  Verfahren zur Wiedergewinnung der   Wärme   ans dem Abdampf wenig belasteter oder leer laufender   Reservemaschinen.   



   In elektrischen Zentralen lässt man häufig Reservemaschinen als Phasenschieber gekuppelt mit der Kraftmaschine leer mitlaufen, da es zumeist schwierig oder, wie z. B. bei Dreilageranordnung,   unmög-   lich ist, den Generator von der Kraftmaschine abzukuppeln. Der Leerlaufdampf der   Reservemaschine   geht dann im Kühlwasser verloren. 



   Dieser Verlust kann vermieden werden, wenn erfindungsgemäss das Kondensat der Hauptmaschine, welche   11Ìcht   voll belastet ist, durch den Kondensator der   Reservemaschine   oder durch einen besonderen Hilfskondensator geleitet wird, so dass der   Lserlaufdampf   der Reservemaschine zur   Speisewasservorwärmung   ausgenutzt wird. Dabei kann man den Kondensator oder den Hilfskondensator der Reservemasehine an die Luftpumpe der Hauptmaschine anschliessen. Wird ein Hilfskondensator bei der   Reseivemaschine   verwendet, so darf man das Kühlwasser für ihren Hauptkondensator nicht ganz abstellen, damit er nicht zu heiss wird. Das Vakuum muss jedoch für den Hilfskondensator so eingestellt werden, dass ihm der Dampf zuströmt.

   Es ist auch möglich, den Hilfskondensator nicht hinter der leerlaufenden Maschine, sondern an eine Vorstufe anzuschliessen. 



   Das Verfahren nach der Erfindung ist auch anwendbar, wenn es sich nicht darum handelt, mit der Reservemaschine einen Phasenschieber zu betreiben, sondern wenn man, wie es besonders bei grossen Einheiten erwünscht ist, während der Zeit geringer Belastung alle Maschinen laufen lassen will. Man kann dann das Kondensat der belasteten Maschinen zum Niederschlagen des Dampfes der leerlaufenden Maschinen verwenden oder, wenn sämtliche Maschinen zeitweise leer laufen, das Kondensat aller   Ma-   schinen während der Zeit der vollen Belastung speichern und damit den Dampf sämtlicher Maschinen in der Zeit geringer Belastung oder des Leerlaufes niederschlagen. Das hiedurch um einige Grad erwärmte Kondensat kann dann in einem anderen Speicher für die Zeit der   Vollbelastung   aufbewahrt werden. 



   PATENT-ANSPRÜCHE :
1. Verfahren zur Wiedergewinnung der Wärme aus dem Abdampf wenig belasteter oder leer laufender Reservemaschinen, dadurch gekennzeichnet, dass das Kondensat der belasteten Maschinen zum Niederschlagen des Dampfes der schwach belasteten Maschinen verwendet wird, um diesen Dampf für die   Spsisewasservorwälmung   nutzbar zu machen.

  Process for the recovery of the heat from the reserve machines which are not very polluted or which are idling.



   In electrical centers, reserve machines can often be used as phase shifter coupled with the prime mover because it is usually difficult or, as is the case, for example. B. in a three-bearing arrangement, it is impossible to decouple the generator from the engine. The idle steam of the reserve machine is then lost in the cooling water.



   This loss can be avoided if, according to the invention, the condensate of the main machine, which is fully loaded, is passed through the condenser of the reserve machine or through a special auxiliary condenser, so that the steam from the reserve machine is used to preheat the feed water. You can connect the capacitor or the auxiliary capacitor of the reserve machine to the air pump of the main engine. If an auxiliary condenser is used in the reserve machine, the cooling water for the main condenser must not be turned off completely so that it does not get too hot. However, the vacuum for the auxiliary condenser must be set so that the steam flows to it.

   It is also possible to connect the auxiliary capacitor not behind the idling machine, but to a preliminary stage.



   The method according to the invention can also be used if it is not a question of operating a phase shifter with the reserve machine, but rather if, as is particularly desirable in the case of large units, one wants to run all machines during the period of low load. The condensate of the loaded machines can then be used to precipitate the steam of the idling machines or, if all machines run temporarily empty, the condensate of all machines can be stored during the time of full load and thus the steam of all machines in the time of low load or of idling. The condensate, which has been warmed up by a few degrees, can then be stored in another storage tank for the duration of the full load.



   PATENT CLAIMS:
1. A method for recovering heat from the exhaust steam of slightly loaded or idling reserve machines, characterized in that the condensate of the loaded machines is used to precipitate the steam of the lightly loaded machines in order to make this steam usable for the Spsisewasservorwälmung.
