Abstract

The chimney is esp. for use where smoke temps. are lowered below condensation point in follow-up heat-exchangers. The brick structure of the chimney contains a tube made of rust-free steel. This is pref. carried into the heat-exchanger utilising smoke heat, at least to the verge of the condensation point. The heat-exchanger pipe system carrying smoke away may be made of rust-free steel. This makes it practicable to exploit the difference in temp. between smoke and the environment, for heating purposes.

Description

Beschreibung SchornsteinDescription chimney

Hauskamine sind normalerweise aus Stein mit Isolierschicht oder ohne Isolierschicht. Will man nun die Rauchgaswärme der Heizung weiter nutzen, so besteht die Gefahr der Kaminversottung. Insbesondere der Schwefelgehalt des Heizmaterials ist für den Schornstein problematisch. Ein 0,5 % Schwefelgehalt setzt den Taupunkt schon auf 130 ° C hinauf.Home fireplaces are usually made of stone with or without an insulating layer Insulating layer. If you want to continue to use the flue gas heat from the heating system, there is the risk of chimney sooting. In particular, the sulfur content of the heating material is problematic for the chimney. A 0.5% sulfur content sets the dew point already up to 130 ° C.

Unterhalb dieser Temperatur bildet sich mit dem Wasserdampf der Rauchgase H2 SO . Aus dssem Grunde ist es nicht möglich, die Gempeßaturdifferenz zwischen der Rauchgas- und Umgebungstemperatur zu Heizzwecken zu verwenden. Der Erfinder hat es sich zur Aufgabe gemacht, diesen Nachteil zu beseitigen.Below this temperature, the smoke gases form with the water vapor H2 SO. For this reason it is not possible to determine the temperature difference between the flue gas and ambient temperature for heating purposes. The inventor has set itself the task of eliminating this disadvantage.

Er schlägt vor,den Kamin mit einem schwefelsäureresistenten ttterial auszukleiden, daß ebenfalls erhöhte Rauchgastemperaturen verträgt. Es könnte sein, daß der dem Ofen nachgeschaltete Warmetauscher undicht wird. So würde die Rauchgastemperatur wieder steigen und im Schornstein entsprechenden Schaden anrichten oder sogar einen Brand auslösen. Der Erfinder schlägt vor, ein Rohr aus nichtrostendem Stahl z. B. V4A, d etwas kleiner ist als die Schornsteinöffnung, von oben in die Schornsteinöffnung einzulassen. Das Rohr des Wärmetauschers, daß äa nichts anderes ist als ein verlängerter Schornstein, soll ab der Strecke auf der die Absenkung der Temperatur unter dem Taupunkt beginnt, ebenfalls aus rostfreiem Stahl wie V2A oder V4A usw. bestehen.He suggests using a sulfuric acid-resistant ttterial in the fireplace to be lined that also tolerates increased flue gas temperatures. It could be, that the heat exchanger downstream of the furnace is leaking. So would the flue gas temperature rise again and cause damage to the chimney, or even one Start a fire. The inventor proposes a pipe made of stainless steel z. B. V4A, d is slightly smaller than the chimney opening, into the chimney opening from above to let in. The tube of the heat exchanger that aa is nothing other than an elongated one Chimney, should start from the route on which the lowering of the temperature below the Dew point begins, also made of stainless steel such as V2A or V4A etc.

Abb. 1 zeigt eine Heizungsanlage. Vom Kessel (1) fließen die Rauchgase über den Rauchgasfuchs (2) in den Wärmetauscher (3). Diesen verlassen die heruntergekühlten Rauchgase über die Verbindung (4) in den Schornstein (5). Die Auskleidung mit nichtrostendem Stahl verhindert die Durchsottung.Fig. 1 shows a heating system. The flue gases flow from the boiler (1) via the flue gas duct (2) into the heat exchanger (3). The chilled ones leave this Flue gases through the connection (4) into the chimney (5). The lining with stainless Steel prevents soaking through.

Dieses Rohr kann bis zum Kessel durch den Wärmetauscher gefiltert werden. So ist die Korrosion, Verrottung des Mauerwerkes vermieden und die Rauchgaswärme kann über den Wärmetauscher genutzt werden. Zu dem kann ein Absaugen der Wärme durch den Schornstein bei Brennerstillstand vermieden werden.This pipe can be filtered through the heat exchanger up to the boiler will. This avoids corrosion, rotting of the masonry and the flue gas heat can be used via the heat exchanger. The heat can also be extracted by suction the chimney can be avoided when the burner is at a standstill.
