METHOD OF BURNING FUEL Russian patent published in 1995 - IPC

FIELD: power mechanical engineering. SUBSTANCE: at burning fuel in a combustion chamber air flow is preliminary separated into ring coaxial jets. Adjacent jets is swirled in opposite directions, and nearest parts of the swirled air jets and fuel jets is fed to semi-bounded space for forming over- rich fuel-air mixture, creating circulating burning zones, and partially burning out of fuel at air-fuel ratio of 0.6-0.8. The remainder parts of the swirled air jets enter confined space for forming poor fuel-air mixture and creating circulating burning zones. EFFECT: enhanced efficiency. 5 dwg
