Abstract

The heating boiler has an intermediate heating surface crossways to the combustion chamber axis for screening of subsequently connected exchanger units against excessive energy input. This surface is formed by several pipes through which water flows and which have a triangular cross-section. The pipes can also have arbitrary cross-sections or combined triangular and other forms. The flue gas is produced by combustion in a horizontal cylindrical combustion chamber (1), flows over the intermediate heating surface (2) to the calorific value heat exchanger (3) beneath and leaves the boiler through the flue gas outlet (4). The cold return flow water (5) flows through the heat exchanger to the boiler outlet (6) above the combustion chamber.

Description

Die Erfindung betrifft einen Abgaswärmetauschereinrichtung, insbesondere einen Brennwertheiz­ kessel, der zur Erwärmung von Heizungswasser eingesetzt werden kann. Die Beheizung erfolgt in der Regel mit einem öl- oder gasbetriebenen Gebläsebrenner.The invention relates to an exhaust gas heat exchanger device, in particular a condensing heater boiler that can be used to heat heating water. The heating takes place in usually with an oil or gas powered forced draft burner.

Wie aus Patentanmeldung 197 11 353.2 bekannt, wird das Rauchgas durch Verbrennung in einem waagerechten zylindrischen Brennraum erzeugt (Pos. 1, Fig. 1), strömt über die Zwischenheizflä­ che (Pos. 2, Fig. 1) zum darunterliegenden Brennwertwärmetauscher (Pos. 3, Fig. 1) und verläßt den Kessel durch den Rauchgasaustritt (Pos. 4, Fig. 1).As is known from patent application 197 11 353.2, the flue gas is generated by combustion in a horizontal cylindrical combustion chamber (item 1 , Fig. 1), flows over the Zwischenheizflä surface (item 2 , Fig. 1) to the underlying condensing heat exchanger (item 3 , Fig. 1) and leaves the boiler through the flue gas outlet (item 4 , Fig. 1).

Das kalte Rücklaufwasser (Pos. 5, Fig. 1) fließt durch den Brennwertwärmetauscher zum Kessel­ austritt (Pos. 6, Fig. 1) oberhalb der Brennkammer.The cold return water (item 5 , Fig. 1) flows through the condensing heat exchanger to the boiler outlet (item 6 , Fig. 1) above the combustion chamber.

Zielsetzung war es, die hocheffiziente Brennwerttauscherfläche aus 6-Eck Rohren (3) nicht der Strahlungsenergie des Brenners auszusetzen um örtliche Überhitzungen zu vermeiden, sowie einen kompakten Kessel zu konstruieren.The aim was not to expose the highly efficient condensing heat exchanger surface made of hexagonal tubes ( 3 ) to the radiant energy of the burner in order to avoid local overheating, and to construct a compact boiler.

Die Baukosten sollten niedrig und die Integration einfach zu erreichen sein.Construction costs should be low and integration should be easy to achieve.

Die Aufgabe wird gemäß der Erfindung durch eine Zwischenheitsfläche gelöst, die kesselintern entgegen der Patentanmeldung 197 11 353.2 durch quer zur Brennkammerachse angeordnete Heizflächen aufgebaut ist.The object is achieved according to the invention by an intermediate surface, the inside of the boiler contrary to the patent application 197 11 353.2 arranged transversely to the combustion chamber axis Heating surfaces is built.

Durch Plazierung und Formgebung der Heizflächen kann keine Strahlungsenergie auf die Brennwerttauscherfläche treffen. By placing and shaping the heating surfaces, no radiant energy can be applied to the Hit the condensing surface.  

In der bisherigen Bauform sind immer getrennte Systeme bzw. mehrere Rauchgaszüge erforder­ lich gewesen. Durch diese neue, kompakte Bauform ist eine günstigere und kompaktere Aus­ führung möglich.In the previous design, separate systems or several flue gas flues were always required been. This new, compact design makes it cheaper and more compact leadership possible.

Die Erfindung wird nachstehend anhand der in den Zeichnungen dargestellten Ausführungs­ beispielen erläutert.The invention is described below with reference to the embodiment shown in the drawings examples explained.
