Abstract

A steam mixture from a thermo-compressor (11) is applied to the last preheating stage (HDV2) to raise the temperature of the feed water of a steam generator (1). KZÜ steam (Cold intermediate reheating steam) is fed from an outlet tapping (A1) of the high-pressure turbine (2) to an intake union (13) on the thermo-compressor (11). The operating steam here is steam from the generator (1) with which the KZÜ steam is compressed and mixed. Exergetically lower steam is extracted by a second thermocompressor from a tapping (A3) of a medium-pressure turbine (3) using operating steam from the steam generator (1). The steam mixture obtained is used to raise the temperature of the first preheating stage (HDV1) of the preheating system (6).
