Description
Wärmetauscheranlage für Gasturbinen mit GasstrahlverdichterHeat exchanger system for gas turbines with gas jet compressor
und andere Gasturbinen Beschreibung Die Erfindung betrifft eine Wärmetauscheranlage für Gasturbinen mit Gasstrahlverdichter und andere Gasturbinen. In der Patentbeschreibung P 29 35 018.3 ist ein Wärmetauscher be-Schrieben, der den Nachteil hat, daß die zugeführte Luft vor der Verdichtung erwärmt wird, wodurch sich die erforderliche Kompressionsarbeit erhöht. Der Einbau des Wärmetauschers hinter dem Gasstrahlverdichter ist nicht möglich, da hier swischen dem Abgas und dem Arbeitsgas kein positives Temperatulgefälle besteht. and Other Gas Turbines Description The invention relates to a heat exchange system for gas turbines with gas jet compressors and other gas turbines. In the patent description P 29 35 018.3 is a heat exchanger be-described, which has the disadvantage that the supplied air is heated prior to compression, thereby increasing the required Compression work increased. The installation of the heat exchanger behind the gas jet compressor is not possible because there is no positive between the exhaust gas and the working gas There is a temperature gradient.
Die Erfindung hilft dem ITangel ab, indem ein oder mehrere offene Wärmetauscher-Turbinenkreise mit Druckluft versorgt werden,die, um einen Wärmeübergang zu ermöglichen in mehreren Oruckstufen nach unten gestaffelt ist. Dabei entspricht die niedrigste Druckstufe der niedrigsten Abgastemperatur.The invention helps the ITangel by creating one or more open Heat exchanger turbine circuits are supplied with compressed air, which in order to transfer heat to enable is staggered downwards in several pressure stages. This corresponds to the lowest pressure level of the lowest exhaust gas temperature.
Die vorgeschlagene Lösung des Problemes wird im folgendem beschrieben: Der Verdichter 1 saugt luft an und komrrimiert sie auf die niedrigste Druckstufe, die die Wärmetauscher 10 und 12 versorgt. Der Trerdichter 2 erhöht den druckwert und versorgt den Wärmetauscher 9. Der Gasstrahlverdichter 4, der durch den Stutzen 5 Luft ansaugt, wird mit nochmals erhöhtem Druck von dem Verdichter 3 versorgt.The proposed solution to the problem is described below: The compressor 1 draws in air and compresses it to the lowest pressure level, which supplies the heat exchangers 10 and 12. The hopper 2 increases the pressure value and supplies the heat exchanger 9. The gas jet compressor 4, which passes through the nozzle 5 air is sucked in, is supplied by the compressor 3 with a further increased pressure.
Da die Temperatur hinter dem GAsstrahlverdichter 4 wesentlich unter der für Gasturbinen üblichen Temperatur liegt, ist eine zusätzliche Brennkammer 6 zur Temperaturerhöhung vorgesehen.Since the temperature behind the gas jet compressor 4 is significantly below the temperature usual for gas turbines is an additional combustion chamber 6 intended to increase the temperature.
In dieser Brennkammer 6 wird dem sauerstoffreichem Luft-Abgasgemisch Brennstoff zugegeben und gezündet.In this combustion chamber 6 is the oxygen-rich air-exhaust gas mixture Fuel added and ignited.
Nachdem das heiße Abgas die Turbine 7, die die Arbeitsmaschine S antreibt, verlassen hat, wird es durch die Wärmetauscher 9 und 10 abgekühlt und nach Außen abgeleitet. Die im Wärmetauscher 9 übertragene Energie wird in der Turbine 11 zum eil in mechanische Arbeit umgewandelt.After the hot exhaust gas has passed the turbine 7, which drives the working machine S, has left, it is cooled by the heat exchangers 9 and 10 and to the outside derived. The energy transferred in the heat exchanger 9 is used in the turbine 11 for quickly converted into mechanical work.
Ein großer Teil der Restenergie wird vom Wärmetauscher 12 der Turbine 13 zugeführt. Das Abgas der Turbine 13 passiert, bevor es in das Freie gelangt, den Wärmetauscher 14 und gibt ebenso wie der Wärmetauscher 10 seine Energie an die Turbine 15 ab.A large part of the remaining energy is used by the heat exchanger 12 of the turbine 13 supplied. The exhaust gas from the turbine 13 passes before it is released into the open air, the heat exchanger 14 and, like the heat exchanger 10, gives its energy to the Turbine 15.
Die Turbinen 11, 13 und 15 treiben, außer den verdichtern 1,2 und 3, die Arbeitsmasschine 16 an.The turbines 11, 13 and 15 drive, except for the compressors 1, 2 and 3 3, the working machine 16 on.
Der Vorteil dieser Anordnung ist darin zu sehen, daß die Abgasenergie in Folge mehrerer Druckstufen der zugeführten Luft in len Wärmetauschern in mehreren Stufen abgebaut wird, daß nur die Wärmetauscher 9 und 10 den Verbrennungsgasen ausgesetzt sind, während durch die Wärmetauscher 12 und 14 nur erhitzte Luft geleitet wird, daß die Wärmetauscher nur niedrigen Drücken ausgesetzt sind unl entsprechend leicht gebaut werden können.The advantage of this arrangement is that the exhaust gas energy as a result of several pressure levels of the air supplied in len heat exchangers in several Stages is reduced that only the heat exchangers 9 and 10 exposed to the combustion gases while only heated air is passed through the heat exchangers 12 and 14, that the heat exchangers are only exposed to low pressures and are correspondingly easy can be built.
Falls größere Temperaturdifferenzen abzubauen sind, können in der gleichen Weise, wie beschrieben, mehrere Druckstufen und Wärmetauscher mit Turbinen angeordnet werden. Die Wärmetauscher werden im Gegenstromverfahren betrieben.If larger temperature differences need to be reduced, the same way as described, several pressure stages and heat exchangers with turbines to be ordered. The heat exchangers are operated in a countercurrent process.
Wird eine Turbine mit der beschriebenen Wärmetauscheranlage in einem Feizkraftwerk eingesetzt, so besteht die Möglichkeit, das durch die Wärmetauscher 12 und 14 geleitete Gas in nachgeschalteten Kühlern, die zur Erhitzung des Wassers dienen abzukühlen, danach zu verdichten und wieler den Wärmetauschern zuzuführen. Bei dieser Methode ist ein geschlossener Kreislauf vorhanden, ler mit einem Schutzgas zur Verhinderung von Korrosion gefüllt sein kann. tusserlemist auf diese Art kein Ansaufgilter vor dem Verdichter notwendig. Die Verdichter müssen für diese Methode in geeigneter Weise in den Wärmetauscher -Turbinenkreis eingebaut werden.If a turbine with the heat exchanger system described in one Feizkraftwerk used, so there is the possibility of this through the heat exchanger 12 and 14 conducted gas into downstream coolers that are used to heat the water serve to cool down, then to compress and how to supply the heat exchangers. With this method there is a closed circuit, ler with a protective gas can be filled to prevent corrosion. tusserlemist in this way no An intake filter is necessary in front of the compressor. The compressors need to use this method be installed in a suitable manner in the heat exchanger turbine circuit.
