A method for operating a steam power plant having a water-steam circuit, according to which method the process wastewater produced is collected from the water-steam circuit, in a separated manner according to the degree of contamination thereof, in a number of partial wastewater quantities is provided. At least a first partial wastewater quantity having a first degree of contamination and at least a second partial wastewater quantity having a second degree of contamination are formed in the process. The second degree of contamination is higher than the first degree of contamination. The first partial wastewater quantity and the second partial wastewater quantity are mixed together in such a manner that a combined process wastewater is produced, which is fed to a wastewater treatment plant.

Method for recovering process wastewater from a steam power plant

An auxiliary steam generator system for a power plant, comprising a water-steam circuit, which has a condensate line and a feed-water line, wherein a condensate pump is connected in the condensate line and a feed-water pump is connected in the feed-water line, and wherein a pressure accumulating vessel is connected between the condensate pump and the feed-water pump, and wherein a feed-water take-off line is connected to the water-steam circuit at a branch-off point after the pressure accumulating vessel is provided. The feed-water take-off line is connected to the pressure accumulating vessel and a heating device is connected in the feed-water take-off line.

Auxiliary steam generator system for a power plant

In a steam power plant, a first cooling circuit includes a condenser for condensing steam and a first pump for pumping a first cooling fluid through the condenser in order to cool the condenser. A third cooling circuit is a closed cycle cooling circuit that utilizes a second cooling fluid for cooling down at least one component that is different from the condenser. A second cooling circuit includes a heat exchanger that thermally couples the first cooling fluid and the second cooling fluid and utilizes the first cooling fluid in the heat exchanger for cooling down the second fluid and further includes a second pump for pumping the first cooling fluid through the second cooling circuit independently from an operation of the first pump.
