摘要： The present disclosure provides a gas turbine combustor including a combustion structure (10) having a combustor liner (14) and a flow sleeve (12). The combustor liner (14) includes inner and outer surfaces (31, 30) and defines a combustion zone (15). The gas turbine combustor further includes a plurality of hollow airfoil-shaped structures (22) affixed to the combustor liner (14) and extending radially outwardly into an airflow space (18) defined radially between the flow sleeve (12) and the combustor liner (14). Each hollow structure (22) includes at least one metering tube (26) providing acoustic communication between the combustion zone (15) and the hollow structure (22). The metering tubes (26) are detachably coupled to the combustor liner (14) for permitting interchanging of the metering tube (26) 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 (22).

摘要： A combustion chamber (10, 20) for a gas turbine (1) with at least two combustion zones (23, 24) and at least one burner arrangement (11, 28) for the combustion of a fuel/air mixture in the combustion zones (23, 24). The burner arrangement (11, 28) has at least one premixing passage (29) that opens into the combustion zones (23, 24) to provide a fuel/air mixture, and an air supply (32) and at least one fuel supply (33) encompassed in the burner arrangement (11, 28) and open into the premixing passage (29). The combustion chamber permits a particularly effective damping of combustion chamber pressure fluctuations. To this end, the air supply (32) is designed in a stepped manner such that the outlet openings (34, 34a, 34b, 34c) of the stepped air supply that open into the premixing passage can be assigned different delay times (τ1, τ2, τ3), which damps the fluctuations.

摘要： A combustion chamber (10, 20) for a gas turbine (1) having a housing (12, 23), a combustion zone (21, 22, 47) surrounded by the housing (12, 23), and at least one burner arrangement (11, 25), which has at least one pre-mixing passage (28) opening into the combustion zone (21, 22) for preparation of a fuel/air mixture. To enable suppression of combustion chamber pressure fluctuations, at least one interference body (50) is provided against which a flow can take place and to which a Strouhal number can be assigned, the flow generating fluidically induced sound waves. The interference body (50) is in a passage (48, 59) opening into the combustion zone (21, 22, 47). A fluid (51, 62) flowing through the passage (48, 59) in the direction of the combustion zone generates a sound wave with a frequency f by flowing against the interference body (50), wherein the frequency f substantially corresponds to a dominant frequency of the combustion chamber.
