Definitions

  • the present invention relates to a steam turbine system with a steam turbine, which has a turbine housing and a turbine shaft sealed by means of seals against this sealed turbine shaft, a fluidically connected to the steam turbine condenser, a fluidically connected to the condenser evacuation device and a dry air source, the fluidic with the steam turbine is connected.
  • Steam turbine which is often divided into several turbine stages. For example, a high pressure stage, one with ⁇ tel horriki and a low pressure stage may be provided.
  • Currency ⁇ rend the operation of the steam turbine system is fed to heated steam of the steam turbine and in this relaxed. In this case, thermal energy is converted ⁇ converts into mechanical energy which is used for driving a load such as a generator.
  • a capacitor is normally connected ver ⁇ which condenses the emerging from the steam turbine.
  • an evacuation ⁇ device is connected, which serves to suck the accumulating gas in the condenser.
  • a Evakuie ⁇ inference device for example, or may have a plurality of Evakuie ⁇ approximately pump.
  • the present invention provides a steam turbine system of the type mentioned, which is characterized in that the steam turbine system is designed such that the evacuation means is selectively fluidically connected to the dry air source.
  • the evacuation device which serves during normal operation of the steam turbine to suck the condenser gas produced in the condenser, with ⁇ run steam turbine the function of sucking dry air from the dry air source and to pass through the interior of the steam turbine system to condensate there incurred to absorb and to pay.
  • a sealing steam device is provided, which is set up such that the steam turbine can optionally be acted upon with sealing steam in the region of the seals.
  • sealing steam can be prevented that during the determ ⁇ mung normal operation of the steam turbine system can exit the steam turbine ⁇ vapor leaving through the seals.
  • the dry air source and the Sperrdampfein ⁇ direction are connected via a common line system to the steam turbine, wherein at least one valve is provided, which is set up such that the steam turbine is ⁇ optionally fluidically connectable with the sealing steam device or with the dry air source.
  • the evacuation device is preferably connected to an already existing line system of the sealing steam device ⁇ , which is associated with a simplified structure and an automatable startup.
  • constricting invention further provides a method of preserving the components of a steam turbine system, in particular a steam turbine system according to the invention, which comprises the steps ⁇ : shutting down the steam turbine and suction of dry air using an evacuation device intended during the Operation of the steam turbine serves to suck a gas accumulating in a condenser.
  • the steam turbine system 1 comprises a steam turbine 2 with a high-pressure stage 3 a and a medium-pressure stage 3 b and a low-pressure stage 4, which are connected to one another via an overflow line 5.
  • the high and medium pressure stage 3 a, 3 b and the low pressure stage 4 each have a turbine shaft ⁇ nen, 6, 7, wherein the turbine shafts 6, 7 stored in a ge ⁇ common or in separate, unspecified shown housings and in a known manner are sealed by means of seals 8.
  • the steam turbine system 1 further comprises a fluidically connected to the low-pressure stage 4 capacitor 9, to which a connection line 10 an evacuation device 11 is connected.
  • the condenser 9 is connected via a discharge line 12 to the high-pressure stage 3 a and the low-pressure stage 4.
  • Another component of the steam turbine system 1 is formed by a sealing steam device 13, which is fluidically connected to the interior of the high-pressure stage 3 a and the medium-pressure stage 3 b as well as the low-pressure stage 4.
  • a sealing steam line system comprising a provided with a shut-off valve 14 connecting line 15 and branching off this distribution lines 16 connected between the seals 8 to the high-pressure stage 3a and the medium-pressure stage 3b and to the low-pressure stage 4 are.
  • the steam turbine system 1 comprises a dry air ⁇ source 17 via a shut-off valve 18 provided with a drying air duct 19 to the connecting lead 15 of the locking steam line system is connected at a position between the shut-off valve 14 and the distribution lines 16.
  • the sealing steam ⁇ supply is interrupted by closing the shut-14th Furthermore, the shut-off valve 18 of the dry air line 19 is opened, so that now instead of sealing steam dry air from the dry air source 17 of the fluidically associated with this evacuation device 11 through the
