摘要： A water/steam cycle includes a steam generator, a steam turbine, a water cooled condenser and a feedwater pump. The condenser includes within a condenser shell at least one tube bundle with an internal air cooler, which is connected to an external ejector/vacuum pump by means of a suction line. In order to reduce the condenser evacuation time at the start-up of the water/steam cycle without using auxiliary steam, an additional evacuation line with a motorized isolating valve connects the external ejector/vacuum pump with the condenser shell. The action of the isolating valve is controlled by means of a control.
