Definitions
- the invention relates to a boiler for the combustion of liquid or gaseous fuels, consisting of an essentially cylindrical inner housing guiding the heating gases and the heat transfer medium, which is arranged in a heat-insulated manner in an outer housing on which the boiler control housing sits on the operator side.
- box-shaped housings also include a lot of free space, in that a certain heat build-up always occurs in the upper region, despite thermal insulation of the inner housing, which can have adverse effects on the boiler regulations which are generally placed directly on these housings and on the electronic components located therein.
- the invention is therefore based on the object of adapting boilers of the type mentioned better with regard to their outer housing to the shape of the inner housing, with the proviso that at the same time to provide a thermally exposed arrangement of the housing for the boiler control and ultimately also for an improved rigidity the relatively large side walls.
- This design of the outer housing results in improved stability of the side walls despite the use of thin sheet metal, the free space between the inner and outer housing is reduced to a minimum and the radiation surface of the inner housing, which is still effective upwards, is correspondingly reduced and also the surface of a cuboid housing, on which the housing for the boiler control sits, which is also better exposed to the air flowing from the outer housing, in contrast to the arrangement on a previously much larger surface of the housing, through which the attached controller housing is inevitably in a flow shadow.
- the width of the attached housing for the boiler control can correspond to the width of the surface of the housing, but a larger width is preferred in relation to the surface, since the housing for the boiler control thus projects beyond the surface of the outer housing on both sides and thus more strongly the inflowing air is exposed.
- the boiler is advantageously designed in such a way that the distance from the surface to the center of the inner housing is greater than the distance from the center of the inner housing to the base of the outer housing.
- an advantageous further development of the boiler consists in that an intermediate wall parallel to the surface is drawn in at least in the arrangement area of the boiler control housing in the upper part of the outer housing. Apart from this, such an intermediate wall, since this necessarily results in a channel, has the advantage that the cables and cable connections leading to the boiler control can be conveniently accommodated in such a channel.
- the outer casing according to the invention is an ideal solution, since this flue gas discharge pipe is the smallest external space stress can be arranged in the upper part of the outer housing, the side walls, because converging upwards, still offer enough space to still be able to accommodate the exhaust pipe with sufficient thermal insulation. In this case, of course, the insertion of a partition, as mentioned above, is absolutely necessary.
- the boiler consists of an essentially cylindrical inner housing 1 which guides the heating gases and the heat transfer medium and which is arranged in a heat-insulated manner in an outer housing 2 on which the housing 3 of the boiler control is seated on the operator side.
- the outer housing 2 is formed from upwardly converging side walls 6 which end in a housing surface 5 which is narrower than the base surface 4, of which partial regions 7 which are adjacent to the cylindrical inner housing 7 form cylindrical partial surfaces 8 which are arranged concentrically with the center M of the inner housing 1.
- the width B of the surface 5 of the outer housing 2 can either be the same or larger than the width B 1 of the housing 3 of the boiler control placed thereon.
- the embodiments according to FIGS. 3, 4 are preferred.

Abstract
Description
Die Erfindung betrifft einen Heizkessel für die Verbrennung flüssiger oder gasförmiger Brennstoffe, bestehend aus einem die Heizgase und den Wärmeträger führenden im wesentlichen zylindrischen Innengehäuse, das wärmeisoliert in einem Außengehäuse angeordnet ist, auf dem bedienungsseitig das Gehäuse der Kesselregelung sitzt.The invention relates to a boiler for the combustion of liquid or gaseous fuels, consisting of an essentially cylindrical inner housing guiding the heating gases and the heat transfer medium, which is arranged in a heat-insulated manner in an outer housing on which the boiler control housing sits on the operator side.
