【Abstract】 The life assessment method for key components of domestically-made 300 MW units is introduced. Usingthe check and maintenance data of the power plants, and the various performance of metallic material, and helped bythe start-stop records and the operation mode statistics since the unit’s commission, the life assessment of the key com-ponents of the steam turbine is carried out. The life management system will play an important role in rational opera-tion of power plants, unit life extension, and efficiency improvement.更多还原
