Abstract

Die Offenbarung betrifft ein solarthermisches Kraftwerk mit mindestens einem Wärmeträgermedium-Speicher zum Speichern eines Wärmeträgermediums, in das Sonnenenergie eingekoppelt ist, und mindestens einem Wasserdampfkreislauf zum Erzeugung von Wasserdampf mittels eingekoppelter Sonnenenergie angegeben. Dabei weist der Wasserdampfkreislauf mindestens eine Speisewasservorwärm-Vorrichtung zum Vorwärmen von Speisewasser des Wasserdampfkreislaufs und mindestens eine Wasserdampfkreislauf-Bypass-Leitung zum Umgehen der Speisewasservorwärm-Vorrichtung auf. Die Wasserdampfkreislauf-Bypass-Leitung kann in Abhängigkeit von einem Betriebs-Modus des Wärmeträgermedium-Speichers aktiviert werden, so dass Speisewasser durch die Wasserdampfkreislauf-Bypass-Leitung strömen kann. Der Betriebsmodus des Wärmeträgermedium-Speichers ist insbesondere ein Entlademodus (Entladebetrieb) zur Entnahme von Wärmeträgermedium aus dem Wärmeträgermedium-Speicher. Daneben wird ein Verfahren zum Betreiben eines solarthermischen Kraftwerks mit folgendem Verfahrensschritt angegeben: Aktivieren der Wasserdampf-Bypass-Leitung in Abhängigkeit vom Betriebs-Modus des Wärmeträgermedium-Speichers, so dass Speisewasser durch die Wasserdampfkreislauf-Bypass-Leitung strömt. Mit Hilfe des Wasserdampfkreislauf-Bypasses wird im Entlademodus die Speiswassertemperatur abgesenkt. Dadurch erhöht sich die Temperaturdifferenz zwischen Wärmequelle und Wärmesenke und in Folge davon die Speicherkapazität des Wärmeträgermedium-Speichers.
