Abstract

Bei einem Verfahren zum Reinigen von Aggregaten einer Kraftwerksanlage im eingebauten Zustand wird ein kalorisch aufbereitete und unter Druck stehende Medium, vorzugsweise Dampf, über mehrere Stunden eingeblasen. Anschliessend dieser ersten Einblasung wird eine Ruhepause eingeschaltet, während welcher die zu reinigenden Aggregate abkühlen können. Nach dieser Abkühlung wird das Verfahren durch mindestens ein weiteres Einblasen wieder aufgenommen, das jeweils zu einem Thermoschock führt, der den erwünschten Reinigungseffekt auslöst.
