CORROSION PROTECTION METHOD OF CONDENSERS OF STEAM TURBINES Russian patent published in 2020 - IPC C23F11/14 

FIELD: heat exchange.

SUBSTANCE: invention relates to heat engineering and can be used for corrosion protection of condensers of steam turbines of steam-powered power units, including steam and gas plants (SGP) on the side of cooling medium for the period of their repair or being in reserve. Method for corrosion protection of condensers of steam turbines includes adding a preserving agent to a closed circulation circuit, wherein preservative for not less than 10 hours is an aqueous solution of a preserving agent with concentration of 15 mg/dm³, containing in its composition heterocyclic organic compounds of class azoles, wherein the active substances in the preserving agent used are substituted analogues of 3-amino-1,2,4-triazole and 1H-benzotriazole.

EFFECT: technical result is creation of simple, relatively low-cost and effective technology of conservation of capacitors for the time of their withdrawal into standby (repair) with possibility of preliminary cleaning from deposits of different nature.
