Abstract

The boiler consists of a housing which conducts water and has flow and return connections, with combustion chamber and heating gas flues. The heating gas flues extending from the floor of a combustion chamber are provided with descending gradients at each point of their course and open into a condensate collection chamber. A heat exchanger (31) with feed and drain connections (33) for the liquid or gaseous secondary medium is arranged in the condensate chamber (2). <IMAGE>

Kondensationsheizkessel Condensing boiler

======================= (Zusatz zu P 32 38 603.6) Der Gegenstand der Hauptanmeldung (des Hauptanspruches) betrifft einen Kondensationaheizkessel gemäß Oberbegriff des Hauptanspruches. ======================== (Addition to P 32 38 603.6) The subject The main application (the 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 weiter zu erhhen, worin die Aufgabe der vorliegenden Zusatzerfindung besteht, wird eine Weiterbildung des Heizungskessels hinsichtlich des notwendig zum Kessel gehörenden Kondensatsammelraumes nach der Zusatzerfindung gemäß Kennzeichen des Hauptanspruches worgesehen. Dieshezüglich vorteilhafte Weiterbildungen ergeben sich nach den Unteransprüchen.To such a condensation boiler in particular for the case Improve relatively high return temperatures and thus further improve efficiency to increase, in which the object of the present additional invention consists, becomes a Further development of the heating boiler with regard to what is necessary for the boiler Condensate collecting space according to the additional invention according to the characteristics of the main claim what saw. Advantageous developments in this regard result from the subclaims.

Der im Kondensataammelraum angeordnete Wärmetauscher ist insbesondere für die Durchleitung eines gasförmigen Mediums als Sekundarmedium bestimmt, womit aber andere Wärmeträgermdien (bspw. Wasser) nicht ausgeschlossen sein sollen. Vorzugsweise kommt Luft in Frage, die nach Passage des WSrmetauschers und entsprechender WSrmeaufnahme hspu. in geeigneter Weise in zu beheizende Räume geleitet werden kann, wofür das Ganze mit einem geeigneten Ssug- oder Druckgebläse, bzw.The heat exchanger arranged in the condensate collection chamber is in particular intended for the passage of a gaseous medium as a secondary medium, with which but other heat transfer media (e.g. water) should not be excluded. Preferably air comes into question after passing through the heat exchanger and corresponding heat absorption hspu. in an appropriate manner into rooms to be heated can, for which the whole thing with a suitable suction or pressure fan, resp.

bei nicht gasförmigen Medien mit einer Zirkulationspumpe versehen wird. Das Ganze kann aber auch zur Brauchwsssererwärmung bzw. Srauchwasservorwärmung dienen.Equipped with a circulation pump for non-gaseous media will. The whole thing can also be used for domestic hot water heating or domestic hot water preheating to serve.

Der Kondenaationsheizkessel gemäß vorliegender Zusatzerfindung wird nachfolgend anhand der zeichnerischen Darstellung eines AusfUhrungsbeispieles naher erläutert, Es zeigt schematisch Fig. 1 den Kondensationsheizkessel in Seitenansicht mit Schnitt durch die Kondensataammelkammer und Fig. 2 eine Draufsicht auf die nach oben offen dargestellte Kondensatsammelkammer.The condensation boiler according to the present additional invention is in the following on the basis of the graphic representation of an exemplary embodiment It shows schematically Fig. 1 the condensation boiler in side view with a section through the condensate collection chamber and FIG. 2 is a plan view of the after condensate collecting chamber shown open at the top.

Wie aus den Fig. 1,2 erkennbar, ist in der Kandensatsammelkammer 2 der Wärmetauscher 31 in Form eines zweilagig spiralförmig verlaufenden Rohres 36 mit Zu- und Ablaufanschlüssen 32,33 angeordnet, wobei das Rohr 31 schraubenllnienfGrmig verwundene Wunde 36 aufweist, die dem Wärmetausch besonders fUrderlich sind.As can be seen from FIGS. 1, 2, there is 2 the heat exchanger 31 in the form of a two-layer spiral tube 36 with inflow and outflow connections 32, 33, the pipe 31 having a helical shape has twisted wound 36, which are particularly conducive to heat exchange.

Sämtliche mit dem Kondensat in Berührung kommende Teile sind selbstveretHndlich aue kondensatfeatem Material gefertigt.All parts that come into contact with the condensate are self-evident Made of condensate breath material.

ber Kondensatsammelraum 2 ist in Bezug auf den Rauchgasabzug 34 durch eine Blende 35 abgeschirmt, so daß die aus den Heizgaszugrohren 4 austretenden Rauchgase bei gefülltem Kondensatsammelraum 2 nur durch das Kondensat durch zum Rauchgasabzug 34 gelangen kennen, was einen ausreichenden Druck'der Rauchgase voraussetzt.About the condensate collecting space 2 is with respect to the flue gas vent 34 through a screen 35 is shielded so that the smoke gases emerging from the heating gas supply pipes 4 when the condensate collecting chamber 2 is full, only through the condensate to the flue gas outlet 34 get to know what a sufficient pressure of the flue gases requires.

Wie dargestellt, ist die Blende 35 als Ringblende 35 ausgebildet, wobei deren Unterkante 36 in Höhe Unterrand 37 des Kondensatüberlaufanschlusses 18 angeordnet ist, der somit den möglichen Höchststand des Kondensates in der Kondensatsammelkammer 2 bestimmt.As shown, the aperture 35 is designed as an annular aperture 35, its lower edge 36 at the level of the lower edge 37 of the condensate overflow connection 18 is arranged, which thus the possible maximum level of condensate in the condensate collection chamber 2 determined.

Der Kondensatüberlaufanschluß 18 muß nicht zwingend, wie dargestellt, auf Höhe Unterrand 36 der Blende 35 angeordnet werden, sondern es ist auch möglich, diesen Anschluß 18 unmittelbar Uber dem Boden 16 oder am Boden selbst anzuordnen, sofern dieser Anschluß 18 dann auBerhalb der Kondensatsammelkammer 2 mit einer geeigneten und vorzugsweise biegsamen Leitung versehen ist (nicht dargestellt), mit der je nach Niveaueinstellung sich sammelndes Kondensat bis auf Höhe Unterrand 36 der Blende 35 angestaut werden kann, d.h., bei dieser Ausfflhrungsform kann der Kegel entweder mit ungestauter bzw. gestaute Kondensatabfuhr gefahren werden.The condensate overflow connection 18 does not necessarily have to be, as shown, be arranged at the level of the lower edge 36 of the panel 35, but it is also possible to arrange this connection 18 directly above the floor 16 or on the floor itself, provided that this connection 18 is then outside the condensate collection chamber 2 with a suitable one and preferably flexible conduit is provided (not shown) with the ever After the level has been set, the condensate collects up to the level of the lower edge 36 of the cover 35 can be backed up, i.e. in this embodiment the cone can either be operated with non-backed or backed-up condensate drainage.
