Abstract

The hot water boiler for liquid or gaseous fuels has a cylindrical heat transfer medium casing (26) which has a combustion chamber (2) to which is connected a waste heat zone (3). Swirl discs (5) with intermediate spaces (6) are installed one behind the other in the waste heat zone, and ribs (7) are rigidly connected to the heat transfer medium side of the combustion chamber and waste heat zone to promote heat transfer. The first swirl discs in the flow direction of the waste gases may have an insulating layer.

Description

Die Erfindung bezieht sich auf einen Heizkessel gemäß den Ausführungsbegriff nach den Ansprüchen 1 bis 4.The invention relates to a boiler according to the embodiment according to claims 1 to 4.

Ein Heizkessel mit glatten Heizflächen ist zum Beispiel aus der DE 2028253 bekannt. Bei diesem bekannten Heizkessel ist der ringförmige Abgaszug von der glatten Innenseite eines wassergekühlten Zylinders durch einen zur Brennkammer hin verschlossenen und nach unten zum Abgasabzug hin offenen Einbauzylinder ausgefüllt.A boiler with smooth heating surfaces is known for example from DE 2028253. In this known boiler, the annular flue gas is from the smooth inside of a water-cooled cylinder through one to the combustion chamber installation cylinder closed towards the bottom and open towards the exhaust gas outlet filled.

Die Einbuchtungen am Einbauzylinder lassen aber keine Gasmischung zu. Das Gas wird bei dem erwähnten Einbauzylinder in einem kleinen Querschnitt schnell zum nächsten Ringspalt geführt. Dies ist dort auch gewollt um Ablagerungen auf den Rippen zu vermeiden. Das Gewicht eines solchen Einbauzylinders erschwert die immer notwendige Reinigung erheblich. Zudem führt der nicht gekühlte Einbauzylinder mit großer Wärmekapazität beim Stillstand des Brenners zu ungünstigen Rückstrahlungen und Stillstandsverlusten.However, the indentations on the built-in cylinder do not allow a gas mixture. The With the installation cylinder mentioned, gas becomes quick in a small cross section led to the next annular gap. This is also wanted there for deposits to avoid the ribs. The weight of such an installation cylinder complicates the always necessary cleaning considerably. In addition, the non-cooled installation cylinder leads with large heat capacity when the burner is at a standstill Reflections and loss of standstill.

Erfindung:Invention:

Die Erfindung hat sich zur Aufgabe gemacht, durch eine kostengünstige Heizkesselgestaltung einerseits und andererseits eine möglichst gute Ausnutzung der von den Brennstoffen kommenden Wärme, bei weitgehenster Schonung der Umwelt zu erreichen. Die Lösung dieser Aufgabe wird in den Ansprüchen 1 bis 4 beschrieben.The invention has set itself the task of an inexpensive boiler design on the one hand and on the other hand the best possible use of the heat coming from the fuels, with the greatest possible protection of the environment to reach. The solution to this problem is described in claims 1 to 4.

Die Wirbelscheiben bewirken, daß sich die Abgase vor und in den Zwischenräumen, der Wirbelscheiben, ungehindert verteilen und mischen können, um danach über einen geringen Widerstand zum nächsten Zwischenraum zu strömen. Während der verhältnismäßig langen Aufenthaltszeit in den Zwischenräumen geben die Abgase dabei ihre Wärme an den Wärmeträger ab. Dieser Vorgang wird durch die große Oberfläche der Rippen auf der Wärmeträgerseite der Brennkammer-und der Abhitzezonenwand begünstigt. Es findet dadurch ein besonders günstiger Wärmeübergang vom warmen Abgas zum Wärmeträger statt. Die Wirbelscheiben werden von geeigneten Vorrichtungen, vorzugsweise mittig und mit geringem Raumverlust, in Strömungsrichtung günstigster Position gehalten.The vortex disks cause the exhaust gases in front of and in the spaces, of the vertebral discs, freely distribute and mix to afterwards to flow through a slight resistance to the next gap. While the relatively long time in the interstices the exhaust gases transfer their heat to the heat transfer medium. This is done by the large surface of the fins on the heat transfer side of the combustion chamber and the heat zone wall favors. This makes it a particularly affordable one Heat transfer from the warm exhaust gas to the heat transfer medium instead. The vertebral discs are of suitable devices, preferably in the middle and with little Loss of space, held in the most favorable position in the direction of flow.

