Title
(DE) GASTURBINE UND VERFAHREN ZUM BETREIBEN DERSELBEN
(EN) GAS TURBINE AND METHOD FOR OPERATING THE SAME
(FR) TURBINE A GAZ ET PROCEDE POUR LA FAIRE FONCTIONNER
Abstract
(DE) Es werden ein Verfahren zum Betreiben einer Gasturbine und eine Gasturbine (1) vorgeschlagen, wobei ein in der Turbine (4) der Gasturbine (1) entspanntes Arbeitsgas zur Vorwärmung des zu erhitzenden Arbeitsgases verwendet wird. Ein höherer Wirkungsgrad ist dadurch erreichbar, daß ein Verdichter (2) anstelle einer Erhöhung des Eingangsdrucks des Arbeitsgases eine Druckabsenkung auf der Abströmseite der Turbine (4) erzeugt und Wasser aus dem entspannten Arbeitsgas vor dem Verdichten abgeschieden wird.
(EN) The invention relates to a gas turbine (1), and to a method for operating said gas turbine. According to the invention, an industrial gas which has expanded in the turbine (4) of the gas turbine (1) is used for preheating the industrial gas to be heated. The aim of the invention is to achieve a greater degree of efficiency. To this end, a compressor (2) causes the pressure to decrease on the off-flow side of the turbine (4) instead of increasing the supply pressure of the industrial gas, and water from the expanded industrial gas is separated off before compression.
(FR) L'invention concerne un procédé permettant de faire fonctionner une turbine à gaz, ainsi qu'une turbine à gaz (1). Selon l'invention, un gaz de travail, détendu dans la partie turbine (4) de la turbine à gaz (1), est utilisé pour le préchauffage du gaz de travail à chauffer. On obtient un degré d'efficacité plus élevé par le fait qu'un compresseur (2), au lieu de produire une élévation de la pression d'entrée du gaz de travail, produit une baisse de pression sur le côté de la sortie de flux de la partie turbine (4), et que l'eau est séparée du gaz de travail détendu avant la compression.
