Abstract
Es werden ein Verfahren und eine Vorrichtung zum Abkühlen eines einer Gasturbine zuzuführenden Luftstromes beschrieben.
Erfindungsgemäß wird der Luftstrom (1) vor der Zuführung in die Gasturbine (T) in einem Quench-Kühler (Q) gegen ein Kühlmedium (7) abgekühlt.
Hierbei wird als Kühlmedium (7) vorzugsweise Wasser verwendet.A method and a device for cooling an air stream to be fed to a gas turbine are described.
According to the invention, the air stream (1) is cooled against a cooling medium (7) in a quench cooler (Q) before being fed into the gas turbine (T).
Water is preferably used as the cooling medium (7).
Description
Die Erfindung betrifft ein Verfahren zum Abkühlen eines einer Gasturbine zuzuführenden Luftstromes.The invention relates to a method to cool down one to be fed to a gas turbine Air flow.
Ferner betrifft die Erfindung eine Vorrichtung zum Abkühlen eines einer Gasturbine zuzuführenden Luftstromes, aufweisend eine Zuführleitung, über die der Luftstrom der Gasturbine zugeführt wird.The invention further relates to a Cooling device an air flow to be fed to a gas turbine, having a feed line through which the Air flow fed to the gas turbine becomes.
Gattungsgemäße Verfahren und Vorrichtungen zum Abkühlen eines einer Gasturbine zuzuführenden Luftstromes dienen dem Zweck, die Effizienz der Gasturbine zu steigern. Diese Effizienzsteigerung ermöglicht es, der Gasturbine mehr Brennstoff zuzuführen, woraus wiederum eine Leistungssteigerung der Gasturbine resultiert.Generic methods and devices to cool down one to be fed to a gas turbine Air flow serve the purpose of increasing the efficiency of the gas turbine. This increase in efficiency enables it to supply more fuel to the gas turbine, which in turn is one Performance of the gas turbine results.
Gegenwärtig werden Gasturbinen mit Umgebungsluft versorgt, wobei diese Umgebungsluft vor der Zuführung einem Filter- sowie Lärmreduzierungssystem zugeführt wird. Es wurde bereits vorgeschlagen, den der Gasturbine zuzuführenden Luftstrom mittels unterschiedlicher Arten von Kühlkreisläufen abzukühlen; in der Summe führt diese doch nicht zu einer Steigerung der Effizienz des Gesamtprozesses. Zudem würden die verwendeten Wärmetauscher zu einem nicht erwünschten und kontraproduktiven Druckverlust des der Gasturbine zuzuführenden Luftstromes führen, wodurch ebenfalls die Effizienz der Gasturbine verringert würde.Gas turbines are currently being used Ambient air supplied, this ambient air before the supply Filter and noise reduction system supplied becomes. It has already been proposed to supply the gas turbine Cooling the air flow using different types of cooling circuits; in total this leads but not to increase the efficiency of the overall process. In addition, would the heat exchangers used to an unwanted one and counterproductive pressure loss of the gas turbine to be supplied Air flow, which would also reduce the efficiency of the gas turbine.
Aufgabe der vorliegenden Erfindung ist es, ein gattungsgemäßes Verfahren sowie eine gattungsgemäße Vorrichtung zum Abkühlen eines einer Gasturbine zuzuführenden Luftstromes anzugeben, das bzw. die die vorgenannten Nachteile vermeidet.Object of the present invention is a generic method and a generic device to cool down one to be fed to a gas turbine To specify airflow that avoids the aforementioned disadvantages.
Verfahrensseitig wird diese Aufgabe dadurch gelöst, dass der der Gasturbine zuzuführende Luftstrom vor der Zuführung in die Gasturbine in einem Quench-Kühler gegen ein Kühlmedium abgekühlt wird.On the procedural side, this task solved by that the one to be fed to the gas turbine Airflow before feeding into the gas turbine in a quench cooler against a cooling medium is cooled.
Vorrichtungsseitig wird die vorgenannte Aufgabe dadurch gelöst, dass in der Zuführleitung, der Gasturbine vorgeschaltet, ein Quench-Kühler angeordnet ist und diesem über eine Leitung ein Kühlmedium zuführbar ist.On the device side, the aforementioned is Task solved by that in the feed line, upstream of the gas turbine, a quench cooler is arranged and this via a Line a cooling medium supplied is.
Das erfindungsgemäße Verfahren, die erfindungsgemäße Vorrichtung sowie weitere Ausgestaltungen des- bzw. derselben seien im Folgenden anhand des in der Figur dargestellten Ausführungsbeispieles näher erläutert.The method according to the invention, the device according to the invention as well as further refinements of the same are in the following based on the embodiment shown in the figure.

Die Erfindung ermöglicht es, den einer Gasturbine zuzuführenden Luftstrom auf kostengünstige Weise zu kühlen und gleichzeitig zu reinigen. Sie stellt ferner sicher, dass der Druckverlust, den der zu kühlende Luftstrom erleidet, minimiert wird, woraus eine Erhöhung der Effizienz der Gasturbine resultiert.The invention enables that of a gas turbine supplied Airflow in an economical way to cool and clean at the same time. It also ensures that the Pressure loss that the one to be cooled Airflow suffers, is minimized, resulting in an increase in Efficiency of the gas turbine results.
