What is the life on saturated steam turbines?
A. It is expected to be 15 years since we are using hardened stainless steel for the turbine rotor. However, adequate care is to be taken to ensure that only dry steam enters the turbine and this can be simply accomplished by installing an efficient moisture separator (with thermodynamic trap) and a Y-strainer in the inlet line to the turbine. This is not included in standard scope of supply. SUPER COOLED VAPOUR: The steam existing the nozzle will be in a super cooled state and the passage through the turbine takes less than a milli-second. It takes about 1 to 2 secs, for condensation to occur and all the condensation will occur down stream of turbine, hence it is not harmful to the turbine. In addition, since it is a hardened stainless steel blisk, there is no erosion on saturated steam.
