Fossil power plants are requested to be more efficient and reliable for longer operation against frequent start-ups and load changes, recently. To aid utilities in this endeavor, various technologies have been developed that provide a systematic approach to life assessment of critical facilities. Steam turbine facilities such as turbine rotor, inner casing, especially, may suffer from more severe creep and fatigue damage under high temperature and high pressure conditions. However, until now, to evaluate remaining life of turbine facilities, qualitative / semi-quantitative analysis is carried out without standard guideline or procedure in Korea. In this paper, the procedure for assessing the life consumption of turbine facilities is proposed based on creep and fatigue, generally accepted as dominant damage mechanisms of turbine facilities. According to the standard procedure, more reliable life assessment of turbine facilities and more effective maintenance can be possible.
