Abstract (en)

The method involves providing water circuit, where a steam turbine (4), pressure stage (8, 9, 10) and a condenser (6) is provided in a steam power plant (2). Water that is drained from the pressure stage of the steam power plant is collected, stored in a storage tank and recirculated into the water circuit of the steam power plant. Steam is applied to the condenser in the water circuit. An independent claim is also included for a steam power plant with water circulation.
