COMBUSTION CHAMBER FUEL SUPPLY SYSTEM Russian patent published in 1998 - IPC

FIELD: mechanical engineering; fuel supply systems. SUBSTANCE: in proposed fuel supply system with combustion of preliminarily prepared mixture, gaseous and/or liquid fuel is injected, as additional flow, into main gaseous flow passing along channel. Additional flow is considerably smaller in mass than main flow. Main flow is directed through vortex generators 9, many of which are arranged in row over circumference of channel on at least one wall of channel. Additional flow is introduced into channel directly from area of location of cortex generators 9. Vortex generator 9 has three freely flow-passed planes orientated in direction of flow, one of which is upper plane 10 and two others are side planes 11 and 13. Fuel is delivered into channel through nozzle found behind vortex generators or inside the generators. EFFECT: enhanced quality of mixing, increased duration of swirling. 16 cl, 21 dwg
