This paper presents a life prediction model of radiant superheater tubes in steam generators of power plants. The objective is to generate relevant information for a decision and control system that will enhance the service life of steam generators in power plants specifically under transient conditions such as load following, start-up and scheduled shutdown. The key idea is to estimate the damage and damage rate in critical components such as radiant superheater tubes based on the available real-time sensor data and an analytical model. This information is also useful for making long-term strategies for operation planning and maintenance scheduling. The proposed life prediction module consists of the following two submodules: (i) a thermofluid dynamic and heat transfer model; and (ii) a thermoelastic and thermo-viscoplastic model of the tube material.
