Definitions

  • the present invention relates to the field of steam turbine technology. It relates to a method for producing a plurality of steam turbines for use in various applications, which are characterized by the respective thermodynamic parameters such as Cooling water temperature, ambient temperature, differentiate between given boiler data, process steam requirements, etc. wherein the steam turbines each have at least one high-pressure stage with a first Blading and have a control wheel stage for part-load operation.
  • the object is achieved by the entirety of the features from claim 1.
  • the essence of the invention is a fixed standard blading in the High pressure stage with a design that varies from application to application Combine control stage to match the steam turbine to the respective thermodynamic parameters of the application (e.g. condenser vacuum (Cooling water temperature), ambient temperatures, given boiler data of various Manufacturer, required process steam etc.). So limited the whole thermodynamic variability of the steam turbine in one only component (here: control wheel stage), both in terms of production technology, as well as procurement technology. Because especially the blading with the processing interface (Rotations) on the housing and shaft with regard to repetition effects has enormous potential for simplification and cost savings, a significant advantage is achieved by standardizing the blading.
  • a first preferred embodiment of the method according to the invention is characterized in that the steam turbines each have a central and have a low-pressure part with a second and third blading, and that as second and third blades also one for all steam turbines same standard blading is used.
  • standard blading will be an even greater simplification / saving achieved.
  • a second preferred embodiment of the method according to the invention is characterized by the fact that the control wheel stage sits on the rotor Control wheel and a plurality of concentrically arranged around the rotor axis Has nozzles, and that to design the control wheel stage, the control wheel and / or the arrangement and / or configuration of the nozzles can be varied.
  • a preferred development of this embodiment is characterized. that the number of nozzles is varied and / or that the geometry of the individual ones Nozzle is varied.
  • this Control wheel a third blading variation in which the wheel blade geometry, in particular the sheet thickness and / or the sheet height and / or the Curvature is varied.
  • the turbo group or steam turbine 10 comprises a high pressure part 11 with control wheel stage 13, a medium pressure part 12 and one (Optional) low-pressure part 22.
  • the steam turbine 10 drives a generator 23.
  • FIG. 2 is a longitudinal section of the example of a high-pressure part 11 with blading 16 and a control wheel stage arranged in front of the high-pressure part 11 13 shown, which are housed in a housing 21.
  • the rotating parts are arranged on a common rotor 18 which extends around a rotor axis 20 rotates.
  • the control wheel stage 13 contains one with its own blading (see in addition e.g. the US-A-4,812,107) equipped control wheel 19, which has a ring steam from an inflow duct 15 is acted upon by nozzles 14.
  • the number of nozzles 14 can be varied in particular in that Segments or sectors of the nozzle arrangement blind segments used become. Furthermore, the staggering angle of the nozzle profiles can be varied. Finally, a variation of the nozzle side wall contours is also conceivable.
