摘要： PROBLEM TO BE SOLVED: To provide a gas turbine combustor capable of reducing combustion vibration irrespective of the frequency range so as to consistently realize low NOx.
SOLUTION: The combustor 3 has a first box body 30 disposed adjacent to a resonator 20 to form a first internal space 31 in which the resonator having a cavity 21 is annularly fitted to the outer circumference and sound absorption holes 22 opened in the cavity 21 are formed, and a first throat 32 in which one end 32a is opened in the cavity 21 and the other end 32b is opened in the first internal space 31 on an outer cylinder 6 having a combustion area F inside. Fluid particles which are vibrational elements in the high frequency range of the combustion vibration produced in the combustion area F are vibrated through the sound absorbing holes 22 in resonance with air in the cavity 21 of the resonator 20. Fluid particles which are vibrational elements in the low frequency range of the combustion vibration are vibrated through the sound absorption holes in resonance with air in the first internal space 31 through the cavity 21 and the first throat 32, and the amplitude thereof is damped.
