摘要：
A burner 1 of a reheat gas turbine engine has a body 2 that may be annular and includes an inner wall 7 and an outer shell 8. The burner further includes a front panel 5a, 5b which may include a damper 10 to dampen thermo-acoustic oscillations during the combustion process in the combustion zone 6. The burner can include a mixing zone 4 downstream of fuel injection heads 3, and the inner wall and outer shell are provided with convective cooling, i.e. a cooling air flow is provided sweeping over the wall and shell in a counter current direction. The inner wall and outer shell can have a hollow structure, with a chamber or a number of axial channels, and can include ribs and/or turbulators for cooling heat transfer enhancement. In use, cooling air is then exhausted in the hot gas via film cooling holes 20 provided close to the trailing edge of the injector heads. The arrangement reduces the required cooling air mass flow consumption and minimizes the cold near wall layer at the inner wall and outer shell. This improves emission performance and increases the flame temperature.

权利要求：
CLAIMS 1. A burner of a reheat gas turbine engine comprising a body with an inner wall and an outer shell and a front panel, wherein the inner wall and outer shell are provided with convective cooling only. 2. The burner of claim 1, wherein the inner wall and outer shell have a hollow structure, with a chamber extending over all the inner wall and outer shell or a number of channels directed axially or along a direction inclined with respect to an axial axis. 3. The burner of any of the previous claims, wherein the front panel carries at least a damper for damping thermo-acoustical oscillations that may be generated during operation of the gas turbine engine. 4, The burner of any of the previous claims, wherein the front panel is produced by additive manufacturing and has near wall cooling channels. 5. The burner of the previous claim, wherein the near wall cooling channels are uniformly distributed within the front panel and are oriented radially.
