ABSTRACT:
A burner apparatus comprising: a liquid fuel discharge means for discharging a liquid fuel; an ignition chamber wherein an ignitable gaseous composition can be ignited to yield an ignited composition; and a gas delivery means for delivering a gaseous, free oxygen source and a combustible gas to the ignition chamber such that the ignitable gaseous composition is provided in the combustion chamber. The ignition chamber is positioned with respect to the liquid fuel discharge means such that, upon leaving the ignition chamber, the ignited gaseous composition will ignite the liquid fuel as the liquid fuel is discharged from the discharge means. Preferably, the gas delivery means includes a conduit through which the free oxygen source is conducted into the ignition chamber. The gas delivery means also preferably includes a passageway, adjacent the exterior of the conduit, through which the combustible gas is conducted into the ignition chamber. The gas delivery passageway preferably substantially surrounds the oxygen source delivery conduit. Additionally, the liquid fuel discharge means preferably discharges the liquid fuel into a combustion chamber substantially having an inverted frusto-conical shape.
