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.
  • To temporarily reduce the amount of steam generated by the steam turbine e.g. When starting up and shutting down or in case of malfunctions, not having to blow-off via safety valves to the outside, especially large steam turbines have a diverting device with which the excess steam can be discharged directly to the turbine condenser.
  • corresponding bypass steam inlets are provided with which the bypass steam is passed directly into the condenser of the turbine condenser.
  • 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 now enters the condenser dome with a high pressure level from the bypass steam device and with a significantly lower vapor pressure level, high velocity gradients result in the edge regions of the inflowing bypass steam.
  • the sudden relaxation has the consequence that, depending on the pressure gradient locally creates a hypersonic flow field.
  • irradiated components of the turbine condenser such as the turbine blades, the condenser tubes or the condenser walls are also excited to vibrations and thereby damaged. Both leads to the fact that in the Operation of the system increases the noise emission and thus possibly prescribed maximum values are exceeded.
  • the object of the invention is to provide a turbine condenser, which allows a reduced acoustic emission and also a controlled beam guidance of the introduced bypass steam.
  • the advantage of the invention thus lies firstly in the targeted alignment of the flow of the bypass steam away from critical components of the turbine condenser, such as, for example, the condenser bore arranged in the lower region or the turbine blading following at the upper end.
  • FIG. 1 shows a side view of a section of a stationary turbine condenser 1 with a condenser 2 and an overlying area which is referred to as a capacitor 3 due to its shape.
  • a diverting steam introduction device 4 is provided, with which diverting steam D is introduced into the turbine condenser 1.
  • a baffle plate is now provided as a baffle device 5 downstream of the bypass steam D emerging from the bypass steam inlet device 4. This one is like in FIG.
  • FIG. 2 shown in plan view formed so that the two horizontal edges of the pot-shaped baffle device 5 are inclined so that they deflect the diverting steam D in the horizontal direction toward the side walls 6 of the turbine condenser 1. This is in FIG. 2 indicated by the flow lines.
  • the pressure of the diversion steam D emerging from the bypass steam introduction device 4 is kept at a high level by the cup-like baffle device, so that a reduced acoustic emission and, moreover, a controlled beam guidance of the introduced bypass steam is ensured and thus the integrity of the turbine condenser is still ensured.
