Description

Die Erfindung betrifft einen Heizkessel.The invention relates to a boiler.

Aus der AT 390 140 B ist ein Heizkessel bekannt, der einen Sturzbrenner aufweist. Der Sturzbrenner ist auf eine Wärmetauscheranordnung gerichtet, die aus zu einem Rohrbündel zusammengefaßten Rohren besteht und das Abgas des Brenners nach unten leitet. Die Wärmetauscheranordnung wird von Wasser umspült, das die Wärme von den Rohren aufnimmt.From AT 390 140 B a boiler is known, the having a tumble burner. The fall burner is on one Heat exchanger assembly directed to a tube bundle composed of tubes and the exhaust of the burner heads down. The heat exchanger assembly is of Water flows around, which absorbs the heat from the pipes.

Aus der US 4 380 215 A ist ebenfalls ein Heizkessel bekannt, der mit einem Sturzbrenner arbeitet. Der Sturzbrenner ist in ein Heizrohr gerichtet, das von einem Wassermantel umgeben ist. Der Sturzbrenner ist in seinem oberen Bereich isoliert, um eine Überhitzung des Wassers im oberen Bereich des Wassermantels zu vermeiden. Im unteren Bereich des Heizrohrs sind Luftleitbleche angeordnet, die die Strömung des Heizgases so leiten, daß die Gase unter den Wassermantel in eine Auffangkammer gebracht werden, um den Wassermantel von unten zu erhitzen.From US 4 380 215 A is also a boiler known working with a tumble burner. The fall burner is directed into a heating pipe by a water jacket is surrounded. The fall burner is in its upper Isolated area to overheat the water in the upper Area of the water jacket to avoid. In the area below of the heating tube baffles are arranged, which the flow of the fuel gas so that the gases under the water jacket be brought into a collection chamber to the water jacket to heat from below.

Aus der EP 0 191 147 B1 ist ein Heizkessel bekannt, der sich gleichermaßen für Öl- und Gasfeurung eignet. Dabei sind unterschiedliche Leistungsstufen möglich, wobei die Anzahl der Heizrohre entsprechend angepaßt wird. Die Rauchgas-Leiteinsätze lassen den Heizkessel als Brennwertgerät arbeiten. Allerdings ist auch ein Betrieb ohne Rückgewinnung der latenten Kondensationswärme möglich, sofern die Kaminanlage höhere Rauchgastemperaturen fordert. In diesem Falle werden die Rauchgas-Leiteinsätze zumindest teilweise entfernt.From EP 0 191 147 B1 a boiler is known which Equally suitable for oil and Gasfeurung. There are different power levels possible, the number the heating pipes is adjusted accordingly. The flue gas guiding inserts let the boiler work as condensing boiler. However, also a company without recovery of the latent heat of condensation possible, provided the chimney system higher flue gas temperatures calls. In this case will be the flue gas Leiteinsätze removed at least partially.

Die Brennkammer taucht von oben in den Wassermantel ein und besitzt eine seitliche, wärmedämmende Auskleidung. Der Brenner ist seitlich am Heizkessel angeordnet und durchdringt mit seinem Brennerrohr den Wassermantel sowie die Seitenwand der Brennkammer. The combustion chamber dips into the water jacket from above and has a lateral, heat-insulating lining. Of the Burner is arranged on the side of the boiler and penetrates with his burner tube the water jacket and the Side wall of the combustion chamber.

Der bekannte Heizkessel hat sich in der Praxis bewährt. Allerdings wurde gefunden, daß er wirkungsgradmäßig noch verbesserungsfähig ist, und zwar unter gleichzeitiger Vereinfachung der Konstruktion. Die Erreichung dieses Ziels bildet die der Erfindung zugrundeliegende Aufgabe.The well-known boiler has proven itself in practice. However, it was found that he still effective improvement, while simplifying it the construction. Achieving this goal forms the task underlying the invention.

Diese Aufgabe wird durch einen Heizkessel mit den Merkmalen des Patentanspruchs 1 gelöst.This task is performed by a boiler with the features of claim 1.

