Abstract (en)
[origin: EP0561220A1] The invention relates to a process for operating a steam generating system, in particular in a fossil-fuel fired power station, e.g. in a gas and steam turbine system, in which steam is generated from water by indirect heat exchange with hot smoke gas (RG), condensed water (K) first being preheated and the preheated water (W) subsequently being evaporated under great pressure. The process is characterised in that, in the partial-load range of the system, the preheated water (W) under great pressure is cooled by heat exchange with at least a partial flow (t1) of the condensed water (K). Furthermore, the invention relates to a system with a steam generator (1), one heating surface of which is a condensation preheater (3). The system also comprises a heat exchanger (40) which is connected downstream of the condensation preheater (3) on the primary side and is connected upstream of the condensation preheater (3) on the secondary side. <IMAGE>
