ABSTRACT:
The invention relates to a method for operating a steam power installation, whereby steam produced in a boiler is condensed in a condenser after passing through at least one turbine, and the condensate obtained is preheated and redirected back to the boiler as boiler feed-water. In order to preheat the condensate, said condensate is split into a first partial current and a second partial current. Only the first partial current is preheated and the second partial current is then mixed with the preheated first partial current. The power of the turbine can thus be increased as required, up to the boiler reserve of the steam power installation.
