Abstract
Description
Die Erfindung betrifft ein Verfahren zum Betrieb eines Heizkessels mit mindestens zwei Brennerstufen nach dem Oberbegriff des Patentanspruches 1.The The invention relates to a method for operating a boiler with at least two burner stages according to the preamble of claim 1.
Heizkessel besitzen zwei oder mehr Brennerstufen, um die Wärmebelastung optimal an die Wärmeanforderung aus mindestens einem wärmeverbrauchenden Heizkreislauf mit einer Umwälzpumpe anzupassen. Bei mehrstufigen Brennern wird die erste Brennerstufe üblicherweise nur auf einen Teil der Nennleistung des Heizkessels ausgelegt, um damit geringere Wärmeanforderungen abzudecken. Die Zu- und Abschaltung des Brenners und/oder der Brennerstufen erfolgt nach kessel-, anlagen- und nutzerspezifischen Vorgaben. So wird mit einer Messeinrichtung in Form eines Temperaturfühlers die aktuelle Betriebstemperatur des Heizkessels erfasst und mit einem Regelgerät einerseits eine feuerungs- und/oder kesselspezifische Betriebstemperatur des Heizkessels vorgegeben. Dabei fließen beispielsweise in die Berechnung der Betriebstemperatur Mindestein- und Mindestausschalttemperaturen, Brennerlaufzeiten sowie sicherheitstechnische Grenzwerte ein. Andererseits wird vom Regelgerät, entsprechend der aktuellen Wärmeanforderung mindestens eines Verbrauchers, eine Solltemperatur des Heizkessels vorgegeben.boiler have two or more burner stages to optimally adjust the heat load to the heat requirement from at least one heat-consuming Heating circuit with a circulation pump adapt. In multi-stage burners, the first burner stage becomes common only to a part of the rated capacity of the boiler designed to thus lower heat requirements cover. The connection and disconnection of the burner and / or the burner stages takes place according to boiler, plant and user specific specifications. Thus, with a measuring device in the form of a temperature sensor the current operating temperature of the boiler detected and with a regulator on the one hand a combustion and / or boiler specific operating temperature of the boiler specified. For example, the calculation is used for this the operating temperature minimum and minimum switch-off temperatures, Burner run times and safety limits. on the other hand is from the controller, according to the current heat requirement at least one consumer, a setpoint temperature of the boiler specified.
In der Regel besitzen Heizungsanlagen eine Frostschutzfunktion, welche ab einer Außentemperatur in Gefrierpunktnähe einen Dauerbetrieb der Umwälzpumpen bewirkt. Gleichzeitig sieht eine sogenannte Nachtabsenkung eine reduzierte Solltemperatur des Heizkessels vor, um Energie einzusparen. Liegt dann die Wärmebelastung im Leistungsbereich zwischen der ersten und zweiten Brennerstufe und wird von der Regelung wegen der Nachtabsenkung eine Solltemperatur des Heizkessels gefordert, welche im Bereich unterhalb der geforderten Betriebstemperatur des Heizkessels liegt, so würde der Brenner nach dem Umschalten auf die Nachtabsenkung bei gleichzeitig aktivierter Frostschutzfunktion der Umwälzpumpen nicht mehr abschalten. Begründet ist dies damit, dass in diesem Betriebszustand eine Abschaltung wegen der relativ hohen Belastung verhindert wird.In Usually heating systems have a frost protection function, which from an outside temperature near the freezing point a continuous operation of the circulation pumps causes. At the same time sees a so-called night lowering one Reduced set temperature of the boiler in order to save energy. Lies then the heat load in the power range between the first and second burner stage and becomes a target temperature of the night-fall control required of the boiler, which in the area below the required Operating temperature of the boiler, the burner would after switching on the night reduction with simultaneously activated frost protection function the circulation pumps do not turn off anymore. Is justified this with the fact that in this operating condition a shutdown because the relatively high load is prevented.
