During shutdown of Steam Turbine,How do we cross the
critical speed?
Answer Posted / sbr
First off all we have to close prds line valve due to prds pre low and vaccume also low that meens condenser pre high in the case turbine was tripped with low vacume after that close the esv. Why turbine shaft free fall in down when ever having vaccume in condenser rpm slowly dicresed even that time shft having some load then we crose the critical speed some vibrations are coming so first shaft free only can crose the critical speed
