Description

Verfahren zur Kondensation bei atmosphärischem Druck bei Dampfkraftanlagen, insbesondere Lokomotiven, mit luftgekühlter Kondensationseinrichtung Die Abmessungen der für die Kondensation bei atmosphärischem Druck bestimmten Einrichtungen bei Dampfkraftanlagen hängen wesentlich von der Temperaturdifferenz zwischen dem niederzuschlagenden Dampf und dem Kühlmittel, z. B. der Kühlluft, ab. Je wärmer also das Kühlmittel ist, um so größer ist der Bauaufwand für den Kondensator oder der Leistungsaufwand für die Kühlluftförderung oder beides.Process for condensation at atmospheric pressure in steam power plants, especially locomotives, with air-cooled condensation device. The dimensions of the facilities intended for condensation at atmospheric pressure Steam power plants depend largely on the temperature difference between the to be precipitated Steam and the coolant, e.g. B. the cooling air. So the warmer the coolant is, the greater the construction cost for the capacitor or the power cost for conveying cooling air or both.

Besonders nachteilig macht sich dieser Umstand bei Lokomotiven mit Dampfniederschlag durch Luftkühlung bemerkbar, die in heißen Zonen weite Länderstrecken zu durchfahren haben. Die Kühllufttemperatur beträgt dabei erfahrungsgemäß nicht selten 5o bis 6o°, wodurch die Abmessungen der Wärmeaustauschflächen unwirtschaftlich groß werden müssen. Diese Nachteile zu beseitigen, ist der Zweck vorliegender Erfindung, deren Grundgedanke darin besteht, die Temperaturdifferenz zwischen Abdampf und Kühlmittel zu vergrößern bzw. den Dampfdruck im Kondensator durch geeignete bauliche Maßnahmen, z. B. durch ein Drosselventil am KondensatabfluB, bei hoher Außenlufttemperatur zu erhöhen, wodurch die Dampftemperatur innerhalb des Kondensators steigt und das Temperaturgefälle zwischen Kühlluft und Dampf günstiger wird. Daß durch diese Maßnahme eine gewisse ungünstige Rückwi-kung auf die Leistung der Maschine stattfindet, läßt sich nicht von der Hand weisen. Die Einsparung an Konstruktionsgewicht und Platzbedarf für den Kondensator ist jedoch bedeutend, so daß der Leistungsabfall der Maschine in Kauf genommen werden kann.This fact is particularly disadvantageous in the case of locomotives Steam precipitation noticeable due to air cooling, which stretches across the country in hot zones have to drive through. Experience has shown that the cooling air temperature is not rarely 5o to 6o °, which makes the dimensions of the heat exchange surfaces uneconomical have to grow big. To eliminate these disadvantages is the purpose of the present invention, whose basic idea is the temperature difference between exhaust steam and coolant to increase or the vapor pressure in the condenser through suitable structural measures, z. B. by a throttle valve on the condensate drain when the outside air temperature is high to increase, whereby the steam temperature rises inside the condenser and that Temperature gradient between cooling air and steam becomes more favorable. That this measure has a certain unfavorable effect on the performance of the machine takes place cannot be dismissed out of hand. The saving in construction weight however, the space requirement for the capacitor is significant, so that the performance degradation the machine can be accepted.
