BURNER LIE Russian patent published in 2018 - IPC F23R3/28 F23R3/10 

FIELD: power engineering.

SUBSTANCE: invention refers to power engineering. Burner lie (1) with combustion chamber (2), with plurality of dilution tunnels (3) flowing into combustion chamber (2) is proposed, in which combustion air (4) entering at operation according to instruction and incoming fuel (5) are mixed, dilution tunnels (3) are formed by mixing tubes (6) passing in axial direction through annular cavity (7), defined between tubular outer wall (8), located radially at some distance from outer wall by tubular inner wall (9), positioned upstream by annular end plate (10) and downstream by annular end plate (11), end plates (10, 11) are provided with through holes (12) accommodating mixing tubes (6) and / or extending them and having radially outward and radially outward extension in direction of annular cavity (7), enveloping edge (13, 14), moreover axial drillings (15) are provided in edge (13, 14) located downstream of annular end plate (11) which passes, in essence, parallel to perpendicular of end plate (11) from annular cavity (7) to end plate (11), and there is at least one opening (16) for withdrawing cooling air (17) from axial drilling (15).

EFFECT: invention allows to improve operational reliability of burner.
