Description
Die Erfindung betrifft eine Brennkammer für Warmwasserbereiter, insbesondere Gasheizgeräte, die eine die Brennkammer wenigstens seitlich begrenzende Brennkammerwand aus temperaturfestem Material aufweist.The invention relates to a combustion chamber for water heaters, especially gas heaters, the one that Combustion chamber at least laterally delimiting combustion chamber wall made of temperature-resistant material.
Eine solche Brennkammer ist z.B. aus DE 30 24 792 C2 bekannt.Such a combustion chamber is e.g. from DE 30 24 792 C2 known.
Für die Brennkammerwand bekannter Brennkammern werden zur Wärmedämmung zumeist aus Keramikfasern bestehende Platten verwendet, deren Wandstärke etwa 10 mm beträgt und die zur Stabilisierung mit einer Blechummantelung versehen sind.Known combustion chambers are used for the combustion chamber wall Thermal insulation mostly made of ceramic fibers used, the wall thickness is about 10 mm and for Stabilization are provided with a sheet metal jacket.
Die für die Brennkammerwand verwendeten Keramikfaser-Wärmedämmplatten stellen zwar eine kostengünstige Lösung für die geforderte Wärmedämmung der Brennkammerwand dar, weisen jedoch ein biologisch und physiologisch bedenkliches Fasermaterial auf, das durch Öffnungen in der Blechummantelung nach außen treten und in die Lunge eines Lebewesens, insbesondere eines Menschen gelangen kann. Außerdem sind die mit der Fertigung der Brennkammer befaßten Personen sehr gesundheitsgefährdet.The ceramic fiber thermal insulation panels used for the combustion chamber wall provide an inexpensive solution for the required thermal insulation of the combustion chamber wall, however have a biologically and physiologically questionable Fiber material on through openings in the sheet metal jacket step out and into the lungs of a living being, especially of a human being. Also are the people involved in the manufacture of the combustion chamber very dangerous to health.
Weiterhin haben die verwendeten Keramikfaserplatten zwar eine hervorragende Wärmedämmung, jedoch eine schlechte Alterungs- und Temperaturbeständigkeit. Furthermore, the ceramic fiber plates used have excellent insulation, but poor Resistance to aging and temperature.
Angesichts des oben Gesagten ist es Aufgabe der Erfindung, eine gattungsgemäße Brennkammer so zu ermöglichen, daß keine physiologisch bedenkliche Emissionen mehr auftreten und gleichzeitig die Alterungs- und Temperaturbeständigkeit der Brennkammerwand erhöht ist.In view of the above, it is the object of the invention to enable a generic combustion chamber so that no physiologically questionable emissions occur and at the same time the aging and temperature resistance the combustion chamber wall is raised.
Erfindungsgemäß wird die obige Aufgabe dadurch gelöst, daß die Brennkammerwand eine aus wärmedämmendem keramischem Isoliermaterial bestehende äußere Wandplatte oder -schicht und eine davon getrennte innere Wandplatte aus hochtemperaturbeständiger Strukturkeramik aufweist, die die äußere Wandplatte zum Innenraum der Brennkammer abdeckt.According to the invention the above object is achieved in that the combustion chamber wall is made of heat-insulating ceramic Insulating material existing outer wall plate or layer and a separate inner wall plate made of high temperature resistant Structural ceramics that the covers outer wall plate to the interior of the combustion chamber.
Demnach ist es Kern dieser Erfindung, den bekannten Aufbau der Brennkammer durch eine dünnwandige Schicht oder Platte aus hochtemperaturbeständiger Strukturkeramik auf der Brennkammerwandinnenseite zu ergänzen, die zum einen eine hohe Temperaturbeständigkeit und hervorragende Wärmedämmeigenschaften hat und andererseits die nach außen anschließende Wärmedämmschicht oder -platte gegenüber dem Brennerinnenraum abdeckt.Accordingly, it is the essence of this invention, the known structure the combustion chamber through a thin-walled layer or plate made of high temperature resistant structural ceramics on the To supplement the inside of the combustion chamber wall, on the one hand high temperature resistance and excellent thermal insulation properties and on the other hand the outside Subsequent thermal insulation layer or plate opposite the Burner interior covers.
Da die innere Wandplatte aus hochtemperaturbeständiger Strukturkeramik die äußere Wandplatte zum Innenraum der Brennkammer kapselt, kann die äußere Wandschicht oder -platte aus einer Keramikfaserplatte bestehen, da nun keine Keramikfasern mehr in die Umgebungsluft gelangen können. Alternativ und bevorzugt ist die äußere Wandplatte jedoch in Form einer Preßplatte aus keramischer Schüttung gebildet, die auch bei der Fertigung keine physiologisch bedenklichen Fasern abgeben kann. Because the inner wall plate made of high temperature resistant Structural ceramics the outer wall plate to the interior of the Encapsulates the combustion chamber, the outer wall layer or -plate consist of a ceramic fiber plate, since now none Ceramic fibers can get more into the ambient air. However, the outer wall plate is alternative and preferred in the form of a press plate made of ceramic fill formed, which is not physiological even during manufacture can give off questionable fibers.
