Description

Die nachstehende Erfindung betrifft Verfahren und Vorrichtungen zur Strömungsführung von Luft im Ansaugbereich gebildet aus dem Raum unterhalb von auf Stützkonstruktionen stehenden luftgekühlten Kondensatoranlagen bestehend aus im wesentlichen vertikal durchströmten und im wesentlichen auf einer Ebene angeordneten Kondensationsmodulen mit Kühlelementen bevorzugt in Dachbauform zur Kühlung von Prozeß- und Turbinenabdampf. Die Kühlelemente können auch eben angeordnet sein.The following invention relates to methods and apparatus for Flow guidance of air in the intake area formed from the space below of air-cooled condenser systems on support structures consisting of substantially vertically flowed through and substantially on a level arranged condensation modules with cooling elements preferred in roof design for cooling process and turbine exhaust steam. The Cooling elements can also be arranged flat.

Luftgekühlte Kondensatoranlagen zur Kühlung von Turbinen- oder Prozeßabdämpfen bestehen in der Regel aus gleichartigen Modulen, die in mehreren Reihen parallel nebeneinander und hintereinander im wesentlichen in einer Ebene in Form eines Schachbretts angeordnet sind. Diese Anlagen stehen in der Regel erhöht auf einer im Raum unter ihr einen Ansaugbereich bildenden Stützkonstruktion. Jedes Modul ist mit einem Ventilator versehen, der die unter der Stützkonstruktion durchströmende Kühlluft ansaugt und im wesentlichen vertikal durch die Kühlelemente fördert. Für ungestörten Betrieb sollten alle Ventilatoren gleiche Luftmengen fördern um die zugrunde gelegte Kondensationsleistung einzuhalten. Dazu liegen die Module so auf einer Stützkonstruktion auf, daß nach Möglichkeit von allen Seiten eine gleichmäßige Zuströmung von Kühlluft möglich ist. Air-cooled condenser systems for cooling turbine or air conditioning Process abatement usually consist of similar modules that are in several rows parallel next to each other and one behind the other substantially in a plane in the form of a chess board are arranged. These plants are in usually increases on a space forming a suction area in the space below it Support structure. Each module is provided with a fan, which under the Support structure sucks through cooling air and substantially vertical promotes through the cooling elements. For undisturbed operation, all fans should same amounts of air promote the underlying condensation performance observed. For this, the modules are on a support structure that after Possibility of a uniform inflow of cooling air from all sides possible is.

Bei Seitenwind strömt Luft die Kondensatoranlage bevorzugt aus einer Richtung an und stört das Strömungsfeld im Ansaugbereich unterhalb der Module. Infolge ist ein Absinken der Kühlluftmenge in Teilen der Anlage zu beobachten, was zu einer Reduzierung der Kondensationsleistung führt. Die Erfahrung zeigt, daß insbesondere die außenliegenden, windnahen Module besonders ungünstig betroffen sind, da hier die größten Strömungsgeschwindigkeiten der Kühlluft auftreten. Als Folge dessen können die luftgekühlten Kondensatoren oftmals nicht mehr den erforderlichen Vakuumdruck am Austritt der Turbine gewährleisten, was zu Leistungsverlusten des Kraftwerkes führt. Unter ungünstigen Bedingungen steigt der Abdampfdruck derart an, daß zum Schutz der Turbine eine Notabschaltung eingeleitet werden muß. Weder einer Leistungsreduzierung noch einer Vollabschaltung des Kraftwerks ist für Betreiber akzeptabel.In crosswind, air flows through the condenser system preferably from one direction and disturbs the flow field in the intake below the modules. As a result is to observe a drop in the amount of cooling air in parts of the system, resulting in a Reduction of condensation performance leads. Experience shows that especially the external, wind-close modules particularly unfavorable are concerned, since here the largest flow velocities of the cooling air occur. As a result, the air-cooled capacitors often can not more to ensure the required vacuum pressure at the outlet of the turbine, which leads to power losses of the power plant. Under unfavorable conditions increases the Abdampfdruck such that for the protection of the turbine Emergency shutdown must be initiated. Neither a power reduction nor A full shutdown of the power plant is acceptable to operators.

