Abstract

The invention relates to a method for operating a solar-heated continuous flow steam generator comprising an evaporator heating surface (4), whereby a target value (formula (II)) for the supply water mass flow (I) is fed to a device for adjusting the supply water mass flow (formula (I)). In order to further improve the quality of a predictive supply water or mass flow control and to maintain the enthalpy of the flow medium at the evaporator outlet particularly stable especially when load changes occur, a correction factor (Kf) is taken into consideration during production of the target value (II) for the supply water mass flow (I), said correction faction being characteristic of the temporal derivative of enthalpy, the temperature or the density of the flow medium at the inlet of one or more heating surfaces (2, 4). Said method is particularly suitable for operating a solar-thermal continuous flow steam generator (1) in a solar tower power station (129) with direct evaporation.
