The report gives results of an experimental and analytical investigation of chemical mechanisms involved in the conversion of fuel nitrogen to NOx in combustion. The pyrolysis of fossil fuels and model fuel nitrogen compounds was investigated, droplet and particle combustion models were developed, and premixed flat-flame burner experiments were conducted to study the conversion of HCN and NH3 to NOx in low-pressure CH4-O2-Ar flames. Decomposition rates and products were measured in helium from 850 to 1100C for pyridine, benzonitrile, quinoline, and pyrrole; products were measured for six No. 6 fuel oils, one crude oil, and two coals. HCN was the major nitrogen-containing pyrolysis product: the amount formed increased with temperature. NH3 was a minor product and little if any N2 was formed. The burner experiments demonstrated that fuel NO forms relatively slowly above the luminous zone in the same region where CO is oxidized to CO2 or later. Although HCN and NH3 gave similar yields of NO, the NH3 reacted very early in the flame front; most of the HCN survived the luminous zone and then reacted slowly. A mechanism was proposed in which fuel NO forms via the reaction: O + NCO = NO + CO.
