Definitions

  • Turbine condenser for a steam turbine 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.
  • 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 then 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 sudden relaxation then has to As a consequence, depending on the pressure gradient, a hypersonic flow field develops locally. In addition, there is a risk that irradiated components, such as the adjacent turbine blades, the condenser tubes or the condenser walls are also excited to vibrate. Both result in the fact that the noise emission increases in the operation of the plant and thus if necessary prescribed maximum values are exceeded.
  • 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 serrated 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 bypass steam D from the bypass steam introduction device 1 is introduced into the turbine condenser 2.
  • Spargerrohr 3 or more generally a perforated basket - as a throttle device
  • 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 exemplary embodiment presented here downstream of the perforated basket 3 of the diverting steam introduction device 1, whose jagged edge is jagged - similar to a crown - in the turbine condenser 2.
  • 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 Umleitdampfstrahl 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 the introduction of steam can also be used as capacitor connection in axial turbine capacitors, laterally arranged “single-side exhaust” capacitors or on both sides laterally arranged “double-side exhaust” capacitors.
