    摘要: A turbine plant (3), in particular a steam turbine plant, and a method (100) for cooling the turbine plant (3). The turbine plant (3) has a turbine (29) through which a process gas (15) flows in a flow direction (27) during operation. A cooling medium (7) is drawn or blown (120) through the turbine (29) either in or counter to the process gas flow direction (27) respectively, cooling the turbine (29). A fan (6) may be coupled to either a turbine inlet (4) or to a turbine outlet (5). The fan acts on the cooling medium (7, 110) which is drawn into the turbine (29) through the turbine inlet (4) or through the turbine outlet (5) to be blown (120) through the turbine (29) in or counter to the process gas flow direction (27).

    摘要: A method for controlling a cooling process of turbine components of a steam turbine shaft, wherein an air flow mixed with a water mist is used to cool the turbine components during a mist cooling phase (P4) is provided. The mist cooling phase (P4) is preceded by an air cooling phase (P3), during which an air flow is used to cool the turbine components. A constant temporal temperature gradient is specified for the cooling process, wherein the air flow density is adjusted by the valve position of a controllable regulating valve and a switch is made from the air cooling phase (P3) to the mist cooling phase (P4) if the maximum air flow density is reached and in particular if the regulating valve is fully open.
