Definitions

  • the invention relates to an air condenser with the features set forth in the preamble of patent claim 1 .
  • Air-cooled condensers serve for the direct condensation of exhaust steams, in particular of turbine steam. They can be regarded as a special application of air-cooled heat exchangers, which serve for the cooling of fluids in various processes of the chemical, petrochemical and power generating industry by means of ambient air.
  • the used heat exchangers essentially include heat exchanger tubes, which because of the poor thermal conductivity of air are provided with fins on the outside to facilitate heat transfer. Multiple of these tubes provided with fins, are combined to so-called tube bundles which, in planar construction, are exposed to a cooling air stream.
  • the cooling medium air is advanced through the heat exchanger bundles by means of ventilators in an aspirating or pushing arrangement.
  • the heat exchanger bundles are arranged roof-shaped above the cooling air ventilators.
  • the heat exchanger bundles which are arranged roof-shaped, and the ventilators which are arranged underneath are together supported by a support structure.
  • the turbine exhaust steam to be condensed is conducted through an exhaust steam duct and the adjoining upper steam distributor ducts into the fin tubes.
  • the constructional effort for the support construction is not insignificant.
  • the state of the art also includes air condensers in which tube bundles extend vertically and form a closed sheath of a polygon (EP 1 710 524 A1).
  • a polygon requires less space, because an elaborate support structure is not needed.
  • a disadvantage is however, that when doubling of the cooling capacity is desired, the for example hexagonally configured cells cannot be mounted in a space saving manner directly adjacent to one another, because in this case the two abutting sidewalls would cover one another and thus prevent aspiration of air through the heat exchangers that are arranged in these sidewalls. In a serial arrangement with for example three hexagonal cells, the opposing heat exchanger elements of the middle cell would be covered and of course also those of the neighboring cells.
  • the invention is based on the object to provide an air condenser which in modular construction can also be extended for higher cooling capacities, i.e. is easily scalable, which however, does not require an elaborate steel construction for supporting the tube bundles.
  • the air condenser according to the invention is characterized by upwards oriented tube bundles for condensing steam.
  • the tube bundles form sidewalls of a cell in the form of a circumferentially closed, upwards, i.e. vertically extending polygon, wherein the polygon itself lies in a horizontal plane.
  • This polygon which is configured with tube bundles as sidewalls, is provided with a fan which is arranged above the polygon in a manner so as to aspirate cooling air.
  • two of the circumferential sidewalls of the cell are formed by tube bundles, while the at least one further sidewall is impermeable to air.
  • the sidewalls formed by the tube bundles form an angle of 90° with one another.
  • This construction purposely provides for not using more than two sidewalls for the heat exchange, while the remaining sidewalls are closed, in order to seal the space enclosed by the cell so that cooling air is aspirated by the fan exclusively through the tube bundles. This allows combining multiple cells having this configuration, in a space-saving manner without blocking one another or delimiting a too narrow air intake space outside the cells.
  • the basic shape of such a cell is the triangle or a straight cylindrical hollow space with a triangular base area, respectively.
  • an air condenser is installed on a solid floor surface, so that an arrangement of the air condenser close to the ground obviates an elaborate support structure, as it is required for air condensers which are arranged roof-shaped.
  • the sidewalls formed by the tube bundles can well be longer than the at least one sidewall, which interconnects the spaced apart ends of the tube bundles. This results in a non-isosceles triangle. When multiple air-impermeable sidewalls are provided, these extend either between the confronting ends of the tube bundles or between the ends of the tube bundles which face away from each other.
  • a further basic shape is represented by deltoid cells.
  • a deltoid which is also referred to as kite quadrilateral, is a flat quadrilateral with two pairs of adjacent sides of equal lengths. Within the context of the invention, this means the convex shape of the deltoid. Applied to the invention this means that the tube bundles are one of two pairs of sidewalls of equal lengths, wherein the other pair of mutually adjacent sidewalls is formed by the air-impermeable sidewalls.
