Abstract

Experimental and theoretical investigation of prompt nitrogen oxides emission in flame of different gaseous fuels were carried out with purpose of minimizing total NOx yield. The effect of the following factors was determined: air excess from 0.3 to 1.1, flame temperature, heating flame rate, fuel content. It was found that, if air excess was less than 0.65, some prompt NOx converted to N2 in consequence of reacting with hydrocarbon radicals.
