Abstract
Die Erfindung betrifft ein Gas-Heizgerät für Wassererhitzer mit einem Gebläse, das die Verbrennungsluft durch eine Vormischkammer zu einem Vormischbrenner fördert, ferner mit einem stromab des Vormischbrenners angeordneten, eine Brennkammer umschließenden Verbrennungsschacht, der von einem strömenden Fluid gekühlt und ausgangsseitig von einem Wärmeübertrager abgeschlossen ist, und mit einer Einrichtung zum Abführen der aus dem Wärmeübertrager austretenden Abgase.The invention relates to a gas heater for water heaters with a fan that blows the combustion air through a Promotes premixing chamber to a premix burner, also with a downstream of the premix burner, one Combustion chamber enclosing combustion shaft, which by a flowing fluid cooled and the output side of one Heat exchanger is complete, and with a facility for removing those exiting the heat exchanger Exhaust gases.
Es wird vorgeschlagen, daß der Verbrennungsschacht (16) luftgekühlt ist und zur Förderung des Kühlluftstromes das Gebläse (10, 50) für die Verbrennungsluft dient. Das hat den Vorteil, daß bei Heizgeräten mit einem Vormischbrenner ohne zusätzliche Anordnung eines Gebläses für die Kühlluftförderung eine gute Kühlwirkung und ein hoher Wasserwirkungsgrad erreichbar ist. It is proposed that the combustion shaft (16) is air-cooled and the fan (10, 50) for the combustion air is used to promote the cooling air flow. This has the advantage that a good cooling effect and a high water efficiency can be achieved in heaters with a premix burner without additional arrangement of a blower for the conveying of cooling air.
