Abstract

The condensing heating boiler consists of a water-bearing housing having feed and return connections, with combustion chamber and heating gas flues. The heating gas flues passing from the floor of a combustion chamber are arranged with descending gradients at each point of their course. The heating gas flues are constructed as heating gas flue pipes of stainless steel which open into a flue gas and condensate header chamber and which are helically twisted in a known manner as regards their walls, at least over a portion of their entire length. Furthermore, the water-bearing interior of the housing is subdivided into two parts connected by sheathing pipes which surround the heating gas flue pipes and are open at the bottom. The water-bearing housing (6) is provided on the outside, in the region of the lower inner space (6'), with an air duct casing (31) with air feed and return flow connections (32,33). <IMAGE>

Description

Kondensationsheizkessel Condensing boiler

(Zusatz zu P 32 38 603.6) Der Gegenstand der Hauptanmeldung (des Hauptanspruches) betrifft einen Kondensationsheizkessel gemäß Oberbegriff des Hauptanspruches. (Addition to P 32 38 603.6) The subject matter of the main application (des Main claim) relates to a condensation boiler according to the preamble of the main claim.

Um einen derartigen Kondensationsheizkessel insbesondere für den Fall relativ hoher Rücklauftemperaturen zu verbessern und damit den Wirkungsgrad zu erhöhen, worin die Aufgabe der vorliegenden Zusatzerfindung besteht, wird eine Weiterbildung des Heizungakesseis hinsichtlich seines wasserführenden Gehäuses im unteren Teil nach der Zusatzerfindung gemäß Kennzeichen des Hauptanspruches vorgesehen. Diesbezüglich vorteilhafte Weiterbildungen ergeben sich nach den Unteransprüchen.To such a condensation boiler in particular for the case improve relatively high return temperatures and thus increase efficiency, What is the task of the present additional invention is a further development of the heating equipment with regard to its water-bearing housing in the lower part provided according to the additional invention according to the characteristics of the main claim. Regarding this advantageous developments result from the subclaims.

Durch diese erfindungsgemäße Weiterbildung ist es möglich, den Kessel, der ja möglichst optimal bzgl. der Heiz- und Rauchgastemperatur bis zum Kondensatanfall heruntergekühlt werden soll, auch von außen zu kühlen, dabei die Kühlluft entsprechend zu erwärmen und diese ggf. in die zu heizenden Räume zu leiten, wodurch deren Temperaturnieveau schon einmal etwas angehoben werden kann. Selbstverständlich wäre es dabei möglich, diese erwärmte Luft ganz oder zum Teil auch dem Brenner zuzuführen.This further development according to the invention makes it possible to use the boiler, which is as optimal as possible with regard to the heating and flue gas temperature up to the occurrence of condensate should be cooled down, also to cool from the outside, the cooling air accordingly to heat and, if necessary, to lead them into the rooms to be heated, thereby reducing their temperature levels something can already be lifted. Of course it would be possible this heated air to supply all or part of the burner.

Durch diese Ausbildung, die relativ einfach zu verwirkchen ist, ist der weitaus aufwendigere Einbau von mit Kühl gas beaufschlagbaren Elementen im unteren Teil bzw.This training, which is relatively easy to implement, is the much more complex installation of elements that can be charged with cooling gas in the lower part Part or

im Kondensatsammeiraum vermeidbar, womit aber nicht ausgeschlossen sein soll,solche eingebauten Wärmetauschelemente zusätzlich vorzusehen.Avoidable in the condensate collection room, but this is not excluded should be to provide such built-in heat exchange elements in addition.

Der erfindungsgemäße Kondensationsheizkessel wird nachfolgend anhand der zeichnerischen Darstellung eines Ausführungabeispieles näher erläutert.The condensation boiler according to the invention is based on the following the graphic representation of an exemplary embodiment explained in more detail.

D'e dargestellte Anordnung der Brennkammer lo quer über dem unteren Teil 6' des wasserführenden Gehäuses 6' ist für den vorliegenden Sachverhalt nicht wesentlich.D'e shown arrangement of the combustion chamber lo across the lower Part 6 'of the water-bearing housing 6' is not for the present situation essential.

Wie aus der Darstellung des Ausführungsbeispieles erkennbar, ist auf dem Mantel 36 des unteren Gehäuseteiles ein Luftführungsmantel 31 mit Luftzufuhr- und Luftableitungsanschlüssen 32,33 angeordnet, der das ganze untere Gehäuse umschließt. Wegen des gewünschten Kühleffektes ist der Luftzufuhranschluß 32 natürlich unten angeordnet.As can be seen from the illustration of the exemplary embodiment, is on the jacket 36 of the lower housing part an air duct jacket 31 with air supply and arranged air discharge connections 32,33, which encloses the entire lower housing. Because of the desired cooling effect, the air supply connection 32 is of course at the bottom arranged.

Vorteilhaft ist dieser Luftführungsmantel 31 insgesamt als schraubenlinienförmig verlaufender Kanel 34 ausgebildet.This air guiding jacket 31 is advantageous overall as a helical line running channel 34 formed.

Um die durchgeleitete Luft, die mittels Saug- oder Druckgebläse (nicht dargestellt) gefördert wird, entweder im Mantel 31 oder im Kanal 34 optimal zu verteilen, sind im Mantel 31 oder im Kanal 34 entsprechend schraubenlinienförmig verlaufende Luftführungsleitstege 35 angeordnet, die zweckmäßig wärmeleitend mit dem Mantel 36 des unteren wasserführenden Gehäuseteiles verbunden sind. - L e e r s e i t e -In order to prevent the air being passed through, which is generated by means of suction or pressure fans (not shown) is promoted, to be optimally distributed either in the jacket 31 or in the channel 34, are in the jacket 31 or in the channel 34 correspondingly helically extending Air guide guide webs 35 arranged, which are expediently thermally conductive are connected to the jacket 36 of the lower water-bearing housing part. - L e r s e i t e -
