Abstract

The closed gas turbine process involves processing heat loss of isothermal compressor (C2) through heat exchangers (WT1,WT2), which are arranged in inlet of low-pressure compressor (C1). A turbine section is formed opposite to the inlet in the low-pressure compressor in such a manner that large-volume of working fluid is formed.

Description

Dieses Patent behandelt den geschlossenen Gasturbinen-Prozess, der in dem Patent No.: DE 10 2005 060 831 B4 beschrieben ist. Ausgehend von dieser Patentschrift werden hier nun folgende Ergänzungen dazu erstellt.This patent deals with the closed gas turbine process described in the patent No .: DE 10 2005 060 831 B4 is described. Starting from this patent, the following additions are created here now.

Die Verlustwärme des Isotherm-Kompressors C2 (siehe Bild No.: 1 und 2) wird in dem angegebenen Patent in die Atmosphäre abgeleitet. Dadurch entsteht eine Abhängigkeit zum Temperaturniveau der Luft. Die Antriebsleistung des Isotherm-Kompressors C2 ist direkt abhängig von der Temperatur des Rückkühl-Mittels und nimmt mit sinkender Temperatur ab. Die Verluste des Isotherm-Kompressors werden hier in die Atmosphäre ableitet.The Heat loss of the isothermal compressor C2 (see picture No .: 1 and 2) is in the specified patent in the atmosphere derived. This creates a dependence on the temperature level of Air. The drive power of the isothermal compressor C2 is direct depending on the temperature of the recooling agent and decreases with decreasing temperature. The losses of the isothermal compressor are derived here into the atmosphere.

Wird die Antriebsleistung des Isotherm-Kompressors C2 gesenkt, dann wird die Nutzleistung des geschlossenen Gasturbinen-Prozesses erhöht. Um nun dieses zu erreichen, wird hier vorgesehen, dass diese Verlustwärme dem Arbeitsmedium des geschlossenen Gasturbinen-Prozess wieder zugeführt wird. Dazu dient der Wärmetauscher WT2, der vor dem Eintritt des Arbeitsmediums in den Niederdruck-(Isentrop-)Kompressor C1 angeordnet ist. Damit wird der ganze Prozess unabhängig von der Atmosphären-Temperatur und ermöglicht eine niederere Betriebstemperatur des Isotherm-Kompressors, dessen Antriebsleistung sich reduziert.Becomes the drive power of the isothermal compressor C2 is lowered, then increases the net power of the closed gas turbine process. In order to achieve this now, it is provided that this heat loss the working medium of the closed gas turbine process is supplied again. The purpose of the heat exchanger WT2, before the entrance of the working medium in the low-pressure (isentropic) compressor C1 arranged is. This makes the whole process independent of the atmospheric temperature and allows a lower operating temperature of the isothermal compressor, whose Drive power is reduced.

Gleichzeitig steigt aber die Eintrittstemperatur des Arbeitsmediums in den Niederdruck-Kompressors C1, wodurch dessen Antriebsleistung ansteigt. Es wird hier unterstellt, dass die Summe den Antriebsleistungen der zwei Kompressoren sich aber reduziert. Aber auch die Austrittstemperatur des Niederdruck-Kompressors C1 erhöht sich, wodurch sich die Temperatur des Arbeitsmediums am Austritt des Wärmetauschers WT1 entsprechend erhöht und damit die erforderliche zuzuführende Wärmemenge reduziert, die notwendig ist um eine vorgegebene Turbineneintrittstemperatur zu erreichen.simultaneously but increases the inlet temperature of the working medium in the low-pressure compressor C1, whereby its drive power increases. It is assumed here that the sum of the drive powers of the two compressors themselves but reduced. But also the outlet temperature of the low-pressure compressor C1 increases, which increases the temperature of the working fluid correspondingly increased at the outlet of the heat exchanger WT1 and thus the required amount of heat to be supplied reduced, which is necessary to a predetermined turbine inlet temperature to reach.

Die beigefügten Bilder No.: 1 und 2 zeigen zwei Schaltungen, die dieses Verfahren nutzen. In Bild No.: 1 ist eine Ein-Wellenanlage gezeigt. Der Isotherm-Kompressor C2 wird sicherlich eine andere Drehzahl zum optimalen Betrieb verlangen. Damit ergibt sich die Schaltung nach Bild No.: 2. Hier wird der Isotherm-Kompressor elektrisch mit optimaler Drehzahl angetrieben.The attached pictures No .: 1 and 2 show two circuits, who use this procedure. In picture No .: 1 is a single shaft system shown. The isothermal compressor C2 will certainly be a different speed to demand optimal operation. This results in the circuit after picture No .: 2. Here is the isothermal compressor with electric driven at optimum speed.

Der Turbinenaustritt mit dem großvolumigen Arbeitsmedium ist direkt gegenüber dem Eintritt in den Niederdruck-Kompressor angeordnet, sodass weite, verlustbehaftete Wege vermieden werden.Of the Turbine outlet with the large-volume working medium is directly opposite the entrance to the low pressure compressor arranged so that long, lossy paths are avoided.
