Based on safety production, the steam oxidation mechanism and property for inner wall of tube at thermal power plant boiler are described. Influence factor and opportunity of oxide scale exfoliation are put forward. Considering characteristics of different stages, such as design, operation, maintenance and inspection of ultra-supercritical unit, pre-vention measures of oxide scale are proposed. This research is of great practical significance and reference for safety operating at thermal power plant.
