A steam cycle for a power station, and to a method for operating, in particular for starting, a steam cycle. The steam cycle has a high-pressure turbine, a condenser and a steam generator. The steam generator is connected to the high-pressure turbine via a first line. Live steam quick-closing valves and live steam regulating valves for supplying the high-pressure turbine are arranged in the direction of the steam flow between the steam generator and the high-pressure turbine. A starting line is arranged downstream of the high-pressure turbine in the direction of the steam flow, the starting line connecting a waste steam region downstream of the high-pressure turbine with the condenser. At least one regulator regulates a closing of a starting valve for sealing the starting line, and an opening of the live steam valve, depending on the rotational speed, a temperature and load state of the high-pressure turbine.

Steam cycle, and method for operating a steam cycle

A module for a thermal power plant for condensing expelled vapors and cooling turbine effluent from the drained turbine includes a first unit designed to condense expelled vapors as well as a second unit designed to cool the turbine effluent, condensate from the first unit being transferable to the second unit.

Module for condensing expelled vapors and for cooling turbine effluent

A steam power plant is provided. The steam power plant includes a bypass pipeline which connects the fresh steam line flow to the exhaust steam line, wherein a bypass steam cooler is disposed in the bypass pipeline. In the event of an emergency stop, or a startup, or a shutdown, the bypass steam cooler cools the steam flowing into the bypass pipeline, whereby cheaper materials may be used for the bypass pipeline.
