten Querschnitt auf. Der Innenraum (9) des Wärmetauscherrohrs (3) ist durch eine sich quer zur Strömungsrichtung der Kühlluft (KL) erstreckende Trennwand (10) in eine in Strömungsrichtung des Dampfs (D) im Querschnitt kleiner werdende Kondensatorstrecke (11) und in eine am unteren Ende (12) mit der Kondensatorstrecke (11) dampfleitend verbundene, in Strömungsrichtung des Dampfs (D) im Querschnitt kleiner werdende Dephlegmatorstrecke (13) gegliedert. Am oberen Ende der Dephlegmatorstrecke (13) befindet sich eine Gas/Dampfgemisch-Absaugung (19).