Zur Vermeidung dieses Problems sind im Stand der Technik die Verwendung von Windleitwänden, Sperrwänden oder engmaschigen Zäunen am Umfang oder außerhalb der Kondensationsanlage bekannt. Sie haben den Sinn, den anströmenden Wind zu sperren und für ein ungestörtes Luftströmungsfeld unterhalb der Kondensationsmodule zu sorgen. Nachteilig an diesen Lösungen sind der hohe Kostenaufwand sowie die Erhöhung des Strömungswiderstandes für die Kühlluft, die nur durch erhöhten Energieverbrauch der Kühlventilatoren kompensiert werden kann. Ferner lassen in vielen Fällen örtliche Besonderheiten keine Umbauten um die Kondensationsanlage zu.To avoid this problem, in the prior art the use of Wind deflectors, barrier walls or close-meshed fences on the circumference or known outside the condensation plant. You have the sense that to block oncoming wind and for an undisturbed air flow field below the condensation modules. A disadvantage of these solutions are the high cost and the increase in flow resistance for the cooling air, only by increased energy consumption of the cooling fans can be compensated. Furthermore, in many cases leave local features no conversions to the condensation plant too.

Die Aufgabe der Erfindung besteht darin, unter Vermeidung der aufgeführten Nachteile den negativen Effekt von Seitenwind zu eliminieren oder zumindest weitgehend zu minimieren. Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß in dem einen Ansaugbereich bildenden Raum unterhalb der auf Stützkonstruktionen stehenden Kondensatoranlage Schikanen eingebaut werden. Als Schikanen können Wände zur Strömungsführung, sogenannte Windleitwände, eingesetzt werden. Fig. 1 zeigt eine luftgekühlte Kondensatoranlage bestehend aus vier Kondensatorreihen mit jeweils sechs Kondensatoreinheiten, in die eine bevorzugte Ausführung der Windleitwände eingezeichnet ist. Die Wände "A" und "B" sind dabei in Höhe der Ventilator-Einlaufdüsen über der gesamten Länge oder Breite der Modulreihen hängend angeordnet, wobei die den Luftstrom sperrende Tiefe dieser Windleitwände von der Anzahl der dahinter liegenden Module abhängt. Im Verhältnis zur lichten Höhe unterhalb der Stahlbaukonstruktion sperrt die Windleitwand im Fall "A" zwischen 1/(N - 1) und 1/N, mit "N" = Zahl der in Windrichtung hintereinander liegenden Module, der Höhe ab. Bei sechs oder mehr Modulen, wie im Fall der Windleitwand "B", erhöht sich die Versperrung auf 1/(N-2).The object of the invention is, while avoiding the disadvantages listed, to eliminate or at least substantially minimize the negative effect of crosswinds. This object is inventively achieved in that baffles are installed in the suction area forming a space below the stationary support structures on condenser system. As baffles walls for flow guidance, so-called wind deflectors, can be used. Fig. 1 shows an air-cooled condenser system consisting of four rows of capacitors, each with six capacitor units, in which a preferred embodiment of the wind deflector is located. The walls "A" and "B" are arranged hanging at the level of the fan inlet nozzles over the entire length or width of the rows of modules, wherein the air flow blocking depth of this Windleitwände depends on the number of underlying modules. In relation to the clear height below the steel construction, the wind deflector blocks in the case "A" between 1 / (N - 1) and 1 / N, with "N" = number of successive modules in the wind direction, the height. With six or more modules, as in the case of wind deflector "B", the obstruction increases to 1 / (N-2).

