Abstract (en)

[origin: EP0595009A1] Preheated feedwater at high pressure is evaporated in a power plant having a fossil-fuel-fired steam generator (2), in which the heat contained in the flue gas (RG) from the furnace (12) is used to generate steam for a steam turbine (10) and the hot flue gas (RG) is denitrified. The steam therby generated is superheated before entry into the steam turbine (10) and after partial expansion in the steam turbine (10). In order independently of the load condition of the power plant to ensure a particularly favourable temperature response for the functioning of a denitrification device (15) provided inside the steam generator (2), it is provided in accordance with the invention that the feedwater is preheated solely outside the steam generator (2) and the flue gas (RG) is denitrified immediately following its exchange of heat with the partially expanded steam. The power plant working according to this method is distinguished by a particularly low technical complexity, the more so as there is no provision of an economiser previously provided inside the steam generator (2). <IMAGE>
