Description

Die Erfindung betrifft einen Heizkessel mit

  • einem Wassermantel, der an eine Vor- und an eine Rücklaufleitung angeschlossen ist,
  • einer Brennkammer, die im oberen Bereich des Wassermantels angeordnet ist,
  • einem Brenner, der mit der Brennkammer verbunden ist, und
  • mindestens einem von der Brennkammer aus nach unten durch den Wassermantel hindurchgeführten Heizrohr, das mit einer Rauchgasleitung in Verbindung steht und eine Mehrzahl von Rauchgas-Leiteinsätzen enthält.
The invention relates to a boiler
  • a water jacket connected to a supply and a return line,
  • a combustion chamber, which is arranged in the upper area of the water jacket,
  • a burner connected to the combustion chamber, and
  • at least one heating pipe which is led downwards from the combustion chamber through the water jacket and which is connected to a flue gas line and contains a plurality of flue gas guide inserts.

Ein derartiger Heizkessel ist aus der EP 0 191 147 B1 bekannt. Er eignet sich gleichermaßen für Öl- und Gasfeuerung. 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.Such a boiler is from EP 0 191 147 B1 known. It is equally suitable for oil and gas firing. Different performance levels are possible the number of heating pipes being adjusted accordingly. The flue gas guide inserts leave the boiler as a condensing boiler work. However, an operation is also without Recovery of latent heat of condensation possible, if the chimney system requires higher flue gas temperatures. In in this case, the flue gas guide inserts at least partially removed.

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 side, heat-insulating lining. The Burner is located on the side of the boiler and penetrates with its burner tube the water jacket and the Sidewall 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 it was still efficient can be improved, while simplifying it at the same time the construction. The achievement of this goal forms the object underlying the invention.

Diese Aufgabe wird mit einem Heizkessel der eingangs genannten Art dadurch gelöst,

  • daß das Heizrohr nach oben über den Wassermantel hinausgeführt ist und mit seinem oberen Abschnitt die Brennkammer bildet und
  • daß der Brenner als Sturzbrenner ausgebildet und nach unten gerichtet auf dem oberen Ende des Heizrohres angeordnet ist.
This object is achieved with a boiler of the type mentioned in the introduction
  • that the heating tube is led up over the water jacket and forms the combustion chamber with its upper portion and
  • that the burner is designed as a fall burner and is directed downward on the upper end of the heating tube.

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 therefore blows the flue gas directly into the heating pipe into it, so that an energetically unfavorable deflection of the flue gas is eliminated. The entire heat input also takes place into the water jacket over the heating pipe. So it takes not the heating of a thermal surrounding the combustion chamber Insulation. The water jacket becomes unique penetrated by the heating tube. So there is no side Breakthrough of the well-known boiler, which served the Connect the burner to the combustion chamber. A considerable one constructive simplification is the result.

Die Rauchgas-Leiteinsätze können, wie auch bei der bekannten Konstruktion, topfförmig ausgebildet sein und mit ihrem oberen, radial nach außen abstehenden Rand an das Heizrohr angrenzen, 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 guide inserts can, as in the known Construction, pot-shaped and with its upper, radially outwardly projecting edge to the Adjacent the heating tube, being nozzle-like in its side wall Have passage openings. It is special advantageous that the top, the combustion chamber delimiting Leadership deeper than the following lead missions is trained. Accordingly, it also shows a higher one Number of nozzle openings. This takes into account the fact that the flue gases reach their maximum when they exit the flame Own volume.

Vorzugsweise ist das Heizrohr als einteiliger Mantel aus Edelstahl ausgebildet.The heating tube is preferably made as a one-piece jacket Stainless steel trained.

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 an essential further development of the invention proposed that the heating tube on a bottom plate of the 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 floor of the heating tube and passes into a lateral condensate drain pipe. The condensate is thus from the heating pipe directly into the drain 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 guide inserts can, as in the known Construction supported by a central pole be, it being particularly advantageous that the Support the rod on the condensate collecting tray. It deals a structurally particularly favorable 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 a further preferred feature, the Flue gas pipe above the condensate collecting tray on the side from the heating pipe. All pollutants are therefore from Heating pipe led directly out of the boiler without to charge further interior spaces of the boiler. This represents an extremely inexpensive for environmental reasons and thereby 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, you will be the boiler with a single Load the heating tube. Then stand for the performance level Heating pipes with different diameters and accordingly adapted flue gas guide inserts are available.

Die Erfindung wird im folgenden anhand eines bevorzugten Ausführungsbeispiels im Zusammenhang mit der beiliegenden Zeichnung näher erläutert. Die Zeichnung zeigt inThe invention is based on a preferred Embodiment in connection with the accompanying Drawing explained in more detail. The drawing shows in

Fig. 1 in schematischer Darstellung einen axialen Vertikalschnitt durch einen erfindungsgemäßen Heizkessel.Fig. 1 shows 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 one Contains water jacket 2. The water jacket 2 is on a flow 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 is heated by a heating pipe 5 enforced. The heating tube 5 is up over the water jacket 2 led out and forms with its upper section a combustion chamber for a fall 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 pipe 5 in.

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 contains a plurality of flue gas guide inserts 7, which are cup-shaped and with their Adjacent the upper, radially protruding edge to the heating pipe. They have nozzle-shaped openings in their side wall 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 progressively going from top to bottom Guided inside the guide inserts 7 and leaves them through the nozzle-like passage openings 8, with smoke gas jets form that on the inner surface of the water-cooled Hit the heating tube 5. The flue gas cools down progressively so strong that the condensable ones Components of the flue gas with appropriate heat emission 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 guide insert 7 is higher than the following leading missions and points accordingly also a larger number of nozzle-like openings 8 on. This takes into account the fact that the flue gas at the outlet of the fall 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 inside wall of the stainless steel manufactured, one-piece heating tube 5 down and meets an inclined condensate collecting tray 9 there passes into a condensate drain connector 10. Above the Condensate collecting base 9 branches a side flue gas line 11 from the heating tube 5. So all pollutants are from the heating pipe directly from the housing 1 of the boiler led out without further interior spaces of the boiler act upon.

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 sheet 12 of the Boiler. It also guides the weight of the flue gas guide inserts 7 in the base plate 12. The flue gas guide inserts 7 are namely attached to a central rod 13, which is supported on the condensate collecting base 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 should be operated from 150 ° C to 200 ° C, you open a cover 14, which carries the lintel 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 there are possibilities for modification given. So the boiler can with a plurality of heating pipes, each of which a condensate drain pipe and a flue gas pipe exhibit. However, it is cheaper to have a performance rating through heating pipes of different diameters and accordingly to achieve adapted flue gas guide inserts. The Flue gas guide inserts can be designed so that the condensate partly flows into the pilot operations and there again evaporates. The pollutants then form a crust the pot bottoms, which are easily removed during the course of maintenance can be. In the illustrated embodiment, one is exact vertical alignment of water jacket and heating pipe chosen. Angular deviations are equally possible, whereby however, the orientation is essentially vertical should stay.