  • the strict deltoid shape can be interrupted by arranging a very narrow sidewall between the mutually adjacent ends of the tube bundles.
  • Narrow in this context means that the sidewall extends over a much smaller circumferential region of the cell than one of the neighboring tube bundles, thus creating a pentagon.
  • the basic shape of the pentagonal cell is configured mirror-symmetrical with regard to a vertical plane of symmetry intersecting the cell, however not rotationally symmetric. This means that due to the different lengths sidewalls, the basic shape of the cell cannot be projected onto itself when rotated by an angle different from 360°. This also has the consequence that the angle enclosed by the tube bundles is smaller than the angle enclosed by the air-impermeable sides. This means the inner angle of the cell enclosed by the directly adjacent tube bundles. Enclosed angle however, also means the angle which results when a narrow air-impermeable sidewall is further arranged between the mutually adjacent ends of the tube bundles.
  • the basic shape of the cell is trapeze-shaped.
  • the tube bundles which form an angle smaller than 90° with each other form legs of the trapeze, while the further air-impermeable sidewalls form the mutually parallel base sides of the trapeze.
  • the longer base side is the one which extends between the ends of the mutually distally positioned tube bundles.
  • the other base side, which extends parallel to the first base side, is significantly shorter corresponding to the angular position of the tube bundles.
  • the trapeze-shaped cell is a special form of the triangle-shaped cell.
  • a triangle-shaped or also trapeze-shaped cell the ends of the spaced apart positioned tube bundles, are connected to one another by sidewalls which are arranged U-shaped.
  • U-shaped in this context means that the sidewall does not extend in a straight line from the one tube bundle to the other tube bundle, but rather has an arched course, however, in particular is angled two-fold, resulting in a U-shaped course when viewing the cell from the top.
  • the cell has quasi a triangle- or trapeze-shaped part, whose sidewalls are formed by the tube bundles, and a rectangle-shaped part which is formed by the air-impermeable sidewalls. Of course, no closed intermediate wall is present between the triangle-shaped and the rectangle-shaped region.
  • the stacked arrangement it is regarded particularly advantageous, when multiple cells are combined to form an arrangement in which two rows are arranged horizontally adjacent to one another and extend parallel to one another, and in which the air-impermeable sidewalls are arranged so as to face one another and the sidewalls which are formed by the tube bundles form the outside of the rows.
  • the particular advantages of the invention that the tube bundles do not block one another come to bear.
  • the triangle cells, trapeze cells and deltoid cells can be arranged in one row without any impediment to airflow as well as in two rows, also referred to as in blocks, with the cells again not interfering with each other with regard to the air intake space.
  • Trapeze-shaped cells allow neighboring, confronting sidewalls to be in such close proximity to one another that one of the rear-side sidewalls can be omitted. In any case, however, one sidewall is retained, so that in a direct back-to-back arrangement no cooling air is aspirated by the fans of one of the trapeze-shaped cells through the heat exchangers of the other trapeze-shaped cell. Instead of being combined into a hexagonal cell, two trapeze-shaped cells thus remain trapeze-shaped in their layout.
  • the steam manifold which supplies the steam which is to be condensed, is arranged between the rows, so that junctions which branch off from both sides of the steam manifold can be guided to the top sides of the tube bundles.
  • the steam enters into the tube bundles from above.
  • the condensate which is generated in the tube bundles drains downwards and is discharged via condensate collecting mains.
  • the supporting structure of the tube bundles and the sidewalls is configured so that the steam manifold is supported as well.
  • less tonnage has to be moved, which allows realizing the installation of the entire air condenser in a more cost efficient-manner.
  • the new construction is especially economical compared to previous constructions.
  • significant savings can be achieved in air-cooled condensers with regard to material costs and installation costs.
  • the cost saving is primarily due to the fact that the heat exchanger bundles are mounted on a steel construction or concrete support, which are horizontally arranged on the ground.
