Show computational tool that we presented in that paper, when coupled with our experimental set up, makes us particularly well armed to deal with these questions. Some good results are presented on figure 9. It showes few points of very low NOx level obtained with burners developed at the AIR LIQUIDE Research center under pure 02 combustion conditions. An AIR LIQUIDE patent for such a burner is pending today. In conclusion, one can state that pure oxygen technics present a deep interest in dealing with air pollution, especially for NOx emissions. Such technics need to be perfectly mastered for reliability and efficiency reasons and we are working on. The model described in this paper is one of our last accomplishment and is today very useful. -----------*---------- Bibliography [1] Directive du conseil 88/609/CEE , JO nOL 306 du 7-12-88, p 1-13 ( French translation of the CEE directive for the large combustion plants ) [2] D.
