DAMPING DEVICE FOR DAMPING PRESSURE OSCILLATIONS WITHIN A COMBUSTION CHAMBER OF A TURBINE |
摘要 |
A damping device (122; 222; 322; 422; 522) for damping pressure oscillations within a combustion chamber (106; 206; 306; 406; 506) of a turbine (102; 202; 302; 402; 402; 502) comprises a radially extending damping device body (123; 223; 323; 423; 523), wherein the damping device body (123; 223; 323; 423; 523) comprises a radially inner circumferential edge portion (124; 224; 324; 424; 524) and a radially outer circumferential edge portion (126; 226; 326; 426; 526), wherein a through hole (136a; 236a; 336a; 436a; 536a) is formed in the damping device body (123; 223; 323; 423; 523), wherein the through hole (136a; 236a; 336a; 436a; 536a) comprises a tapered shape. |
