摘要： The invention relates to a method for operating a combined gas and steam turbine system comprising a gas turbine (GT), a waste heat steam generator which is located downstream of the gas turbine (GT) in the direction of flow of the exhaust gas or fuel gas and includes at least one evaporator heating area (6) through which a moving fluid can flow, and a steam turbine (DT) which is located downstream of the waste heat steam generator in the direction of flow of the moving fluid. The moving fluid is fed to the waste heat steam generator in the form of feed water, a primary control loop being provided for predictively controlling the feed water flow rate. Taking into account the heat stored in the components in the evaporator heating area, a primary desired value for the feed water flow rate is determined on the basis of a desired overheating value that is characteristic of the temperature by which the moving fluid exceeds its boiling point as the moving fluid exits the evaporator heating area (6) and on the basis of a heat flow parameter that is characteristic of the heat flow transferred from the fuel gas to the moving fluid via the evaporator heating area (6), and the feed water flow rate is adjusted accordingly. The proposed method is characterized in that the desired overheating value is lowered from a normal value defined for the stationary operation of the gas and steam turbine system at a comparatively high efficiency to a smaller activation value in order to activate a temporarily available instantaneous power reserve.

摘要： The invention relates to a method for operating a continuous flow steam generator comprising an evaporator heating surface (4), whereby a target value (Ms) for a supply water mass flow (M) is fed to a device for adjusting the supply water mass flow (M). In order to 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 (K) is taken into consideration during production of the target value (Ms) for the supply water mass flow (M), said correction factor being characteristic of the temporal derivative of enthalpy or the density of the flow medium at the input of one or more heating surfaces (2, 4).