  • the ventilation system which includes the fan, engine and the raceway which surrounds the fan, can be configured in a similar manner as in wet cooling towers which are configured in cell-type construction, wherein an inspection and maintenance of the ventilation system can occur through a bridge which hangs underneath the fan and is made in particular of glass fiber-reinforced plastics.
  • a tip means for example the region between two adjacent ends of the condenser. Because a door is preferably located at this position, the adjacent ends of the air condensers do not directly border one another, but are connected to one another via a narrow sidewall, which is not significantly wider than the door.
  • Steam exhaust duct means the duct between a turbine and a steam manifold.
  • the steam manifolds are arranged above the heat exchanger. Because of the small height in triangle cells, trapeze cells, kite cells or also in cells stacked upon one another, the steam exhaust duct does no longer have to be led to such a height as it is required in heat exchangers which are arranged roof-shaped. This results in a further reduction of material costs with regard to the steam exhaust duct.
  • installation costs are also significantly reduced, because less material has to be moved.
  • a decreased construction height also means that smaller cranes can be used, that scaffolds and safety devices are not needed or can be reduced, and that installation can take place with means used in residential construction.
  • a parallel mounting is possible, allowing to shorten construction time.

  • FIG. 16 a plan view on the supporting structure of deltoid shaped air condensers arranged in blocks.
  • FIG. 1 shows an air condenser 1 in a highly simplified and purely schematic representation which in cross section has a trapeze-shaped base area. Multiple of these air condensers 1 can be arranged adjacent to one another and as a result form a larger unit, which is then also referred to as air condenser. In this case, the individual unit shown in FIG. 1 is referred to as cell 2 .
  • the shown cell 2 has vertically extending sidewalls.
  • the sidewall 3 facing the viewer or the sidewall 4 positioned left in the image plane is formed by the not further shown tube bundles.
  • the rearward sidewall 5 like the face-side sidewall 6 , is closed. From the inside of cell 2 , air can be exhausted upwards by aspiration through a fan 7 , of which only the fan opening is shown. This causes cold ambient air to flow through the tube bundles or the sidewalls 3 , 4 , respectively, into the inside of cell 2 . Steam which is conducted into the tube bundles of the sidewalls 3 , 4 from above, condenses and can be conducted away via a not further shown condensate collecting main underneath the tube bundles. With the exception of the fan opening, the top side 8 of the cell 2 is closed, so that air can be aspirated exclusively through the tube bundles.
  • FIG. 2 differs from the one of FIG. 1 merely in that the front sidewall 6 is not present.
  • the basic shape of cell 2 is thus triangular.
  • the internal space of cell 2 is wedge-shaped.
  • FIG. 3 provides for a modification of the triangular- or trapeze-shaped cells 2 , as they are shown in FIGS. 1 and 2 . From this plan view it can be seen that it is a deltoid-shaped cell.
  • the deltoid-shaped cell 2 like the triangle- or trapeze-shaped cell 2 , again has two front sidewalls 3 , 4 in which the tube bundles are arranged. Located in the tip between the front sidewalls 3 , 4 is a narrow sidewall 6 , as in the trapeze-shaped configuration of FIG. 1 . Relevant is the difference on the rear side of cell 2 . Instead of a single sidewall, three closed sidewalls 5 , 9 , 10 are now provided.
  • the sidewalls 5 , 9 of the deltoid-shaped cell 2 are closed and form a greater enclosed angle with one another than the sidewalls 3 , 4 of the tube bundles.
  • the closed sidewalls 5 , 9 do not abut each other pointedly, but rather are connected to one another via a further sidewall 10 , which extends parallel to the front sidewall 6 between the tube bundles.
  • a further sidewall 10 which extends parallel to the front sidewall 6 between the tube bundles.
  • doors can be arranged for maintenance work.
  • a significant difference compared to the embodiments of FIGS. 1 and 2 is, that the fan opening in this type of construction is shifted further backwards towards the closed sidewalls 5 , 9 and lies only partially between the front sidewalls 3 , 4 or the tube bundles, respectively. This allows realizing greater fan diameters with regard to the total surface of the top side 8 .
