Description

Heizkessel boiler
Die Erfindung betrifft einen Heizkessel mit einer vorzugsweise als Sturzbrennkammer ausgebildeten Brennkammer, die von einem einen Wärmeträger führenden von einer Kesselinnenwand und einer Kesselaußenwand begrenzten, der Strahlungszone zugeordneten Mantelraum umgeben ist, einen Kammerboden aufweist und über eine Abgasleitung sowie über Ab- gasrohre mit einem Kamin verbindbar ist.The invention relates to a heating boiler with a combustion chamber, preferably designed as a lintel combustion chamber, which is surrounded by a jacket space which defines a heat transfer medium and is delimited by an inner wall and an outer wall of the boiler and is assigned to the radiation zone, has a chamber floor and can be connected to a chimney via an exhaust pipe and exhaust pipes is.
Derartige Heizkessel und insbesondere auch Heizkessel mit Sturzbrenner sind bekannt und in Benutzung, so daß es diesbezüglich keines besonderen druckschriftlichen Hinweises bedarf. Das Grundprinzip derartiger Heizkessel besteht darin, daß sich an die Sturzbrennkammer nach unten orientierte Heizgaszüge anschließen, die in einer Abgassammeikammer enden. Die bekannten Konstruktionen sind aufwendig und teuer, um auf die gewünschten Ergebnisse hinsichtlich einer möglichst guten Brennstoffausnutzung zu kommen.Such boilers and in particular boilers with lintel burners are known and in use, so that no special written reference is required in this regard. The basic principle of such boilers is that the downward combustion chamber is followed by hot gas flues which end in an exhaust gas collection chamber. The known constructions are complex and expensive in order to achieve the desired results with regard to the best possible use of fuel.
Der Erfindung liegt demgemäß die Aufgabe zugrunde, einen Heizkessel der eingangs genannten Art dahingehend zu verbessern, daß Brennstoffe mit gutem Wirkungsgrad bei einfacher Konstruktion des Kessels genutzt werden können.The invention is therefore based on the object to improve a boiler of the type mentioned in such a way that fuels with good efficiency can be used with a simple construction of the boiler.
Diese Aufgabe wird nach der Erfindung im wesentlichen dadurch gelöst, daß der Mantelraum unter dem Brennkammerboden mit an der Kesselinnenwand vorgesehenen Kühlrippen, die in Strömungsrichtung der Abgase geneigte Schlitze aufweisen, eine Konvektionszone bildet, in der die durch die Kühlrippen aufgenommene Wärme über mit der Kesselinnenwand fest verbundene Führungsrippen an den Wärmeträger weitergegeben wird.This object is achieved according to the invention essentially in that the casing space under the combustion chamber floor with cooling fins provided on the inner wall of the boiler, which have slots inclined in the flow direction of the exhaust gases, forms a convection zone in which the the heat absorbed by the cooling fins is passed on to the heat transfer medium via guide fins which are firmly connected to the inner wall of the boiler.
Nach der Erfindung ausgebildete Heizkessel können sowohl als Niedertemperaturheizkessel als auch als Heizkessel mit Kondensatsammlung und ggf. Kondensatableitung ausgestaltet sein. Im Falle eines Niedertemperatur-Heizkessels wird die Ausgestaltung und Dimensionierung so gewählt, daß die sich auf ihrem Weg zum Abgaskamin abkühlenden Heizgase den Taupunkt nicht unterschreiten. Wird die Ausgestaltung so getroffen, daß die Abgase unter dem Taupunkt abgekühlt werden, dann wird der Heizkessel mit einer entsprechenden Abgasleitung bzw. Auffangwanne ausgestattet.Boilers designed according to the invention can be designed both as low-temperature boilers and as boilers with condensate collection and possibly condensate drainage. In the case of a low-temperature boiler, the design and dimensioning is chosen so that the heating gases cooling on their way to the flue gas chimney do not fall below the dew point. If the design is such that the exhaust gases are cooled below the dew point, the boiler is equipped with an appropriate exhaust pipe or drip pan.
Der Boden der Brennkammer, insbesondere Sturzbrennkammer, ist im wesentlichen flach ausgeführt und ist mit isolierenden Stoffen belegt. Der Brennkammerboden trägt eine Blechform, die erzwingt, daß die warmen Abgase nahe den Kühlrippen geleitet werden. Gleichzeitig trennt der Boden der Sturzbrennkammer die warme Strahlungszone des Heizkessels vom Konvektionsteil des Heizkessels.The bottom of the combustion chamber, in particular the lint combustion chamber, is essentially flat and is covered with insulating materials. The combustion chamber floor has a sheet metal shape, which forces the warm exhaust gases to be conducted near the cooling fins. At the same time, the bottom of the lintel combustion chamber separates the warm radiation zone of the boiler from the convection part of the boiler.