Damit die Brennkammerwand auch nach außen hin stabilisiert und geschützt ist, ist die äußere Wandschicht oder -platte zusätzlich auf ihrer Außenseite von einem Halteblechmantel ummantelt.So that the combustion chamber wall also stabilizes towards the outside and protected, is the outer wall layer or panel additionally on the outside of a retaining sheet jacket jacketed.
Die aus hochtemperaturbeständiger Strukturkeramik bestehende innere Wandplatte kann vorteilhafterweise relativ dünnwandig ausgeführt werden, so daß sich in wenigen Sekunden nach Brennerstart ein homogenes Temperaturspektrum verstärkt durch die räumliche Trennung zur eigentlichen Wärmeisolierplatte, d.h. der äußeren Wandplatte einstellt.The high-temperature-resistant structural ceramic inner wall plate can advantageously be relative run thin-walled, so that in a few A homogeneous temperature spectrum seconds after the burner starts reinforced by the spatial separation from the actual one Thermal insulation panel, i.e. the outer wall plate.
Die vorgeschlagene Stoffkombination zur Abdeckung der Keramikfaserplatte oder der aus keramischer Schüttung bestehenden Preßplatte durch hochtemperaturbeständige Strukturkeramik resultiert darin, daß die Wandstärke der Brennkammerwand deutlich geringer sein kann.The proposed combination of fabrics to cover the Ceramic fiberboard or that of ceramic fill existing press plate through high temperature resistant Structural ceramics result in the wall thickness of the Combustion chamber wall can be significantly lower.
Wenn, wie bevorzugt, die äußere Wärmedämmplatte oder -schicht aus keramischer Schüttung besteht, kann ein äußeres, die äußere Wandschicht oder -platte ummantelndes Halteblech unter Einhaltung eines Luftspalts zwischen sich und der äußeren Wandschicht oder -platte angebracht sein. Durch diesen Luftspalt kann kühle Umgebungsluft strömen, die in an der Unterseite der Brennkammerwand befindliche Öffnungen ein- und durch Ausströmöffnungen an ihrer Oberseite ausströmt.If, as preferred, the outer thermal insulation board or layer consisting of ceramic fill can be a outer, encasing the outer wall layer or plate Holding plate with an air gap between them and the outer wall layer or plate. Cool ambient air can flow through this air gap, the one located on the underside of the combustion chamber wall Openings in and out of their openings Top side flows out.
Als zusätzliche, die Wärmedämmeigenschaften der Brennkammerwand verbessernde Maßnahme, kann die Innenwandfläche der aus hochtemperaturbeständiger Strukturkeramik bestehenden inneren Wandplatte außerdem mit einer infrarotreflektierenden Schicht beschichtet sein. Diese infrarotreflektierende Schicht ist nur einige µm dick und kann entweder aus einem temperaturfesten Metall, einer temperaturfesten Metallegierung oder alternativ aus einem nach seinem Emissionsspektrum ausgewählten keramischen Material bestehen. Dieses keramische Material kann beispielsweise Aluminiumoxid, insbesondere Korund, sein.As an additional, the thermal insulation properties of the combustion chamber wall corrective measure, the inner wall surface of the made of high temperature resistant structural ceramics inner wall plate also with an infrared reflecting Layer be coated. This infrared reflective Layer is only a few µm thick and can either made of a temperature-resistant metal, a temperature-resistant Metal alloy or alternatively from one after his Emission spectrum selected ceramic material consist. This ceramic material can, for example Alumina, especially corundum.
Durch die Beschichtung werden Temperaturspitzen an der Innenseite der Brennkammerwand abgebaut. Eine gleichmäßige Temperaturverteilung ist die Folge. In der als selbsttragende Platte ausgebildeten inneren Wandplatte aus hochtemperaturbeständiger Strukturkeramik werden so durch Temperaturspitzen hervorgerufene thermische Spannungen und Schwundrisse abgebaut bzw. vermieden.The coating eliminates temperature peaks at the Dismantled inside the combustion chamber wall. An even one The result is temperature distribution. In the as self-supporting Plate trained inner wall plate high-temperature-resistant structural ceramics are thus Thermal peaks and thermal stresses Shrinkage cracks reduced or avoided.
