Abstract
Der Flammenumlenktopf (2) im Brennraum (1) eines Heizungskessels besitzt eine zur Senkrechten geneigte, hintere Begrenzungswand (6).The flame deflector (2) in the combustion chamber (1) of a heating boiler has a rear boundary wall (6) which is inclined to the vertical.
Description
Hierzu 1 Blatt Zeichnungen1 sheet of drawings
Die Erfindung bezieht sich auf einen Flammenumlenktopf nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a flame deflector according to the preamble of claim 1.
Ein Flammenumlenktopf dieser Art ist nach der DE-PS 29 10 409 bekannt. Dort werden die Brennerflamme und die Heizgase zum Brennerende zurückgelenkt. Sie strömen dann durch einen ringzylindrischen Heizgaszug mit Längsrippen zwischen Brennkammerwand und Umlenktopf zum Abgassammler.A flame deflector of this type is known from DE-PS 29 10 409. There will be the burner flame and the heating gases are directed back to the end of the burner. They then flow through a ring-cylindrical hot gas flue with longitudinal ribs between the combustion chamber wall and the deflector to the exhaust manifold.
Bei modernen Niedertemperaturkesseln kann sich bei bestimmten Betriebsphasen im hinteren Bereich des ringzylindrischen Heizgaszuges Kondensat bilden. Dieses scheidet sich in den kühleren unteren Zonen verstärkt aus. Ferner kann sich das Kondensat aus den höheren Zonen des Heizgaszuges im unteren Bereich sammeln.With modern low-temperature boilers, the ring-cylindrical heating gas flue form condensate. This separates itself more strongly in the cooler lower zones the end. Furthermore, the condensate from the higher zones of the hot gas flue can be in the lower area collect.
Es soll eine verstärkte Ausscheidung von Kondensat im unteren Bereich des Heizgaszuges verhindert und gleichzeitig eventuell sich ansammelndes Kondensat so schnell wie möglich verdampft werden.It is intended to prevent increased excretion of condensate in the lower area of the hot gas flue and at the same time, any condensate that may have accumulated is evaporated as quickly as possible.
Die Lösung der Aufgabe erfolgt gemäß der Erfindung durch die im Kennzeichen des Patentanspruchs 1 genannten Merkmale.The object is achieved according to the invention by those mentioned in the characterizing part of claim 1 Characteristics.
Die zur Senkrechten geneigte, hintere Begrenzungswand sorgt für eine erhöhte Wärmestrahlung zum unteren Brennkammerbereich hin. Auch die Strömungsintensität ist im unteren Bereich des Heizgaszuges, etwas größer, und zwar ohne wesentliche Veränderung der Abgastemperatur. Es erfolgt eine stärkere Aufheizung des gefährdeten unteren Bereichs des Heizgaszuges, was zu einer verminderten Ausscheidung von Kondensat speziell in diesem Bereich und zu einem schnelleren Verdampfen von vorhandenem Kondensat führt.The rear boundary wall, which is inclined to the vertical, ensures increased heat radiation to the lower one Combustion chamber area. The flow intensity is also somewhat in the lower area of the hot gas flue larger, without any significant change in the exhaust gas temperature. There is stronger heating of the endangered lower area of the hot gas flue, which leads to a reduced excretion of Condensate especially in this area and for faster evaporation of existing condensate leads.
Eine geneigte hintere Begrenzungswand eines Brennraumes ist aus der DE-AS 12 80 523 wohl als vorbekannt zu entnehmen. Es handelte sich dabei aber um einen anderen Kesselaufbau und um eine andere Aufgabenstellung. Die Entstehung großer Dampfblasen an der Wasserseite der Begrenzungswand sollte verhindert werden. Eine Einwirkung im Sinne einer Kondensatverhinderung und -verdampfung war nicht beabsichtigt.An inclined rear boundary wall of a combustion chamber is well known from DE-AS 12 80 523 as previously refer to. However, it was a different boiler structure and a different task. The formation of large steam bubbles on the water side of the boundary wall should be prevented will. An effect in the sense of preventing and evaporation of condensate was not intended.
Eine auf der Höhe der Brennerflamme liegende, ebenfalls etwas geneigte Ausbuchtung ermöglicht eine gewisse Lenkung des Flammenkerns.A slightly inclined bulge at the level of the burner flame enables one some steering of the flame kernel.
Die geneigte hin :ere Begrenzungswand kann mit dem FlammenumkehrtoDf aus einem Stück bestehen. Beson-The inclined towards: ere boundary wall can consist of one piece with the flame reversal door. Special