Der Erfindung liegt die Aufgabe zu Grunde, ein Verfahren zum Betrieb eines Heizkessels mit mindestens zwei Brennerstufen zu schaffen, welches einen optimalen Betrieb des Heizkessels in der Nachtabsenkung mit einer reduzierten Solltemperatur bei gleichzeitig aktivierter Frostschutzfunktion für die Heizungsanlage bietet.Of the The invention is based on the object, a method of operation to create a boiler with at least two burner stages, which ensures optimal operation of the boiler in the night setback with a reduced setpoint temperature with simultaneously activated Frost protection function for the heating system offers.
Erfindungsgemäß wird dies mit den Merkmalen des Patentanspruches 1 gelöst. Vorteilhafte Weiterbildungen sind den Unteransprüchen zu entnehmen.According to the invention this is solved with the features of claim 1. Advantageous developments are the dependent claims refer to.
Das Verfahren zum Betrieb eines Heizkessels mit mindestens zwei Brennerstufen ist dadurch gekennzeichnet, dass während des Brennerbetriebes bei aktivierter Frostschutzfunktion und bei einer Solltemperatur des Heizkessels unterhalb der geforderten Betriebstemperatur des Heizkessels mindestens eine Umwälzpumpe so lange ausgeschaltet wird, bis der Brenner bzw. die erste Brennerstufe durch Erreichen der geforderten Betriebstemperatur abschaltet.The Method of operating a boiler with at least two burner stages is characterized in that during burner operation with activated frost protection function and with a setpoint temperature of the boiler below the required operating temperature of the Boiler at least one circulation pump is turned off until the burner or the first burner stage by Switch off the required operating temperature switches off.
In diesem speziellen Betriebszustand, nämlich wenn die Solltemperatur des Heizkessels unterhalb der geforderten Betriebstemperatur des Heizkessels liegt, wird die Nachtabsenkung für die Solltemperatur des Heizkessels erst nach dem Ausschalten des Brenners bzw. der ersten Brennerstufe aktiv. Außerdem wird in diesem Betriebszustand mindestens eine Umwälzpumpe für eine vorgegebene Zeitspanne von vorzugsweise 5 Minuten ausgeschaltet, um den Brenner bzw. die erste Brennerstufe durch Erreichen der geforderten Betriebstemperatur abzuschalten.In this special operating condition, namely when the set temperature of the boiler below the required operating temperature of the Boiler is set, the night setback will be for the setpoint temperature of the boiler only after switching off the burner or the first burner stage active. Furthermore In this operating state, at least one circulating pump for one predetermined period of preferably 5 minutes off to the burner or the first burner stage by reaching the required To switch off operating temperature.
Ergänzend oder alternativ zu den vorstehenden Schritten kann während des Brennerbetriebes in der ersten Brennerstufe bei aktivierter Frostschutzfunktion und bei einer Solltemperatur des Heizkessels unterhalb der geforderten Betriebstemperatur des Heizkessels mindestens eine zusätzliche Brennerstufe so lange eingeschaltet werden, bis der Brenner bzw. die erste Brennerstufe durch Erreichen der geforderten Ausschalttemperatur abschaltet.Complementary or Alternatively to the above steps, during burner operation in the first burner stage with activated frost protection function and at a setpoint temperature of the boiler below the required Operating temperature of the boiler at least one additional Burner stage are turned on until the burner or the first burner stage by reaching the required switch-off temperature off.
Mit der Erfindung steht ein Verfahren zum Betrieb eines Heizkessels mit mindestens zwei Brennerstufen zur Verfügung, mit dem ein optimaler Betrieb des Heizkessels in der Nachtabsenkung mit einer reduzierten Solltemperatur bei gleichzeitig aktivierter Frostschutzfunktion für die Heizungsanlage gewährleistet ist. Eine Abschaltung des Brenners bzw. der ersten Brennerstufe ist somit auch in speziellen Betriebszuständen sichergestellt. Es wird Energie gespart und die Vorteile eines modernen Heizungsregelsystems werden ausgenutzt.With The invention relates to a method for operating a boiler with at least two burner stages available, with which an optimal Operation of the boiler in the night reduction with a reduced Setpoint temperature with simultaneously activated frost protection function for the Heating system guaranteed is. A shutdown of the burner or the first burner stage is thus ensured even in special operating conditions. It will Energy saved and the advantages of a modern heating control system are being used.
