TURBINE FATIGUE AND CREEP EVALUATOR

The methods and equipment for monitoring the turbine stresses are considered. Stresses in components are caused by steam pressure, centrifugal forces and temperature differences. The Turbine Stress Evaluator (TSE) determines thermal stresses during operation and compares them with limits established on the basis of anticipated operating schedules and conditions by means of appropriate low-cycle fatigue diagrams. The newly developed Turbine Fatigue and Creep Evaluator (TFE) is capable of determining low-cycle fatigue and creep accumulations on a continual basis. This monitoring device promises to become a highly effective preventive maintenance feature for turbines.
