Description

  

  Dampferzeuger mit     Speisewasservorwärmer.       Die Erfindung     betrifft    einen Dampferzeuger  mit     Speisewasservorwärmer    und besteht darin,  dass der durch eine offene Verbindung in den  Dampferzeuger mündende     Speisewasservor-          wärmer    auf der Eintrittsseite ausser an die       Speisewasserzuleitung    noch so an den Was  serraum des Kessels angeschlossen ist, dass  er selbsttätig aus dem Kessel Wasser zuge  führt erhält, wenn sein Inhalt infolge unter  brochener öder zeitweise ungenügender Speise  wasserzufuhr zum Teil in Dampfform über  gegangen ist, zum Zweck,

   das Speisewasser  unter Vermeidung der Gefahr einer uner  wünschten Dampfentwicklung im     Speisewas-          servorwärmer    und der damit verbundenen  Betriebsunsicherheiten auf     Sattdampftempe-          ratur    vorwärmen zu können. Die Eintritts  seite des     Speisewasservorwärmers    kann durch  ein     Rückschlagventil    an den Wasserraum des  Kessels angeschlossen sein, das sich selbst  tätig öffnet, sobald die Wassersäule im Vor  wärmer um einen gewissen Betrag unter die  vom Kessel her auf ihm lastende Wasser  säule herabsinkt.    Ein Ausführungsbeispiel des Erfindungs  gegenstandes ist auf der Zeichnung darge  stellt.

           ca    ist ein als     Steilrohrkessel    ausgebildeter  Dampferzeuger und b ein in üblicher Weise  an die     Speisewasserzuleitung    c und an den  Wasserraum der Obertrommel d angeschlos  sener     Speisewasservorwärmer.    Die Eintritts  seite des     Vorwärmers    ist ausser an die Speise  wasserzuleitung durch eine mit einem Rück  schlagorgane versehene Rückleitung     f    noch an  den Wasserraum der Obertrommel angeschlos  sen, und das     Rückschlagorgan    ist so eingestellt,  dass es sofort Kesselwasser in den     Vorwärmer     einströmen lässt,

   wenn in diesem durch eine  unerwünschte Dampfentwicklung die Wasser  säule leichter als diejenige im Kessel und  in der Leitung f geworden ist. Dadurch wird  erreicht, dass das Speisewasser im     Vorwärmer     bis auf     Sattdampftemperatur    vorgewärmt wer  den kann, ohne Gefahr laufen zu müssen,  dass im     Vorwärmer    zum Beispiel infolge un  genügender     Speisewasserzufuhr    oder infolge      Unterbruch derselben eine unerwünschte Ver  dampfung sich einstellt.



  Steam generator with feed water preheater. The invention relates to a steam generator with a feedwater preheater and consists in the fact that the feedwater preheater on the inlet side, which opens into the steam generator through an open connection, is connected to the water room of the boiler in addition to the feedwater supply line so that it automatically draws water from the boiler if its content has partly changed into steam form as a result of interrupted or temporarily insufficient food water supply, for the purpose,

   being able to preheat the feed water to saturated steam temperature while avoiding the risk of undesired steam development in the feed water preheater and the associated operational uncertainties. The inlet side of the feed water preheater can be connected to the water chamber of the boiler through a check valve, which opens itself actively as soon as the water column in the front of the warmer drops by a certain amount below the water column weighing down on it from the boiler. An embodiment of the subject invention is on the drawing provides Darge.

           ca is a steam generator designed as a steep tube boiler and b is a feed water preheater connected in the usual way to the feed water supply line c and to the water space of the upper drum d. The inlet side of the preheater is not only connected to the feed water supply line but also to the water space of the upper drum through a return line f provided with a non-return device, and the non-return device is set so that boiler water can immediately flow into the preheater,

   if in this the water column has become lighter than that in the boiler and in the line f due to an undesirable development of steam. This ensures that the feed water in the preheater can be preheated to saturated steam temperature without having to run the risk of undesired evaporation in the preheater, for example as a result of insufficient feed water supply or interruption of the same.
