HELMHOLTZ DAMPER AND GAS TURBINE WITH SUCH A HELMHOLTZ DAMPER |
| 摘要 |
A Helmholtz damper, especially for damping pulsations in a combustor of a gas turbine, including a damper volume, which can be connected to a damped space by means of a neck tube. The Helmholtz damper further includes a piston, which is moveable within the damper volume and divides the damper volume into a variable first part (V1) on one side of said piston. The variable first part (V1) is connected to the neck tube, and a correspondingly variable second part (V2) on the other side of said piston. The control mechanism is substantially simplified in a more compact design by the piston being driven by a pressure drop (Δp) between the first and second part (V1, V2) of the damper volume. |

1. A Helmholtz damper, especially for damping pulsations in a combustor of a gas turbine, comprising a damper volume, which can be connected to a damped space by means of a neck tube, and further comprising a piston, which is moveable within said damper volume and divides said damper volume into a variable first part (V1) on one side of said piston, which variable first part (V1) is connected to said neck tube, and a correspondingly variable second part (V2) on the other side of said piston, wherein said piston is driven by a pressure drop (Δp) between said first and second part (V1, V2) of said damper volume. |
