Abstract (en)

A gas turbine for a power plant; the gas turbine having an axis and comprising following the gas flow direction: a compressor sector for compressing ambient air, a plenum delimited by an outer casing (17) for receiving the compressed; a combustor (4) at least in part housed in the plenum for mixing and combusting the compressed with at least a fuel; at least a turbine for expanding the combusted hot gas flow leaving the combustors and performing work on a rotor; wherein the combustor comprising: at least a burner; at least a liner (7) downstream the burner and defining an inner combustion chamber; a damper (28) comprising a damper body defining a damping volume wrapped outside around the liner and in fluid connection with the combustion chamber; wherein the damper body is spaced from the liner in order to form a cooling gap (31) between the damper body and the liner, being present at least a damper neck (32) acting as a bridge in the cooling gap between the liner and the damper body for fluidly connecting the damping volume with the combustion chamber, at least the damper body is mechanically decoupled by the liner and supported in position by a supporting structure at one side fixed to the damper body and at another side fixed to the outer casing.
