Definitions

  • the guide vanes have a hollow profile and form a guide surface forming the front wall (pressure side) and a rear wall (suction side), and that the tap is formed by an opening which is arranged in the region of the guide vane wall.
  • the tap is formed by a breakthrough, which is arranged in the region of the rear wall (suction side) of the guide vanes.
  • a steam turbine plant 10 is shown schematically, comprising a preheating section 12 with at least one preheater, here a total of seven preheaters 14, 16, 18, 20, 22, 24, 26 to a steam generator 11, such as heat exchangers, steam boilers or the like.
  • a steam generator 11 such as heat exchangers, steam boilers or the like.
  • Pre-heat supplied feed water 13 condensate from a condenser 28
  • the steam generator 11 for steam 15 is an expansion region 30, 32 downstream of the actual turbine assembly with z.
  • the turbines comprise a common turbine shaft 34 which, for example, drives an electric generator 36.