Bezüglich der äußeren Ventilatoren bewirken die Wände "A" und "B" ein Aufstauen der zuströmenden Luft unterhalb des Kühllufteinlasses der Ventilatoren und damit eine bessere Versorgung mit Luft. In vorteilhafter Weise wird hierdurch sogar die in dem Wind enthaltene Bewegungsenergie genutzt. Überraschenderweise zeigten Versuche, daß die optimierte Anordnung der Windleitwände keinen zusätzlichen Druckverlust für die Ventilatoren erzeugt, sondern im Gegenteil eine tendenziell bessere Versorgung der Module sicherstellt. Da die Windleitwände annähernd nur den Querschnittsanteil des Kühlluftstromes versperren der dem Anteil des auf die Module entfallenden Kühlluftstromes entspricht, werden die hinter den Sperrwänden liegenden Module nicht oder nur gering beeinflußt.With respect to the outer fans, the walls "A" and "B" cause damming the incoming air below the cooling air inlet of the fans and thus a better supply of air. Advantageously, even the in used the wind contained kinetic energy. Surprisingly, showed Attempts that the optimized arrangement of the wind deflectors no additional Pressure loss generated for the fans, but on the contrary a tendency ensures better supply of the modules. Since the wind deflectors almost only the cross-sectional portion of the cooling air flow obstruct the proportion of the on Modules corresponding cooling air flow, are behind the Barrier modules are not or only slightly influenced.

In einer weiteren bevorzugten Ausführungsform werden in geringer Höhe über dem Boden weitere Windleitwände "C" eingezogen die eine bessere Luftbeaufschlagung der unmittelbar hinter den oberen Trennwänden "A" und "B" liegenden Module gewährleistet. Die Höhe dieser in Bodennähe aufgestellten Windleitwände "C" beträgt vorzugsweise 1/N, maximal ¼ der lichten Höhe der Stützkonstruktion. Der bevorzugte Bodenabstand beträgt etwa 1 m, kann aber auch bei entsprechender Anlagegröße zur einfacheren Begehung der Anlage auf etwa 2 m erhöht werden. Diese Bodenwände "C" verleihen der unter den Modulen strömenden Kühlluft eine vorteilhafte Aufwärtskomponente. Die Verwendung solcher bodennahen Windleitwände hängt von den örtlichen Gegebenheiten, insbesondere der Hauptwindrichtung ab.In a further preferred embodiment, at a low height above the Ground more wind deflectors "C" fed the better Air admission directly behind the upper partitions "A" and "B" guaranteed lying modules. The height of these set up near the ground Wind deflector "C" is preferably 1 / N, a maximum of ¼ of the clear height of Support structure. The preferred ground clearance is about 1 m, but can even with the appropriate size of the plant for easier inspection of the system be increased about 2 m. These bottom walls give "C" the under the modules flowing cooling air an advantageous upward component. The usage such ground-level wind deflectors depends on local conditions, especially the main wind direction.

Die Windleitwände "A", "B" und "C" können in Stahlbau ausgeführt werden, aber auch andere Materialien wie Segeltuch, Kunststoffe oder Holzkonstruktionen sind zur Verwendung geeignet. Die Wände können statisch oder auch beweglich z. B. in Form von Rolltoren oder Jalousien angebracht werden. Die bewegliche Anbringung der Windleitwände ermöglicht eine Anpassung an die jeweilige Windsituation, besonders die Windrichtung und die Windgeschwindigkeit. Die Anpassung solcher beweglichen Wände kann automatisch oder manuell geschehen. Vorteilhafterweise können die erfindungsgemäßen Windleitwände in schalldämmenden Materialien ausgeführt werden, wodurch sich die Lärmemission der luftgekühlten Kondensatoranlage weiter verringern läßt.The wind deflectors "A", "B" and "C" can be executed in steel construction, but Other materials such as canvas, plastics or wood structures are suitable for use. The walls can be static or movable z. B. be installed in the form of roller shutters or blinds. The mobile one Attachment of the wind deflectors allows adaptation to the respective Wind situation, especially the wind direction and the wind speed. The Adaptation of such movable walls can be automatic or manual happen. Advantageously, the wind deflectors invention sound-insulating materials are executed, which reduces the noise emission the air-cooled condenser continue to reduce.

Vorteilhafterweise lassen sich die erfindungsgemäßen Windleitwände nicht nur in Neukonstruktionen von luftgekühlten Kondensatoranlagen integrieren sondern eine Nachrüstung von bereits bestehenden Kondensatoranlagen ist möglich. Advantageously, the wind deflectors invention can not only in New constructions of air-cooled condenser systems integrate but one Retrofitting of already existing condenser systems is possible.
