COMBUSTION CHAMBER OF GAS TURBINE Russian patent published in 2015 - IPC F23R3/34 

FIELD: machine building.

SUBSTANCE: combustion chamber of gas turbine contains pilot fuel injector located in the middle section of the cylinder opened at one end in the combustion chamber. The pilot fuel injector contains fuel injector, and cylindrical external enclosure radially spaced around the external perimeter of the fuel injector. Between the fuel injector and external enclosure the pilot turbulising element is located. Several main burners are located relatively to the radial direction around the pilot fuel injector. The pilot cone is made with internal side and external side, and is located at side of the combustion chamber on the pilot fuel injector, and at side of the combustion chamber has hole such that during air and pilot fuel mixing in the pilot cone (4) the pilot flame is created to ignite the fuel injected from the main burners. The pilot cone has on its internal side and external side the turbulising generators. The turbulising generators are trapezoidal and/or triangular straps located in hole of the pilot cone along the full hole circle. The trapezoidal and/or triangular straps are located in the pilot cone at angle +/-30°.

EFFECT: invention creates the combustion chamber that can be operated with increased flame temperature, and hence with increased efficiency.
