Abstract

Bei Standheizungen mit Druckzerstäuberbrennern, die ein geringes Brennkammervolumen aufweisen, wird eine gute Durchmischung von Luft und Brennstoff praktisch nur bei relativ hohen Luftströmungsgeschwin­ digkeiten erreicht, was aber zu Zündschwierigkeiten, insbesondere bei hohen Betriebsspannungen und tiefen Temperaturen führt. Deshalb wird beim Inbetriebnehmen des Heizgerätes zunächst der Gebläsemotor einge­ schaltet, dann spannungslos geschaltet, so daß die Drehzahl wieder ab­ nimmt, und dann werden Hochspannungszündung und Brennstoffzufuhr ein­ geschaltet, so daß die Zündung bei verringerter Gebläsedrehzahl erfol­ gen kann, und nach Erkennen der Flamme im Brenner wird die Hochspan­ nungszündung ausgeschaltet und der Gebläsemotor wieder eingeschatet. For parking heaters with pressure atomizing burners, which is a low one Combustion chamber volume, a good mixing of air and fuel practically only at relatively high air flow speeds achieved, but this leads to ignition difficulties, especially when high operating voltages and low temperatures. That is why When starting up the heater, the blower motor is first switched on switches, then switched off so that the speed decreases again takes, and then high voltage ignition and fueling come on switched so that the ignition succeeds at a reduced fan speed can, and after detection of the flame in the burner, the high voltage Ignition switched off and the blower motor switched on again.
