Abstract (en)
[origin: WO2015169562A1] The invention relates to a steam cycle (10) for a power station, and to a method for operating, in particular for starting, a steam cycle (10). The steam cycle (10) comprises a high-pressure turbine (12), a condenser (40) and a steam generator (30). The steam generator (30) is connected to the high-pressure turbine (12) via a first line (17). Live steam quick-closing valves (14) and live steam regulating valves (15) for supplying the high-pressure turbine (12) are arranged in the direction of the steam flow between the steam generator (30) and the high-pressure turbine (12). A starting line (23, 25) is arranged downstream of the high-pressure turbine (12) in the direction of the steam flow, said starting line connecting a waste steam region (13) downstream of the high-pressure turbine (12) with the condenser (40). At least one regulator (26, 29) is provided which regulates a closing of a starting valve (27) for sealing the starting line (25), and an opening of the live steam valve (15), depending on the rotational speed, a temperature and load state of the high-pressure turbine (12).
