MODULAR INJECTION HEAD FOR THE COMBUSTION CHAMBER OF A GAS TURBINE Russian patent published in 2022 - IPC F23R3/14 F23R3/28 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to a modular injection head for the combustion chamber of a gas turbine. Injection head comprises a swirler and a fuel insert extending around the central axis, the swirler comprises multiple hollow streamlined blades (21) extending in a radial direction around the central axis, and flow channels (22) formed between adjacent blades (21), wherein the swirler comprises a first casing (18a) defining the boundary of the front part of the blades (21), and a second casing (18b) defining the boundary of the back part of the blades (21), wherein the first casing (18a) and the second casing (18b) are interconnected on a connecting surface transverse to the central axis. The fuel insert comprises a block of chambers extending around the central axis and multiple injection pins (31, 32), wherein each pin extends in a radial direction outward from the block (30) of chambers and is provided with at least a corresponding fuel nozzle (35), the injection pins (31, 32) are at least partially covered by corresponding hollow blades (21), and the fuel nozzles (35) are arranged so as to pass through the second casing (18b).

EFFECT: invention allows for a simplification in the process of assembly, improvement in the quality of fuel combustion.
