FUEL COMBUSTION METHOD Russian patent published in 2014 - IPC F23R3/34 F02C7/22 

FIELD: engines and pumps.

SUBSTANCE: invention refers to energetic, chemical and transport machine building and may be used in gas turbine plants combustion chambers. Proposed fuel combustion method involves preliminary separation of air flow into coaxial annular jets, twisting of neighbouring adjacent jets in opposite directions, at that parts of neighbouring twisted in opposite directions jets closest to each other are supplied in radial direction towards each other forming turbulent shifting layer. Fuel is supplied to this layer for further ignition of generated fuel-air mixture. Preliminary right after air flow separation into coaxial annular jets, one part of fuel is supplied to generated rotating coaxial annular jets tangentially, contrary to direction of coaxial annular air jet rotation preferably to direction opposite to its axial movement. The rest part is supplied to generated turbulent shifting layer in direction of combustion zone, preferably in the form of hollow annular jet formed from several continuous single fuel jets. 40-50% of total fuel flow is supplied tangentially, and the rest part of fuel flow is supplied to generated turbulent shifting layer.

EFFECT: enhancement of the method efficiency.
