HEAT SHIELD ELEMENT FOR THE COMPRESSOR AIR PASS BY AROUND THE COMBUSTION CHAMBER Russian patent published in 2017 - IPC F23R3/00 F23R3/06 

FIELD: power industry.

SUBSTANCE: element (14) of the heat shield, in particular, for lining a combustion chamber wall, including the first wall (17) with the hot side (18), to which the hot medium can be supplied, from the opposite to hot side (18) the cold side (19), and the circular edge (24), which extends along the first lateral side (20), the second lateral side (21) and the third lateral side (22) of the first wall (17) beyond the cold side (19) limits, generally, upto the first height (25), wherein the circular edge (24) on the fourth lateral side (23) extends to the second height (26), which is less than the first height (25) and that, in general, at the second height (26), the second wall (27) is opposite to the cold side (19) and extends across the width of the fourth side (23) from the fourth lateral side (23) through the length part of the adjacent to the fourth lateral side (23) of the lateral sides (20, 22), at that the second side (27) at its end (28), directed from the fourth lateral side (23) has the edge (29), which extends upto the first height (25). The combustion chamber and gas turbine is also presented.

EFFECT: invention allows to implement the bypass air flow into the hot air flow without serious modification of structural elements, feeding the hot gas.
