Abstract

The heat exchanger is used for heat recovery from flue gases of central heating system. The recovered energy is used additionally for water heating. The heating return water is not returned directly into boiler but through a heat exchanger. The high return flow temp. ensures that the temperatures will not readily fall below the dew point. The heat exchanger has enclosing pipe accommodating straight pipe cluster. The helical heat exchanger has one helical pipe. Straight and helical pipes may be used as alternatives.

Description

Pekuperative '.Värmegewinnung aus den Rauchgasen von HeizungskesselPekuperative 'heat recovery from the flue gases of heating boilers

Mit diesen Konstruktionen soll eine verbesserte Primärenergieausnutzung in Zentralheizungsanlagen erzielt werden.These constructions are intended to improve the utilization of primary energy can be achieved in central heating systems.

Durch den Einbau des Wärmeaustauschers gelingt es, die Rauchgaseintrittstemperatur in den Schornstein herabzusetzen und die dabei frei werdende Energie an das umlaufende Heizungswasser zu übertragen.By installing the heat exchanger, it is possible to control the flue gas inlet temperature in the chimney and the energy released in the process to the circulating Transfer heating water.

In vielen bestehenden Heizungsanlagen liegen die Rauchgaseintrittstemreraturen am Schornstein weit über dem physikalisch ertorderlichen Level. Durch den eingebauten Wärmetauscher können die unnötigen Energieverluste vermieden werden. Aus den Prinzipsskizzen lässt sich der apparative Aufwand und das Funktionsschema ablesen. Das Heizungsrücklaufwasser wird nicht wie bisher direkt in den Heizungskessel zurückgeführt, sondern zunächst über den Wärmetauscher geleitet.The flue gas inlet temperatures are in many existing heating systems at the chimney far above the physically required level. Through the built-in Heat exchangers can avoid unnecessary energy losses. From the principle sketches the expenditure on equipment and the functional diagram can be read off. The heating return water is not fed back directly into the boiler as before, but initially passed through the heat exchanger.

Diese Wärmerückgevinnung hat ausserdem den Vorteil, dass durch die erhöhte Rüclrlauftemperatur einer Taupunkttemperaturunterschreitung noch intensiver entgegengewirkt wird.This heat recovery also has the advantage that through the increased return temperature if the temperature falls below the dew point even more intensively is counteracted.

Der Wärmetauscher besteht aus einem Mantelruhr 300 mm Din 2440 und einem darin bcfindlichen geraden Rohrbündel. Die Anzahl der Pauchgasrohre kann den individuellen Erfordernissen angepasst werden.The heat exchanger consists of a jacket tube 300 mm Din 2440 and a straight tube bundle located therein. The number of Pauchgasrohre can den can be adapted to individual requirements.

( Figur 1 ).(Figure 1).

Der Spiralenwärmetauscher besteht aus einem 300 mm Rauchrohr und aus einem Spiralenrohr Din 241wo. Alles weitere wie Figur IC ( Figur In ).The spiral heat exchanger consists of a 300 mm smoke tube and a spiral tube Din 241wo. Everything else like figure IC (figure In).

Claims (1)

Patentansprüche: Die Patentansprüche beziehen sich sowohl auf das System der rekuperativen Wärmerückgewinnung aus den Rauchgasen von zentralen Heizungsanlagen als auch auf die aus den Skizzen entnehmbare Konstruktion.Claims: The claims relate to both System of recuperative heat recovery from the flue gases from central heating systems as well as the construction that can be taken from the sketches.
