METHOD OF BURNER USE, BURNER, IN PARTICULAR FOR GAS TURBINE AND GAS TURBINE Russian patent published in 2014 - IPC F23R3/28 

FIELD: power industry.

SUBSTANCE: method of burner use, comprising an axis and at least one jet nozzle is proposed. One jet nozzle includes centre axis, exit and wall facing to the burner axis in the radial direction starting from the centre axle. The mass flow of fluid medium including fuel, flows through at least one jet nozzle to its outlet. At outlet of jet nozzle between the mass flow of liquid medium activating the fuel and wall facing to burner axis, air film or inert gas is created due to the fact that air or inert gas is injected along the wall facing towards the burner axis at least into one jet nozzle. Another object of the present invention is burner, comprising axis and at least one jet nozzle. One jet nozzle includes centre axis and wall portion extending around the centre axis in the angular range maximum from -135° to +135°, and at least from -15° to +15° relative to the radial connecting line between the burner axis and central axis. Exceptionally wall portion extending around the centre axis in the angular range of maximum from -135° to +135° and at least from -15° to +15°, includes at least one flow channel for supplying air or inert gas inflowing to jet nozzle. Gas turbine comprising one burner described above is also a subject of invention.

EFFECT: invention permits to optimise the use of air films or films of inert gas for operation of jet burner.
