Description
Die Erfindung betrifft einen Festbrennstoffheizkessel gemäß dem Oberbegriff des unabhängigen Patentanspruchs 1.The invention relates to a solid fuel boiler according to the preamble of
Ein Festbrennstoffheizkessel der genannten Art ist nach der
Ausgehend vom Festbrennstoftheizkessel nach der
Auch liegt der Erfindung die Aufgabe zugrunde, bei einem Heizkessel dieser Art die Rückführung des Wärmeträgermediums vom Rücklaufanschluss zur äußeren Strömungszone zu verbessern, und zwar insbesondere unter strömungs- und fertigungstechnischen Aspekten.The invention is also based on the object to improve the return of the heat transfer medium from the return port to the outer flow zone in a boiler of this type, in particular under flow and manufacturing aspects.
Diese Aufgabe ist mit einem Festbrennstoffheizkessel der eingangs genannten Art nach der Erfindung durch die im Kennzeichen des unabhängigen Patentanspruchs 1 angeführten Merkmale gelöst.This object is achieved with a solid fuel boiler of the type mentioned according to the invention by the features cited in the characterizing part of the
Nach der Erfindung ist also vorgesehen, dass die Brennkammer längs ihrer vertikalen Erstreckung und bezogen auf ihren Umfang mindestens teilweise von einer inneren und einer äußeren Strömungszone für das Wärmeträgermedium umschlossen ist, dass die Strömungszonen mindestens an einem ihrer Enden miteinander verbunden und durch eine sich längs der Brennkammer erstreckende Trennwand voneinander getrennt sind, und dass die innere Strömungszone mit dem Vorlaufanschluss und die äußere Strömungszone mit dem Rücklaufanschluss fluidverbunden ist, und dass der Rücklaufanschluss mit einem mit mehreren in die äußere Strömungszone gerichteten Ausströmöffnungen versehen, an einem Endrand der Trennwand angeordneten und rohrförmig ausgebildeten Rücklaufverteiler verbunden ist.According to the invention, it is thus provided that the combustion chamber is at least partially enclosed along its vertical extension and relative to its circumference by an inner and an outer flow zone for the heat transfer medium, that the flow zones at least at one end connected to each other and through a along the Combustion wall extending partition wall are separated from each other, and that the inner flow zone with the flow connection and the outer flow zone with the return port is fluidly connected, and that the return port provided with a plurality of directed into the outer flow zone outflow, arranged at an end edge of the partition wall and tubular Return manifold is connected.
Nach der Erfindung ist also mit anderen worten vorgesehen, dass unter Einbezug auch der Brennkammer in einen wasserführenden Teil des Gehäuses in diesem wasserführenden Teil eine Trennwand angeordnet ist, die die Brennkammer mindestens teilweise mit einem gewissen Abstand umfasst, wobei die Trennwand die erste, innere, mit dem Vorlaufanschluss in Verbindung stehende, der Brennkammer unmittelbar benachbarte Strömungszone und die zweite, äußere, nun die Trennwand umfassende Strömungszone definiert, wobei an einem Ende der Trennwand ein die Rücklaufströmung in die zweite, äußere Strömungszone richtender hier so genannter Rücklaufverteiler angeordnet ist. Die Trennwand erstreckt sich dabei im Wesentlichen über die ganze Höhe der Brennkammer und ihre unteren und oberen Endränder erstrecken sich horizontal im Gehäuse.According to the invention, it is therefore provided in other words that, including the combustion chamber in a water-conducting part of the housing in this water-bearing part, a partition wall is arranged, which comprises the combustion chamber at least partially with a certain distance, wherein the partition wall, the first, inner, associated with the flow connection, the combustion chamber immediately adjacent flow zone and the second, outer, now the partition wall flow zone defined, wherein at one end of the partition a return flow in the second outer flow zone directing here so-called return manifold is arranged. The partition wall extends substantially over the entire height of the combustion chamber and its lower and upper end edges extend horizontally in the housing.
