FIELD: power industry.
SUBSTANCE: invention can be used for maintaining in heat power plants of optimum water and chemical mode (WCM) of the steam-and-water path, execution of wet cleaning and preservation in fuel firing power units and steam-gas power stations with providing in the set limits of the size pH of the working medium and creation on walls of thermal surfaces of protective magnetito-amine anticorrosive film. The complex reagent contains, wt %: monoethanol amine 19.0 - 21.0; morpholinium 7.0 - 8.0; cyclohexylamine 3.0 - 5.0; 1,3-oleyl propane diamine 2.0 - 3.0; ethoxylated fat alkylamines 0.5 - 1.5 and water - the rest up to 100%.
EFFECT: ensuring effective protection against internal corrosion of steam-and-water path at the pressure up to 16 MPa.
