ANNULAR COMBUSTION CHAMBER FOR TURBO-MACHINE Russian patent published in 2016 - IPC F23R3/14 

FIELD: turbo-machines.

SUBSTANCE: annular combustion chamber for turbo-machine contains coaxial annular inner wall and outer wall, connected at their upstream located ends by means of annular wall, forming chamber bottom, annular row of fuel nozzles, which heads are installed into fuel injection systems, installed chamber bottom wall openings. Each nozzle head has longitudinal axis and comprises, at least, fuel screw passage to drive said fuel into rotation around nozzle head longitudinal axis. Each injection system comprises, at least, one twist, located at same longitudinal axis as nozzle head, and having substantially radial air passage channels, having corresponding longitudinal axes, along which each channel has longitudinal cross-section. Channels longitudinal cross-sections longitudinal axes are inclined relative to twist longitudinal axis at angle, which is substantially equal to, within ±10°, angle of nozzle head screw channel helical line. Channels cross-sections longitudinal axes are oriented in same direction as said channel, around twist longitudinal axis.

EFFECT: invention is aimed at combustion chambers higher efficiency and effectiveness.
