Title:
METHOD AND APPARATUS FOR PREVENTING CORROSION OF STEAM GENERATOR
Document Type and Number:
Japanese Patent JPS61186486
Kind Code:
A
Abstract:
A method for the corrosion protection of steam generators having a housing containing feed water and enclosing a tube bundle with tubes conducting a heat carrier includes continuously determining the redox potential of the feed water during operation of the steam generator, continuously determining the corrosion potential of at least one tube of the tube bundle during operation of the steam generator, and negatively shifting the redox and corrosion potentials by changing the chemical conditioning of the feed water if the potentials indicate the danger of corrosion, and a device for carrying out the method.
