摘要： A steam turbine with a shaft seal is provided. The shaft seal steam barrier is supplied with a slight excess pressure. In order to avoid complex additional devices necessary for liquefying the water vapor once again, a condensation chamber, which is sealed from the surrounding air as well as from the steam barrier chamber with brush seals, is provided between the steam barrier chamber and the surrounding air. The condensation chamber is constructed in such a manner that the heat, developing in the interior thereof, is discharged to the outside.

摘要： The invention relates to a method for heating a steam turbine comprising a high-pressure turbine section and a medium-pressure turbine section and/or a low-pressure turbine section. Said method is characterized by the essential aspect that the high-pressure turbine section is impinged upon by steam having relatively great conductivity while the medium-pressure turbine section or the low-pressure turbine section remains closed during said impingement following a cold start. As soon as the conductivity drops below a certain value, the medium-pressure turbine section or the low-pressure turbine section is also impinged upon by steam.

摘要： A method and a device are for operating a steam turbine in which includes several no-load or light-load phases. All phases are supplied with steam in order to ensure good preheating. The supply of a phase is selected in such a way that the phase produces the least possible output, preferably no output. The enthalpy differential between the entrance to and exit from the phase is thus preferably reduced to zero.

摘要： The invention relates to a method for starting a gas and steam turbine system which comprises a gas turbine system which comprises at least one gas turbine, in addition to at least one steam turbine system which comprises at least one steam turbine and at least one steam system. Heat produced by the working fluid and which is released in the gas turbine is guided to the steam system in order to produce steam which drives the steam turbine. According to the invention, during starting, the gas turbine is started prior to the steam turbine and the steam turbine is started in the presence of the first steam in the system and is impinged upon by said steam.

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.

摘要： A method for determining an approximate value for a parameter characteristic of the fatigue state of a component as a result of a time-varying stress to which it is subjected by means of a number of load cycles should, itself, during comparatively lengthy stress cycles, enable a prognosis concerning the current fatigue state of the component, this prognosis being, in particular, adapted to the needs and suited for the real-time determination of maintenance intervals. To this end, in addition to optionally already fully completed load cycles, a first partially completed load cycle is also taken into consideration during the determination of the parameter, whereby temporary stress values for phases that have not yet been run through of the partially completed load cycle are, together with a predetermined fixed value, taken into consideration.
