The method involves using airflow with water mist for cooling the high pressure stage (8), medium pressure stage (10), and low pressure stage (12) of steam turbine (2), during a mist cooling phase. An air-cooling phase for cooling the pressure stages using the air flow, is performed before the mist cooling phase. A constant temporal temperature gradient is set for the cooling process during the air-cooling phase and mist cooling phase. |