Der Brenner bläst also das Rauchgas direkt in das Heizrohr hinein, so daß eine energetisch ungünstige Umlenkung des Rauchgases entfällt. Auch erfolgt der gesamte Wärmeeintrag in den Wassermantel über das Heizrohr. Es bedarf also nicht der Aufheizung einer die Brennkammer umgebenden thermischen Isolierung. Der Wassermantel wird einzig und allein vom Heizrohr durchsetzt. Es entfällt also der seitliche Durchbruch des bekannten Heizkessels, der dazu diente, den Brenner mit der Brennkammer zu verbinden. Eine beträchtliche konstruktive Vereinfachung ist die Folge.The burner blows the flue gas directly into the heating tube into it, so that an energetically unfavorable deflection the flue gas is eliminated. Also, the entire heat input takes place in the water jacket over the heating tube. So it needs not the heating of a thermal surrounding the combustion chamber Insulation. The water jacket becomes unique penetrated by the heating tube. It therefore eliminates the lateral Breakthrough of the known boiler, which served the Burner to connect to the combustion chamber. A considerable one constructive simplification is the result.

Die Rauchgas-Leiteinsätze sind, wie auch bei der bekannten Konstruktion, topfförmig ausgebildet und grenzen mit ihrem oberen, radial nach außen abstehenden Rand an das Heizrohr an, wobei sie in ihrer Seitenwandung düsenartige Durchtrittsöffnungen aufweisen. Dabei ist es besonders vorteilhaft, daß der oberste, die Brennkammer begrenzende Leiteinsatz tiefer als die nachfolgenden Leiteinsätze ausgebildet ist. Er weist dementsprechend auch eine höhere Anzahl von Düsenöffnungen auf. Dies trägt dem Umstand Rechnung, daß die Rauchgase beim Austritt aus der Flamme ihr maximales Volumen besitzen.The flue gas Leiteinsätze are, as well as in the known Construction, cup-shaped and borders with their upper, radially outwardly projecting edge of the Heating tube, wherein it is nozzle-like in its side wall Have passage openings. It is special advantageous in that the uppermost, the combustion chamber limiting Leiteinsatz deeper than the following Leiteinsätze is trained. He has accordingly a higher one Number of nozzle openings. This takes into account the fact that the flue gases at the exit from the flame their maximum Own volume.

Vorzugsweise ist das Heizrohr als einteiliger Mantel aus Edelstahl ausgebildet.Preferably, the heating tube is designed as a one-piece jacket Stainless steel formed.

Dabei wird in wesentlicher Weiterbildung der Erfindung vorgeschlagen, daß das Heizrohr auf einer Bodenplatte des Heizkessels abgestützt ist. Dies ist statisch günstiger als eine Aufhängung im Inneren des Wassermantels. This is in essential development of the invention proposed that the heating tube on a bottom plate of Boiler is supported. This is statically cheaper than a suspension inside the water jacket.

Nach einem weiteren vorteilhaften Merkmal weist der Heizkessel einen zur Horizontalen geneigten Kondensat-Sammelboden auf, der einen Zwischenboden des Heizrohres bildet und in einen seitlichen Kondensat-Ablaufstutzen übergeht. Das Kondensat wird also aus dem Heizrohr direkt in den Ablaufstutzen eingeleitet.According to a further advantageous feature, the Boiler a condensate collecting tray inclined to the horizontal on, which forms an intermediate bottom of the heating tube and merges into a lateral condensate drain pipe. The condensate is thus from the heating tube directly into the outlet pipe initiated.

Die Rauchgas-Leiteinsätze können, wie auch bei der bekannten Konstruktion, von einer zentralen Stange getragen werden, wobei es besonders vorteilhaft ist, daß sich die Stange auf dem Kondensat-Sammelboden abstützt. Es handelt sich also um eine statisch besonders günstige Konstruktion.The flue gas Leiteinsätze can, as well as in the known Construction, carried by a central pole be, where it is particularly advantageous that the Rod supported on the condensate collecting tray. It deals So it is a statically very cheap construction.

Nach einem weiteren bevorzugten Merkmal zweigt die Rauchgasleitung oberhalb des Kondensat-Sammelbodens seitlich vom Heizrohr ab. Die gesamten Schadstoffe werden also vom Heizrohr aus direkt aus dem Heizkessel herausgeleitet, ohne weitere Innenräume des Heizkessels zu beaufschlagen. Dies stellt eine aus Umweltschutzgründen äußerst günstige und dabei extrem einfache Konstruktion dar.According to another preferred feature branches the Flue gas duct above the condensate collecting tray laterally from the heating tube. The total pollutants are thus from the Heating pipe out directly from the boiler, without to apply additional internal spaces of the boiler. This is a very environmentally friendly and beneficial extremely simple construction.

