Description

Die nachstehende Erfindung betrifft ein Verfahren und eine zu einer Kondensatoranlage gehörende Vorrichtung 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 present invention relates to a method and a belonging to a condenser device for flow guidance of air in the intake formed from the space below standing on supporting structures air-cooled condenser systems consisting of substantially vertically flowed and arranged substantially on one level condensation modules with cooling elements preferably in roof design Cooling of process and turbine exhaust. 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 process vapors usually consist of similar modules which are arranged in several rows parallel next to each other and behind each other substantially in a plane in the form of a chess board. These systems are usually elevated on a support structure forming a suction area in the space below it. Each module is provided with a fan which draws in the cooling air flowing under the support structure and conveys it substantially vertically through the cooling elements. For undisturbed operation, all fans should deliver equal volumes of air to maintain the underlying condensation performance. For this purpose, the modules are on a support structure that, if possible, a uniform inflow of cooling air is possible from all sides.

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 from the condenser system preferably from one direction and disturbs the flow field in the intake below the modules as a result of a decrease in the amount of cooling air is to be observed in parts of the system, resulting in a reduction in condensation performance. Experience shows that especially the external, wind near modules are particularly affected unfavorable, since the largest flow velocities of the cooling air occur here. As a result, the air-cooled condensers often can no longer provide the required vacuum pressure at the exit of the turbine, resulting in power losses of the power plant. Under unfavorable conditions, the exhaust steam pressure increases so that an emergency shutdown must be initiated to protect the turbine. 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, the use of wind deflectors, barrier walls or close-meshed fences at the periphery or outside of the condensation plant are known in the prior art. They have the purpose to block the oncoming wind and to provide an undisturbed air flow field below the condensation modules. A disadvantage of these solutions is the high cost and the increase in the flow resistance for the cooling air, which can only be compensated by increased energy consumption of the cooling fans. Furthermore, in many cases, local features do not allow conversions around the condensation plant.

Anlagen ähnlicher Art sind bspw. in den Patentschriften DE 28 45 424 A , FR 2 360 059 A und US 6,320,271 B1 beschrieben.Methods and / or devices or systems of a similar kind are, for example, in the patents DE 28 45 424 A . FR 2 360 059 A and US 6,320,271 B1 described.

Die Aufgabe der Erfindung besteht darin, unter Vermeidung der oben aufgeführten Nachteile den negativen Effekt von Seitenwind zu eliminieren oder zumindest weitgehend zu minimieren um damit bei einem bestehenden Luftstrom der einer seitlichen Windeinwirkung ausgesetzt ist, die durch den bestehenden Luftstrom erzeugt Kühlung nicht so weit absinken zu lassen, dass die Kühlleistung unter einen kritischen Wert fällt.The object of the invention is, while avoiding the disadvantages listed above, to eliminate or at least substantially minimize the negative effect of crosswind, so that in the case of an existing air flow which is exposed to a lateral wind action, the cooling generated by the existing air flow does not decrease so much let the cooling capacity fall below a critical value.

Diese Aufgabe wird erfindungsgemäß durch ein Verfahren gemäß dem Anspruch 1 sowie durch eine Anlage gemäß dem nebengeordneten Anspruch gelöst. Vorteilhafte Weiterbildungen und Ausgestaltungen sind Gegenstand der abhängigen Ansprüche.This object is achieved by a method according to claim 1 and by a system according to the independent claim. Advantageous developments and refinements are the subject of the dependent claims.

Wesentlich ist, 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.It is essential that baffles are installed in the space forming a suction area below the condenser system standing on support structures. As baffles walls for flow guidance, so-called wind deflectors, can be used.

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 11 (N - 2).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 these wind deflectors of the number of underlying modules depends. 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 11 (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 regard to the external fans, the walls "A" and "B" cause damming of the incoming air below the cooling air inlet of the fans and thus a better supply of air. Advantageously, this even uses the kinetic energy contained in the wind. Surprisingly, experiments have shown that the optimized arrangement of the wind deflectors produces no additional pressure loss for the fans, but on the contrary ensures a tendency to better supply the modules. Since the wind deflectors block approximately only the cross-sectional portion of the cooling air flow corresponds to the proportion of attributable to the modules cooling air flow, the modules located behind the barrier walls 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, further wind deflectors "C" are drawn in at a low height above the ground, which ensures better air admission of the modules located immediately behind the upper partitions "A" and "B". The height of this set up near the bottom wind deflector "C" is preferably 1 / N, maximum ¼ of the clear height of the support structure. The preferred ground clearance is about 1 m, but can also be increased to about 2 m with a corresponding size of the plant for easier inspection of the system. These bottom walls "C" provide an advantageous upward component to the cooling air flowing under the modules. The use of such ground-level wind deflectors depends on the local conditions, in particular 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 made in steel construction, but other materials such as canvas, plastics or wooden 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 movable attachment of the wind deflectors allows adaptation to the particular wind situation, especially the wind direction and the wind speed. The Adaptation of such movable walls can be done automatically or manually. Advantageously, the wind deflectors according to the invention can be carried out in sound-insulating materials, whereby the noise emission of the air-cooled condenser system can be further reduced.

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 according to the invention can be integrated not only in new constructions of air-cooled condenser systems but retrofitting of existing condenser systems is possible.
