CENTRIFUGAL OXYGEN-AND-OIL BURNER Russian patent published in 2003 - IPC

FIELD: liquid fuel combustion. SUBSTANCE: oxygen and liquid fuel burner has external casing incorporating first inlet end, second outlet end for flame escape in burning that forms combustion chamber and has longitudinal axis X; fuel feed means for passing atomized fuel flow to inlet end and directing it to outlet end, as well as oxygen feed means for injecting oxygen into inlet end and directing it to outlet end; oxygen feed means has plurality of oxygen outlet holes disposed over circumference around fuel feed means and at certain angle in radial inward direction toward outlet end and skewed relative to X axis thereby forming conically converging oxygen flow that crosses fuel flow in region first along flow; fuel feed means has essentially central outlet hole with inner surface in the form of diverging cone passing fuel as it flows out; inner surface of diverging cone has first diverging-cone surface adjacent to central outlet hole and is characterized in that inner surface of diverging cone is provided in addition with second diverging-cone surface abutting against first diverging-cone surface, first of these surfaces having higher angle of deflection from X axis than second one. EFFECT: reduced nitrogen oxide content in combustion products. 16 cl, 9 dwg
