We have been performing research at BYU on the generation of soot from coal
since 1991. Soot is thought to be a mode of heat transfer away from flames,
and hence may influence local gas temperatures near burners. The temperature
in turn influences pollutant formation. In addition, some nitrogen is included
in soot, and hence this pathway should be considered in nitrogen pollutant calculations.