Derartige Heizkessel sind hinlänglich bekannt und in Benutzung, siehe "The steam and heating engineer" Bd 38, Nr. 453, August 1969, Seite 42; Abbildung 5.Abgesehen von Großkesseln, die in der Regel bezüglich ihrer isolierenden Außenummantelung im wesentlichen der Form des wasser- und gasführenden Innengehäuses entsprechen, ist es bezüglich der Außengehäuse von kleineren Heizkesseln üblich, diese Außengehäuse kastenförmig auszubilden, wobei diese Außengehäuse in der Regel aus Einzelblechen zusammengefügt werden. Für derartige Außenbleche ist man außerdem bemüht, das dafür verwendete Blech relativ dünn zu halten. Außerdem umfassen derartige kastenförmige Gehäuse auch viel Freiraum, indem sich im oberen Bereich trotz Wärmeisolation des Innengehäuses immer ein gewisser Wärmestau einstellt, der nachteilige Auswirkungen auf die in der Regel unmittelbar auf diese Gehäuse aufgesetzten Kesselregelungen und die darin befindlichen elektronischen Bauteile haben kann.Such boilers are well known and in use, see "The steam and heating engineer" Vol 38, No. 453, August 1969, page 42; Figure 5. Apart from large boilers, which generally correspond to the shape of the water and gas-carrying inner housing with regard to their insulating outer sheathing, it is customary with regard to the outer housing of smaller boilers to make these outer housings box-shaped, these outer housings generally made of individual sheets be put together. For such outer sheets, efforts are also made to keep the sheet used for this relatively thin. In addition, such box-shaped housings also include a lot of free space, in that a certain heat build-up always occurs in the upper region, despite thermal insulation of the inner housing, which can have adverse effects on the boiler regulations which are generally placed directly on these housings and on the electronic components located therein.
Der Erfindung liegt demgemäß die Aufgabe zugrunde, Heizkessel der eingangs genannten Art bezüglich ihres Außengehäuses besser an die Form des Innengehäuses anzupassen und zwar mit der Maßgabe, dabei gleichzeitig für eine thermisch exponiertere Anordnung des Gehäuses für die Kesselregelung zu sorgen und letztlich auch für eine verbesserte Steifigkeit der relativ großflächigen Seitenwände.The invention is therefore based on the object of adapting boilers of the type mentioned better with regard to their outer housing to the shape of the inner housing, with the proviso that at the same time to provide a thermally exposed arrangement of the housing for the boiler control and ultimately also for an improved rigidity the relatively large side walls.
Diese Aufgabe ist mit einem Heizkessel der eingangs genannten Art nach der Erfindung durch die im Kennzeichen des Patentanspruches 1 angeführten Merkmale gelöst. Vorteilhafte Weiterbildungen ergeben sich nach den Unteransprüchen.This object is achieved with a boiler of the type mentioned according to the invention by the features stated in the characterizing part of
Durch diese Ausbildung des Außengehäuses ergibt sich trotz Verwendung dünnen Bleches eine verbesserte Stabilität der Seitenwände, der Freiraum zwischen Innen- und Außengehäuse ist auf ein Minimum reduziert und ebenso ist die nach oben noch wirksame Abstrahlungsfläche des Innengehäuses entsprechend verkleinert und auch die Oberfläche eines quaderförmigen Gehäuses, auf der das Gehäuse für die Kesselregelung sitzt, das damit auch besser der am Außengehäuse aufströmender Luft ausgesetzt ist, und zwar im Gegensatz zur Anordnung auf einer bisher wesentlich größeren Oberfläche des Gehäuses, durch die das aufgesetzte Reglergehäuse zwangsläufig in einem Strömungsschatten liegt.This design of the outer housing results in improved stability of the side walls despite the use of thin sheet metal, the free space between the inner and outer housing is reduced to a minimum and the radiation surface of the inner housing, which is still effective upwards, is correspondingly reduced and also the surface of a cuboid housing, on which the housing for the boiler control sits, which is also better exposed to the air flowing from the outer housing, in contrast to the arrangement on a previously much larger surface of the housing, through which the attached controller housing is inevitably in a flow shadow.
