Study of Forming Exfoliation Mechanism of Oxide Skin in High-temperature Tube of Supercritical Boiler

摘要

In recent years, with the rapid development of supercritical units also brings some serious problems, for example, due to the oxide skin exfoliation of boiler tube caused many boiler tube explosion accidents. Aiming at this problem, the paper first introduced commonly used steel and its resistance to steam oxidation, and then the metal oxide skin formation and exfoliation mechanism is studied. These findings have a certain reference value for the power plant safe and economy operation.
