Abstract (en)
[origin: EP3029376A1] A Helmholtz damper (24), especially for damping pulsations in a combustor of a gas turbine, comprises a damper volume (25, which can be connected to a damped space (19) by means of a neck tube (26), and further comprises a piston (27), which is moveable within said damper volume (25) and divides said damper volume (25) into a variable first part (V1) on one side of said piston (27), which variable first part (V1) is connected to said neck tube (26), and a correspondingly variable second part (V2) on the other side of said piston (27). The control mechanism is substantially simplified in a more compact design by said piston (27) being driven by a pressure drop (”p) between said first and second part (V1, V2) of said damper volume (25).