Zu Wartungs- und Reinigungszwecken können die Wirbelscheiben, besonders wenn sie in Pakete zusammengefaßt werden, leicht entnommen und danach wie-der in richtiger Position eingesetzt werden. Die Wärmeübertragerflächen sind bei entnommenen Wirbelscheiben, auf der Innenseite der Brennkammerwand und der Abhitzezonenwand gut einsehbar und können so leicht geprüft werden und sind für eine Reinigung gut zugänglich. Alle möglicherweise vom Abgaskondensat berührten Teile sind beschichtet und aus Normalstahl gefertigt, um giftige Schwermetallaustragungen zu vermeiden.For maintenance and cleaning purposes, the vertebral disks, especially if they are combined in packages, easily removed and then again be used in the correct position. The heat exchanger surfaces are at removed vortex discs, on the inside of the combustion chamber wall and the The heat zone wall is clearly visible and can be easily checked easily accessible for cleaning. Anything touched by the exhaust gas condensate Parts are coated and made of mild steel to remove toxic heavy metals to avoid.

Fig. 1 zeigt ein Ausführungsbeispiel eines Heizkessels in vertikaler Bauweise. Der Brenner (1) brennt dabei senkrecht in die Brennkammer (2). An diese Brennkammer (2) anschließend und darunter ist die Abhitzezone (3) angeordnet. Die Wirbelscheiben (5) mit ihren Zwischenräumen (6) sorgen über die umlaufenden Rippen (7), die mit der Brennkammerwand (13) und der Abhitzezonenwand (15) auf der Wärmeträgerseite fest verbunden sind, für einen guten Wärmerübergang an den Wärmeträger (14). Die abgekühlten Abgase verlassen danach den Heizkessel über den Kondensatabscheider (8) und das Abgasrohr (9). Anfallendes Abgaskondensat wird über den Kondensatanschluß (12) abgeleitet. Die Wärmeträgerflüssigkeit tritt über den Rücklaufanschluß (10) in den Wärmeträgerraum ein und tritt beim Vorlaufanschluß (11) von diesem wieder aus. Der Kondensatabscheider (8) wird mit dem Flansch (19) am Heizkessel befestigt. Eine Halterung (20) sorgt für die mittige und sichere Auflage des Abstandhalter (18) der Wirbelscheiben (5). Eine Auflage (17) bewirkt, daß der Abstandhalter (18) wie vorgesehen in die Halterung (20) eintauchen kann. Einstellbare Zentrierhalter (21) im oberen Bereich der Abhitzezone (3) sorgen für eine genaue Zentrierung der Wirbelscheiben (5). Mindestens die erste Wirbelscheibe (5) nach der Brennkammer (2) ist ganzflächig mit einer Isolierung (16) versehen, um die vom Brenner (1) oder einem anderen Gerät kommende Wärme abzuleiten. Fig. 1 shows an embodiment of a boiler in a vertical construction. The burner (1) burns vertically into the combustion chamber (2). The heat recovery zone (3) is arranged below and below this combustion chamber (2). The swirl plates (5) with their gaps (6) ensure good heat transfer to the heat transfer medium (14) via the circumferential ribs (7), which are firmly connected to the combustion chamber wall (13) and the heat recovery zone wall (15) on the heat transfer medium side. , The cooled exhaust gases then leave the boiler via the condensate separator (8) and the exhaust pipe (9). Exhaust gas condensate is discharged via the condensate connection (12). The heat transfer fluid enters the heat transfer chamber via the return connection (10) and exits from the supply connection (11) again. The condensate separator (8) is attached to the boiler with the flange (19). A bracket (20) ensures the central and secure support of the spacer (18) of the swirl discs (5). A support (17) causes the spacer (18) to dip into the holder (20) as provided. Adjustable centering brackets (21) in the upper area of the waste heat zone (3) ensure precise centering of the swirl discs (5). At least the first swirl disk (5) after the combustion chamber (2) is provided with insulation (16) over the entire surface in order to dissipate the heat coming from the burner (1) or another device.

