← ScienceWhich outcome occurs when the gas turbine combustor temperature exceeds the material constant design limit?
A)Increased efficiency via enhanced heat rate
B)Accelerated blade creep within turbine stages✓
C)Reduction in NOx emissions from combustion
D)Stable operation improves thermal efficiency
💡 Explanation
Exceeding temperature limits leads to accelerated blade creep, because increased thermal energy activates the Arrhenius equation's exponential dependence. Therefore, material yield strength degrades faster, rather than improving efficiency which occurs with controlled temperature increases.
