Vorrichtung zur Wärmerückgewinnung aus Rauchgasen in dem Zug eines SchornsteinsDevice for heat recovery from flue gases in the flue of a chimney
Die Erfindung betrifft eine Vorrichtung zur Wärmerückgewinnung aus Rauchgasen in dem Zug eines Schornsteins.The invention relates to a device for heat recovery from flue gases in the draft of a chimney.
Bei den bekannten Niedertemperatur- oder Brennwertkesseln in Wohnhäusern ist die Wärme des Rauchgases derart gering, dass sich eine Wärmerückgewinnung im eigentlichen Sinn nicht lohnt. Allerdings lohnt sich eine Wärmerückgewinnung dann, wenn: derartige Heizsysteme nicht zum Einsatz kommen.In the well-known low-temperature or condensing boilers in residential buildings, the heat of the flue gas is so low that heat recovery is not actually worthwhile. However, heat recovery is worthwhile if: such heating systems are not used.
Die Rauchgase, insbesondere von Kaminen oder auch Kachelöfen, die mit Kohle oder Holz befeuert werden, weisen eine nicht unerhebliche Abgastemperatur auf.The flue gases, especially from fireplaces or tiled stoves that are fired with coal or wood, have a not insignificant exhaust gas temperature.
Ziel der Erfindung ist nunmehr die Wärmerückgewinnung der Restwärme derartiger Abgase aus Kaminen oder Schornsteinen von Feuerstellen, die beispielsweise mit Kohle oder Holz befeuert werden.The aim of the invention is now the heat recovery of the residual heat of such exhaust gases from fireplaces or chimneys of fireplaces that are fired with coal or wood, for example.
Eine Vorrichtung zur Wärmerückgewinnung der eingangs genannten Art zeichnet sich erfindungsgemäß durch einen in dem Zug angeordneten flüssigkeitsdurchströmten Wärmetauscher aus. Die in dem Wärmetauscher geförderte Flüssigkeit wird durch die Rauchgase, die mit dem Wärmetauscher in Berührung kommen, erwärmt, und kann dem normalen Heizungssystem mittelbar oder unmittelbar zugeführt werden. Denkbar ist auch, die aus dem Rauchgas gewonnene Wärme zunächst beispielsweise einer Wärmepumpe zuzuführen, die diese Wärme als Primärenergie nutzen kann.A device for heat recovery of the type mentioned at the beginning is characterized according to the invention by a heat exchanger through which liquid flows and which is arranged in the flue. The liquid conveyed in the heat exchanger is heated by the flue gases that come into contact with the heat exchanger and can be fed directly or indirectly to the normal heating system. It is also conceivable to initially feed the heat obtained from the flue gases to a heat pump, for example, which can use this heat as primary energy.
Nach einer ersten Ausführungsform ist vorgesehen, dass der Wärmetauscher mindestens eine in dem Zug des Schornsteins wendelartig verlegte Rohrschlange umfasst. Eine solche flüssigskeitsdurchströmte Rohrschlange kann Wärme aus dem Rauchgas aufnehmen und über die Flüssigkeit dem normalen Heizungssystem mit Heizkörpern oder der Fussbodenheizung wieder zuführen.According to a first embodiment, the heat exchanger comprises at least one pipe coil laid in a spiral manner in the chimney flue. Such a pipe coil with a liquid flowing through it can absorb heat from the flue gas and feed it back into the normal heating system with radiators or the underfloor heating via the liquid.
Nach einer besonderen Variante dieser Ausführungsform ist vorgesehen, dass der Zug des Schornsteins ein Einsatzrohr aufweist, das radial beabstandet: zu der Innenwandung des Zuges in dem Zug angeordnet ist, wobei die Rohrschlange in dem Zwischenraum zwischen Zug und Einsatzrohr vorzugsweise am Einsatzrohr anliegend angeordnet ist.According to a particular variant of this embodiment, it is provided that the flue of the chimney has an insert pipe which is arranged in the flue at a radial distance from the inner wall of the flue, wherein the pipe coil is arranged in the space between the flue and the insert pipe, preferably adjacent to the insert pipe.
• ··
Vorteilhaft hierbei ist, dass die Wendel des Rohres nicht unmittelbar mit dem Rauchgas in Verbindung steht, und somit nicht die Gefahr der Verschmutzung besteht. Denn eine verruste Wendel weist einen schlechten Wärmeübergangswert auf.The advantage here is that the spiral of the pipe is not directly connected to the flue gas, and therefore there is no risk of contamination. This is because a rusty spiral has a poor heat transfer value.
