Abstract
A gas turbine flame diagnostic monitor has been described incorporating a plurality of viewing probes to be positioned in a plurality of combustors of a gas turbine and coupled to a plurality of optical fiber image guides for transferring the image from each viewing probe to a video camera. The video camera is coupled to a monitor for displaying the flame received by each combustor probe. A video analyzer generates flame intensity patterns, centroids and second order moments and compares them with predetermined stored flame intensity patterns, centroids and second order moments, and logic for providing diagnostic interpretations of the operation of the gas turbine which is coupled to a turbine controller for controlling the gas turbine to provide balanced combustor operation for optimum temperature of the exhaust gases at the first blade row and to warn station operators of impending problems and shut down the turbine at times when turbine malfunctions are observed. The flame diagnostic monitor overcomes the problem of diagnosing faults in the combustors of gas turbines, and also helps prevent subsequent duct explosions during start up when ignition does not occur in a combustor.
