A central heating boiler has a combustion chamber (1) and situated below it an afterheating region (2) of vertical ceramic pipes (7) running from an upper to a lower ceramic plate (6,8). <IMAGE>

Description

Zentralheizungskessel Central heating boiler

sie Erfindung betrifft einen Zentralheizungskessel nach dem Oberbegriff des Patentanspruches 1 wie er beispielsweise der DE-OS 28 37 004 oder der nicht vorveröffentlichten deutschen Patentanmeldung P 33 02 477.4 zu entnehmen ist.the invention relates to a central heating boiler according to the preamble of claim 1 such as DE-OS 28 37 004 or not pre-published German patent application P 33 02 477.4 can be found.

Bei einem solchen Heizungskessel werden die Heizgase im Heizgas zug abwnrts geführt und infolge einer ausreichend großen Wärmeaustauschfläche bis unter den Taupunkt abgekühlt. Es scheidet sich Kondensat aus, welches sich in einem Sammelraum unterhalb des Heizgaszuges aufgefangen und von dort abgeführt wird. Die abgekühlten, trockenen Heizgase strömen zum Schornstein weiter.In such a heating boiler, the heating gases in the heating gas are train downwards and as a result of a sufficiently large heat exchange surface to below cooled down the dew point. It separates out condensate, which is in a collecting space is collected below the heating gas flue and discharged from there. The cooled, dry heating gases continue to flow to the chimney.

Ein solcher Heizungskessel, auch Brennwertkessel genannt, hat den Vorteil einer äußerst hohen Energieausbeute. Während bei herkömmlichen Heizungskesseln Heizgastemperaturen um 180 0 am Kesselausgang nicht unterschritten werden sollten, um eine Versottung des Schornsteines zu vermeiden, können die Temperaturen im Heizungskessel jetzt auf Werte um 40 OC abgesenkt werden.Such a heating boiler, also called a condensing boiler, has the Advantage of an extremely high energy yield. While with conventional heating boilers Heating gas temperatures should not fall below 180 0 at the boiler outlet, to avoid sooting the chimney, the temperatures in the boiler can now be lowered to values around 40 OC.

Die durch die Temperaturabsenkung frei werdende Wärme und die Kondensationswärme können zusätzlich vom Heizwasser übernommen werden. Dadurch steigt der Tirkung5grad beträchtlich.The heat released by the drop in temperature and the heat of condensation can also be taken over by the heating water. This increases the degree of efficiency considerably.

Ein Problem bei den Heizungskesseln der genannten Art entsteht durch die starke Korrosionswirkung des ausgeschiedenen Kondensats. Insbesondere der Heizgaszug ist den Angriffen des sauren Kondensats beständig ausgesetzt. Um Zerstörungen des Heizungskessels zu vermeiden, ist es üblich, die gefährdeten Wärmeaustauschflächen mit einer Schutzschicht etwa auf der Basis des Emails zu versehen. Es wurde auch schon versucht, diese Flächen aus korrosionsfestem Werkstoff herzustellen. Dabei ist der Einsatz von Edelstahl, vorallem aber von keramischen Werkstoffenedenkbar.A problem with the boilers of the type mentioned arises from the strong corrosive effect of the precipitated condensate. In particular, the heating gas flue is the attacks of the Resistantly exposed to acid condensate. Around To avoid destruction of the heating boiler, it is common to use the endangered heat exchange surfaces to be provided with a protective layer, for example on the basis of the enamel. It was too already tried to produce these surfaces from corrosion-resistant material. Included the use of stainless steel, but above all of ceramic materials, is conceivable.

Es soll ein Heizungskessel geschaffen werden, bei dem der Heizgaszug aus keramischen Werkstoffen gebildet ist, um den Belastungen durch das entstehende Kondensat zu widerstehen.A heating boiler is to be created in which the heating gas flue is made of ceramic materials to withstand the stresses generated by the Resist condensate.

