In other words, when the burner surface is cold, the predetermined level of air-fuel ratio (ratio of combustion air from the blower to oil fuel from the oil supply means, hereinafter referred to as air-fuel ratio) is set to excess fuel to improve ignition. On the other hand, if the burner is sufficiently salty, the air-fuel ratio is returned to the predetermined normal setting, and the ignition performance is always maintained constant by igniting at an air-fuel ratio that corresponds to the burner surface salinity. Therefore, the generation of white smoke, odors, etc. can be constantly reduced.
