Which risk increases when turbine bypass control fails closed in a combined cycle power plant?

💡 Explanation

Superheater tube overheating occurs because the steam flow is prematurely diverted; steam velocity decreases while heat input remains constant, therefore metal temperatures rise rather than being effectively cooled. Other components are less impacted.
