Abstract
A preheater system for waste oil burners utilizes a primary preheater remote from the burner nozzle and a secondary preheater adjacent the burner nozzle. The primary preheater ordinarily provides heat to the waste oil when the burner is operating. The secondary preheater ordinarily maintains the waste oil adjacent the burner nozzle at atomization temperature when the burner is not operating. Flow of waste oil from the primary preheater to the burner nozzle is precluded when the burner is not operating.
