Abstract
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 economizer of the forced-flow steam generator includes at least one high pressure pre-heater and/or a heat transfer system for preheating the working medium, the at least one high-pressure pre-heater and/or the heat transfer system arranged upstream as viewed in the working medium circuit direction, wherein if a predetermined partial load point 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 so 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, and a forced-flow steam generator for performing the method.
