Combustion in a gas turbine is controlled through use of flame spectroscopy in order to achieve low NOx emissions in the exhaust. By detecting and monitoring the combustion flame in the turbine to determine intensity of ultraviolet spectral lines, and dynamically adjusting the fuel/air ratio of the fuel mixture such that this intensity remains below a predetermined level associated with a desired low level of NOx emissions, the engine produces significantly reduced NOx emissions in its exhaust but at a sufficiently high combustion flame temperature to avoid any undue risk of flame-out, thereby assuring stable, safe and reliable operation.
