Definitions

  • the invention relates, on one hand, to an air-cooled condenser system according to the features in the preamble of claim 1 .
  • the invention relates to a method for constructing an air-cooled condenser system according to the features in the preamble of claim 11 .
  • a conventional air-cooled condenser system has several condensers in the shape of a roof located on a platform, wherein the condensers are supported by pillars and are supplied with steam, wherein fans supported on the platform are located underneath the condensers.
  • the condensers in such condenser systems are typically arranged at a greater height, leaving adequate unobstructed space underneath the condensers through which the fans can suction the necessary cooling air from the environment of the condenser system and distribute the cooling air across the condensers for condensing the steam streaming through the condensers. Due to the height of the condensers, the wind loads acting on the condenser system are comparatively high, so that the entire substructure of the condensers system must be designed with adequate stability. In addition, it must be taken into account that the assembly of the condenser system requires a significant number of large pieces of equipment, such as cranes and scaffolding. In addition, the installers must work at great heights.
  • the pillars supporting the platform are anchored in the ground in an excavation formed in the soil underneath the platform.
  • This has the significant advantage that, after the pillars are introduced/driven into the ground, the platform can be installed with the heat exchanger elements and the steam distribution lines as well as the lines discharging the condensate directly at the height of the ground surface, i.e., close to the ground.
  • This significantly reduces the complexity and the assembly of the system, especially relating to cranes and scaffolding. The work is made much easier for the installers because they can now perform their work at a low height.
  • the size of the excavation or the slope angle of the preferably inclined edges is hereby dimensioned so that a sufficiently large unobstructed space exists underneath the platform which allows the cooling air suctioned from the environment by the fans to flow through.
  • the slope angle of the edges is approximately between 15° and 45°. A smaller slope angle below 15° would make the horizontal extent of the excavation quite large, requiring a large amount of material to be excavated.
  • the space required for the system and also the wind loads acting on the condenser system increase with decreasing slope angles. The wind loads decrease with a greater slope angle, so that the slope angle should remain below a minimum slope angle.
  • the slope angle of the excavation may not be identical on all sides of the excavation, but may be different, for example commensurate with the prevailing local wind direction.
  • a so-called stationary operation is desired in practical applications, i.e., in an operation where there is no wind.
  • it is ensured that all fans suction in cooling air and supply the cooling air to the heat exchanger elements almost uniformly.
  • the condensers receive cooling air unevenly, which reduces the condenser efficiency and hence also the efficiency of the power plant.
  • the condenser system with the heat exchanger elements is now arranged directly at the ground level, the wind speeds underneath the platform are comparatively low compared to conventionally supported condenser systems even at higher wind speeds. More uniform and hence more advantageous flow conditions are therefore attained even at higher wind speeds.
  • the wind loads acting on the condenser system in the horizontal direction can be significantly reduced, because the wind speeds at ground level are lower than at a height of, for example, 50 m.
  • the wind walls along the periphery of the heat exchanger elements can be of lighter weight and have a smaller height.
  • edges of the excavation should only start in regions near the platform, so that the air can flow to the side of the intake chamber without obstruction.
  • the distance between the surface of the floor of the excavation and the bottom edge of the platform can then be identical across the entire horizontal extent.
  • an intake chamber with sufficient height underneath the platform is attained when a horizontal floor surface of the intake chamber bounded by the sloped edges is greater than the horizontal base surface of the platform.
  • a mound with a sloped embankment may be provided on the floor of the excavation. This mound intentionally deflects cooling air from the entrance regions of the excavation on the side of the condenser system into the region underneath the heat exchanger elements, and simultaneously operates as a wind breaker.
  • the mound has a particularly high efficiency if its height is selected to be between 30% and 70% of the distance between the surface of the floor of the excavation and the bottom edge of the platform.
  • the height of the mount is about 50% of that distance.
  • the susceptibility of the condenser system to wind can be further reduced by arranging on the edge of the excavation a wall positioned on the ground.
  • the crest of this wall should be higher than the height of the platform.
  • the crest should be located in a horizontal plane intersecting with the top edges of the heat exchanger elements. This additionally creates a noise abatement wall by blocking sound propagating from the condenser system.
  • the wall may also be deposited with different heights commensurate with the prevailing wind direction, so that the crest must not necessarily have the same height at all places.
  • the wall may also be constructed only on one side or two sides of the condenser system and must not necessarily surround the entire condenser system, since the lengths of the lines from a turbine house, where the water vapor to be condensed is produced, to the condenser system should be kept as short as possible.
  • a wall placed on the side of the turbine house would increase the lengths of the lines. For this reason, a wall is preferably arranged only on three sides.
  • the wall may be constructed from the soil removed during excavation, so that additional building material need not be delivered.
  • the platform may even be installed at a relatively low height above ground level, if there exists already a significant distance from the ground level to the bottom edge of the platform. This distance is increased by removing soil below the platform for forming the intake chamber.
  • the excavated soil is used for the wall. In this way, the trough-shaped excavated area with a low depth can be formed, because the wall represents an additional wind barrier which reduces the susceptibility of the condenser system to wind.