In aller Regel wird man den Heizkessesl mit einem einzigen Heizrohr bestücken. Zur Leistungsstufung stehen dann Heizrohre mit unterschiedlichem Durchmesser sowie entsprechend angepaßte Rauchgas-Leiteinsätze zur Verfügung.As a rule, one gets the Heizkessesl with a single Equip heating tube. For Leistungsstufung stand then Heating pipes with different diameters and accordingly adapted flue gas guide inserts available.

Die Erfindung wird im folgenden anhand eines bevorzugten Ausführungsbeispiels im Zusammenhang mit der beiliegenden Zeichnung näher erläutert. Die Zeichnung zeigt inThe invention will be described below with reference to a preferred Embodiment in conjunction with the attached Drawing explained in more detail. The drawing shows in

Fig. 1 in schematischer Darstellung einen axialen Vertikalschnitt durch einen erfindungsgemäßen Heizkessel.Fig. 1 in a schematic representation of an axial vertical section by a boiler according to the invention.

Der Heizkessel weist ein Gehäuse 1 auf, welches einen Wassermantel 2 enthält. Der Wassermantel 2 ist an eine Vorlaufleitung 3 sowie an eine Rücklaufleitung 4 angeschlossen.The boiler has a housing 1, which has a Water jacket 2 contains. The water jacket 2 is connected to a supply line 3 and connected to a return line 4.

Außerdem wird der Wassermantel 2 von einem Heizrohr 5 durchsetzt. Das Heizrohr 5 ist nach oben über den Wassermantel 2 hinausgeführt und bildet mit seinem oberen Abschnitt eine Brennkammer für einen Sturzbrenner 6. Dieser ist auf dem oberen Ende des Heizrohres 5 angeordnet. Der Sturzbrenner 6 bläst also die heißen Rauchgase direkt in das Heizrohr 5 hinein.In addition, the water jacket 2 by a heating tube. 5 interspersed. The heating tube 5 is up over the water jacket 2 led out and forms with its upper section a combustion chamber for a tumble burner 6. This is on the upper end of the heating tube 5 is arranged. The fall burner 6 thus blows the hot flue gases directly into the heating tube 5 into it.

Das Heizrohr 5 enthält eine Mehrzahl von Rauchgas-Leiteinsätzen 7, die topfförmig ausgebildet sind und mit ihrem oberen, radial abstehenden Rand an das Heizrohr angrenzen. In ihrer Seitenwand weisen sie düsenförmige Durchtrittsöffnungen 8 auf.The heating tube 5 includes a plurality of flue gas guiding inserts 7, which are cup-shaped and with their adjoin the upper, radially protruding edge of the heating tube. In their side wall they have nozzle-shaped openings 8 on.

Das Rauchgas wird fortschreitend von oben nach unten ins Innere der Leiteinsätze 7 gelenkt und verläßt diese durch die düsenartigen Durchtrittsöffnungen 8, wobei sich Rauchgasstrahlen bilden, die auf die Innenfläche des wassergekühlten Heizrohres 5 auftreffen. Das Rauchgas kühlt sich fortschreitend so stark ab, daß sich die auskondensierbaren Bestandteile des Rauchgases unter entsprechender Wärmeabgabe verflüssigen.The flue gas is progressing from top to bottom into the Interior of the Leiteinsätze 7 steered and leaves them the nozzle-like passage openings 8, wherein flue gas jets form on the inner surface of the water-cooled Heating tube 5 impinge. The flue gas cools progressively so strong that the auskondensierbaren Components of the flue gas with appropriate heat dissipation liquefy.

Der oberste Rauchgas-Leiteinsatz 7 ist höher ausgebildet als die nachfolgenden Leiteinsätze und weist dementsprechend auch eine größere Anzahl von düsenartigen Durchtrittsöffnungen 8 auf. Dies trägt dem Umstand Rechnung, daß das Rauchgas am Austritt des Sturzbrenners 6 sein maximales Volumen besitzt.The uppermost flue gas Leiteinsatz 7 is formed higher as the subsequent lead inserts and points accordingly also a larger number of nozzle-like passages 8 on. This takes into account the fact that the flue gas at the outlet of the tumble burner 6 has its maximum volume.

