Abstract: An automation system that determines the theoretical maximum rate of cooling of a steam turbine and operates a steam generator in such a way that the thermal energy of the steam does not exceed nor drop below the predefined rate of cooling.

Abstract: Provided is a method for rapidly cooling a steam turbine, wherein ambient air is introduced into the steam turbine through a valve via an evacuation unit, resulting in cooling of the steam turbine, the rate of cooling being adjusted by an automation system including a controller.

Abstract: A method for shortening the start-up process of a steam turbine is provided which has a turbine housing and turbine components which are provided inside the turbine housing. The turbine components during operation come into contact with hot steam which flows through the turbine housing and include a turbine shaft which passes axially through the turbine housing. Sealing regions, which during operation of the steam turbine are acted upon by seal steam, are formed between the turbine shaft and the turbine housing. Thermal energy is fed to the steam turbine during a shutdown of said steam turbine, wherein seal steam is fed to the interior of the turbine housing during the shutdown of the steam turbine in order to heat and/or to keep warm the turbine components which are provided in the interior of the turbine housing.
