  Verfahren zum Überhitzen von Zwischendampf. 



   Es ist bekannt, hochgespannten Dampf in einem Betriebskessel dadurch zu erzeugen, dass man das Wasser des Betriebskessels durch überhitzten oder gesättigten hochgespannten Dampf mittelbar oder unmittelbar erhitzt. Ferner ist es bekannt, den Zwischenüberhitzer zwischen der   Hochdruckstufe   und der Niederdruckstufe einer Maschine durch Dampf zu beheizen, der in dem Betriebskessel oder in einem besonderen Dampfkessel erzeugt ist.

   Um demgegenüber eine höhere   Überhitzung   zu gewinnen, besteht das Verfahren gemäss der Erfindung darin, dass der Dampf, welcher als mittelbares Heizmittel zur Zwischen- überhitzung dient, dem hochgespannten Heizdampf für den Betriebskessel vor dessen Einführung in letzteren entnommen wird0
Die Zeichnung zeigt ein Ausführungsbeispiel zur Erläuterung des Verfahrens in schematischer Darstellung. a ist der Betriebsdampferzeuger, in welchem beispielsweise Betriebsdampf von 60   Atm.   für die Hochdruckstufe h der Dampfmaschine erzeugt wird. b ist der Heizdampferzeuger, in welchem Heizdampf von etwa 100-120 Atm. erzeugt wird, der, nach dem Beispiel mittelbar in einem geschlossenen System umlaufend, den Betriebsdampf erzeugt.

   Der Zwischenüberhitzer d enthält eine Heizschlange e, deren Zuleitung von der Leitung des Heizdampferzeugers b vor der Einführung des Heizdampfes in den Betriebskessel   a   abgezweigt ist. Eine Pumpe p fördert den Dampf,   der seine Heizwärme   in dem Zwischenüberhitzer abgegeben hat, in den Heizdampferzeuger b zurück.

   Hiedurch kann der Zwischendampf zwischen der   Hochdruckstufe A   und der   Niederdruckstufe n   auf etwa   300  und darüber   überhitzt werden. e ist ein hinter dem Heizdampferzeuger b in den   Rauchgaszug   eingeschalteter Überhitzer für den Betriebsdampf, um diesen auf etwa   4500 zu Überhitzen.   Der Betriebskessel a kann in bekannter Weise von den Abgasen des Heizdampferzeugers mit beheizt werden, oder er kann in bekannter Weise gegen diesen isoliert sein oder auch in gleichfalls bekannter Weise an vom Heizdampferzeuger getrennter Stelle angeordnet sein. Der im Heizdampferzeuger b erzeugte Dampf kann gesättigter oder überhitzter Dampf sein.

  Process for superheating intermediate steam.



   It is known to generate high-pressure steam in an operating boiler by directly or indirectly heating the water in the operating boiler by means of superheated or saturated high-tension steam. It is also known to heat the reheater between the high pressure stage and the low pressure stage of a machine by means of steam which is generated in the operating boiler or in a special steam boiler.

   In order to achieve a higher level of superheating, the method according to the invention consists in that the steam, which serves as an indirect heating medium for intermediate superheating, is taken from the high-pressure heating steam for the operating boiler before it is introduced into the latter
The drawing shows an exemplary embodiment for explaining the method in a schematic representation. a is the operating steam generator in which, for example, operating steam of 60 atm. is generated for the high pressure stage h of the steam engine. b is the heating steam generator in which heating steam of about 100-120 atm. is generated, which, according to the example, indirectly circulating in a closed system, generates the operating steam.

   The reheater d contains a heating coil e, the feed line of which is branched off from the line of the heating steam generator b before the heating steam is introduced into the operating boiler a. A pump p conveys the steam, which has given off its heat in the reheater, back into the heating steam generator b.

   As a result, the intermediate steam between the high pressure stage A and the low pressure stage n can be superheated to around 300 and above. e is a superheater for the operating steam, which is switched into the flue gas duct behind the heating steam generator b in order to superheat it to around 4500. The operating boiler a can be heated in a known manner by the exhaust gases of the heating steam generator, or it can be insulated from this in a known manner or also be arranged in a likewise known manner at a point separate from the heating steam generator. The steam generated in the heating steam generator b can be saturated or superheated steam.
