its a babington ball waste oil burner...for those that don't know a babington burner works like a whales blowhole, oil flowing over the surface of the burner ball makes a thin film about 3 to 5 thousandths of an inch thick...this film of oil is pierced by a jet of compressed air from a .010" hole in the ball which atomizes the oil
enjoy...and remember there is no such thing as a dumb question...only people with no imagination that are too dumb to ask questions in the first place
