← ScienceWhich outcome results when a power plant exceeds its condenser cooling capacity?
A)Decreasing turbine efficiency and power output✓
B)Lower combustion temperature improving efficiency
C)Increased steam quality at low pressure
D)Higher thermal conductivity in the boiler
💡 Explanation
Exceeding condenser capacity will reduce heat removal, elevating the turbine back pressure. Increased back pressure reduces the temperature differential, therefore decreasing steam turbine efficiency and power output driven by the Clausius-Clapeyron relation rather than improving conditions.