Des Weiteren besteht hierbei nicht die Gefahr, dass die Wendel beim Reinigen des Schornsteins beschädigt wird. Hierbei ist weiterhin vorgesehen, dass das Einsatzrohr einen Einlass für die Rauchgase, beispielsweise vom Kamin oder einer anderen Brennstelle aus aufweist.Furthermore, there is no risk of the coil being damaged when cleaning the chimney. It is also intended that the insert pipe has an inlet for the flue gases, for example from the fireplace or another combustion source.
Eine zweite Ausführungsform zeichnet sich dadurch aus, dass der Wärmetauscher zwei beabstandet zueinander angeordnete Rohre als Doppelrohr umfasst, die bis auf den Ein- und Auslass für die Flüssigkeit allseitig verschlossen sind. Hierbei erfolgt die Übertragung der Wärme von den Rauchgasen zu. der in dem Doppelrohr geführten Flüssigkeit über die Wandung des inneren Rohres. Auch das Doppelrohr ist mit einem Einlass für die Rauchgase versehen.A second embodiment is characterized in that the heat exchanger comprises two pipes arranged at a distance from one another as a double pipe, which are closed on all sides except for the inlet and outlet for the liquid. The heat is transferred from the flue gases to the liquid guided in the double pipe via the wall of the inner pipe. The double pipe is also provided with an inlet for the flue gases.
Grundsätzlich gilt bei beiden Ausführungsformen, dass der Zu- und der Ablauf für das flüssige Medium in unterschiedlicher Höhe am Wärmetauscher angeordnet ist, um eine bestmögliche Durchströmung des Wärmetauschers zu bewerkstelligen.In both designs, the inlet and outlet for the liquid medium are arranged at different heights on the heat exchanger in order to achieve the best possible flow through the heat exchanger.
Anhand der Zeichnungen wird die Erfindung nachstehend beispielhaft näher erläutert.The invention is explained in more detail below with reference to the drawings.
Figur 1 zeigt eine erste Ausführungsform mit einer gewendeltenFigure 1 shows a first embodiment with a coiled
Rohrschlange;pipe coil;
Figur 2 zeigt eine zweite Ausführungsform mit einem Doppelrohr.Figure 2 shows a second embodiment with a double pipe.
Der insgesamt mit 1 bezeichnete Zug des Schornsteins weist gemäß Fig. 1 ein Einsatzrohr 2 auf, das beabstandet zu dem Zug 1 des Schornsteins in dem Zug des Schornsteins angeordnet ist. In dem Zwischenraum zwischen dem Einsatzrohr und dem Zug befindet sich mindestens eine, vorzugsweise jedoch vier oder mehrere wendelartig geformte Rohrschlangen 10 mit einem Zulauf, der durch den Pfeil 11 gekennzeichnet ist, und einem Ablauf, der durch den Pfeil 12 gekennzeichnet ist. Der Einlass für die Rauchgase ist mit 15 bezeichnet. Die Rohrschlange muss zum besseren Wärmeübergang unmittelbar an dem Einsatzrohr 2 anliegen.According to Fig. 1, the chimney flue, designated as 1, has an insert pipe 2 which is arranged in the chimney flue at a distance from the chimney flue 1. In the space between the insert pipe and the flue there is at least one, but preferably four or more spiral-shaped pipe coils 10 with an inlet, which is marked by the arrow 11, and an outlet, which is marked by the arrow 12. The inlet for the flue gases is designated by 15. The pipe coil must lie directly against the insert pipe 2 for better heat transfer.
Bei der Ausführungsform gemäß Fig. 2 zeigt der insgesamt mit 1 bezeichnete Zug das mit 20 bezeichnete Doppelrohr mit den beiden einzelnen Rohren 21 und 22. In dem Hohlraum 25 des Doppelrohres befindet sich eine Flüssigkeit, z. B. Wasser, die durch die im Inneren des Doppelrohres durchgeführten Rauchgase, die durch den Einlass 30 in das Innere des Doppelrohres gelangen, erwärmt wird. Das Doppelrohr 20 zeigt einen Einlass 26 und einen Auslass 27, die auf unterschiedlicher Höhe am Doppelrohr angeordnet sind.In the embodiment according to Fig. 2, the flue, designated as a whole with 1, shows the double pipe, designated with 20, with the two individual pipes 21 and 22. In the cavity 25 of the double pipe there is a liquid, e.g. water, which is heated by the flue gases that pass through the interior of the double pipe and enter the interior of the double pipe through the inlet 30. The double pipe 20 shows an inlet 26 and an outlet 27, which are arranged at different heights on the double pipe.
