FLAME STABILIZER OF THE BURNER UNIT OF A LOW-EMISSION SINGLE-MODULE COMBUSTION CHAMBER Russian patent published in 2023 - IPC F23R3/18 

FIELD: engine technology.

SUBSTANCE: invention relates to ground-based gas turbine engines and can be used to burn pre-mixed gaseous fuel-air mixtures in the combustion chambers of gas turbine engines and gas turbine installations. In the flame stabilizer of the burner unit of the combustion chamber of a gas turbine engine, the conical surface is made with external and internal sides, additionally cooling of the stabilizer is performed from the outside of the conical surface and hollow U-shaped lobes, while the outer side of the conical surface and hollow U-shaped lobes of the flame stabilizer are cooled by a fuel-air mixture coming from the mixing channel into the cooling holes, the diameter of the cooling holes of the outer conical surface and hollow U-shaped lobes is made in the range of 0.6 to 1.5 mm, the feed holes of the pilot gaseous fuel are equally located at the end of the conical surface of the stabilizer, and their number is 2N, where N is the number of stabilizer lobes.

EFFECT: invention makes it possible to ensure high completeness of fuel combustion in a wide range of modes of operation of the gas turbine engine, as well as to ensure the resource characteristics of the stabilizer.