Die Breite des aufgesetzten Gehäuses für die Kesselregelung kann dabei der Breite der Oberfläche des Gehäuses entsprechen, bevorzugt wird aber eine größere Breite in bezug auf die Oberfläche, da damit das Gehäuse für die Kesselregelung die Oberfläche des Außengehäuses beidseitig überragt und damit im stärkeren Maße aufströmender Luft ausgesetzt ist. Abgesehen davon und in Rücksicht auf die angestrebte thermisch exponiertere Anordnung des Gehäuses ist der Heizkessel in Weiterbildung vorteilhaft derart ausgebildet, daß die Distanz der Oberfläche zur Mitte des Innengehäuses größer ist als die Distanz der Mitte des Innengehäuses zur Grundfläche des Außengehäuses. Um auch dabei Wärmebelastungen der Kesselregelung weitestgehend auszuschließen, besteht eine vorteilhafte Weiterbildung des Heizkessels darin, daß mindestens im Anordnungsbereich des Gehäuses der Kesselregelung im Oberteil des Außengehäuses eine zur Oberfläche parallele Zwischenwand eingezogen ist. Abgesehen davon hat eine solche Zwischenwand, da sich dadurch zwangsläufig ein Kanal ergibt, den Vorteil, daß in einem solchen Kanal zweckmäßig die zur Kesselregelung führenden Kabel und Kabelanschlüsse bequem untergebracht werden können.The width of the attached housing for the boiler control can correspond to the width of the surface of the housing, but a larger width is preferred in relation to the surface, since the housing for the boiler control thus projects beyond the surface of the outer housing on both sides and thus more strongly the inflowing air is exposed. Apart from this and in view of the desired thermally exposed arrangement of the housing, the boiler is advantageously designed in such a way that the distance from the surface to the center of the inner housing is greater than the distance from the center of the inner housing to the base of the outer housing. In order to also largely rule out thermal loads on the boiler control, an advantageous further development of the boiler consists in that an intermediate wall parallel to the surface is drawn in at least in the arrangement area of the boiler control housing in the upper part of the outer housing. Apart from this, such an intermediate wall, since this necessarily results in a channel, has the advantage that the cables and cable connections leading to the boiler control can be conveniently accommodated in such a channel.
Für Heizkessel, bei denen das Innengehäuse mit einem dazu parallelen Rauchgasabführrohr versehen ist, das sich in der Regel auch oberhalb des Innengehäuses erstreckt und von einer Umlenkkammer zum Rauchgasabzugsstutzen am Kessel führt, stellt das erfindungsgemäße Außengehäuse geradezu eine ideale Lösung dar, da dieses Rauchgasabzugsrohr bei geringster äußerer Raumbeanspruchung im Oberteil des Außengehäuses angeordnet werden kann, dessen Seitenwände, da nach oben konvergierend, noch genügend Raum bieten, um das Abzugsrohr noch mit einer ausreichenden Wärmeisolation unterbringen zu können. Für diesen Fall ist natürlich der Einzug einer Zwischenwand, wie vorerwähnt, zwingend erforderlich.For boilers in which the inner casing is provided with a flue gas discharge pipe parallel to it, which usually also extends above the inner casing and leads from a deflection chamber to the flue gas discharge nozzle on the boiler, the outer casing according to the invention is an ideal solution, since this flue gas discharge pipe is the smallest external space stress can be arranged in the upper part of the outer housing, the side walls, because converging upwards, still offer enough space to still be able to accommodate the exhaust pipe with sufficient thermal insulation. In this case, of course, the insertion of a partition, as mentioned above, is absolutely necessary.
Der neuartige Heizkessel wird nachfolgend anhand der zeichnerischen Darstellung von Ausführungsbeispielen näher erläutert.The novel boiler is explained in more detail below with the aid of exemplary embodiments.

- FIG. 2 shows a longitudinal section through the boiler according to FIG. 1;
- 3, 4 other embodiments of the boiler in rear view corresponding to FIGS. 1 and
- Fig. 5 shows a longitudinal section through a special embodiment.
