Abstract

Die Erfindung betrifft ein Regelungsverfahren für Gasbrenner.
Bei dem erfindungsgemäßen Regelungsverfahren wird zu vorbestimmten Zeitpunkten eine Kalibrierung der Regelung durchgeführt. In dem Fall, in dem im Anschluss an den vorbestimmten Zeitpunkt der Brenner für eine vorbestimmte Zeitspanne bei stabilen Betriebsbedingungen betrieben wird, wird eine neue stabile Kalibrierung ermittelt, die die vorhergehende stabile Kalibrierung ersetzt. Dann, wenn der Brenner nicht für die vorbestimmte Zeitspanne bei stabilen Betirebsbedingungen betrieben worden ist, wird eine vorläufige Kalibrierung auf Grundlage der zuletzt vorliegenden Betriebsbedingungen ermittelt.
