摘要： A steam turbine system including a steam turbine which has a turbine housing and at least one turbine shaft accommodated in the turbine housing and sealed by seals, a condenser connected fluidically to the steam turbine, an evacuation unit connected fluidically to the condenser, and a dry air source which is connected fluidically to the steam turbine, wherein the steam turbine system is designed in such a way that the evacuation unit is optionally fluidically connectable to the dry air source. A method for preserving components of a steam turbine system to prevent idle-state corrosion is also provided, which the steps: shutting down a steam turbine of the steam turbine system and sucking dry air into the steam turbine using an evacuation unit which additionally functions during intended operation of the steam turbine to exhaust a resulting amount of gas into a condenser.

摘要： A method for operating a condenser, wherein the condenser is designed for condensing water vapor to form water and during operation a condensate having water accumulates in the condenser, wherein on the condensate surface a plurality of floating bodies are arranged on the condensate, wherein the floating bodies float on the condensate, wherein a large number of floating bodies are used in such a way that the condensate surface is covered, wherein the floating bodies are of spherical and/or sphere-like design, and wherein floating bodies with different sizes are used.
