An industrial burner having an axial recirculation flame with active vortex mixing in the combustion chamber and method.

Burner and method

A multi-fuel industrial heating burner having an exhaust velocity of about 15,000 feet per minute. The fuel is first burned in a swirling toroidal recirculation zone and flows into the burner tile and shear mixes with a counter-swirling flow of combustion air flowing along the burner tile. As the flows shear mix, additional combustion air is provided to the central burning gases and the rotational momentum of the swirling flows is dissipated. The burner discharge gases flow axially without swirl.

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.
