Abstract

A system for reducing combustion dynamics in a combustor (10) includes an end cap (28) that extends radially across the combustor (10) and includes an upstream surface axially separated from a downstream surface. A combustion chamber (26) is downstream of the end cap (28), and tubes (24) extend from the upstream surface through the downstream surface. Each tube (24) provides fluid communication through the end cap (28) to the combustion chamber (26). The system further includes means for reducing combustion dynamics in the combustor (10). A method for reducing combustion dynamics in a combustor (10) includes flowing a working fluid through tubes (24) that extend axially through an end cap (28) that extends radially across the combustor (10) and obstructing at least a portion of the working fluid flowing through a first set of the tubes.
