| Abstract: | This paper sets up a tube wall temperature online monitoring and life prediction system of high temperature heated surface of boiler by means of process simulation and modeling of the thermal system. With Integrated Modular Modeling Soft- ware （IMMS） as the foundation, the system online calculates temperature and the life of heated tube through three models： the high temperature heated surface thermodynamic calculation model, tube wall temperature calculation model and pipeline life calculation model, which uses existing DCS, SIS and MIS of power plant unit operation data from the information system. Ap- plication results show that the system can effectively reduce the number of tube fracture, guarantee the boiler working safe and economic |
