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).

Figure 00000001
The heat exchanger tube (3) for condensing steam (D) through cooling air (KL) with upper steam supply (2) and lower condensate discharge (17) has an elongated cross section in the flow direction of the cross-flowing cooling air (KL). The interior (9) of the heat exchanger tube (3) is through a partition wall (10) extending transversely to the flow direction of the cooling air (KL) into a condenser section (11) which becomes smaller in cross section in the flow direction of the steam (D) and into a conduit section (11) at the lower end (12) with the condenser section (11) connected in a steam-conducting manner, in the flow direction of the steam (D) the cross section of the dephlegmator section (13) is reduced. At the upper end of the dephlegmator section (13) there is a gas / vapor mixture suction (19).
