Which consequence results when excessive regenerative feedback overwhelms a Rankine cycle?

A)Steam turbine blade stall occurs
B)Reduced condenser vacuum is created
C)Lower overall cycle thermal efficiency
D)Superheated water enters the boiler

💡 Explanation

Turbine blade stall occurs because excessive regenerative feedback causes backpressure, surpassing design limits therefore airflow disruption worsens, resulting in unstable turbine operation, rather than higher efficiency at design conditions.
