Abstract

Bei einem Verfahren zum Betreiben eines solarbeheizten Abhitzedampferzeugers (1) mit einer Anzahl an Heizflächen (2, 4), bei dem einer Vorrichtung zum Einstellen des Speisewassermassenstroms (Formel (I)) ein Sollwert (Formel (II)) für den Speisewassermassenstrom (Formel (I)) zugeführt wird, soll die Qualität einer prädiktiven Speisewasser- oder Massenstromregelung noch weiter verbessert und insbesondere bei auftretenden Laständerungen die Enthalpie des Strömungsmediums am Verdampferaustritt besonders stabil gehalten werden. Dazu wird erfindungsgemäß bei der Erstellung des Sollwerts (Formel (II)) für den Speisewassermassenstrom (Formel (I)) ein charakteristischer Korrekturwert KT berücksichtigt, durch den thermische Speichereffekte von ein- oder ausgespeicherter thermischer Energie in eine oder mehrere der Heizflächen (2, 4) korrigiert werden. Das Verfahren ist in besonderer Weise für den Betrieb eines solarthermischen Abhitzedampferzeugers (1) in einem Solarturm-Kraftwerk (129) mit indirekter Verdampfung angepasst.
