| Abstract: | The origin,characteristics and its hazards of thermoacoustic instability induced by combustion inside the lean premixed low NOx gas turbines are illustrated.The state of art about the controlling studies on thermoacoustic instability is presented,and discussions are made to address the concepts,applications and features of the passive control and the active control.The underling sole spirit of these controlling methods is consistent with each other,i.e.decoupling the oscillating heat release and the sound field through redesign of the combustor or through introducing outside perturbations. |
