Description

Wärmeaustauschelement Zusatz zum Patent 867 861 Gemäß dem Patent 867 861 bestehen die Wärmeaustauschelemente aus zwei Schalen, die so aneinandergefügt sind, daß sie Einzelrohre umkleiden bzw. einen geschlossenen Durchlaß für das eine der beiden Wärmeaustauschmittel bilden und an ihrer äußeren Oberfläche mit Eintritts-, Düsen- und Austrittsrippen zum Zwecke einer Zerhackung und Umschichtung des Gasstromes versehen sind.Heat exchange element Addition to patent 867 861 According to patent 867 861, the heat exchange elements consist of two shells that are joined together in this way are that they cover individual pipes or a closed passage for one of the two heat exchange media and on their outer surface with inlet, Nozzle and outlet ribs for the purpose of chopping up and rearranging the gas flow are provided.

Enthält der Gasstrom viel Schmutz, wie dieses z. B. bei Verfeuerung von stark ballastreichen Brennstoffen der Fall ist, so müssen die Rippenabstände größere freie Querschnitte aufweisen. Mit Steigerung der Betriebsdrücke werden gleichzeitig kleinere Rohrdurchmesser für die Wärmeaustauscher verwendet, so daß die Rippen nach dem Hauptpatent aus Mangel an Unterbringungsfläche sowie vergrößerten Rippenabstand beim Ein- und Austritt zu kurzen Leitflächen und die Düsenrippen zu kleinen Wärmeaustauschansätzen zusammenschrumpfen, ganz oder zum Teil wegfallen bzw. beliebig geformt werden.If the gas stream contains a lot of dirt, such as this z. B. in the case of combustion is the case for fuels with a lot of fiber, the spacing between the ribs must be have larger free cross-sections. As the operating pressures increase, the same time smaller tube diameter used for the heat exchanger so that the fins after the main patent for lack of storage space and increased rib spacing at the inlet and outlet too short guide surfaces and the nozzle ribs too small heat exchange approaches shrink, completely or partially omitted or be shaped as desired.

Um ein Umschichten des Gasstromes bei dieser Ausführung zu sichern, muß derselbe erfindungsgemäß mit solcher Geschwindigkeit an die zusammengeschrumpften Wärmeaustauschansätze bzw. -rippen stoßen, daß dabei eine den Gasstrom umschichtende Turbulenz entsteht.In order to ensure that the gas flow is rearranged in this version, must the same according to the invention at such a speed to the shriveled Heat exchange approaches or fins encounter that in the process a shifting of the gas flow Turbulence arises.

Bedingt durch die Turbulenz können unter Umständen die Durchgangswiderstände groß werden. Eine Abhilfe kann durch Anwendung von stromlinienförmig gestalteten Leitflächenrippen bekannter Art erfolgen:Due to the turbulence, the volume resistances can under certain circumstances grow up. A remedy can be by applying streamlined ones Control surface ribs of a known type are made:
