Description
Die Erfindung betrifft eine Kondensationsanlage mit den Merkmalen im Oberbegriff des Patentanspruchs 1.The The invention relates to a condensation plant with the features in Preamble of claim 1.
Insbesondere bei größeren Kraftwerkseinheiten und bei Gebäuden im unmittelbaren Nahbereich luftgekühlter Kondensationsanlagen muss bei ungünstigen Windverhältnissen zum Teil mit deutlicher Warmluftrezirkulation gerechnet werden. Die Warmluftrezirkulation findet in begrenzten Bereichen, insbesondere in den Eckbereichen einer Kondensationsanlage statt. Die naheliegendste Lösung wäre es, die Höhe der die Wärmetauscherelemente umgebenden Windschutzwände zu erhöhen. Grundsätzlich wäre dies nur in den kritischen Bereichen erforderlich. Kostengründe, die Statik der Kondensationsanlage sowie Umweltauflagen und wechselnde Intensitäten der Warmluftrezirkulation sprechen jedoch gegen diese Vorgehensweise und verlangen nach einer kostengünstigeren und effektiven Maßnahme, um auch temporär, das heißt nur bei konkretem Vorliegen des tatsächlichen Problems die Warmluftrezirkulation zu verringern.Especially for larger power plant units and in buildings in the immediate vicinity of air-cooled condensation plants must be at unfavorable wind conditions be expected in part with significant warm air recirculation. The warm air recirculation takes place in limited areas, in particular in the corner areas of a condensation plant instead. The most obvious solution it would be that height of the heat exchanger elements surrounding windbreak walls to increase. Basically, this would be only needed in the critical areas. Cost reasons, the Statics of the condensation plant as well as environmental regulations and changing intensities the warm air recirculation speak against this approach and ask for a cheaper one and effective action, also temporary, this means only in the case of the actual problem of the hot air recirculation to reduce.

Da das Problem der Warmluftrezirkulation stark von der vorherrschenden Windrichtung und den lokalen Windgeschwindigkeiten abhängig ist, stellt eine ausschließlich als aerodynamische Wand ausgebildete Barriere einen hohen apparativen Aufwand dar, der keineswegs an allen Randbereichen einer Kondensationsanlage zwingend erforderlich ist. Auch wenn es grundsätzlich möglich ist, einen Teil des Randbereichs der Kondensationsanlage mit einer aerodynamischen Wand zu versehen, ist es aufgrund der Änderung der Windverhältnisse schwierig vorherzusehen, ob nicht temporär auch andere Abschnitte des Randbereichs von erhöhter Warmluftrezirkulation betroffen sind. Ein schnelles Umrüsten ist in einem solchen Fall nicht möglich. Vorsorglich müsste man den gesamten Randbereich mit einer aerodynamischen Wand ausrüsten, was allerdings aus Kostengründen nicht sinnvoll ist.There the problem of hot air recirculation is greatly different from the prevailing one Wind direction and local wind speeds, Represents one exclusively designed as aerodynamic barrier barrier a high apparatus Expenditure is by no means at all peripheral areas of a condensation plant is mandatory. Although it is possible in principle, a part of the edge area to provide the condensation plant with an aerodynamic wall, it is because of the change the wind conditions difficult to foresee, whether temporarily not other sections of the Border area of elevated Warm air recirculation are affected. A quick changeover is not possible in such a case. As a precaution you have to Equip the entire edge area with an aerodynamic wall, which but for cost reasons does not make sense.
Hiervon ausgehend liegt der Erfindung die Aufgabe zugrunde, eine Kondensationsanlage mit einer aerodynamischen Wand bereitzustellen, die ohne große bauliche Veränderungen im Bedarfsfall zumindest bereichsweise zuschaltbar ist.Of these, Based on the object of the invention, a condensation plant to provide with an aerodynamic wall, without great structural changes if necessary, at least partially switchable.
