Description
Die vorliegende Erfindung bezieht sich auf ein 30 lung ist folgende:
Verfahren gemäß dem Oberbegriff des Hauptanspruchs. Je nach der vom Temperaturfühler 4 gemessenenThe present invention relates to a 30 ment is the following:
Method according to the preamble of the main claim. Depending on the measured by the temperature sensor 4
Aus der DE-GM 77 10 693 ist ein Kessel für eine Temperatur der Rauchgase resultiert eine bestimmte Zentralheizungsanlage bekannt geworden, der neben End- oder Zwischensteilung des Drei-Wege-Ventils 7, dem eigentlichen Kesselwärmetauscher einen nachge- nach der der Fluiddurchsatz durch den Wärmetauscher schalteten Abgaswärmetauscher für die den Kessel 35 3 mehr oder weniger gedrosselt bzw. freigegeben oder verlassenden Rauchgase aufweist. Im Zuge dieses abgesperrt ist Da der beginnenden Kondensation der Abgaswärmetauschers kann es sehr leicht zu Taupunkt- Rauchgase im Bereich der Abgasleitung 2 ein unterschreitungen der Rauchgase kommen, wobei bestimmter Temperaturwert zugeordnet werden kann. Kondenswasser entsteht, das bei ungenügender Abfuhr wird die Temperatur m der Abgasleitung 2 so geregelt, zu unangenehmen Korrosionserscheinungen führt. 40 daß sie sich gerade oberhalb des Taupunktes befindet.From DE-GM 77 10 693 a boiler for a temperature of the flue gases results in a certain Central heating system has become known, in addition to the end or intermediate division of the three-way valve 7, The actual boiler heat exchanger is followed by the fluid throughput through the heat exchanger switched exhaust gas heat exchanger for the boiler 35 3 more or less throttled or released or has leaving smoke gases. In the course of this, the beginning of the condensation is shut off Exhaust gas heat exchanger can very easily enter dew point flue gases in the area of the exhaust gas line 2 If the smoke gas falls below the limit, a certain temperature value can be assigned. Condensation water arises; if there is insufficient discharge, the temperature m of the exhaust pipe 2 is regulated in such a way that leads to unpleasant signs of corrosion. 40 that it is just above the dew point.
Aus der DE-OS 26 30 425 geht ein Durchlaufwasser- Stellgröße bei dieser Regelung ist der Durchsatz von heizer mit einer einem Wärmetauscher im Abgasweg aufzuheizendem Fluid durch den Wärmetauscher 3, mit nachgeschalteten Abgasklappe hervor, deren Stellung anderen Worten, der Wärmetauscher 3 wird mit so viel vom Wasserdurchsatz abhängig ist, und deren Stellung Fluid beaufschlagt, daß die Abgastemperatur nicht unter von einem Abgasfühler überwacht ist, der allerdings auf 45 einen bestimmten Wert fällt Das bedeutet, daß bei das Gasventil einwirkt und es schließt, wenn keine relativ tiefer Temperatur des eintretenden Fluids relativ normalen Abströmbedingungen herrschen. wenig Wasser den Wärmetauscher 3 durchsetzt,From DE-OS 26 30 425 is a flow water manipulated variable in this scheme is the throughput of heater with a fluid to be heated by a heat exchanger in the exhaust gas path through the heat exchanger 3, with downstream exhaust flap out whose position in other words, the heat exchanger 3 is with so much is dependent on the water throughput, and the position of which is acted upon by fluid that the exhaust gas temperature is not below is monitored by an exhaust gas sensor, which however falls to a certain value. This means that at the gas valve acts and it closes when the temperature of the entering fluid is not relatively low normal discharge conditions prevail. little water penetrates the heat exchanger 3,
Der vorliegenden Erfindung liegt die Aufgabe während bei relativ hoher Temperatur des eintretenden zugrunde, die Temperatur der Rauchgase konstant auf Wassers dieser Durchsatz recht hohe Werte annehmen Werten zu halten, die stets oberhalb des Taupunktes so kann. Das liegt daran, daß bei der erfindungsgemäßen liegen. Lösung Regelgröße die Abgastemperatur ist, währendThe present invention has the object of entering at a relatively high temperature based on the temperature of the flue gases constant on water this throughput assume quite high values To keep values that can always be above the dew point. This is because the invention lie. Solution controlled variable is the exhaust gas temperature while
Die Lösung dieser Aufgabe gelingt mit den die Stellgröße der Durchsatz durch den Wärmetauscher kennzeichnenden Merkmalen des Hauptanspruchs. 3 istThe solution to this problem is achieved with the manipulated variable, the throughput through the heat exchanger characterizing features of the main claim. 3 is