Gemäß der Erfindung wird dieses bei einem Heizungskessel mit den im Kennzeichen des Patentanspruches 1 genannten Merkmalen erreicht.According to the invention, this is in a boiler with the im Characteristics of claim 1 mentioned features achieved.

Der besonders gefährdete hintere Bereich des Heizungskessels ist vollständig aus Keramik aufgebaut. Die Keramikplatten lassen sich einwandfrei in einem äußeren Metallgehäuse abdichten.The particularly endangered rear area of the boiler is complete made of ceramic. The ceramic plates can be flawlessly in an outer Seal the metal housing.

Durch ein direktes Einfügen der Keramikrohre in die Keramikplatten sind im Ubergangsbereich keinerlei korrosionsgefährdete Metallteile vorhanden. Zum anderen ist ein Minimaleinsatz an keramischem Werkstoff gegeben, der zu einer preisgünstigen und einfachen Herstellung des Heizgaszuges führt. Ein besonderer Vorteil besteht darin, daß je nach den Verhältnissen unterschiedlich lange Rohre zur Erzeugung von unterschiedlich langen Heizgaszügen verwandt werden können. Man ist dadurch sehr flexibel bezüglich einer Anpassung des Heizgaszuges an den erwünschten Wärme abbau.By inserting the ceramic tubes directly into the ceramic plates There are no metal parts at risk of corrosion in the transition area. To the Others are given a minimal use of ceramic material, which leads to an inexpensive one and simple production of the Heizgaszug leads. There is a particular advantage in that, depending on the circumstances, pipes of different lengths for the production of hot gas flues of different lengths can be used. It makes you very much flexible in terms of adapting the hot gas flue to the desired heat dissipation.

Die beigefügte Zeichnung stellt in einer einzigen Figur ein Ausführungsbeispiel der Erfindung als Längsschnitt durch einen Heizungskessel dar.The attached drawing shows an exemplary embodiment in a single figure of the invention as a longitudinal section through a heating boiler.

Der Heizungskessel besteht aus einer Brennkammer 1 und einem Nachschaltbereich 2. Oberhalb der Brennkammer 1 sitzt auf einer isolierten Brennertür 3 ein Sturzbrenner 4. Ein Umlenkschirm 5 aus schlecht wärmeleitendem Material sorgt für eine Umlenkung der Brennerflamme und für eine Abschirmung des Heizgaszuges gegen direkte Heizgasstrahlung.The heating boiler consists of a combustion chamber 1 and a downstream area 2. Above the combustion chamber 1 there is a lintel burner on an insulated burner door 3 4. A deflecting screen 5 made of poorly thermally conductive material ensures deflection the burner flame and for shielding the heating gas flue against direct heating gas radiation.

Die Brennkammer 1 wird durch eine Keramikplatte 6 begrenzt.The combustion chamber 1 is delimited by a ceramic plate 6.

Von dieser führen Keramikrohre 7 zu einer in Abstand angeordneten weiteren Keramikplatte 8, welche die obere Begrenzung eines Sammlers 9 aus korrosionsbeständigem Material bildet.Ceramic tubes 7 lead from this to a spaced-apart one further ceramic plate 8, which is the upper limit of a collector 9 made of corrosion-resistant Material forms.

Vom Sammler 9 gelangt das ausgeschiedene Kondensat durch einen Syphon 10 zu Ablauf, während die trockenen Heizgase durch einen Abgasstutzen 11 zu Schornstein strömen.The separated condensate passes from the collector 9 through a siphon 10 to the drain, while the dry heating gases through an exhaust nozzle 11 to the chimney stream.

Das Wasser mündet durch den Rücklauf 12 in den unteren Bereich des Heizungskessels. Es durchströmt diesen im Gegenstrom zu den Heizgasen5um durch den Vorlauf 13 wieder in Heizungsnetz zu gelangen.The water flows through the return 12 into the lower area of the Heating boilers. It flows through this in countercurrent to the heating gases 5um through the Flow 13 to get back into the heating network.
