A power plant, particularly a coupled gas and steam power plant, including a plurality of first drainage lines that are fluidically connected on the upstream side to a water-steam circuit and are fluidically connected on the downstream side to an overpressure vessel, is provided. Additionally, at least one steam-conducting supply line, via which steam can be fed back to the water-steam circuit, is fluidically connected to the overpressure vessel. A method for operating such a power plant, wherein the at least one steam-conducting supply line can supply steam to the water-steam circuit in the region of a low-pressure stage, particularly in the region of the steam drum of the low-pressure stage is also provided.

Draining a power plant

The invention relates to a method for operating a steam power station and a power plant as well as a corresponding steam power station. According to the invention, essentially all of the water that is drained from at least one pressure stage of the steam power station is collected, stored, and recirculated into the water circuit of steam power station.

Method for operating a steam power plant, particularly a steam power plant in a power plant for generating at least electrical energy, and corresponding steam power plant

The invention relates to a method and a device for treating contaminated water in a steam power installation, and to a corresponding steam power installation. According to the invention, steam and water are separated between a first steam-collecting drum of a pressure level and a second steam-collecting drum of a lower pressure level.

Method and device for treating contaminated water

The invention relates to a method and device for removing water from a steam plant and to a steam plant with which, according to the degree of impurity of a number of partial volumes of water, a separate collection of the relevant partial water volumes is carried out.
