Recent regulation on NOx emission is promoting the use of lean premix combustion for the high temperature gas turbines. But, premix operational experience has been accompanied by combustion oscillation. This paper describes the characteristics of reducing the combustion oscillations in premix combustor which are simulate combustion conditions of can type gas turbine combustor. The resonators were applied for reducing the combustion oscillations. The results showed that the resonator could achieve larsre reduction of the combustion oscillation levels.
