Abstract

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Durchführung des Verfahrens zur Wirkungsgradverbesserung in Dampfkraftwerken mit einer Dampfturbinenanlage mit Teilturbinen, deren zugeordnete Teilkondensatoren 3a und 3b in einer Hauptkondensatoranlage 3 zusammengefaßt und kühlwasserseitig in Reihe geschaltet sind.The invention relates to a method and a device to carry out the efficiency improvement process in steam power plants with a steam turbine system with partial turbines, the associated partial capacitors 3a and 3b combined in a main capacitor system 3 and are connected in series on the cooling water side.

Sie ist dadurch gekennzeichnet, daß einzelnen oder allen aus den Teilkondensatoren austretenden Kühlwasserströmen 9 und ggf. 8 vor Eintritt in den nachfolgenden Teilkondensator 3b zusätzliches Kühlwasser 7 und ggf. 10 und 11 beigemischt wird und das beigemischte Kühlwasser vollständig oder teilweise aus dem Hauptkühlwasserstrom 2 der Kühlwasserpumpe 1 vor Eintritt in die Hauptkondensatoranlage 3 abgezweigt wird.It is characterized in that individual or all Cooling water flows emerging from the partial condensers 9 and possibly 8 before entering the subsequent partial capacitor 3b additional cooling water 7 and possibly 10 and 11 is added and the admixed cooling water completely or partially from the main cooling water stream 2 of the cooling water pump 1 before entering the main condenser system 3 is branched off.

Die Erfindung beinhaltet weiter, daß die vom Hauptkühlwasserstrom 2 vor Eintritt in die Hauptkondensatoranlage 3 abgezweigten Kühlwasserteilströme z. B. 7 und 10 während der bypassartigen Umfahrung eines oder mehrerer Teilkondensatoren z. B. 3a zumindest vereinzelt an einem Wärmeaustausch - z. B. in einem Nebenkühlwassersystem 4 - beteiligt sind und dadurch die Wärmeaufnahme- und Wärmetransportkapazität für den notwendigen Wärmeabstrom erhöht wird.

Figure 00000001
The invention further includes that the branched from the main cooling water stream 2 before entering the main condenser system 3 cooling water streams z. B. 7 and 10 during the bypass-like bypassing one or more partial capacitors z. B. 3a at least occasionally at a heat exchange - z. B. in a secondary cooling water system 4 - are involved and thereby the heat absorption and heat transport capacity for the necessary heat flow is increased.
