Description
Die Erfindung betrifft eine Heißluft- oder Gasturbinenanlage mit Abwärmeverwertung. Sie besteht darin, daß die durch Kühlung des Arbeitsmittels anfallende Wärme in Anpassung an den jeweiligen Wärmebedarf der Anlage eingestellt wird.The invention relates to a hot air or gas turbine system with waste heat recovery. It consists in the fact that the heat generated by cooling the working fluid is in Adjustment to the respective heat demand of the system is set.
Der Betrieb der Anlage und deren Wirkungsweise geht aus dem Diagramm hervor.The operation of the system and its mode of operation can be seen from the diagram emerged.
Punkt A: Ansaugen der Luft bzw. des Arbeitsmittels, Strecke AB: Verdichtung (Niederdruck), B C: Abkühlen der Luft mit Wärmeausnutzung, z. B. für Heizzwecke, CC: Abkühlen der Luft durch Frischwasser, CD. Nochmalige Verdichtung der Luft (Hochdruck), DE: Wärmezufuhr im Regenerativaustausch (JKnach DE), E F: Wärmezufuhr im Lufterhitzer, FG: Expansion (Hochdruck), GH: Nochmalige Erhitzung der Luft (Zwischenerhitzung, Niederdruck), HJ: Expansion (Niederdruck), J K: Wärmeabgabe im Regenerativverfahren (JK nach, DE), KA': Rückkühlung der Luft mit Wärmeabgabe für Nutzzwecke, A'A: Weitere Rückkühlung der Luft durch Frischwasser. Die Anlage kann auch mit ein- oder mehrstufiger Verdichtung mit Zwischenkühlung und auch mit mehrstufiger Entspannung mit oder ohne Zwischenerhitzung arbeiten.Point A: Sucking in the air or the working medium, route AB: Compression (low pressure), B C : Cooling the air with heat utilization, e.g. B. for heating purposes, CC: cooling the air with fresh water, CD. Repeated compression of the air (high pressure), DE: heat supply in regenerative exchange (JK to DE), EF: heat supply in the air heater, FG: expansion (high pressure), GH: repeated heating of the air (intermediate heating, low pressure), HJ: expansion (low pressure), JK: heat release in the regenerative process (JK after, DE), KA ': recooling of the air with heat dissipation for useful purposes, A'A: further recooling of the air with fresh water. The system can also work with single or multi-stage compression with intermediate cooling and also with multi-stage expansion with or without intermediate heating.
Zur Regelung der nutzbar verwendeten Wärme wird die Änderung der Frischwasserzufuhr herangezogen. Die Frischwasserkühlung kann durch Frischwassermengenänderung stetig geregelt werden, und zwar so, daß nach Bedarf die Temperatur vor den Verdichtern beliebig geändert wird. Die Wärmeabgabe für Nutzzwecke kann hierdurch in gewissen Grenzen bei praktisch konstanter oder wenn notwendig veränderlicher Lufterhitzerbelastung geregelt werden.The change in the fresh water supply is used to regulate the usable heat used used. The fresh water cooling can be increased continuously by changing the fresh water quantity can be regulated, in such a way that, if necessary, the temperature upstream of the compressors is changed at will. The heat output for useful purposes can thereby in certain Limits with practically constant or, if necessary, variable air heater load be managed.
Das Diagramm A'B'C'D'EFGHJK'A' zeigt als Beispiel dieser Betriebsart den Betrieb ohne Frischwasserkühlung, das Diagramm A" B" C" D" E F G H J K"A" derselben Zeichnung ein Beispiel des Betriebes mit gedrosselter Frischwasserkühlung. Weiterhin kann die Wärmeabgabe für Nutzzwecke dadurch geregelt werden, daß die Anlage nach dem DiagrammABCDEFGHJKA unter Beibehaltung konstanter Temperatur vor den Verdichtern und Veränderung der Temperatur zwischen Nutz- und Frischwasserkühler, z. B. durch Verändern der Heiz- und Frischwassermenge, bei konstanter bzw. veränderlicher Lufterhitzerhelastung und Abgabe der Energie an der Kupplung der Anlage ausgefahren wird.The diagram A'B'C'D'EFGHJK'A 'shows the operation without fresh water cooling as an example of this operating mode, the diagram A "B" C "D" EFGH J K "A" of the same drawing shows an example of the operation with throttled fresh water cooling. Furthermore, the heat output for useful purposes can be regulated that the system according to the diagram ABCDEFGHJKA while maintaining a constant temperature in front of the compressors and changing the temperature between the utility and fresh water cooler, z. B. by changing the amount of heating and fresh water, with constant or variable air heater load and output of the energy to the coupling of the system is extended.
Die Erfindung kann bei Heißluftturbinen und bei Gasturbinen mit geschlossenem, halbgeschlossenem wie auch offenem Kreislauf angewendet werden.The invention can be used in hot air turbines and in gas turbines with closed, semi-closed as well as open circuit can be used.
