A system for controlling combustion dynamics is provided. The system includes a combustor having a combustion chamber and an inlet for feeding a fuel-air mixture into the combustion chamber. The system also includes a dome plate at an upstream end of the combustion chamber. The system further includes a liner along a length of the combustion chamber. The system also includes an actuator configured to control one or more recirculating zones in the combustion chamber.
1. A method of controlling combustion dynamics comprising: providing a flow of premixed fuel and air into a combustor, the combustor comprising: a combustion chamber;an inlet for feeding a fuel-air mixture into the combustion chamber;a fixed dome plate at an upstream end of the combustion chamber; anda liner connected to the fixed dome plate and extending along a length of the combustion chamber;at least one movable dome plate disposed within the combustion chamber and axially movable with respect to the fixed dome plate to control one or more recirculat...
