ANNULAR COMBUSTION CHAMBER BURNER Russian patent published in 2025 - IPC F23R3/50 F23R3/14 F23D14/24 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to burners of combustion chambers of gas turbine engines operating mainly on gaseous fuel. Annular combustion chamber burner device comprising a swirler housing, a fuel injector flanged to the combustion chamber shell, the swirler housing is installed in the annular head, characterized by that in the hole of the swirler housing there is a mixer bushing having a hollow channel ending with an annular wall on which holes are applied along the circumference, in the middle of the annular wall there is a collar, which changes into a cylindrical rod, on which a stabilizer screen in the form of a truncated cone is installed, in the outlet part, the annular wall has a step with a chamfer, between the chamfer and the conical part of the stabilizer screen, a channel L is formed, which is controlled by the size of the collar M, on mixing sleeve surface there are two rows of tangential channels directed in opposite direction, nozzle end comprises two rows of holes, diffuser-shaped hole is located at nozzle outlet, nozzle end is installed in the middle of hollow channel of mixing sleeve.

EFFECT: providing low concentration of nitrogen oxides and carbon oxides, high quality of mixing fuel with air, uniformity of temperatures in the combustion zone, stability of combustion in the combustion chamber, cooling of the burner device.
