Abstract

Near their entry into a chimney, hot combustion fumes rising from a central heating boiler furnace (1) are injected from a nozzle (4) with a fine aerosol spray of water. Through travelling in the same direction, the water particles have considerable time to absorb heat from the fumes. The water mist condenses on the chimney wall and also on the branches of a bush-like insert (8). Condensate descends to a collector (10) below the furnace; and from the condensate pool a submerged heat exchanger recovers useful heat. USE - For domestic heating plant.

Description

Die Abgase aus dem Feuerungsraum 1 werden durch das Abgasrohr 2 in den Kamin 3 eingeleitet.The exhaust gases from the combustion chamber 1 are introduced into the chimney 3 through the exhaust pipe 2 .

Der Zerstäuber 4 vermischt die Abgase auf der Strecke 1 a, 2 a und 3 a mit Aerosol-förmigem Kaltwassernebel. Hierdurch wird die Abgastemperatur auf der Strecke 2 a und 3 a bis zum Taupunkt herabgesetzt. Die erwärmten Wasserteilchen sammeln sich an der Wandung des Abgasrohres 2 und an der Wandung des Kamins 3. Der beispielsweise bürstenförmig angenommene Abscheider 8 erfaßt die im Kernstrom der Abgase mitgeführten Wasserteilchen und leitet diese zusammen mit den bereits ausgeschiedenen Wasserteilchen über die Abgasrohrsohle des Abgasrohres 2 zu dem Behälter 10 des Wärmetauschers 7.The atomizer 4 mixes the exhaust gases on the route 1 a , 2 a and 3 a with aerosol-shaped cold water mist. As a result, the exhaust gas temperature on the route 2 a and 3 a is reduced to the dew point. The heated water particles collect on the wall of the exhaust pipe 2 and on the wall of the chimney 3 . The, for example, brush-shaped separator 8 detects the water particles carried in the core flow of the exhaust gases and passes them together with the water particles which have already been eliminated via the exhaust pipe base of the exhaust pipe 2 to the container 10 of the heat exchanger 7 .

Auf der Strecke 1 a bis 3 a wird dem Abgas die Verdampfungs­ wärme entzogen. Durch Nachdosierung mit Kaltwassernebel auf der Strecke 3 b wird der Kaltdampf, bereits kondensierter aber noch nicht ausgeschiedener Wasserdampf, ausgeschieden. On the route 1 a to 3 a , the evaporation heat is extracted from the exhaust gas. The cold vapor already condensed but not yet precipitated water vapor is b by topping up with cold water mist on the track 3, resigned.

KurzbeschreibungBrief description

Die heißen Abgase werden innerhalb des Kessels mit aerosolförmigem Kaltwasserdampf vermischt. Beschleunigungsrichtung des Kalt­ wasserdampfes ist gleich mit der Zugrichtung der Abgase. Der Kaltwasserdampf nimmt die Wärme der Abgase auf und schlägt sich an der Abgasrohr- und Kaminwandung nieder. Auf der Sohle des Abgasrohres fließt das erwärmte Wasser zu dem Auffangbehälter mit Wärmetauscher.The hot exhaust gases are inside the Boiler with aerosol-shaped cold water vapor mixed. Direction of acceleration of the cold water vapor is equal to the direction of pull the exhaust gases. The cold water vapor takes that Heat the exhaust gases and hits the Exhaust pipe and chimney wall down. On the The heated water flows through the bottom of the exhaust pipe to the collecting tank with heat exchanger.

Stand der TechnikState of the art

Vergleichbare Naßreinigungsverfahren sind im industriellen Bereich üblich, jedoch ist der erforderliche Maschinenpark im häuslichen Be­ reich nicht einsetzbar und ungeeignet für die Wärmerückgewinnung.Comparable wet cleaning processes are in the industrial area is common, however the required machinery in the home not usable and unsuitable for the Heat recovery.

Bei im häuslichen Bereich eingesetzten Abgaswä­ schern werden Wassertropfen/Strahlen gegenläufig durch den Abgasstrom geschickt. Nachteile: Die hohe Relativbewegung zwischen Abgasstrom und eingesprühten Wassertropfen erlaubt keinen schnellen Wärmeübergang.With exhaust gas scrubbers used in the home shear water drops / jets in opposite directions sent through the exhaust stream. Disadvantage: The high relative movement between exhaust gas flow and sprayed water drops do not allow rapid heat transfer.

Durch die verhältnismäßig große, umzuwälzende Wassermenge im Verhältnis zum Wärmegewinn, ist der Wärmefluß zum Verbraucher zu träge oder liegt nicht im nutzbaren Bereich.Due to the relatively large, revolutionary Amount of water in relation to the gain in heat the heat flow to the consumer is too slow or is not in the usable range.

Der maschinelle und installationstechnische Aufwand ist hoch.The mechanical and installation technology Effort is high.