Diese Aufgabe ist bei einer Kondensationsanlage mit den Merkmalen des Patentanspruchs 1 gelöst.These Task is with a condensation plant with the characteristics of Patent claim 1 solved.
Vorteilhafte Weiterbildungen des Erfindungsgedankens sind Gegenstand der Unteransprüche.advantageous Further developments of the inventive concept are the subject of the dependent claims.
Die erfindungsgemäße Kondensationsanlage weist an ihrem Rand eine aus Plattenelementen aufgebaute Windschutzwand auf, wobei die Plattenelemente eine Vielzahl von sich in Hochrichtung erstreckenden Hohlkammern aufweisen. Die Hohlkammern dieser Windschutzwand werden dafür genutzt, einen Luftstrom zur Schaffung einer aerodynamischen Wand oberhalb der Windschutzwand auszubilden. Der wesentliche Vorteil der erfindungsgemäßen Kondensationsanlage ist, dass keine zusätzlichen Schlitzdüsen oder aufwendige Düsenschächte installiert werden müssen, da die ohnehin vorhandene Windschutzwand zur Ausbildung einer aerodynamischen Wand genutzt wird.The inventive condensation plant has at its edge a constructed of plate elements windbreak wall on, wherein the plate elements a plurality of themselves in the vertical direction having extending hollow chambers. The hollow chambers of this windbreak wall be for it used an airflow to create an aerodynamic wall form above the windbreak wall. The main advantage the condensation plant according to the invention is that no additional slot nozzles or elaborate nozzle shafts installed Need to become, because the already existing windbreak wall to form an aerodynamic Wall is used.
Der eingeleitete Luftstrom ist insbesondere ein Kaltluftstrom, der sich mit der erwärmten Kühlluft vermengt und allein aufgrund der Vermengung die negativen Auswirkungen der verbleibenden Warmluftzirkulation mindert. Numerische Überprüfungen ergaben bei geeigneten Geschwindigkeiten des Luftstroms eine deutliche Reduzierung der lokalen Warmluftrezirkulationsrate um einige Prozentpunkte. Dies führt zu einer Verbesserung der Kondensationsleistung und damit zu einer Steigerung des Kraftwerkwirkungsgrads. Die Förderung des beschleunigten Luftstroms kann mit einem separaten, z.B. mit einem mobilen Gebläse erfolgen oder auch durch Abzweigen eines Teilstroms von den Kühlluft fördernden Ventilatoren, welche den randseitigen Wärmetauscherelementen zugeordnet sind. Aufgrund des relativ geringen Querschnitts der Hohlkammern würde zwar ein Druckverlust entstehen, allerdings ist die Förderleistung der Ventilatoren sehr hoch, so dass der Volumenstrom im Bereich der aerodynamischen Windwand relativ hoch ist und die Druckverluste kompensiert. Durch Nutzung der vorhandenen Windschutzwände lässt sich temporär und auch dauerhaft eine flexible und gleichzeitig effektive Lösung zur Reduzierung der Warmluftrezirkulation mit relativ geringem technischem Aufwand und auch mit geringen Kosten erreichen.Of the introduced air flow is in particular a cold air flow, which is with the heated Cooling air mixed and just because of the blending the negative effects of remaining warm air circulation reduces. Numerical checks showed at suitable speeds of the air flow, a significant reduction the local warm air recirculation rate by a few percentage points. This leads to an improvement of the condensation performance and thus to a Increase in power plant efficiency. The promotion of accelerated Airflow may be provided with a separate, e.g. done with a mobile fan or by branching a partial flow of the cooling air promotional Fans associated with the peripheral heat exchanger elements are. Due to the relatively small cross section of the hollow chambers would indeed a pressure loss arise, however, is the flow rate of the fans very high, so that the volume flow in the area of the aerodynamic wind wall is relatively high and compensates for the pressure losses. By use the existing windbreak walls let yourself temporary and also permanently a flexible and at the same time effective solution to Reduction of warm air recirculation with relatively little technical Effort and achieve low cost.
