| description | The invention discloses a structure and method for restraining thermoacoustic oscillation of a gas turbine combustor, and relates to the field of restraining thermoacoustic oscillation of the gas turbine combustor. The structure comprises an outer layer pipeline and an inner layer ring pipe located in the outer layer pipeline, and the length of the inner layer ring pipe is one fourth of the wavelength of sound waves; a resonant cavity is formed between the outer-layer pipeline and the inner-layer annular pipe, one end of the resonant cavity is an annular cavity opening used for sound waves to enter and exit, and the other end of the resonant cavity is provided with a connecting ring used for connecting the outer-layer pipeline and the inner-layer annular pipe. Thermoacoustic oscillation of the combustor of the gas turbine can be effectively restrained, and the influence generated by the thermoacoustic oscillation is reduced.
