Steam turbine, method for cooling a steam turbine in ventilation mode and method for reducing condensation in a steam turbine in power mode

摘要

This invention concerns a steam turbine (1) which has guide vanes (5a). At least one guide vane (5a) has a hollow space (6). This hollow space (6) is connected with a fluid line (7) for introducing fluid (8) as well as port ducts (9a, 9b), which open at the outer surface (10) of the guide vane (5a). The invention also concerns a process for cooling the steam turbine (1) in ventilation operation.
