  • System and apparatus for gas turbine engine lean blowout avoidance
    Patent number: 7743599
    Abstract: A method of monitoring and controlling 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. The method includes receiving a signal from a gas turbine engine sensor that is indicative of combustion dynamics in at least one of the combustor cans, processing the received signal to determine a probability of lean blowout for at least one combustor can, and controlling the gas turbine engine system to facilitate reducing a probability of a lean blowout (LBO) event using the determined probability of lean blowout.
    Type: Grant
    Filed: July 17, 2007
    Date of Patent: June 29, 2010
    Assignee: General Electric Company

  • Methods and apparatus for predicting and/or for avoiding lean blow-outs
    Patent number: 7337057
    Abstract: A method for predicting lean blow-outs (LBOs) in a gas turbine engine includes extracting a plurality of tones in pressure signals representative of pressure within monitored combustor cans, tracking a frequency of a hot tone in each monitored can, and utilizing the extracted tones and the tracked frequency to determine a probability of an LBO.

  • SYSTEM AND APPARATUS FOR GAS TURBINE ENGINE LEAN BLOWOUT AVOIDANCE
    Publication number: 20080010966
    Abstract: A gas turbine system is provided. The system includes a gas turbine engine including at least one combustor can, at least one of a combustor dynamics pressure sensor and flame sensor coupled to at least one of the combustor cans, the sensor configured to monitor combustion in each respective can and transmit a signal indicative of combustion in each respective can, and at least one control system configured to receive the signal from said at least one sensor. The control system is programmed to filter the combustion signal to determine the presence of a lean blowout (LBO) precursor, determine a probability of LBO from the filtered signal, and control the gas turbine system to facilitate reducing the probability of LBO.