Fig. 2 zeigt ein Ausführungsbeispiel eines Heizkessels in horizontaler Bauweise. Ein Brenner (1) oder eine andere Wärmequelle brennt in die Brennkammer (2). An diese Brennkammer (2) schließt die Abhitzezone (3) an. Die Wirbelscheiben (5) mit ihren Zwischenräumen (6) sorgen über die Rippen (7), die mit der Brennkammerwand (13) und der Abhitzezonenwand (15) auf der Wärmeträgerseite fest verbunden sind, für einen guten Wärmeübergang an den Wärmeträger (14). Die abgekühlten Abgase verlassen danach den Heizkessel über den Kondensatabscheider (8) und das Abgasrohr (9). Anfallendes Abgaskondensat wird über den Kondensatanschluß (12) abgeleitet. Die Wärmeträgerflüssigkeit tritt über den Rücklaufanschluß (10) in den Wärmeträgerraum ein und tritt beim Vorlaufanschluß (11) aus diesem wieder aus. Der Kondensatabscheider (8) wird mit dem Flansch (19) am Heizkessel befestigt. Eine Halterung (20) sorgt für die mittige und sichere Auflage des Abstandhalters (18) der Wirbelscheiben (5). Eine Auflage (17) bewirkt, daß der Abstandhalter (18) wie vorgesehen in die Halterung (20) eintauchen kann. Einstellbare Zentrierhalter (21) im vorderen Bereich der Abhitzezone (3) sorgen für eine genau Zentrierung der Wirbelscheiben (5). Mindestens die erste Wirbelscheibe (5) nach der Brennkammer (2) ist ganzflächig mit einer Isolierung (16) versehen, um die vom Brenner (1) oder von einem anderen Gerät kommenden Wärme abzuleiten. Die Zentrierhalter (21) verhindern bei horizontaler Bauweise der Abhitzezone (3) gleichzeitig und mit Hilfe der Halter (22) ein ungewolltes verschieben der Wirbelscheiben (5). Fig. 2 shows an embodiment of a boiler in a horizontal design. A burner (1) or another heat source burns in the combustion chamber (2). The waste heat zone (3) connects to this combustion chamber (2). The swirl plates (5) with their gaps (6) ensure good heat transfer to the heat transfer medium (14) via the ribs (7), which are firmly connected to the combustion chamber wall (13) and the waste heat zone wall (15) on the heat transfer medium side. The cooled exhaust gases then leave the boiler via the condensate separator (8) and the exhaust pipe (9). Exhaust gas condensate is discharged via the condensate connection (12). The heat transfer fluid enters the heat transfer chamber via the return connection (10) and exits from the supply connection (11) again. The condensate separator (8) is attached to the boiler with the flange (19). A bracket (20) ensures the central and secure support of the spacer (18) of the swirl discs (5). A support (17) causes the spacer (18) to dip into the holder (20) as provided. Adjustable centering brackets (21) in the front area of the waste heat zone (3) ensure precise centering of the swirl discs (5). At least the first swirl disk (5) after the combustion chamber (2) is provided with insulation (16) over the entire surface in order to dissipate the heat coming from the burner (1) or from another device. With the horizontal design of the waste heat zone (3), the centering brackets (21) prevent the vortex disks (5) from being moved unintentionally and with the help of the brackets (22).

Fig.3 zeigt ein Ausführungsbeispiel eines Heizkessels in horizontaler Bauweise mit voneinander getrennter Brennkammer (2) und Abhitzezone (3). Ein Überleitungskanal (4) führt die Heißgase aus der Bennkammer (2) in die mittelbar anschließende Abhitzezone (3). In der Abhitzezone (3) geben die Abgase in bekannter Weise, wie beschrieben, ihre Wärme an den Wärmeträger (14) ab. Die Anordnung der Wirbelscheiben (5) mit den Zwischenräumen (6) ist bei dieser Konstruktion identisch mit der in der Fig. 2 beschriebenen, horizontalen Ausführung. Die Wirbelscheiben (5) werden in diesem Fall jedoch vom Überleitungskanal (4) her mit Wärme beaufschlagt. Die Abhitzezone (3) ist an ihrem vorderen Ende mit einer Tür (25) verschlossen. Die abgekühlten Abgase verlassen über den Abgas- und Kondensatableiter (23) die Abhitzezone (3). Diese gelangen über den Kondensatabscheider (8) zum Abgasrohr (9) und verlassen den Kessel. Anfallendes Abgaskondensat wird über den Kondensatanschluß (12) abgeleitet. Die Wärmeträgerflüssigkeit tritt über den Rücklaufanschluß (10) im vorderen Bereich der Abhitzezone (3) in den Wärmeträgerraum ein und tritt beim Vorlaufanschluß (11) im vorderen Bereich der Brennkammer (2) oben wieder aus. Vorne ist im Bereich der Türen. Der Kondensatabscheider (8) wird mit dem Flansch (19) am Heizkessel befestigt. Figure 3 shows an embodiment of a boiler in a horizontal design with separate combustion chamber (2) and heat recovery zone (3). A transfer duct (4) leads the hot gases from the brewing chamber (2) into the indirect heat recovery zone (3). In the waste heat zone (3), the exhaust gases give off their heat to the heat transfer medium (14) in a known manner, as described. The arrangement of the vertebral discs (5) with the spaces (6) in this construction is identical to the horizontal design described in FIG. 2. In this case, however, the vortex discs (5) are subjected to heat from the transfer duct (4). The waste heat zone (3) is closed at its front end with a door (25). The cooled exhaust gases leave the waste heat zone (3) via the exhaust gas and condensate drain (23). These pass through the condensate separator (8) to the exhaust pipe (9) and leave the boiler. Exhaust gas condensate is discharged via the condensate connection (12). The heat transfer fluid enters the heat transfer chamber via the return connection (10) in the front area of the waste heat zone (3) and exits again at the flow connection (11) in the front area of the combustion chamber (2). The front is in the area of the doors. The condensate separator (8) is attached to the boiler with the flange (19).
