FIELD: metallurgy.SUBSTANCE: corrosion protection method of a boiler plant involves stages at which: film is formed with composition M1FeO(M1: three-valence or four-valence metal) or M2FeO(M2: two-valence metal) on surface of inner wall of the boiler plant arrangement, which has been chose at least from feed water heater, degasser and steam generator; amount of added oxygen to the above device is controlled in compliance with temperature in the plant for maintaining the film in a stable state.EFFECT: increasing corrosion protection efficiency of the boiler plant by controlling the amount of dissolved oxygen.9 cl, 4 dwg |
