Process and device for the protection of steam-raising units, particularly of nuclear reactors
Description
To protect the housing against corrosion by chemical conditioning of the feedwater, the redox potential of the feedwater and the corrosion potential of at least one pipe of the pipe bundle is continuously determined during operation of the steam raising unit. With potentials indicating the danger of corrosion, the quality of the secondary water can be improved by suitable measures. (orig./HP)

Zum Schutz gegen Korrosion durch chemische Konditionierung des Speisewassers wird im Betrieb des Dampferzeugers das Redox-Potential des Speisewassers und das Korrosionspotential mindestens eines Rohres des Rohrbuendels fortlaufend ermittelt. Bei auf Korrosionsgefahr hindeutenden Potentialen kann durch geeignete Massnahmen die Qualitaet des Sekundaerwassers verbessert werden. (orig./HP)Files
