Regelung eines HeizungskesselsControl of a heating boiler
Die Erfindung bezieht sich auf die Regelung eines Heizungskessels in Abhängigkeit vom Wärmebedarf. The invention relates to the regulation of a heating boiler as a function of the heat demand.
Eine solche Regelung gehört zum allgemein bekannten Stand der Technik. Üblicherweise wird dabei die Kesselwassertemperatur auf einen Wert oberhalb des Taupunktes fest eingestellt, während die gewünschte Vorlauftemperatur durch mehr oder weniger starkes Beimischen von kälterem Rücklaufwasser erzielt wird. Der Wärmebedarf wird durch einen Temperaturfühler, vorzugsweise durch einen Außenthermostaten, ermittelt und durch ein geeignetes Regelgerät zur Regelung der Anlage verwandt.Such a regulation belongs to the generally known state of the art. Usually the boiler water temperature is used permanently set to a value above the dew point, while the desired flow temperature is through more or less strong admixture of colder return water is achieved. The heat demand is determined by a temperature sensor, preferably determined by an external thermostat and by a suitable control device for regulation related to the plant.
Die hoch eingestellte Kesselwassertemperatur führt zu hohen Energieverlusten durch Abstrahlung zum Kesselraum und durch Auskühlung zum Schornstein hin. Das trifft insbesondere in Übergangszeiten zu, in denen die hohen Kesselwassertemperaturen gar nicht notwendig wären und deshalb eine eindeutige EnergieVerschwendung darstellen.The high boiler water temperature leads to high energy losses through radiation to the boiler room and by cooling down towards the chimney. This is especially true in transitional periods when the boiler water temperatures are high would not be necessary at all and therefore represent a clear waste of energy.
Der Erfindung liegt die Aufgabe zugrunde, die Regelung eines Heizungskessels so zu optimieren, daß die Energieverluste wesentlich reduziert werden. Der Wirkungsgrad des Heizungskessels soll über das bisher bekannte Maß hinaus erhöht werden.The invention is based on the object of optimizing the control of a heating boiler so that the energy losses can be significantly reduced. The efficiency of the heating boiler should exceed the previously known level increase.
Dieses wird gemäß der Erfindung durch die im Kennzeichen des Patentanspruches 1 genannte Maßnahme erreicht.This is achieved according to the invention by the measure mentioned in the characterizing part of claim 1.
130065/0578130065/0578
Die hohen Auskühlverluste des Heizungskessels wurden bereits mit bestem Erfolg durch eine Anpassung der Kesselwassertemperatur an den jeweils vorliegenden Wärmebedarf vermieden. Bei einer solchen Regelung, bei der unter bestimmten Bedingungen sogar der Taupunkt unterschritten werden kann, entspricht die Vorlauftemperatür der Kesselwassertemperatur. Auf einen nachgeschalteten Mischer kann deshalb im Normalfall verzichtet werden. Eine Regelung dieser Art ist in der DE-OS 25 28 749 beschrieben.The high cooling losses of the heating boiler have already been met with great success by adjusting the boiler water temperature avoided at the respective existing heat demand. In such a scheme, with which under certain Conditions can even fall below the dew point, the flow temperature corresponds to the boiler water temperature. A downstream mixer can therefore normally be dispensed with. A scheme this type is described in DE-OS 25 28 749.
