Abstract

System for flue gas recovery, in which the coolant for the flue gas cooling is conveyed from a buffer storage tank, in which the heater water in the buffer storage tank serves as the coolant, and cooling is effected from the liquid channel (3+4) via the ducts and water heater for use (11), and the duct system and also both channels (3+4) with the ducts (1+2) can be cooled in the buffer storage tank. <IMAGE>

Description

System zur AbgasrückgewinnungSystem for exhaust gas recovery

Die Erfindung bezieht sich auf ein System zur Abgaswärmerückgewinnung entsprechend dem Oberbegriff des Anspruch 1.The invention relates to a system for exhaust gas heat recovery according to the preamble of claim 1.

Bekannt ist bisher eine Abgaswärmerückgewinnung, in dem hauptsächlich der Heizungsrücklauf über einen Wärmetauscher die Abgase entsprechend der Temperatur des Heizungsrücklaufes abgekühlt hat. Dadurch konnte in den wenigsten Fällen das Abgas unter dem Taupunkt abgekühlt werden.So far, an exhaust gas heat recovery is known, in which mainly the heating return via a heat exchanger the exhaust gases according to the temperature of the heating return has cooled down. As a result, in very few cases Exhaust gas can be cooled below the dew point.

Erfindungsgemäß wurde dieser Nachteil gelöst, in dem das Kühlmedium für die Abgasabkühlung aus einem Pufferspeicher gefördert wird. Der Wasserinhal t des Pufferspeichers wird entsprechend der Heizkessel leitung ausgelegt. Der zweite Kreislauf ist an dem Gebrauchswasserbereiter angeschlossen, in dem das Gebrauchswasser direkt oder über einen gesonderten Kreislauf indirekt das Abgas abkühlt. Hierdurch läßt sich besonders preisgünstig und wartungsarm eine Dauerabkühlung der Rauchgase unter dem Taupunkt erreichen.According to the invention, this disadvantage was solved in that the cooling medium for the exhaust gas cooling is promoted from a buffer storage. The water content t of the buffer tank is designed according to the boiler line. The second Circuit is connected to the utility water heater in which the utility water directly or indirectly via a separate circuit cools the exhaust gas. Through this a permanent cooling of the flue gases can be carried out particularly inexpensively and with little maintenance reach below the dew point.

Das Merkmal des Anspruchs (2) zeigt die verschiedenen ,öglichkeiten und Lage des Pufferspeichers.The feature of claim (2) shows the different options and location of the buffer storage.

Das Merkmal des Anspruchs (3) zeigt die Anordnung der VÇarmluftansaugung zur Kaminaustrocknung.The feature of claim (3) shows the arrangement of the VÇarmluftansaugung for chimney drying.

Durch das Merkmal des Ansprchs (4) wird erreicht, daß über eine kleine Wärmepumpe System Wasser - Wasser Ni edertemperatur-Wärme aus dem Pufferspeicher mit einer entsprechenden höheren Temperatur in den Heizkessel transportiert wird.By the feature of claim (4) it is achieved that over a small Heat pump system water - water Lower temperature heat from the buffer storage is transported into the boiler at a correspondingly higher temperature.

Das Merkmal des Anspruchs (5) zeigt, wie über den Kaltwasserzulauf des Gebrauchswarmwasserbereiters der Pufferspeicher auf niedere Temperaturen gehalten wird.The feature of claim (5) shows how about the cold water inlet of the domestic water heater, the buffer storage tank is kept at low temperatures will.
