  10. low-pressure turbine - an overview | ScienceDirect Topics

    When the inlet temperature of the reheat section becomes higher than 593°C, there is a risk of temper embrittlement in the inlet portion of the low-pressure turbine rotor after long-term operation. Actually, some turbine manufactures use slight rotor cooling at the inlet of the low-pressure turbine even for the 566°C-class reheat temperature.
