Definitions

  • the invention relates to a condensation plant having the features set forth in claim 1 .
  • DE 34 21 200 A1 proposes a force-ventilated condensation plant with an aerodynamic wall for reducing the warm air circulation.
  • the flow velocity of the aerodynamic wall should exceed the exit velocity of the cooling air from the heat exchanger elements.
  • the use of easy-to-make wind shielding walls is omitted here, and a relatively large-volume nozzle arrangement is proposed instead, whereby the nozzles can be arranged above or to the side of the heat exchanger elements.
  • specially designed slotted nozzles which can be arranged on the perimeter of the condensation plant and may be supplied with cold or also warm air.
  • the condensation plant according to the invention includes at its perimeter a wind shielding wall which is comprised of plate elements, with the plate elements having a plurality of hollow chambers extending in vertical direction.
  • the hollow chambers of this wind shielding wall are used to form an air flow for creating an aerodynamic wall above the wind shielding wall.
  • the condensation plant according to the invention has the essential advantage that there is no need for installation of additional slotted nozzles or complex nozzle shafts because the already existing wind shielding wall is utilized for formation of an aerodynamic wall.
  • the introduced air flow is a cold air flow in particular which blends with the heated cooling air and reduces the negative impact of the residual warm air circulation solely by commingling.
  • Numerical tests have shown a significant reduction of the local warm air circulation rate by few percentage points, when the air flow has a suitable velocity. As a result, the condensation capacity is improved and thus the efficiency of the power plant is increased.
  • Transport of the accelerated air flow can be realized by a separate, e.g. mobile ventilator or also by branching off a partial flow of the cooling air conveyed by the fans which are associated to the peripheral heat exchanger elements.
  • the flow rate of the fans is however very high so that the volume flow is relatively high in the area of the aerodynamic wall in order to compensate the pressure drop.
  • the use of the existing wind shielding walls permits a temporary or permanent implementation of a flexible and at the same time effective solution for reducing the warm air circulation in a relatively simple manner and with little costs.
  • FIG. 1 shows a side view of a condensation plant with several roof-shaped heat exchanger elements arranged side-by-side and positioned between peripheral wind shielding walls;
  • FIG. 2 shows a plan view of the condensation plant
  • FIG. 3 shows a side view of a peripheral heat exchanger element adjacent to a wind shielding wall
  • FIG. 4 shows a further embodiment according to the illustration of FIG. 3 ;
  • FIG. 5 shows a cross section of a wind shielding wall, as used in FIGS. 3 and 4 .
  • FIGS. 1 and 2 show a condensation plant 1 with several heat exchanger elements 2 arranged side-by-side to which cooling air K is fed via fans 3 .
  • water steam fed by a steam manifold condenses within the heat exchanger elements 2 .
  • the heat exchanger elements 2 are surrounded in their entirety by a wind shielding wall 6 which is arranged at the perimeter 5 of the condensation plant 1 and prevents an instant and unimpeded warm air circulation.
  • the degree of the warm air circulation is greatly dependent on the locally prevailing wind direction. In particular the corner area of a condensation plant may experience a strong warm air circulation to adversely affect the condensation capacity and thus the efficiency of the power plant.
  • FIG. 1 shows by way of example the formation of such an aerodynamic wall 7 only in the area of the wind shielding wall 6 on the left-hand side of the drawing plane.
  • Corresponding perimeter sections 8 of an aerodynamic wall 7 are also shown, by way of example, in the plan view of FIG. 2 .
  • Such an aerodynamic wall is generally required only locally, especially when particular wind conditions prevail. The important fact is the formation of the aerodynamic wall 7 at any desired perimeter section 8 , without necessitating substantial structural modifications on the condensation plant 1 .
  • FIG. 5 shows an example in which a center plate element 10 with trapezoidal hollow chambers 9 is closed on both sides by planar plate elements 11 , 12 so as to form the required hollow chambers 9 .
  • FIGS. 3 and 4 show the manner of introduction of the air flow L into the hollow chambers 9 .
  • FIG. 3 shows the arrangement of a control flap 13 in the lower peripheral area of the wind shielding wall 6 for branching off a partial air flow L 1 from the cooling air flow K.
  • the control flaps 13 may be opened or closed, as required.
  • the air flow L may also be produced, at least proportionately, by auxiliary fans 14 .
  • the exemplary embodiment of FIG. 4 shows that the air flow L is comprised of the partial flows L 1 and L 2 which are generated by the auxiliary fan 14 and the fan 3 , respectively.
