BURNER DEVICE OF A LOW-EMISSION COMBUSTION CHAMBER AND A METHOD FOR REGULATING THE FLOW OF AIR ENTERING IT Russian patent published in 2022 - IPC F23R3/22 F23D14/60 

FIELD: engine technology.

SUBSTANCE: invention relates to combustion chambers of gas turbine engines using natural gas, and can be used in marine and land-based engines. The burner device of the low-emission combustion chamber, installed at the entrance to the heat pipe, contains a housing including a fitting, a radial swirl, fuel supply channels, and a mixing chamber. At least one of the fittings has an adjustable valve block consisting of support elements, one of which is presented in the form of a sleeve with an external thread, a spring, a shut-off element made in the form of a preload rod with a plug, while holes are made in the ring of the mixing chamber with a total area, ensuring the operation of the burner device when gas is supplied only in the first: starting, fuel channel with a closed section at the entrance to the swirler.

EFFECT: increase in the reliability of regulating the flow of air entering the burner over the entire range of engine operation by regulating the flow area of the burner, using the pressure of fuel gas entering the burner cavity for this purpose.
