A method for prior determination of a life consumption of individual components in a fossil-fuelled power generating installation, with respect to a load cycling process to be carried out is provided. An apparatus is also provided for prior determination of a life consumption of individual components in a fossil-fuelled power generating installation, with respect to a load cycling process to be carried out. Actual variables which characterize the state of the power generating installation before a load cycling process are determined. A driving gear of the power generating installation which creates the load cycling process is set in advance. The load cycle time is calculated based upon the driving gear and the characterizing variables. A predicted life consumption for at least one of the individual components for the selected driving gear is also calculated.

Method and apparatus for determination of the life consumption of individual components in a fossil fuelled power generating installation, in particular in a gas and steam turbine installation

The invention relates to a waste heat steam generator of a gas fired and steam powered generator. Said generator comprises a waste heat boiler to which exhaust gas of a gas turbine can be supplied. Said steam generator also comprises at least one evaporator which is located in the waste heat boiler and is used to produce process steam for a steam turbine. According to the invention, flue gas from a heating device can be supplied to the waste heat boiler and at least part of said flue gas can be extracted at at least one point of the waste heat boiler and redirected back to the inlet of said waste heat boiler.
