← ScienceWhich inefficiency rises during rapid steam turbine start-up?
A)Increased condensation shock probability✓
B)Reduced blade fatigue tolerance
C)Elevated generator eddy current losses
D)Lower superheater tube creep rupture
💡 Explanation
Condensation increases because rapid heating hinders uniform thermal expansion, therefore more liquid accumulates than designed, leading to condensation shock formation, rather than gradual vaporization under consistent operational tempo.