Durch eine Einengung des Strömungsquerschnittes am Rand des Brennkammerbodens, d.h. beim Übergang von der Strahlungszone des Heizkessels zur Konvektionszone des Heizkessels, entsteht eine intensive Verwir- belung der Heizgase. Dies bewirkt einen guten Wärmeübergang zu den mit Kühlrippen versehenen Innenwänden des Heizkessels. Die von den Kühlrippen aufgenommene Wärme wird durch die Innenwände des Heizkessels und den daran fest angebrachten Führungsrippen großflächig an den Wärmeträger abgegeben. Die Heizgase werden dabei abgekühlt, und je nach Auslegung des Kessels können die Heizgase den Heizkessel mit einer über dem Taupunkt gelegenen Temperatur verlassen oder als unter den Taupunkt abgekühlte Abgase, wobei in diesem Falle die Abgasleitung als Kondensat-Auffangwanne ausgebildet ist.A narrowing of the flow cross-section at the edge of the combustion chamber floor, ie at the transition from the radiation zone of the boiler to the convection zone of the boiler, results in an intensive swirling of the heating gases. This causes good heat transfer to the inside walls of the boiler, which are provided with cooling fins. The heat absorbed by the cooling fins is dissipated over a large area through the inner walls of the boiler and the guide fins attached to the heat transfer medium. The heating gases are cooled down, and each After the boiler has been designed, the heating gases can leave the boiler at a temperature above the dew point or as exhaust gases cooled below the dew point, in which case the flue gas pipe is designed as a condensate collecting trough.
Direkt anschließend an den Heizkessel befindet sich die mit einer gasdichten Flanschverbindung zum Heizkessel versehene Abgasleitung mit Putzöffnung. Über diese Abgasleitung und die als Rohrleitung ausgebildete Zuleitung zum Kamin werden die Abgase in einer gasdichten Leitung zum Kamin geleitet. Wird der Heizkessel nicht als Niedertemperaturkessel ohne Kondensatausfall, sondern als Kessel mit unter den Taupunkt abgekühlten Abgasen betrieben, dann wird die anfallende Kondensatflüssigkeit in den Kondensatbehälter geleitet und von da aus einer Verwertung oder Entsorgung zugeführt.Immediately after the boiler is the flue gas pipe with cleaning opening, which is provided with a gas-tight flange connection to the boiler. The exhaust gases are conducted in a gas-tight line to the chimney via this exhaust line and the supply line to the chimney designed as a pipeline. If the boiler is not operated as a low-temperature boiler without condensate failure, but rather as a boiler with flue gases that have cooled below the dew point, the resulting condensate liquid is fed into the condensate container and from there it is recycled or disposed of.
Die Erfindung wird im folgenden anhand eines Ausführungsbeispiels unter Bezugnahme auf die Zeichnung näher erläutert; in dieser zeigt:The invention is explained below using an exemplary embodiment with reference to the drawing; in this shows:
Fig. 1 eine Schnittdarstellung einer ersten Ausführungsform desFig. 1 is a sectional view of a first embodiment of the
Heizkessels.Boiler.
Nach Fig. 1 umfaßt der dargestellte Heizkessel einen Brennerflansch 1 , eine Sturzbrennkammer 2 mit der Brennkammer-Innenwand 3 und der Kesselaußenwand 1 1 zur Aufnahme des Wärmeträgers 4, den Sturzbrennkammerboden 5 mit den Überströmöffnungen 6 am Rand des Brennkammerboden 5, den Kühlrippen 7 mit in Strömungsrichtung der Abgase geneigten Schlitzen, den Führungsrippen 8 für den Wärmeträger 4, die Wärmeträger-Zuleitung 9 und die Wärmeträger- Ausleitung 10. Unter dem Heizkessel ist die Abgasleitung 12 mit einer Putzöffnung 13 angeordnet. Der Raum unter der Abgasleitung 12 ist für die optimale Aufnahme eines Kondensatbehälters 14 vorgesehen. Die Abgase werden in einer gasdichten Abgasleitung 12 und den gasdicht verbundenen Abgas- rohren 15 zum Kamin geleitet.According to Fig. 1, the boiler shown comprises a burner flange 1, a lint combustion chamber 2 with the inner wall 3 of the combustion chamber and the outer wall 1 1 for receiving the heat transfer medium 4, the lint combustion chamber bottom 5 with the overflow openings 6 at the edge of the combustion chamber bottom 5, the cooling fins 7 with in Flow direction of the exhaust gas inclined slots, the guide ribs 8 for the heat transfer medium 4, the heat transfer line 9 and the heat transfer line 10. The flue gas pipe 12 with a cleaning opening 13 is arranged under the boiler. The space under the exhaust pipe 12 is provided for the optimal reception of a condensate container 14. The exhaust gases are conducted to the chimney in a gas-tight exhaust pipe 12 and the gas-tightly connected exhaust pipes 15.
