Definitions

  • the invention relates to a power plant with a condensation plant according to the features in the preamble of patent claim 1.
  • Condensing systems are used for cooling turbine or process steams and have been used in energy engineering in very large dimensions for many years.
  • the efficiency of a power plant depends not inconsiderably on the condensation capacity of the condensation plant, the local climatic conditions and the related wind speeds and wind directions have a significant impact on the condensation performance.
  • Present-day types of condensation plants therefore have windbreak walls which surround the heat exchanger elements in their entirety in order to prevent recirculation of the heated cooling air.
  • condensation plant It is also important that all fans of the condensation plant are flown as evenly as possible. Higher natural wind speeds can lead to a local pressure drop below the fans. The fans concerned can not supply enough cooling air, which reduces the condensation capacity and may have to reduce the capacity of a turbine connected to the steam circuit.
  • the condensation plant may be in the lee of building structures, especially in the lee of the boiler house and the turbine house of a power plant.
  • a condensation plant as close as possible, that is built in the immediate vicinity of the turbine house, to keep the conduction paths short and to condense the water vapor as quickly as possible. Nevertheless, in order to ensure an optimal flow, condensation plants are already elevated relatively high, so that a substantially unimpeded flow from all sides, that is independent of the wind direction is possible.
  • the present invention seeks to show a power plant with a condensation system for the condensation of water vapor according to the features in the preamble of claim 1, wherein the warm air recirculation is reduced.
  • wind doors are provided for changing the flow area of the wind passages.
  • the width of the wind passages is often dictated by structural necessities. Often these distances will hardly change.
  • it can be controlled relatively accurately by wind gates, which air flow should be guided through the wind passages.
  • the wind doors are completely open in order to allow unimpeded passage of the incoming air.
  • it is also possible to close the wind gates at least partially when the wind speed is too high or when the wind direction has changed.
  • the wind gates can be coupled with means by which the flow area can be controlled as a function of the wind direction. For example, it could be a disadvantage if not the condensation plant, but the boiler and turbine houses are in the lee.
  • the condensation plant can "breathe", ie that it flows independently of the wind direction cooling air in a manner that prevents hot air recirculation.
  • FIG. 1 and 2 are two perspective views of a power plant model according to the prior art
  • 3 and 4 show two perspective views of a power plant model according to the solution according to the invention
  • Figure 5 is a model showing the flow conditions in a power plant according to the prior art.
  • Figure 6 is a model showing the flow conditions in a power plant according to the invention.
  • FIG. 1 shows a calculation model of a power plant 1 with a condensation plant 2 for the condensation of water vapor, which is supplied to the condensation plant 2 from a turbine house 3.
  • the turbine house 3 is preceded by a boiler house 4.
  • the turbine house 3 and the boiler house 4 are referred to in their entirety as building structures of the power plant.
  • the wind direction W is symbolized by the arrow.
  • the wind speed is for example 7 m / s.
  • the temperature profile of the exiting from the heat exchanger elements 5, heated cooling air can be seen, in particular, the circled area is of interest.
  • hot air recirculation is not limited to the circled corner region of the illustrated th condensation system occurs, but also in the area of the wind shadow behind the boiler and turbine houses 3, 4.
  • the reason for this can be seen in Figure 5.
  • the drawn arrows in Figure 5 illustrate the local wind direction.
  • the length of the arrows is a measure of the local wind speed.
  • the flowed in from the right in the image plane power plant 1 has a condensation plant 2, which lies in the lee of the building structure of a power plant, ie the boiler house 4 and in particular of the turbine house 3.
  • the condensation plant 2 is elevated high, the spatial proximity to the turbine house 3 means that the wind flowing in from the right in the image plane has to be sucked through a relatively narrow area under the heat exchanger elements 5 of the condensation plant 2.
  • the high number and density of the individual arrows in this area makes it clear that relatively high wind speeds prevail there. In turn, these high wind speeds lead to hot air also being discharged from the heat exchanger elements 5 at the edge of the condensation plant 2 and flowing back under the condensation plant 2.
  • FIG. 3 shows that the turbine house no longer represents a barrier to the cooling air flowing between the boiler houses 4, but instead delimits a wind passage 6, which is fluidically connected via a wind gate 7, which is only hinted at, to the suction space below the condensation installation 2.
  • the wind passage 6 is guided as a kind of tunnel through the turbine house 3.
  • FIG. 4 shows that the wind passages 6 open below the heat exchanger elements 5 of the condensation plant 2 arranged on a support structure 8 so that the air emerging from the wind passages 6 does not have to be completely sucked in over the roofs of the turbine houses 3 and boiler houses 4 can also be supplied directly via the wind passages 6 of the condensation plant 2.
