Description

Verfahren zum Überhitzen von Zwischendampf. Es ist bekannt, hochgespannten: Dampf in einen 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 Zwischenüberbitzer 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,. Er-. findung darin, da.ß der Dampf, welcher als mittelbares Heizmittel zur Zwischenüberhitzung dient, dern hochgespannten Heizdampf für den Betriebskessel vor dessen Einführung in letzteren entnommen wird.Process for superheating intermediate steam. It is known to be highly stressed: Steam in a plant boiler by: generating that by using the water of the plant boiler directly or indirectly through superheated or saturated high-pressure steam heated. It is also known to place the intermediate superboiler between the high pressure stage and to heat the low pressure stage of a machine by steam in the operating boiler or is produced in a special steam boiler. To contrast one To gain higher superheat, the procedure according to the,. He-. finding in that the steam, which serves as an indirect heating medium for reheating, dern high-tension heating steam for the operating boiler before its introduction in the latter is removed.

Die Zeichnung zeigt ein Ausführungsbeispiel Zur Erläuterung des Verfahrens in schematischer Darstellung.The drawing shows an exemplary embodiment to explain the method in a schematic representation.

a ist der Betriebsdampferzeuger, in welchem beispielsweise Betriebsdampf von 6o Atm. für die Hochdruckstufe h der Dampfmaschine erzeugt wird, b ist der Heizdampferzeuger,_in welchem Heizdampf von etwa roo bis 12o Atm. erzeugt wird, der nach dem Beispiel mittelbar in einem geschlossenen System umlaufend den Betriebsdampf erzeugt. Der Zwischenüberhitzer d enthält eine Heizschlange, 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 an den Zwischenüberhitzer.abgegeben hat, in den Heizdampferzeuger b zurück. Hierdurch kann der Zwischendampf zwischen der Hochdruckstufe h und der Niederdruckstufe n auf etwa 3ö0° und darüber überhitzt werden. e ist ein hinter dem Heizdampferzeuger b in den Rauchgaszug eingeschalteter Überhitzer für den Betriebsdampf, um diesen auf etwa 45o° zu überhitzen. Der Betriebskessel a kann in bekannter Weise von den Abgasen mit beheizt werden, oder er kann in bekannter Weise gegen diesen isoliert seien; 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.a is the operating steam generator in which, for example, operating steam from 6o Atm. is generated for the high pressure stage h of the steam engine, b is the heating steam generator, _in which heating steam from about roo to 12o atm. generated according to the example the operating steam is generated indirectly in a closed system. Of the Reheater d contains a heating coil, the feed line of which comes from the pipe of the heating steam generator b before the introduction of the heating steam into the. Operating boiler. a is branched off. A pump p conveys the steam, which gives off its heat to the reheater has to return to the heating steam generator b. This allows the intermediate steam between the high pressure stage h and the low pressure stage n are overheated to about 30 ° and above will. e is a switched on behind the heating steam generator b in the flue gas duct Superheater for the operating steam in order to superheat it to around 45o °. The operating boiler a can be heated by the exhaust gases in a known manner, or it can be used in a known manner Wisely be isolated from this; or in an equally known manner on from Heating steam generator be arranged in a separate location. The in the heating steam generator b generated steam can be saturated or superheated steam.
