Combustion dynamics monitoring

摘要

A method for monitoring combustion dynamics of a can annular combustor ( 12 ) of a gas turbine engine includes monitoring respective dynamic operating conditions of cans ( 16 ) of the can annular combustor with respective dynamic operating condition sensors ( 20 ) associated with each of the cans. The method also includes grouping the cans into two or more groups according to their respective dynamic operating conditions and identifying a sensor providing an anomalous dynamic operating condition reading for at least one of the cans. The method further includes determining a need to service the identified sensor according to the associated can's group membership.
