METHOD FOR DETECTING BURNER FAILURE

Abstract: a method for detecting a burner failure in a gas turbine engine that has a combustor and a turbine disposed downstream of the combustor. the combustor has a plurality of burners arranged annularly. the method includes providing a plurality of temperature sensors arranged annularly at an outlet of the turbine; obtaining a plurality of temperature signals from the plurality of temperature sensors; determining a plurality of validated temperature signals from the plurality of temperature signals; determining a temperature focus at least based on the plurality of validated temperature signals; improving the temperature focus such that the temperature focus is within a tolerance range; and performing at least one hazard protection action at least when the temperature focus crosses a predetermined threshold.
