摘要： The invention relates to a steam turbine system (1) comprising a steam turbine (2) which has a turbine housing and at least one turbine shaft (6, 7) accommodated in the turbine housing and sealed by means of seals (8) with respect to this steam turbine, a condenser (9) connected fluidically to the steam turbine (2), an evacuation unit (11) connected fluidically to the condenser (9), and a dry air source (17) which is connected fluidically to the steam turbine (2), wherein the steam turbine system (1) is designed in such a way that the evacuation unit (11) is optionally fluidically connectable to the dry air source (17). The invention further relates to a method for preserving components of a steam turbine system (1) to prevent idle-state corrosion, which comprises the steps: shutting down a steam turbine (2) of the steam turbine system (1) and sucking dry air into the steam turbine (2) using an evacuation unit (11) which additionally functions during intended operation of the steam turbine (2) to exhaust a resulting amount of gas into a condenser (9).