Der Heizkessel besteht aus einem die Heizgase und den Wärmeträger führenden, im wesentlichen zylindrischen Innengehäuse 1, das wärmeisoliert in einem Außengehäuse 2 angeordnet ist, auf dem bedienungsseitig das Gehäuse 3 der Kesselregelung sitzt.The boiler consists of an essentially cylindrical
Für einen derartigen Heizkessel und unabhängig davon, wie die Rauchgasabführung erfolgt, ist nun wesentlich, daß das Außengehäuse 2 aus nach oben konvergierenden, in einer gegenüber der Grundfläche 4 schmaleren Gehäuseoberfläche 5 endenden Seitenwänden 6 gebildet ist, von denen zum zylindrischen Innengehäuse benachbarte Teilbereiche 7 zylindrische Teilflächen 8 bilden, die konzentrisch zur Mitte M des Innengehäuses 1 angeordnet sind. Unter Verweis auf die Fig. 1, 3 und 4 kann die Breite B der Oberfläche 5 des Außengehäuses 2 entweder gleich oder auch größer bemessen sein wie die Breite B₁ des darauf aufgesetzten Gehäuses 3 der Kesselregelung. Bevorzugt werden dabei aus den genannten Gründen die Ausführungsformen nach den Fig. 3, 4.For such a boiler and regardless of how the flue gas is removed, it is now essential that the
Um das Gehäuse 3 der Kesselregelung thermisch so exponiert wir möglich in bezug auf das Innengehäuse anordnen zu können und um, bei gegebener entsprechender Konstruktion des Innengehäuses 1 (siehe Fig. 2), im Oberteil das Rauchgasabführrohr 11 mit entsprechender Isolierung unterbringen zu können, ist die Distanz D (siehe Fig. 3) der Oberfläche 5 zur Mitte M des Innengehäuses 1 größer als die Distanz D₁ der Mitte M des Innengehäuses 1 zur Grundfläche 4 des Gehäuses 2 bemessen. Die Ausführungsform gemäß Fig. 4 unterscheidet sich von der gemäß Fig. 3 lediglich nur dadurch, daß die Seitenwände 6 im unteren Bereich etwas abgeknickt sind und senkrecht auf die Grundfläche 4 stoßen, was vorteilhaft natürlich ebenfalls zur Aussteifung der Seitenwände 6 beiträgt.In order to be able to arrange the
Die Ausführungsform nach Fig. 5 stellt, abgesehen davon, daß hierbei, wie ersichtlich, die Rauchgasabführung nach hinten direkt erfolgt, insofern eine Besonderheit bezüglich der Gestaltung des Außengehäuses 2 dar, als hierbei das Außengehäuse 2 unterhalb der horizontalen Mittelebene 12 zylindrisch ausgebildet und an den Endbereichen 13 mit Sockeln 14 versehen ist, deren Außenflächen 15 sich in den Ebenen der sich oberhalb der Mittelebene 12 konvergierend erstreckenden Seitenwände 6 erstrecken. Da es sich bei Fig. 5 um eine Schnittdarstellung handelt, sind die mit 15 positionierten Flächen natürlich Innenansichten der Außenflächen 15. Diese Art der Gehäuseausbildung ist natürlich nicht an diese spezielle Kesselkonstruktion gebunden, sondern diese kann auch bei Kesselkonstruktionen gemäß Fig. 2 ohne weiteres zur Anwendung kommen.The embodiment according to FIG. 5, apart from the fact that, as can be seen, the flue gas discharge to the rear takes place directly, is a special feature with regard to the design of the
Die hier dargestellten und beschriebenen speziellen Ausführungsformen der Kessel, d.h., die gas- und wasserführenden Innengehäuse in den Fig. 2 und 5 sind nur als Beispiele zu verstehen, d.h., es kann sich bezüglich der eigentlichen Kessel bzw. Innengehäuse auch um andere, bspw. Gußgliederkessel handeln oder auch solche mit anders angeordneten Rauchgasabführungen.The special embodiments of the boiler shown and described here, that is, the gas and water-carrying inner housing in FIGS. 2 and 5 are only to be understood as examples, that is, with respect to the actual boiler or inner housing, there may also be others, for example. Acting cast iron boiler or also those with differently arranged flue gas outlets.
