摘要：

Methodology developed to evaluate the remaining life of a power plant reheater based on creep strain-rate estimate, and temperature and pressure measurements, is described. It uses well-known concepts from the literature on creep and is flexible to account for the cyclic operation of Brazilian power plants. The results computed for remaining life are compared with those obtained from the Larson-Miller approach, which does not take into account creep strain rate in the components subject to high temperature and internal pressure. The discrepancies verified between the two methodologies justify further research of on-line creep strain rate monitoring in order to assess the accuracy of the proposed methodology.
