Abstract (en)
[origin: WO2013000720A2] The invention relates to an extraction method for a preheater of a steam power plant and to a water-steam circuit in a steam power plant. According to the invention, a higher-energetic steam is tapped on a turbine of the steam power plant and is admixed to a lower-energetic steam which is tapped on the turbine. The steam mixture of the lower-energetic steam and the admixed higher-energetic steam is fed to a preheater, in particular a high-pressure preheater, especially a last high-pressure preheating stage of the high-pressure preheater of the steam power plant, particularly for heating feed water flowing through the preheater. By an in particular regulated and/or controlled admixing of the higher-energetic steam to the lower-energetic steam (controlled extraction), a fast power change can be achieved in the steam power plant, particularly in part-load operation of the steam power plant, by changing the temperature of the lower-energetic steam.