  • smaller cells 2 can be used with regard to the base area at constant fan diameters.
  • the center M of the fan 7 lies on a straight line, which extends between the rear ends 11 , 12 of the sidewalls 3 , 4 or the tube bundles, respectively, which rear ends face away from each other.
  • FIGS. 4 to 8 show different variants of possible cross sectional shapes of the individual cells.
  • the front sidewalls 3 , 4 i.e. the tube bundles, form an angle W with one another, which is smaller than 90°.
  • FIGS. 4 and 5 essentially correspond to the ones of FIGS. 2 and 1
  • the variant of FIG. 6 and the one of FIG. 3 differ in that the sidewalls 6 , 10 in the tips are not present, thus resulting in an exact deltoid or kite quadrilateral.
  • the center M of the fan 7 does not lie exactly on the connecting line between the rear ends 11 , 12 of the sidewalls 3 , 4 , but is shifted somewhat in the direction of the sidewalls 3 , 4 .
  • the fan opening thus lies to a larger degree between the tube bundles. A small portion lies outside of the tube bundles.
  • FIG. 7 in contrast to the one of FIG. 3 , provides for only one front sidewall 6 , however no rear sidewall 10 .
  • the sidewalls 5 , 9 abut each other pointedly in an angle W 1 .
  • the angle W 1 is still greater than the angle W between the front sidewalls 3 , 4 in which the tube bundles are arranged.
  • FIG. 8 is a combination between a trapeze-shaped and a rectangle-shaped region.
  • the front region with the sidewalls 3 , 4 is formed by tube bundles, which in turn are interconnected via a narrow sidewall 6 .
  • V-form the deltoid-shaped cell shown in FIGS. 6 and 7 can be referred to as V-form.
  • FIGS. 9 to 12 show different possibilities of arranging multiple cells to a greater air condenser 1 .
  • the individual cells 2 are configured trapeze-shaped.
  • the bolder lines symbolize tube bundles 13 , 14 .
  • the thin lines represent closed sidewalls 5 , 6 .
  • FIG. 9 shows, that multiple of the shown cells 2 can be arranged in series, without the surfaces of the heat exchanger being covered.
  • FIG. 10 The same applies to the deltoid-shaped cells 2 , as they are shown in FIG. 10 .
  • the comparison between FIGS. 9 and 10 again makes clear how the fan 7 on the deltoid-shaped cells is shifted to the rearward region, which is closed by air-impermeable sidewalls 5 , 9 . In contrast to the embodiment of FIG. 9 , this allows the cells 2 to move slightly closer together, while the heat exchanger surface remains the same.
  • FIGS. 11 and 12 show possible block set-ups of the air condensers 1 .
  • FIG. 11 uses the cell type shown in FIG. 9 .
  • the cells 2 are arranged rearwards and at first sight form hexagons. However, it is a serial arrangement of purely trapeze-shaped cells 2 , wherein the trapeze-shaped cells 2 are closed by their rearward sidewalls 5 .
  • Air which is aspirated via fans 7 of the upper row 15 , can thus be aspirated only via heat exchangers of the upper row 15 , but not via the cells 2 of the lower row 16 .
  • FIG. 12 The same applies to the variant of FIG. 12 .
  • the deltoid-shaped cells of FIG. 10 are arranged in a block set-up.
  • the rows 15 , 16 are overall wider.
  • in return more installation space is available between the fans 7 which installation space can be used for guiding a steam manifold between the fans 7 .
  • FIG. 13 shows a possible arrangement of multiple rows 15 , 16 of trapeze-shaped cells 2 .
  • This fanned-out air condenser 1 can be fed by a central exhaust steam duct.
  • the individual cells 2 do not interfere with one another during air aspiration. Theoretically, any desired increase in cooling capacity is possible by extending the rows.
