Abstract
A dampener or resonator is provided within a combustor casing to mitigate combustion dynamics. The combustor casing head end volume is reduced by the resonator to mitigate combustion dynamics. The resonator is formed by a ring shaped plate that carries a continuous inwardly protruding wall or segmented inwardly protruding wall portions. The resonator can be a stand alone part that is inserted into the combustor casing or it can be integrally formed with the combustor casing.
