This paper describes results of experiments on combustion control systems for the suppression of combustion oscillation. Considering the thermo acoustic effect, secondary injection system was applied to reduce the pressure oscillation and combustion noise. In this study, both fuel and air injection systems as the secondary injection were carried out As the results, in the case of fuel injection, the main flame was anchored with lift-off and then the pressure oscillation was suppressed. However, NOx level was increased. In the case of air injection type, both the pressure oscillation and the NOx level were decreased. Furthermore, it was found that flame-holding technique with the super-lean combustion could be established using the secondary air injection system.
