Abstract
Description
Die derzeitigen Heizkessal für Öl- und Gasfeuerung als Niedertemperaturkessal müssen aus hochwertigen Materialien hergestellt werden und dürfen innerhalb des Kessels keine Taupunktkorrosion bekommen, da die bisherigen Materialien diese Taupunktkorrosion nicht aushalten.The current heating boiler for oil and Gas firing as a low-temperature boiler must be switched off high quality materials are manufactured and are not allowed inside the boiler Get dew point corrosion since the previous ones Materials do not have this dew point corrosion withstand.
Es wird daher versucht, durch schnelle Temperaturerhöhungen den natürlich im Heizkessel beim Anfahren entstehenden Taupunkt schnell zu überschreiten, so daß die kurze Taupunkterscheinung wieder anschließend abgetrocknet wird.It is therefore tried by quick Temperature increases naturally in the boiler dew point arising when moving off exceed so that the short Dew point appearance again afterwards is dried.
Ebenfalls müssen starke Isoliermaterialien verwendet werden, damit nur geringe Wärmeabstrahlung an den Raum erfolgt. Diese Probleme wurden von uns erfindungsgemäß dadurch gelöst, daß wir Flüssigkeiten als Wärmeträger verwenden und die Materialien nur von der Flüssigkeit umgeben sind. Es können dadurch sehr preisgünstige und korrosionssichere Materialien, wie Kunststoff verwendet werden. Damit Isolierungen eingespart werden können, ist der Wärmestrom einschließlich der Wärmerückgewinnung so angeordnet worden, daß die kalte, vom Freien geholte Frischluft, im äußersten Ring sich nach unten bewegt und gleichzeitig von den heißen Abgasen aufgeheizt werden. Es konnte daher erfindungsgemäß erreicht werden, daß keine äußere Isolierung notwendig ist und trotzdem kaum eine Wärmeabgabe an den Raum erfolgen kann. Die noch kalte Außenluft wird von dem warmen Abgas erwärmt und muß nicht vom Öl- oder Gasbrenner vorgewärmt werden. Gleichzeitig entsteht die Taupunktkorrosion innerhalb des Abgasbereiches. Strong insulation materials must also be used be used so that only minor Heat is radiated to the room. These According to the invention, this caused us problems solved that we have liquids as heat carriers use and the materials only from the Liquid are surrounded. This can make it very inexpensive and corrosion-proof materials, how plastic is used. In order to Insulations can be saved is the Heat flow including heat recovery arranged so that the cold, from the outdoors fetched fresh air, in the outermost ring moved down and at the same time by the hot ones Exhaust gases are heated. So it could can be achieved according to the invention that no external Isolation is necessary and yet hardly any Heat can be given off to the room. The still cold outside air is heated by the warm exhaust gas and does not need to be preheated by the oil or gas burner will. At the same time, the Dew point corrosion within the exhaust area.
Die naturgemäß hierdurch entstehende schwefelige Säure und Wasser wird automatisch nach unten in den Flüssigkeitskreislauf gegeben. Die verwendeten Materialien wie z. Bsp. Kunststoff sind säurefest. Die in den Gasführungen angebrachten Ringe dienen zur Verstärkung der Materialien und gleichzeitig als Umlenkung der Abgase, so daß an den Engstellen jeweils eine höhere Geschwindigkeit und dadurch auch ein höherer Wärmeübergang des Materiales erfolgt. Der Wärmetauscher für die Wärmeentnahme ist durch die Rohr-in-Rohr-Anordnung erfindungsgemäß so angeordnet, daß an der Außenwand eine hohe Wassergeschwindigkeit entstehen kann und dadurch auch bei Kunststoffen ein relativ hoher Wärmeübergang entsteht. Durch die ringförmigen Verstärkungen kann dieses Rohr auch eine höhere Druckbelastung bekommen und dadurch erfindungsgemäß in der Praxis mit 2,5 bar oder höher für den Wärmeaustausch angewendet werden. Die Anordnung wurde erfindungsgemäß so vorgenommen, daß insgesamt drei Behälter mit den Verstärkungsringen und gleichzeitigen Engstellen ineinandergeschoben ist und der Ring (2) gleichzeitig durch das Eintauchen in die Flüssigkeit als Trennung zwischen Abgas und Frischluft dient. Bei ausgezogenem Behälter können sämtliche Umlenkungen leicht geprüft und gereinigt werden.The resulting sulfurous acid and water are automatically added down into the liquid circuit. The materials used such. For example, plastics are acid-resistant. The rings attached in the gas ducts serve to reinforce the materials and at the same time to deflect the exhaust gases, so that a higher speed and thereby a higher heat transfer of the material takes place at the narrow points. The heat exchanger for the heat removal is arranged by the tube-in-tube arrangement according to the invention so that a high water velocity can occur on the outer wall and thus a relatively high heat transfer also occurs with plastics. Due to the annular reinforcements, this tube can also be subjected to a higher pressure load and can therefore be used according to the invention in practice at 2.5 bar or higher for the heat exchange. The arrangement was made according to the invention so that a total of three containers with the reinforcing rings and simultaneous constrictions are pushed into one another and the ring ( 2 ) simultaneously serves as a separation between exhaust gas and fresh air by immersion in the liquid. With the container pulled out, all deflections can be easily checked and cleaned.
