Erosion estimation for NPP turbine blades using generalized diagram

Generalized data on estimation criteria of erosion fracture used with various plants and companies are given as well as a generalized diagram for determining erosion characteristics of a stage on partial loads. An example of using the generalized diagram for determining relative change in unloading range of NPP powerful turbine depending on humidity at the end of the steam expansion process and reserve for admissible erosion is given
