Method and apparatus for gas turbine engine lean blowout avoidance
Abstract
A method of monitoring and diagnosing the combustion dynamics of a gas turbine engine system is provided. The system includes at least one gas turbine that includes at least one combustor can (26). The method includes receiving a signal (230) indicative of combustion dynamics in at least one of the combustor cans, comparing (202) the received signal to a predetermined lean blowout threshold, and controlling (234, 236) the gas turbine engine system to facilitate reducing a probability of a lean blowout event using the comparison.