Der Abstand zwischen dem Brennkammerboden 5 und den Kühlrippen 7 kann über Distanzorgane definiert vorgegeben werden. Ebenso ist es möglich, den freien Durchtrittsquerschnitt der Überströmöffnung 6 definiert vorzugeben, insbesondere durch Vorgabe des Durchmessers des Brennkammerbodens, wobei diese Vorgabe in Abhängigkeit von der gewünschten Betriebsweise des Heizkessels erfolgen kann.The distance between the combustion chamber base 5 and the cooling fins 7 can be defined in a defined manner by means of spacers. It is also possible to define the free passage cross section of the overflow opening 6 in a defined manner, in particular by specifying the diameter of the combustion chamber floor, this specification being able to be made as a function of the desired mode of operation of the boiler.
Der gute Wirkungsgrad des Heizkessels ist insbesondere eine Folge davon, daß die aufgrund ihrer dichten Packung eine große Wärmetauscherfläche aufweisenden Kühlrippen 7 unmittelbar mit der Brennkammer- Innenwand 3 verbunden und vorzugsweise verschweißt sind und die Brennkammer-Innenwand auf ihrer anderen Seite mit den Führungsrippen 8 verbunden, insbesondere durch Schweißung verbunden ist, so daß optimale Wärmeübertragungseigenschaften erhalten werden. Da die Führungsrippen 8 einen wendeiförmigen Verlauf besitzen und der Strömungsquerschnitt nach oben hin größer wird, kann die bestmögliche Aufheizung des Wärme trägers 4 erreicht werden.The good efficiency of the boiler is in particular a consequence of the fact that the cooling fins 7, which have a large heat exchanger area due to their dense packing, are directly connected and preferably welded to the combustion chamber inner wall 3 and the other side of the combustion chamber inner wall is connected to the guide fins 8, is connected in particular by welding, so that optimal heat transfer properties are obtained. Since the guide ribs 8 have a helical shape and the flow cross section becomes larger towards the top, the best possible heating of the heat carrier 4 can be achieved.
Zwischen den Führungsrippen 8 können weitere Wärmeübertragungsrippen vorgesehen sein, die in den Strömungskanal ragen, sich aber nicht bis zur Kesselaußenwand 11 erstrecken. Durch Dimensionierung und/ oder Formgebung des Spaltes bzw. der Verengung 6 kann eine gezielte Verwirbelung der Heizgase auf ihrem Weg zur Abgasleitung erreicht werden. Dies fördert die Wärmeübertragung auf die Rippen 7 und trägt damit zur Steigerung des Wirkungsgrades bei. Beispielsweise kann die Abmessung der Verengung 6 in Radialrichtung im Bereich von etwa 3 bis 10 mm liegen. Vorzugsweise beträgt dieses Maß etwa 5 mm.Additional heat transfer ribs can be provided between the guide ribs 8, which protrude into the flow channel, but do not extend to the outer wall 11 of the boiler. By dimensioning and / or shaping the gap or the constriction 6, a targeted swirling of the heating gases can be achieved on their way to the exhaust pipe. This promotes heat transfer to the fins 7 and thus contributes to increasing the efficiency. For example, the dimension of the constriction 6 in the radial direction can be in the range of approximately 3 to 10 mm. This dimension is preferably about 5 mm.
Die in den Kühlrippen 7 vorgesehenen Schlitze verhindern zum einen das Auftreten von ggf. zu Abrißeffekten führenden Spannungen und stellen aufgrund ihrer Neigung zum anderen sicher, daß evtl. auftretendes Kondensat radial nach innen geleitet wird und dort am Beginn des offenen Schlitzes abtropfen kann. The slots provided in the cooling fins 7 prevent, on the one hand, the occurrence of stresses which may lead to tearing effects and, on the other hand, due to their tendency, ensure that any condensate which may occur is directed radially inwards and can drip off there at the beginning of the open slot.
