Description
Die Erfindung betrifft ein Solarwärmekraftwerk mit den Merkmalen des Oberbegriffs des Anspruchs 1.The invention relates to a solar thermal power plant having the features of the preamble of claim 1.
Solarwärmekraftwerke der eingangs genannten Art sind bekannt. Bei Ihnen wird das in der Brennachse der Parabolspiegelrinne mit dieser dem Sonnenstand entsprechend verschwenkt, das das Absorberrohr durchströmende Medium ist ein Thermoöl.Solar thermal power plants of the type mentioned are known. For you, this is pivoted in accordance with the position of the sun in the focal axis of the parabolic mirror channel, and the medium flowing through the absorber tube is a thermal oil.
Bei Verwendung eines Thermoöls aber sind die erreichbaren Temperaturen aber begrenzt, bei der Verwendung von überhitztem Wasserdampf sind die erreichbaren Temperaturen höher, es stellen sich aber dann Probleme, wenn das Absorberrohr mit der Parabolspiegelrinne verschwenkt wird, da dann Gelenke in den Fluidleitungen erforderlich sind.When using a thermal oil, however, the achievable temperatures are limited, with the use of superheated steam, the achievable temperatures are higher, but there are problems when the absorber tube is pivoted with the parabolic mirror groove, since then joints in the fluid lines are required.
Der Erfindung liegt die Aufgabe zugrunde, ein Solarwärmekraftwerk der eingangs genannten Art zu schaffen, das die Verwendung von überhitztem Wasserdampf als das Absorberrohr durchströmende Medium erlaubt.The invention has for its object to provide a solar thermal power plant of the type mentioned, which allows the use of superheated steam as the absorber tube flowing medium.
Erfindungsgemäß wird diese Aufgabe durch die Merkmale des Anspruchs 1 gelöst, die Merkmale des Anspruchs 1 geben eine bevorzugte Ausgestaltung an.According to the invention, this object is achieved by the features of claim 1, the features of claim 1 indicate a preferred embodiment.
Die Erfindung wird im Folgenden anhand einer schematischen Zeichnung erläutert, deren beide Figuren schematische Wiedergaben des Solarkraftwerks darstellen.The invention will be explained below with reference to a schematic drawing, the two figures represent schematic representations of the solar power plant.

Die hier vorgeschlagene Ausbildung eines Solarkraftwerks erlaubt die Verwendung von überhitztem Wasserdampf als das Absorberrohr durchströmende Medium. Der Druck in dem das Absorberrohr durchströmenden ersten Wasserkreislauf ist dabei relativ begrenzt, der Druck in dem die Turbine antreibenden zweiten Wasserkreislauf ist dagegen ausreichend hoch, um die Turbine anzutreiben. Die von dem Absorberrohr aufgenommen Wärmeenergie wird mit einem hohen Wirkungsgrad in elektrische Energie gewandelt.The proposed design of a solar power plant allows the use of superheated steam as the absorber tube flowing medium. The pressure in the absorber tube flowing through the first water cycle is relatively limited, the pressure in the turbine driving the second water cycle, however, is sufficiently high to drive the turbine. The heat energy absorbed by the absorber tube is converted into electrical energy with high efficiency.