Wesentliches Merkmal ist dabei neben der direkten Bespülung der Brennkammerwand mit der inneren Strömungszone des Wärmeträgermediums und die Ausgestaltung der Rücklaufführung, d.h., bezüglich der vertikalen Brennkammerwand wird dafür gesorgt, dass diese weitestgehend von der inneren Strömungszone umgeben ist und, durch die Trennwand abgetrennt, eine äußere kalte Zone vorliegt, in die das kalte Rücklaufwasser durch den entsprechend ausgebildeten und angeordneten Rücklaufverteiler gezielt eingeleitet und damit von der Wand der Brennkammer ferngehalten wird. Eine Direktbeaufschlagung der Brennkammerwand mit kaltem Rücklauf ist damit unterbunden, und außerdem ist damit den Kondensations-und Korrosionsschutzerfordernissen genügt. Den natürlichen Auftriebstendenzen folgend, wird dabei eine Ausführungsform bevorzugt, bei der der Rücklaufverteiler am oberen Ende der Trennwand angeordnet ist und damit der Rücklauf von oben her in die äußere kalte Zone gelangt, in der der kalte Rücklauf nach unten strömt, dort in die heiße Zone überströmt und in dieser nach oben längs der Brennkammerwand abströmt.An essential feature is in addition to the direct Bespülung the combustion chamber wall with the inner flow zone of the heat transfer medium and the design of the return line, ie, with respect to the vertical combustion chamber wall is ensured that it is largely surrounded by the inner flow zone and separated by the partition, an outer cold zone is present, in which the cold return water through the appropriately designed and arranged return manifold specifically introduced and thus kept away from the wall of the combustion chamber. A direct loading of the combustion chamber wall with cold return is thus prevented, and also it is sufficient for the condensation and corrosion protection requirements. Following the natural buoyancy tendencies, an embodiment is preferred in which the return manifold is arranged at the upper end of the partition and thus the return passes from above into the outer cold zone, in which the cold return flows down, there in the hot zone flows over and flows upwards in this along the combustion chamber wall.
Vom Festbrennstoffheizkessel nach der
Weitere vorteilhafte Ausführungsformen des erfindungsgemäßen Festbrennstoffheizkessels bestehen in Folgendem:
- Um eine möglichst gleichmäßige Verteilung des Rücklaufes in die äußere kalte Zone zu gewährleisten, ist der Rücklaufverteiler mit mehreren, gleichmäßig über seine ganze Länge verteilten, düsenartigen Öffnungen versehen.
- In order to ensure a uniform distribution of the return flow in the outer cold zone, the return manifold is provided with a plurality of evenly distributed over its entire length, nozzle-like openings.
Abgesehen von einer baulichen Erleichterung und auch größerer Druckstabilität der ganzen Kesselkonstruktion sind ebenfalls mit Rücksicht auf eine gleichmäßige Verteilung die Brennkammer, die Trennwand, das diese aufnehmende Gehäuse und letztlich auch der Rücklaufverteiler im Horizontalschnitt bzw. in Draufsicht vorzugsweise kreisförmig bzw. kreisbogenförmig ausgebildet.Apart from a structural relief and greater pressure stability of the entire boiler construction, the combustion chamber, the partition, the receiving housing, and ultimately also the return manifold in horizontal section or in plan view are preferably also circular or circular arc-shaped in consideration of a uniform distribution.
Ferner ist der die Heizgase zum Abgasanschluß abführende, parallel zur Brennkammer angeordnete Wärmetauscher in einer wasserführenden Erweiterung des Gehäuses angeordnet und steht dabei zuströmseitig mit dem oberen Teil der Brennkammer in Verbindung, wobei im die Abgase in Heizgaszugrohren führenden Wärmetauscher die Heizgaszugrohre im Sinne der vorerwähnten
Ausgehend von diesen weiterbildenden Maßgaben ist der die Trennwand und die Strömungszonen aufnehmende wasserführende Innenraum des Gehäuses gegen die den Wärmetauscher enthaltende Erweiterung des Gehäuses bis auf vorlaufseitig angeordnete Überströmöffnungen durch Wände abgetrennt, und ferner ist der Rücklaufverteiler im Gehäuse über eine in der Erweiterung angeordnete Steigleitung und eine Verbindungsleitung mit dem an der Erweiterung angeordneten Rücklaufanschluß verbunden. Dadurch erfährt der durch den Rücklaufanschluß zuströmende Rücklauf vorteilhaft bereits in diesem Bereich eine gewisse Vorwärmung und gelangt so, schon etwas vorgewärmt, via Rücklaufverteiler in die äußere Strömungszone und erst danach in die innere Strömungszone und damit an die heiße Brennkammerwand.Based on these further education requirements of the dividing wall and the flow zones receiving water-bearing interior of the housing is separated from the heat exchanger containing extension of the housing up to flow side arranged overflow through walls, and further, the return manifold in the housing via a arranged in the extension riser and a Connecting line connected to the arranged on the extension return port. As a result, the return flow flowing in through the return connection advantageously already achieves a certain degree of preheating in this area and thus, already somewhat preheated, via return distributor into the outer flow zone and only then into the inner flow zone and thus to the hot combustion chamber wall.
Abzugsseitig ist außerdem in Weiterbildung und im Gegensatz zum Gegenstand gemäß der
Der erfindungsgemäße Festbrennstoffheizkessel sowie dessen vorteilhaften Ausführungsformen gemäß der abhängigen Patentansprüche werden anhand der zeichnerischen Darstellung von Ausführungsbeispielen nachfolgend näher erläutert.The solid fuel boiler according to the invention and its advantageous embodiments according to the dependent claims are explained in more detail below with reference to the drawing of exemplary embodiments.
