| 摘要 |
Vibrations generated by the reaction dynamics in a gas turbine combustion chamber (11) are modulated to reduce or nullify troublesome vibrations by using a gas flow restrictor (20) which has one or more restrictor holes (21, 121) and is positioned in a fuel gas passage (16) upstream of a fuel gas injector (17). The restrictor may be in the form of a disc (320) having a co-axial tubular member (23). |
