   Verfahren zur Speicherung von Wärme bei Heizkraftwerken über den Rücklauf des Umwälzwassers zur Beeinflussung des Dampfdurchsatzes einer Turbine 
 EMI1.1 
 

 <Desc/Clms Page number 2> 

 V ist der Vorlauf und R der Rücklauf des Umwälzwasserkreislaufes, T die Turbine des Heizkraftwerkes und G der Generator. Alle übrigen Symbole ohne Bezeichnung bedeuten die an sich bekannten Anlageteile eines Heizkraftwerkes. 



   Erfindungsgemäss wird nun in Betriebszeiten, in denen eine künstliche Vergrösserung der Heizdampfmenge gewollt ist,   z. B.   tags, der Rücklauf des Umwälzwassers vor Passieren der Heizeinrichtung H des Lagerbehälters L im Zusatz-Wärmeaustauscher ZW erstmalig aufgewärmt, gibt in der Heizeinrichtung H   Wärme an den Lagervorrat ab und wird im Haupt-Wärmeaustauscher   HW wieder auf die gewünschte Vorlauftemperatur aufgeheizt.

   In Betriebszeiten dagegen, in denen eine künstliche Verringerung der Heizdampfmenge gewollt ist, etwa nachts, wird die Heizmittelzufuhr zum Zusatz-Wärme-Austauscher ZW   abgestellt, der damit kalt bleibende Umwälzwasserrücklauf nimmt in der Heizeinrichtung   H gespeicherte Wärme aus dem Ölvorrat des Lagerbehälters auf und bedarf nur mehr einer Restaufheizung auf die gewünschte Vorlauftemperatur im Haupt-Wärmeaustauscher HW. 



   Im Schaltschema dargestellt ist eine reine Gegendruckanlage. In sinngemäss gleicher Weise ist der 
 EMI2.1 
 
Entnahme-Kondensationsanlage, sowie die Anlage nach dem bekann-aus der Heizdampfleitung gespeist. 



   Ferner ist von der Erfindung unberührt die vorzusehende Beheizung der tiefsten Behälterschicht, um das dicke Öl pumpfähig zu machen.

   Process for storing heat in thermal power stations via the return of the circulating water to influence the steam throughput of a turbine
 EMI1.1
 

 <Desc / Clms Page number 2>

 V is the flow and R the return of the circulating water circuit, T the turbine of the thermal power station and G the generator. All other symbols without a designation mean the system parts of a thermal power station which are known per se.



   According to the invention, in operating times in which an artificial increase in the amount of heating steam is desired, z. B. during the day, the return of the circulating water before passing the heater H of the storage tank L in the additional heat exchanger ZW warmed up for the first time, gives off heat to the storage supply in the heater H and is heated again to the desired flow temperature in the main heat exchanger HW.

   On the other hand, during operating times in which an artificial reduction in the amount of heating steam is desired, e.g. at night, the heating medium supply to the additional heat exchanger ZW is switched off, and the circulating water return, which thus remains cold, absorbs the heat stored in the heating device H from the oil supply of the storage tank and is only required more of a residual heating to the desired flow temperature in the main heat exchanger HW.



   A pure counter-pressure system is shown in the circuit diagram. In analogous manner is the
 EMI2.1
 
Extraction condensation system, as well as the system after being fed from the heating steam line.



   Furthermore, the heating of the deepest container layer to be provided in order to make the thick oil pumpable is not affected by the invention.

PATENTANSPRUCH : Verfahren zur Speicherung von Wärme bei Heizkraftwerken über den Rücklauf des Umwälzwassers zur Beeinflussung des Dampfdurchsatzes einer Turbine, dadurch gekennzeichnet, dass in Betriebszeiten eines gewollten höheren Durchsatzes der Turbine mit dem in einem Zusatz-Wärmeaustauscher im Rücklauf aufgeheizten Umwälzwasser ein Heizölvorrat grösseren Ausmasses in einem Lagerbehälter aufgeheizt wird und dass in Betriebszeiten eines gewollten verringerten Durchsatzes bei abgestelltem ZusatzWärmeaustauscher das abgekühlte Umwälzwasser von dem im Lagerbehälter vorhandenen Heizölvorrat aufgeheizt wird. PATENT CLAIM: Method for storing heat in thermal power stations via the return of the circulating water to influence the steam throughput of a turbine, characterized in that during operating times of a desired higher throughput of the turbine with the circulating water heated in an additional heat exchanger in the return, a larger amount of heating oil is heated in a storage tank and that in operating times of a desired reduced throughput when the additional heat exchanger is switched off, the cooled circulating water is heated by the fuel oil supply in the storage tank.
