The factors that influence the conversion of fuel nitrogen in coal to nitrogen oxides during combustion were experimentally investigated using a unique combustion facility that is described in detail. The tests reported constitute a prelude to an in-depth investigation on the optimum staged combustion or pulverized coal, and employed the substitution of argon for molecular nitrogen to isolate fuel originating nitrogen oxide emissions. It was found that under practical combustion conditions fuel nitrogen conversion constituted by far the major portion of total NO/sub x/ emissions, and was only a weak function of temperature over a wide temperature range. Radical increases in fuel nitrogen conversion were, however, obtained under conditions of extremely high temperatures or under conditions where coal ignition was delayed. These phenomena are of practical interest since they indicate how both fuel composition and generalized combustion parameters are likely to affect total NO/sub x/ emissions from pulverized coal.
