Description
Der höchst erreichbare Wirkungsgrad eines Kraftprozesses würde dann erreicht werden, wenn es gelänge, den Carnotschen Kreisprozeß durchzuführen. Der Carnotsche Kreisprozeß würde sich z. B. ergeben, wenn man eine Turbine mit Sattdampf betriebe und sie zwischen Eintrittsdruck und Kondensatordruck in unendlich vielen Stufen anzapfte. Man würde dann im TS-Diagramm für dieses Verfahren eine Fläche erhalten, die mit dem Rechteck des Carnotschen Prozesses übereinstimmt. Geht man mit dem Druck dieses, Prozesses bis zum kritischen Druck, so geht | die Rechteckfläche in eine gerade Linie über, IThe highest achievable efficiency of a power process would then be achieved if it were possible to carry out Carnot's cycle. Carnot's cycle would z. B. result if you operate a turbine with saturated steam and they between inlet pressure and condenser pressure in an infinite number of stages. Man an area would then be obtained in the TS diagram for this method that corresponds to the The rectangle of the Carnot process. If you go with the pressure of this, Process up to critical pressure, this is how | the rectangular area in a straight line across, I.
d. h. der Prozeß wird imaginär.d. H. the process becomes imaginary.
Den Carnotschen Kreisprozeß in der. angegebenen "Weise durchzuführen, ist nicht möglich. Es gelingt aber, eine sehr weitgehende Annäherung an ihn zu erreichen, wenn man die Turbine mit Sattdampf betreibt und die Zahl der Anzapfstufen so hoch als möglich wählt, d. h. wenn man jede Stufe anzapft und das abgeführte Kondenswasser zur Speisewasservorwärmung verwendet. Ein derartiges Verfahren läßt sich durchführen, wenn man die Turbinenschaufeln in an sich bekannter Weise hohl ausbildet. Die Erfindung besteht darin, daß das aus den einzelnen Stufen der Turbine durch die Hohlschaufeln abgeführte Kondenswasser zur Speisewasservorwärmung dient. Das Verfahren arbeitet mit um so höherem Wirkungsgrad, je höher der Druck des zugeführten Sattdampfes ist, da hierdurch das Temperaturgefälle zwischen Eintrittstemperatur des Sattdampfes und Kondensatortemperatur vergrößert wird.Carnot's cycle in the. specified "way to carry out is not possible. But it is possible to get very close to him, if the turbine is operated with saturated steam and the number of tapping stages is as high as possible, d. H. when you tap into each stage and the drained condensation water used for feed water preheating. Such a procedure can be carried out if the turbine blades are designed to be hollow in a manner known per se. The invention consists in the fact that that from the individual stages of the turbine through the hollow blades The condensate drained away serves to preheat the feed water. The procedure works with the higher the efficiency, the higher the pressure of the supplied saturated steam, because this results in the temperature gradient between the inlet temperature of the saturated steam and the condenser temperature is enlarged.