Das Kondensat läuft an der Innenwand des aus Edelstahl hergestellten, einteiligen Heizrohres 5 nach unten und trifft dort auf einen geneigten Kondensat-Sammelboden 9, der in einen Kondensat-Ablaufstutzen 10 übergeht. Oberhalb des Kondensat-Sammelbodens 9 zweigt eine seitliche Rauchgasleitung 11 vom Heizrohr 5 ab. Sämtliche Schadstoffe werden also vom Heizrohr aus direkt aus dem Gehäuse 1 des Heizkessels herausgeleitet, ohne weitere Innenräume des Heizkessels zu beaufschlagen.The condensate runs on the inner wall of the stainless steel manufactured, one-piece heating tube 5 down and there meets an inclined condensate collection tray 9, the merges into a condensate drain neck 10. Above the Condensate collecting tray 9 branches a lateral flue gas line 11 from the heating tube 5 from. All pollutants are so from the heating pipe directly from the housing 1 of the boiler led out, without further interior of the boiler apply.

Das Heizrohr 5 stützt sich auf einer Bodenblatte 12 des Heizkessels ab. Dabei leitet es auch das Gewicht der Rauchgas-Leiteinsätze 7 in die Bodenplatte 12 ein. Die Rauchgas-Leiteinsätze 7 sind nämlich an einer zentralen Stange 13 befestigt, die sich auf dem Kondensat-Sammelboden 9 abstützt. The heating tube 5 is supported on a bottom plate 12 of the Boiler off. It also directs the weight of the flue gas Leiteinsätze 7 in the bottom plate 12 a. The flue gas guiding inserts 7 are in fact attached to a central rod 13, which is supported on the condensate collection tray 9.

Wenn der Heizkessel konventionell mit Rauchgastemperaturen von 150°C bis 200°C betrieben werden soll, öffnet man einen Deckel 14, der den Sturzbrenner 6 trägt, und entfernt die Rauchgas-Leiteinsätze 7 zusammen mit deren zentraler Stange 13.If the boiler is conventional with flue gas temperatures to be operated from 150 ° C to 200 ° C, one opens a lid 14, which carries the tumble burner 6, and removed the flue gas guide inserts 7 together with their central Rod 13.

Im Rahmen der Erfindung sind durchaus Abwandlungsmöglichkeiten gegeben. So kann der Heizkessel mit einer Mehrzahl von Heizrohren bestückt werden, wobei diese jeweils einen Kondensat-Ablaufstutzen sowie eine Rauchgasleitung aufweisen. Günstiger allerdings ist es, eine Leistungsstufung durch Heizrohre unterschiedlichen Durchmessers und entsprechend angepaßter Rauchgas-Leiteinsätze zu erzielen. Die Rauchgas-Leiteinsätze können so gestaltet sein, daß das Kondensat zum Teil in die Leiteinsätze einströmt und dort wieder verdampft. Die Schadstoffe bilden dann eine Kruste auf den Topfböden, die im Zuge der Wartung problemlos entfernt werden kann. Bei der dargestellten Ausführungsform ist eine exakt vertikale Ausrichtung von Wassermantel und Heizrohr gewählt. Winkelabweichungen sind gleichermaßen möglich, wobei allerdings die Ausrichtung im wesentlichen vertikal bleiben sollte.Within the scope of the invention are quite modification possibilities given. So the boiler can with a majority be fitted by heating pipes, these each a condensate drain pipe and a flue gas pipe exhibit. Cheaper, however, it is a Leistungsstufung by heating pipes of different diameters and accordingly to achieve adapted flue gas Leiteinsätze. The Flue gas guide inserts can be designed so that the condensate Partly flows into the Leiteinsätze and there again evaporated. The pollutants then form a crust the pot bottoms, which are easily removed in the course of maintenance can be. In the illustrated embodiment is a exact vertical alignment of water jacket and heating tube selected. Angular deviations are equally possible, where however, the orientation is essentially vertical should stay.
