Abstract
A main burner oil gun in which hard to ignite liquid fuels can be burned, including an ignition means for the oil gun which will reliably light the oil gun time after time. The oil is sprayed from the oil gun tip in the shape of a hollow cone. Air is introduced surrounding the oil gun, and flows over a baffle plate located transversely of the oil gun, creating eddies of air, some of which break through the curtain of fuel issuing from the tip in a conical shape. This current of air that breaks through the fuel carries some fine droplets of fuel along with it, and forms a recirculation zone extending back to the oil gun tip. The ignition means is located within the hollow conical fuel flow, along the inner edge of the recirculation zone, so that the initial flame established is carried back to a point directly in front of the oil gun tip.
