Abstract

The boiler assembly, for use with an oil or gas burner, has a boiler zone (4) formed by at least two dividing walls (17,18) to give at least three chambers. The dividing walls flank the combustion chamber, with passages (19-22) at the upper and lower sections, so that the heated medium can rise from the combustion chamber through the center chamber. It flows through the upper parts of the side chambers, and the cooled medium is led back into the center chamber.

Description

Die vorliegende Erfindung bezieht sich auf eine Heizkesselanlage gemäss Oberbegriff von Patentanspruch 1. Solche Heizkesselanlagen, beispielsweise für Oel- oder Gasbrenner, sind im allgemeinen bekannt und im Handel erhältlich. Einer der Faktoren, der den Wirkungsgrad einer Heizkesselanlage bestimmt, ist der Wärmeübergang von den Heizgasen, bzw. von der Brennkammer auf das zu erwärmende Heizwasser.The present invention relates to a Boiler system according to the preamble of claim 1. Such boiler systems, for example for oil or Gas burners are well known and commercially available available. One of the factors that affect the efficiency of a Boiler system determines the heat transfer from the Heating gases, or from the combustion chamber to what is to be heated Heating water.

Es ist davon ausgehend Aufgabe der vorliegenden Erfindung, eine Heizkesselanlage anzugeben, die einerseits einen besseren Wirkungsgrad dadurch erzielt, dass der Wärmeaustausch zwischen den Heizgasen und der Brennkammer und dem Heizmedium verbessert wird, ohne für die dadurch notwendige Wasserzirkulation eine elektrische Pumpe verwenden zu müssen. Diese Aufgabe wird mit einer Heizkesselanlage gemäss Patentanspruch 1 gelöst.Based on this, it is an object of the present invention to specify a boiler system that on the one hand achieved better efficiency by the fact that Heat exchange between the heating gases and the combustion chamber and the heating medium is improved without this necessary water circulation an electric pump to have to use. This task is done with a Boiler system according to claim 1 solved.

Die Erfindung wird im Einzelnen anhand einer Zeichnung eines Ausführungsbeispiels näher erläutert.

The invention is explained in more detail with reference to a drawing of an embodiment.
Fig. 1
shows in longitudinal section a boiler system according to the invention and
Fig. 2
shows the system of Fig. 1 in a view from the front.

Der Schnitt von Fig. 1 zeigt einen Heizkessel 1 mit einer Brennkammer 2 und einem Brenner 3, beispielsweise ein sogenannter Blaubrenner. Im Innenraum des Heizkessels, im Kesselraum 4, befindet sich die Wärmetauschereinrichtung 5 mit einem Heizgas-Röhrensystem 6, wobei die Laufrichtung der Heizgase mittels den Pfeilen 7 angegeben ist. Die Heizgasrohre werden von einem Heizmedium 8, beispielsweise Wasser, umspült.The section of Fig. 1 shows a boiler 1 with a Combustion chamber 2 and a burner 3, for example a so-called blue burner. Inside the boiler, in the Boiler room 4, there is the heat exchanger device 5 with a heating gas tube system 6, the running direction of the Heating gases is indicated by the arrows 7. The Heating gas pipes are from a heating medium 8, for example Water, washed around.

Das Heizmedium 8 wird über die Heizgruppe 9 zu- bzw. abgeführt, wie dies aus den Pfeilen 10 und 11 für den Vorlauf, bzw. Rücklauf des Heizkreises in Fig. 2 hervorgeht.The heating medium 8 is supplied or heated via the heating group 9 dissipated as this from arrows 10 and 11 for the Flow or return of the heating circuit in Fig. 2 emerges.

Die Heizgase gelangen über einen Kunststoffwärmetauscher 12, wo sie die hineinströmende Brennerluft 13 erwärmen, über ein Abgasgebläse 15 in die Abgasleitung 14, während die vorgewärmte Brennerluft zum Brenner 3 gelangt. Dadurch werden die Heizgase über den Taupunkt abgekühlt und optimal genutzt. Der Brenner ist ausserdem noch von einer Schallschutzhaube 16 umgeben.The heating gases pass through a plastic heat exchanger 12, where they heat the burner air 13 flowing in via a Exhaust fan 15 in the exhaust pipe 14 while the preheated burner air reaches burner 3. Thereby the heating gases are cooled down above the dew point and optimal used. The burner is also from one Soundproof hood 16 surrounded.

