Which risk increases when turbine cooling in a combined cycle power plant malfunctions?

A)Reduced NOx formation efficiency
B)Premature hot section component failure
C)Decreased steam generator effectiveness
D)Elevated condenser back-pressure issues

💡 Explanation

Increased hot section component failure risk increases with inadequate turbine cooling due to thermal stress. Hot spots leading to creep occur because lacking convection exposes components above design limits. Therefore, premature component damage results rather than other thermodynamic effects in the cooling cycle.
