An oil burner atomizer and method for light and heavy fuel oils where the oil is spread circumferentially of a number of oil delivery bores and two heavy oil flows are formed for each delivery bore. The oil flows are atomized in low-pressure primary air. The atomizer includes an annular low-pressure oil ligament formation zone upstream of the initial atomizing air flow.

A fuel atomizer for an industrial heating burner or the like comprising a body having an upstream end, a central fuel passage extending into the body from the upstream end, a plurality of fuel feed passages spaced circumferentially around the central passage and extending outwardly therefrom, a plurality of circumferentially spaced hollow spreading chambers each located at the outer end of a feed passage and including a mouth facing downstream and a spreading wall overlying the end of the fuel passage, the spreading wall extending circumferentially to each side of the feed passage, and an air delivery system for flowing atomizing air across the spreading chamber mouths whereby fuel oil flowed through said passages and into the spreading chambers flows to each side of the chambers and forms a pair of fuel streams located circumferentially of the feed passages for atomization by the air flow.
