Method for monitoring corrosion protection in power plant

摘要

According to one embodiment, there is provided a method for monitoring corrosion in a power plant, 5 including: forming a film with a composition of MlFeO3 (Ml: trivalent or tetravalent metal) or M2Fe2O4 (M2: divalent metal) on an inner wall surface of each of apparatuses of the power plant; and maintaining the film stably by controlling an amount of introduction of oxygen into each 10 of apparatuses commensurate with a temperature in each of the apparatuses. 2805737_1 (GHMatters) P87784 .AU 2/09/11 -14 18 19b 15 1.0x105 Region where Fe203 is stable o 1.0 x10 1.0x10-g F 0 250C 1850C 2250C Temperature
