BURNER Russian patent published in 2017 - IPC F23R3/14 F23D17/00 

FIELD: power industry.

SUBSTANCE: burner of the gas turbine extends along the axis (X) and contains in the axial order: the swirl section (SW), the mixing section (MX), the output section (OT), the main combustion zone (CZ). Wherein the mentioned mixing section (MX) conducts the premix (MFOCG) of the fuel (F) and the oxygen-containing gas (OCG) to the mentioned output section (OT), which produces the mentioned premix (MFOCG) to the specified combustion zone (CZ), expanding the premix stream (MFOCG) from the smaller axial cross-section of the mentioned mixing section (MX) upto the larger cross-section area of the mentioned combustion zone (CZ), which causes the radial deflection of the mentioned flow current lines. To improve the stability of the outlet section (OT) surface, facing the mentioned premix (MFOCG) flow, provided with a first fuel injectors (FN1), injecting the fuel into the mentioned premix (MFOCG) in the deflected radially inward direction before the flow of the mentioned premix (MFOCG) enters into the mentioned output section (OT) and into the mentioned combustion zone (CZ).

EFFECT: invention allows to increase the combustion stability.
