Method and device for determining service life consumption of individual components of a fossil fuel-fired power station, especially a combined gas and steam turbine power plant

The invention relates to a method for forecasting service life consumption of individual components of a fossil fuel-fired power station with regard to a load change to be carried out. The inventive method is characterized by determining, prior to the load change, actual variables characteristic of the condition of the power station, preajdusting a regulating notch of the power station producing the load change, calculating, based on the regulating notch and the characteristic variables, the load change time, and calculating a forecast service life consumption for at least a part of the individual components for the adjusted regulating notch. The invention also relates to a method for forecasting the expected load change time in a fossil fuel-fired power station. The inventive method is characterized by determining, prior to the load change, actual variables characteristic of the condition of the power station, so that the regulating notch and the expected load change time is calculated when the desired servi
