Abstract

With this invention, the heating boiler becomes, as a result of the installation of a large-volume copper pipe coil which is closely packed and if possible has an oval cross-section, an ideal flow heater for service water, as a result of which a separate service-water boiler is no longer necessary. The advantage of this heating boiler embodiment can be seen in that 1. only one heating boiler is necessary without an additional service-water boiler, 2. a large-volume water-bearing heating-water housing which additionally serves as a heat accumulator, 3. has a large-volume approximately oval copper heating coil which stores a large hot-water supply and is constantly immersed in the hot heating water, 4. as a result of this arrangement of the large-volume service water copper-pipe heating coil in the hot heating water, sufficiently hot service water is made possible every 10 minutes for a full bath or uninterrupted hot showering, 5. as a result of the installation of a large steel catalytic converter which is open in the central part, the toxic CO and other harmful substances of the flue gas are converted into non-toxic waste gases by a lambda probe, 6. this steel catalytic converter which is open in the central part simultaneously serves, as a result of its great heat resistance (1500@C), as heating element of the boiler combustion chamber and, incandescent, also combusts the oil particles which are difficult to combust of the heating oil in the 3-pass heating method, as a result of which rapid heating of the heating water and of the service water is achieved.

Description

Die Erfindung betrifft einen Heizungskessel mit Durchlaufer hitzer gemäß Oberbegriff des Patentanspruches 1.The invention relates to a boiler with a flow Heater according to the preamble of claim 1.

Bei diesem Heizungskessel 1 ist das heizungswasserführende Gehäuse etwa doppelt so groß wie bei den derzeitig im Handel befindlichen Heizungskesseln.In this heating boiler 1 , the heating water-carrying housing is approximately twice as large as in the heating boilers currently on the market.

In diesem Heizungswasser-Gehäuse 1 und 2 ist eine großvo lumige, etwa oval geformte Kupferrohrwendel 3 angeordnet, welche zirka 30-40 ltr. Brauchwasser aufweist, das durch das gut wärmeleitende Kupferrohr sehr schnell die Heizwärme des Heizungswassers aufnimmt. Der Heizungswasserfühler 4 für den Thermostat des Heizölbrenners 5 ist an der tempera turempfindlichsten Stelle des Heizungswasserbehälters 1 vorgesehen, so daß der Heizbrenner 5 schon wenige Sekunden nach Brauchwasserentnahme sich einschaltet und das Heizungs wasser auf etwa +70° Cels konstant warmhält, so daß auch bei großem Brauchwasserverbrauch der Wärmewert desselben auch bei Dauerverbrauch nicht unter +50° Cels abfällt.In this heating water housing 1 and 2 is a Großvo lumige, approximately oval shaped copper tube coil 3 is arranged, which approximately 30-40 ltr. Has hot water, which absorbs the heating heat of the heating water very quickly thanks to the good heat-conducting copper pipe. The heating water sensor 4 for the thermostat of the heating oil burner 5 is provided at the most temperature-sensitive point of the heating water tank 1 , so that the heating burner 5 switches on just a few seconds after hot water is drawn and the heating water keeps warm at about + 70 ° Cels, so that even with large Hot water consumption, the heat value of the same does not drop below + 50 ° Cels even with continuous consumption.

Eine gute Heizkessel-Isolierung 6 nach dem neuesten Stand der Technik verhindert Wärmeverluste im Heizungskeller, so wie die Schaltgeräusche des Heizbrenners.Good, state-of-the-art boiler insulation 6 prevents heat loss in the boiler room, as does the switching noise of the burner.

Um das giftige Monoxid und die anderen Schadstoffe der Heiz kesselabgase zu absorbieren, sind mehrere Katalysatoren 9 angeordnet, welche in Verbindung mit einer Lambda-Sonde 1 durch ein chemisches Verfahren die Schadstoffe in ungiftige Gase umwandelt.In order to absorb the toxic monoxide and the other pollutants of the boiler exhaust gases, several catalysts 9 are arranged, which in conjunction with a lambda probe 1 converts the pollutants into non-toxic gases by a chemical process.

Hinter den Katalysatoren 10 und 16 ist ein größerer Kessel- Freiraum vorgesehen, welche als Abgasverteiler dient.A larger boiler space is provided behind the catalysts 10 and 16 , which serves as an exhaust gas distributor.

Hinter diesem Kesselfreiraum sind die Gußstahl-Wärmespeicher 1 angeordnet, welche durch eine lange Schraube mit Ringöse 17 fest miteinander verbunden sind. Durch diese Maßnahme ist ein leichtes Herausnehmen dieses Wärmespeicherpaketes ge währleistet. Behind this boiler space, the cast steel heat accumulator 1 are arranged, which are firmly connected to one another by a long screw with a ring eyelet 17 . This measure ensures easy removal of this heat storage package.

Die Katalysatoren dienen außer der Schadstoffreinigung gleichzeitig als schnell erhitzbare Heizelemente, welche durch ihr hochwertiges Folien-Stahl-Material, in wenigen Sekunden weißglühend, ihre Heizwärme direkt an den Brauch wasserkessel abgeben, wodurch eine ganz schnelle Erwärmung des Heizungs- und Brauchwassers erreicht wird.The catalysts are used in addition to pollutant cleaning at the same time as quickly heatable heating elements, which due to their high-quality foil-steel material, in a few Incandescent seconds, their heating heat directly to the custom dispense water boiler, which causes a very quick heating of the heating and process water is reached.

Auf eine Länge von etwa 45 cm ist der Heizraum weißglühend, wobei die Heizkatalysatoren selbst eine Hitzebelastung von 1500° Cels ohne Bedenken überstehen.The boiler room is incandescent over a length of about 45 cm, the heating catalysts themselves have a heat load of Withstand 1500 ° Cels without hesitation.

Katalysatoren für Heizungskessel weisen eine besondere Aus führungsform auf, denn der bewährte 3-Zug-Heizkessel gewähr leistet die restlose Verbrennung auch der schwer brennbaren Heizölteilchen. Dieser Heizungsvorgang wäre mit den für Ex plosionsmotoren entwickelten Katalysatoren nicht erreichbar, da mit diesen nur ein Einweg-Heizvorgang durchführbar ist. Aus dieser Erkenntnis, welche durch zahlreiche Versuche und Heizungstests erwiesen ist, kann nur der Hohlraum- Katalysator für Kesselheizungszwecke in Frage kommen.Catalysts for heating boilers have a special feature form, because the proven 3-pass boiler guarantees performs the complete combustion even of the flame-resistant Fuel oil particles. This heating process would be the same as for Ex plosion motors developed catalysts not available, since only a one-way heating process can be carried out with these. From this knowledge, which through numerous attempts and heating tests, only the cavity Catalyst for boiler heating purposes.
