Definitions

  • the invention relates to a turbine condenser according to the preamble of claim 1.
  • Turbine condensers serve to liquefy the exhaust steam of steam turbines.
  • Turbine condensers serve to liquefy the exhaust steam of steam turbines.
  • Such Umleitdampfein isten are usually equipped with a diverter valve for controlling the Umleitdampfmenge, a perforated basket as a throttle device to relax the bypass steam and a water injection for cooling the bypass steam.
  • the heat gradient to be throttled in such a diversion steam introduction is, as a rule, very large.
  • the vapor pressure before the bypass valve is usually up to 45 bar, while the back pressure in the turbine condenser can be given as about 0.1 bar. If this bypass steam stream with a high pressure level from the bypass steam device now enters the turbine condenser with a significantly lower vapor pressure level, high velocity gradients result in the edge regions of the inflowing bypass steam.
  • the object of the invention is to provide a turbine condenser, which allows a reduced acoustic emission.
  • the edge region of the nozzle is designed in the form of a chevron nozzle with serrated or toothed outlet edge. This results in a particularly effective mixing over the entire cross-section of the inflowing bypass steam, resulting in a consequent reduction in the uniform velocity gradients thus leading to a particularly effective reduction of the acoustic emission.
  • This shows schematically the region of the turbine condenser in which the diverting steam D from the diverting steam introduction device 1 is introduced into the turbine condenser 2.
  • the diverting steam D is introduced into the turbine condenser.
  • the diverting steam D then flows at high speed through holes (indicated by dashes in the figure) into the turbine condenser 2. This results in particularly high velocity gradients in the edge regions of the inflowing diverting steam D.
  • annular nozzle 4 is now provided in the inlet region, in the embodiment shown here downstream of the perforated basket 3 of the Umleitdampfeintechnischs issued 1, whose jagged in the turbine condenser 2 edge - like a crown - is formed.
  • Such embodiments of non-uniform edges are known, for example, from aircraft engine construction known as the chevron nozzle.
  • the edge formed unevenly by means of serrations Z the prevailing in particular in the edge regions of the introduced bypass steam broken high velocity gradient over the circumference of the inflowing bypass steam locally and thus changed locally.
  • an edge is formed, which may have elevations and / or indentations, which are arranged distributed uniformly or non-uniformly over the circumference of the edge.
  • the prongs or teeth can have any shape, such as a triangular or trapezoidal shape and also be bent as needed in the direction of the axis A of the nozzle. It is always important that the most uniform possible turbulent mixing of Umleitdampfstrahls with the surrounding steam in turbine condenser 2, which can cause a strong broadband noise and thus a high acoustic emission is effectively prevented.
  • the invention has been described in the preceding embodiment only in connection with a so-called “down-exhaust" turbine condenser with condenser tubes and overlying Kondenstordom as a transitional space for receiving the exhaust steam from the adjacent steam turbine, it can in principle be used in any type of turbine condenser.
  • the inventive design of the nozzle for introducing steam can also be used as a capacitor connection in axial turbine capacitors, laterally arranged “single-side exhaust” capacitors or on both sides laterally arranged “double-side exhaust” capacitors.
