Assessment of Remaining Useful Life of Power Plant Steam Generators – a Standardized Industrial Application

Abstract

The Web based condition monitoring and diagnostic system “Boiler Fatigue Monitoring” enables on-line assessment of cumulative boiler creep and low cycle fatigue according to the European standard EN 12952-3/4 issued in 2001.The application is employed as autonomous module as well as fully integrated into the Siemens process control system SPPA-T3000 and is becoming more and more a standard part of the power plant instrumentation and control (I&C).The Fatigue Monitoring System (FMS) is a standard industrial application for both, new built power plants and retrofits of existing units of any kind. The system is not limited to Siemens I&C systems, it is possible to integrate FMS also into power plants with I&C systems of other suppliers. FMS is also capable for calculating the remaining lifetime for boilers designed according to the American standard ASME VIII-2.
