Abstract (en)
[origin: WO2011015185A2] The invention relates to a method for operating a forced-flow steam generator operating at variable pressure and at a steam temperature above 650°C and reducing the minimum forced-flow load of the forced-flow steam generator, wherein the forced-flow steam generator is incorporated in the water-/steam-conducting working medium circuit of a power plant and the economizer of the forced-flow steam generator comprises at least one high-pressure pre-heater and/or a heat transfer system for pre-heating the working medium, the at least one high-pressure pre-heater and/or the heat transfer system being arranged upstream as viewed in the working medium circuit direction, wherein if a predetermined partial load point ( LT ) is exceeded, the heat absorption of the working medium within at least one high-pressure pre-heater and/or the heat transfer system is reduced in such a way that the temperature of the water/steam working medium at the outlet of the economizer is below the boiling point relative to the corresponding economizer outlet by a predetermined temperature difference ( TD ), and a forced-flow steam generator for performing the method.