  • pillars are first introduced into the ground, in particular driven into the ground or cast in the ground.
  • the platform is then installed on these pillars, with fans, heat exchanger elements and steam distribution lines attached to the platform, mentioning only the largest assemblies.
  • additional pipe systems and components may be arranged on such platform.
  • the soil underneath the platform is removed to a greater extent following the installation of the platform so as to form an excavated area which then operates as an intake chamber for inflowing air.
  • the intake chamber may be formed or enlarged by excavating soil.
  • the platform is arranged during the installation as close as possible to the ground. In other words, the pillars are introduced into the ground to a great depth.
  • the condenser system can quasi be installed on the ground.
  • the platform may also be installed at the height of, for example, 5 m or 10 m above the ground, wherein this night is subsequently at least doubled by removing soil so as to produce a sufficiently large intake chamber.
  • excavation is removal of the soil to an extent so as to significantly affect the flow conditions.
  • excavation should include soil removal of at least 1 m, preferably several meters, and over a larger area which represents at least 50% of the area underneath the platform.
  • a mound with a sloped embankment can be formed on the floor of the excavation.
  • forming is meant to indicate that the mound can be deposited or can remain while only the surrounding soil is excavated.
  • the second approach is much more advantageous because less soil needs to be moved.
  • the excavated soil can be used directly for depositing a wall on the side of the excavation.
  • additional material may of course be used.
  • the condenser system may then also advantageously be positioned at a somewhat greater height if it can be assumed that the crest of the wall is located approximately at the height of the platform, preferably at the height of the top edge of the condenser systems. In this case, the pillars need not be introduced too deeply into the ground.
  • the platform is then installed in a somewhat raised position, this is still not as difficult as an installation at a height of, for example, 50 m.
  • a wall may be deposited even if the condenser system is installed quasi at ground level. In this situation, the crest of the wall projects over the top edge of the condenser system, so that the condenser system is arranged in the trough-shape excavation and fully protected from the wind.
  • the edges of the excavation are constructed with a slope angle of 15° to 45°.
  • FIG. 1 in a schematic vertical cross-section, an air-cooled condenser system, and
  • FIG. 2 also in a schematic vertical cross-section, an air-cooled condenser system according to a further embodiment.
  • FIG. 1 illustrates an air-cooled condenser system designated with 1 .
  • This condenser system 1 includes a horizontal platform 2 which is supported by several vertical pillars.
  • Heat exchanger elements 4 supplied with steam, in form of condensers and dephlegmators, are arranged above the platform 2 in a roof structure.
  • Fans 5 supported on the platform are arranged below the heat exchanger elements 4 .
  • Steam distribution lines 6 extend on the ridge side of the heat exchanger elements 4 .
  • the required lines for feeding steam to the condenser system 1 and for discharging the condensate from the heat exchanger elements 4 are not illustrated so as not to obscure the clarity of the drawing.
  • Wind walls 7 are provided along the peripheral sides of the heat exchanger elements 4 and/or the platform 2 .
  • pillars 3 are first introduced with sufficient depth from the surface 8 of the ground 9 into the ground 9 .
  • the platform 2 with the heat exchanger elements 4 and with all steam and condensation lines, including the lateral wind walls 7 are installed on the pillars 3 , wherein the condenser system 1 is located directly proximate to the surface 8 of the ground 9 , a trough-shaped excavation 10 is excavated underneath the platform 2 .
  • the excavation 10 has lateral edges 11 which in the exemplary embodiment extend at an angle ⁇ of 25° with respect to the ground surface 8 , i.e., to the horizontal.
  • the edges 11 are arranged in regions next to the platform 2 .
  • a mound 12 with sloped embankments 13 is provided on the floor 14 of the excavation 10 underneath the platform 2 .
  • This mound 12 can be formed from the excavated material of the excavation 10 .
  • the height H of the mound 12 corresponds approximately to half the distance A between the surface 15 of the floor 14 of the trough 10 and the bottom edge 16 of the platform 2 .
  • the distance A also defines the height of the intake chamber 21 .
  • the intake chamber 21 is the region below the platform, via which air can flow to the fans 5 .
  • the arrows K indicate the cooling air suctioned by the fans 5 from the environment U of the condenser system 1
  • the arrows A indicate the outflowing air heated on the heat exchanger elements 4 during heat exchange.
  • a wall 17 is constructed on the ground 9 at the edge of the excavation 10 .
  • the crest 18 of the wall 17 extends approximately in a horizontal plane HE, which also intersects the top edges 19 of the steam distribution lines 6 of the condensers 4 .
  • the edges 11 transition smoothly into the sloped edges 20 of the wall 17 , i.e., the embankment 20 has the same angle as the edges 11 of the excavation 10 .
  • the platform 2 of the condenser system 1 is arranged at a greater height than the platform 2 in FIG. 1 .
  • the depth T of the excavation 10 may then be smaller, thus reducing the amount of material that needs to be excavated when building the excavation 10 .
  • FIG. 2 corresponds to that of FIG. 1 .
