Abstract

Die Erfindung betrifft eine Dampfkraftanlage (1) in welcher ein Arbeitsfluid (2) in einem Kreislauf umläuft, wobei eine regenerative Zwischenüberhitzung (30) vorgesehen ist, die vorzugsweise den gesamten Strom des Arbeitsfluids (2) vor dem Eintritt in eine Niederdruckturbine (11) zwischenüberhitzt und welche mittels Dampfentnahmen aus der stromaufwärts befindlichen Entspannungsstrecke (8) beheizt wird. Die die Zwischenüberhitzung (30) beheizenden Dampfströme werden bevorzugt zur Speisefluidvorwärmung (4) genutzt. Die Zwischenüberhitzung (30) ist als mehrstufige regenerative Zwischenüberhitzung (30) ausgebildet. Dies führt zu erhöhten Wirkungsgraden und geringerer Erosion an den Niederdruckschaufeln.
