Abstract
The present disclosure provides a gas turbine combustor including a combustion structure () having a combustor liner () and a flow sleeve (). The combustor liner () includes inner and outer surfaces () and defines a combustion zone (). The gas turbine combustor further includes a plurality of hollow airfoil-shaped structures () affixed to the combustor liner () and extending radially outwardly into an airflow space () defined radially between the flow sleeve () and the combustor liner (). Each hollow structure () includes at least one metering tube () providing acoustic communication between the combustion zone () and the hollow structure (). The metering tubes () are detachably coupled to the combustor liner () for permitting interchanging of the metering tube () with at least one additional metering tube having at least one different dimension to effect a change in an acoustic characteristic of the hollow structure ().
