METHOD OF ARRANGING WATER-CHEMICAL MODE OF BOILER AND STEAM TURBINE POWER EQUIPMENT Russian patent published in 2010 - IPC F22B37/48

Abstract RU 2379584 C1

FIELD: power engineering.

SUBSTANCE: according to the invention, depth of demineralisation of condensate and make-up water, when oxygen-free water-chemical mode (WCM) is performed after preliminary steam-water-oxygen cleaning and passivation of steam-water path is completed, is controlled by comparing redox potentials Eh of condensate and make-up water with electrode potential φ_e of passivated metal sample of the above path from condition φ_e>Eh.

EFFECT: creating the conditions in order to make it possible to change oxygen water-chemical mode for oxygen-free one which provides reliable protection of steam-water path of power equipment against corrosion.
