Definitions

  • the invention relates to a condensation plant having the features in the preamble of patent claim 1.
  • a forced-ventilation condensation system with an aerodynamic wall is proposed.
  • the flow velocity of the aerodynamic wall should be higher than the exit velocity of the cooling air from the heat exchanger elements.
  • the nozzles can be arranged above or to the side of the heat exchanger elements.
  • slot nozzles conceivable, which are arranged at the edge of the condensation plant and which can be charged with cold or hot air.
  • the present invention seeks to provide a condensation plant with an aerodynamic wall, which is at least partially switchable without major structural changes in case of need.
  • the condensation plant according to the invention has at its edge a windbreak wall constructed from plate elements, wherein the plate elements have a multiplicity of hollow chambers extending in the vertical direction.
  • the hollow chambers of this windbreak wall are used to form an air flow to create an aerodynamic wall above the windbreak wall.
  • the introduced air flow is in particular a cold air flow, which mixes with the heated cooling air and alone due to the mixing reduces the negative effects of the remaining warm air circulation.
  • Numerical checks showed a significant reduction of the local warm air recirculation rate by a few percentage points at suitable air flow rates. This leads to an improvement in the condensation performance and thus to an increase in power plant efficiency.
  • the promotion of the accelerated air flow can be accomplished with a separate, e.g. be done with a mobile fan or by branching a partial flow of the cooling air-promoting fans, which are associated with the peripheral heat exchanger elements.
  • the Figures 1 and 2 show a condensation plant 1 with several arranged in series heat exchanger elements 2, which is supplied via fans 3 cooling air K.
  • the water vapor supplied via a steam distribution line 4 condenses within the heat exchanger elements 2.
  • the heat exchanger elements 2 are surrounded overall by a windbreak wall 6 arranged on the edge 5 of the condensation plant 1, which prevents immediate and unhindered warm air recirculation.
  • the degree of warm air recirculation is highly dependent on the locally prevailing wind direction. In particular, in the corner region of a condensation plant, there may be strong warm air recirculation, which negatively affects the condensation performance and thus the power plant efficiency.
  • an aerodynamic wall 7 is formed above the windbreak wall 6, which constitutes an additional barrier between the hot air W flowing out of the heat exchanger elements 2 and the cooling air K drawn in from below.
  • FIG. 1 By way of example, it is shown that such an aerodynamic wall 7 is formed only in the area of the windscreen wall 6 left in the image plane. Corresponding edge portions 8 of an aerodynamic wall 7 are also exemplary in the plan view of FIG. 2 located. Such an aerodynamic wall is usually only local necessary, especially if very specific wind conditions prevail. It is crucial that the aerodynamic wall 7 can be formed at any desired edge portion 8, without significant structural changes to the condensation plant are required.
  • FIG. 5 shows an example in which a central plate element 10 with trapezoidal hollow chambers 9 is closed on both sides by flat plate elements 11, 12, so that form the required hollow chambers 9.
  • FIGS. 3 and 4 show how the air flow L is introduced into the hollow chambers 9.
  • FIG. 3 shows that in the lower edge region of the windbreak wall 6, an adjusting flap 13 is arranged, which branches off a partial air flow L1 from the cooling air flow K.
  • the butterfly valves 13 can be opened and closed as needed.
  • the air flow L can be generated at least proportionally by additional fans 14.
  • FIG. 4 shows that the air flow L from the partial flows L1 and L2 is composed, which are applied by the additional fan 14 and the fan 3.
