What could be a consequence of not derating a gas turbine in high-temperature conditions?

In high-temperature conditions, failing to derate a gas turbine can lead to potential overheating and mechanical failure. This occurs because gas turbines are designed to operate within specific temperature limits, and excessive heat can cause materials to expand beyond their tolerances, resulting in stress or damage to critical components like turbine blades and seals. Derating, which involves operating the turbine at a lower power output under high temperatures, helps to mitigate these risks by reducing thermal stress. By ensuring the turbine does not exceed its thermal limits, the likelihood of operational failures and costly repairs is significantly diminished, promoting both reliability and safety in turbine operation.