Durch diese Anpassung der Kesselwassertemperatur an die Außentemperatur und somit an den Wärmebedarf wurden die Auskühlverluste des Heizungskessels in Übergangszeiten wesentlich reduziert. Die Kombination dieser bekannten Maßnahme mit der gleichzeitigen Anpassung der Brennerleistung an den Wärmebedarf führt zu einer zusätzlichen Steigerung des Kesselwirkungsgrades und zu einer Optimierung der Regelung. Der bisher übliche Betrieb des Brenners mit voller Leistung führte nämlich bei geringem Wärmebedarf und geringen Kesselwassertemperaturen zu einem für diesen Bedarfsfall nicht notwendigen Überangebot an Energie, welches keine optimalen Ergebnisse brachte.By adapting the boiler water temperature to the outside temperature and thus to the heat demand, the Cooling losses of the heating boiler significantly reduced in transitional periods. The combination of these well-known Measure with the simultaneous adjustment of the burner output to the heat demand leads to an additional Increase of the boiler efficiency and an optimization of the control. The usual operation of the burner up to now with full power, with low heat demand and low boiler water temperatures, one for this If there is an unnecessary excess supply of energy, which did not bring optimal results.
Die Kombination der beiden Maßnahmen, nämlich der an sich bekannten Anpassung der Kesselwassertemperatur an den Wärmebedarf mit der gleichzeitigen Anpassung der Brennerleistung führt zu Ergebnissen, die über die Ergebnisse der Einzelmaßnahmen hinausgehen. Die Anpassung kann dabei stetig oder stufenförmig erfolgen.The combination of the two measures, namely the one in itself known adjustment of the boiler water temperature to the heat demand with the simultaneous adjustment of the burner output leads to results that go beyond the results of the individual measures. The adjustment can thereby be carried out continuously or in steps.
Die beigefügte Zeichnung stellt in einem einzigen Dia·· gramm die Ergebnisse von drei Versuchsreihen dar.The attached drawing represents in a single slide shows the results of three test series.
Auf der Abszisse ist die Belastung des Kessels dargestellt. Diese ist dem Wärmebedarf gleich, der beispielsweise durchThe load on the boiler is shown on the abscissa. This is the same as the heat demand, for example through
130065/0578130065/0578
die jeweils vorliegende Außentemperatur ermittelt wird. Auf der Ordinaten ist der jeweilige Kesselwirkungsgrad dargestellt.the prevailing outside temperature is determined. The respective boiler efficiency is on the ordinate shown.
Die Kurve (1) zeigt die Ergebnisse der erfindungsgemäßen Kombination der beiden Maßnahmen. Die Kurve (2) zeigt die Ergebnisse bei einer stetigen Anpassung der Kesselwassertemperatur an den Wärmebedarf, jedoch mit der bisher üblichen vollen Brennerleistung. Die Kurve (^) zeigt die Ergebnisse bei einer stetigen Anpassung der Brennerleistung an den Wärmebedarf, jedoch mit einer fest eingestellten Kesselwassertemperatur von 80 0C.The curve (1) shows the results of the combination of the two measures according to the invention. The curve (2) shows the results with a constant adjustment of the boiler water temperature to the heat demand, but with the previously usual full burner output. The curve (^) shows the results with a constant adjustment of the burner output to the heat demand, but with a fixed boiler water temperature of 80 ° C.
Bei voller Belastung, d.h. bei extrem niedrigen Außentemperaturen, ist der Kesselwirlcungsgrad in allen Fällen gleich. Zu niedrigen Belastungen hin, nämlich in Übergangszeiten mit höheren Außentemperaturen, steigt der Kesselwirkungsgrad in allen drei Fällen an. Die Kurve (1) steigt jedoch wesentlich steiler als die Kurven (2 und 2). Ihr Anstieg ist so groß, daß er sogar noch die theoretische Addition der Anstiege der beiden anderen Kurven übertrifft. Die Kombination der beiden Maßnahmen bringt somit einen überragenden und nicht zu erwartenden Effekt.At full load, i.e. at extremely low outside temperatures, the boiler degree of circulation is the same in all cases. Towards low loads, namely in transitional periods with higher outside temperatures, the boiler efficiency increases in all three cases. The curve (1) however, it rises much more steeply than the curves (2 and 2). Its rise is so great that it even exceeds the theoretical addition of the increases in the other two curves. The combination of the two measures thus has an outstanding and unexpected effect.
