During shutdown of Steam Turbine,How do we cross the
critical speed?
Answer Posted / kaizad
As soon as steam stop valves are closed there is no control on coast down speed of turbine unless vacuum break valve of condenser is opened. Normally it takes approximately 55mins to coast down from 3000rpm to 20-30rpm barring gear speed. We keep watch on all turbo visors parameters in such times
