Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a system and method used in a gas turbine system for adjusting combustion conditions by adjustably attenuating resonance of a flowing fluid thereby helping to increase flammability, improve stability of a flame, reduce emissions, and control combustion dynamics.SOLUTION: A system 11 includes a combustor 12 having a combustion chamber 17 and a combustor supply passage configured to supply a fluid flow into the combustion chamber 17. The system 11 also includes a resonator 13 configured to receive at least a portion of the fluid flow. The resonator 13 comprises a frequency adjuster configured to change an attenuation frequency of the resonator 13.SELECTED DRAWING: Figure 1 【課題】ガスタービンシステムにおいて、流動流体の共振を調節可能に減衰させることで燃焼状態を調節し、それによって可燃性を高め、火炎の安定性を改善し、排出物を低減し、かつ燃焼ダイナミクスを制御することを支援するシステムおよび方法を提供する。【解決手段】システム１１は、燃焼室１７と燃焼室１７への流体流れを供給するように構成された燃焼器供給通路とを有する燃焼器１２を含む。システム１１は、流体流れの少なくとも一部分を受け取るように構成された共振器１３も含む。共振器１３は、共振器１３の減衰周波数を変化させるように構成された周波数調節器を備える。【選択図】図１
