| Abstract |
The report gives results of an investigation of the effect of fuel sulfur compounds on nitrogen oxides (NOx) emissions from premixed gaseous flames. Laboratory measurements, using a methane/air flat flame doped with SO2 or H2S, showed that fuel sulfur inhibits the formation of NOx arising from thermal fixation. This inhibition was significant at all air/fuel ratios and especially at high air preheats. The effect of fuel sulfur on formation of NOx arising from fuel nitrogen oxidation is less clear because of complex reactions between sulfur- and nitrogen-containing species in both the flame and the sampling probe. A mathematical simulation of a flat flame was developed that showed that the observed effect of fuel sulfur on 'thermal NO' could be explained by a kinetic mechanism involving the catalysis of atom recombination reactions by SO2. The experimental and theoretical results may be especially significant from a practical point of view, since they appear to indicate that fuel desulfurization may lead to increased NOx emissions. |
