Investigation on control in oxide scale formation and prevention of peeling off in ultra-supercritical unit

It is a common problem that oxide scale of boiler tube peels off in supercritic al unit. In recent years, many boiler tube burst accidents have been caused by oxide sc ale peeling off and blocking. Therefore, the analysis and research of oxide scale is of g reat significance. In order to control the occurrence of such accidents and reduce the ec onomic losses of thermal power plants, this paper mainly analyzes the factors influenci ng the oxide scale growth rate, peeling off condition and puts forward corresponding p revention and treatment measures.