Wichtige Elemente der Erfindung sind in Fig.2 dargestellt. Wie daraus hervorgeht, ist der Kesselraum 4 mittels zweier Trennwände 17 und 18 in drei Kammern unterteilt, in die mittlere Kammer M, und in die beiden Seitenkammern S1 und S2. Die Bleche 17 und 18 führen um die Brennkammer herum und sind oben mit Schlitzen 19, bzw. 20 und unten mit Schlitzen 21, bzw. 22 versehen, wodurch bei Erhitzung eine Wasserzirkulation in Gang gesetzt wird, die durch die Pfeile 23 und 24 oben, bzw. 25 und 26 unten angedeutet ist. Im unteren Bereich können weitere Schlitze 27, bzw. 28 in den Trennwänden angeordnet sein. Des Weiteren ist in Fig. 2 die Heizgaszirkulation mittels den Pfeilen 7 dargestellt.Important elements of the invention are shown in Fig.2. As can be seen from this, the boiler room 4 is by means of two Partitions 17 and 18 divided into three chambers in the middle chamber M, and in the two side chambers S1 and S2. The sheets 17 and 18 lead around the combustion chamber and are at the top with slots 19 or 20 and below with slots 21, or 22 provided, which when heated a Water circulation is started by the arrows 23 and 24 above, or 25 and 26 is indicated below. in the further slots 27, or 28 in the lower area Partitions can be arranged. Furthermore, in FIG Heating gas circulation represented by the arrows 7.

In vorliegendem Beispiel ist die Brennkammer mit radialen Rippen 29 versehen, um eine grossflächige Wärmeübergangszone zu schaffen. Eine eingeschobene Feuerbüchse 31 zwingt die Heizgase nach der Umlenkung im hinteren Teil der Brennkammer durch eine Wärmeübergangszone. In the present example, the combustion chamber is radial Ribs 29 provided to a large-area heat transfer zone to accomplish. An inserted firebox 31 forces the Heating gases after the deflection in the rear part of the combustion chamber through a heat transfer zone.

Wie bereits angedeutet, wird in der mittleren Kammer M das erwärmte Wasser hochgetrieben und strömt dann durch die Schlitze 19 und 20 nach aussen in die Seitenkammern S1 und S2 und dort nach unten, wobei es dann über die Schlitze 21 und 22 wieder in die innere Kammer gelangt. Dadurch entsteht eine Wasserzirkulation ohne Pumpe, wobei die mittlere Kammer M wie ein Kamin wirkt, um das Heizmedium hochzutreiben.As already indicated, in the middle chamber M that warmed up water and then flows through the Slots 19 and 20 outwards into the side chambers S1 and S2 and down there, where it then goes through the slots 21 and 22 gets back into the inner chamber. This creates a water circulation without a pump, the middle chamber M acts like a chimney to drive up the heating medium.

Durch diese Heizmediumzirkulation wird ein intensiverer Wärmeaustausch zwischen der Brennkammer und den Heizgasrohren einerseits und dem Heizmedium, dem Wasser, andererseits erzielt, wobei nicht nur die Heizmedium-Pumpe entfällt sondern auch die Konstruktion insgesamt durch das Einführen von Blechen mit Öffnungen einfach wird.This heating medium circulation makes it more intensive Heat exchange between the combustion chamber and the Heating gas pipes on the one hand and the heating medium, the water, achieved on the other hand, not only the heating medium pump but also eliminates the overall construction through the Introducing sheet metal with openings becomes easy.

Ausgehend von der vorhergehenden Beschreibung ist festzustellen, dass die Erfindung nicht auf die spezielle Ausgestaltung der Brennkammer beschränkt ist und auch nicht auf die Wahl des Brenners, während die genaue Ausgestaltung der Trennwände sich nach dem Äusseren der Brennkammer richten kann, wobei die Hauptsache ist, dass eine mittlere Brennkammer entsteht, in der das Heizmedium kaminartig hochgetrieben wird.Starting from the previous description is state that the invention is not specific Design of the combustion chamber is limited and not on the choice of burner, while the exact design the partitions are located on the outside of the combustion chamber can judge, the main thing is that a medium Combustion chamber is created in which the heating medium is chimney-like is driven up.

Anstatt Schlitze können auch anders geartete Durchgänge und Öffnungen verwendet werden. Obwohl die Unterteilung des Kesselraums in drei Kammern für die meisten Anlagen vorteilhaft ist, kann auch eine andere Unterteilung, z.B. in mehr Kammern, zweckmässig sein.Instead of slots, other types of passages and Openings are used. Although the subdivision of the Boiler room in three chambers for most systems another subdivision, e.g. in more chambers, be practical.
