Abstract

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Abtransport von Gasblasen aus einer doppelwandigen wassergekühlten Brennkammer (10) eines Wassererhitzers bei dem während des Betriebs in der Brennkammer (10) eine Wasserströmung erzeugt wird.The invention relates to a method and a device for the removal of gas bubbles from a double wall water-cooled combustion chamber (10) of a water heater one during operation in the combustion chamber (10) Water flow is generated.

Es wird vorgeschlagen, daß in einem vorgegebenen Bereich der doppelwandigen Brennkammer (10) die Strömungsgeschwindigkeit des Wassers in einem Strömungskanal (46d) durch eine Engstelle (64) erhöht wird.
