Notes:
Concentrations of NO, NH3, and HCN, together with coal particle burnout and gas composition, were measured during combustion of a bituminous coal. Control of incoming secondary gas swirl level and overall stoichiometric ratio led to significant reductions in nitrogen oxide pollutant concentration. In-situ measurements showed that coal particles were confined near the reactor center during rapid particle reaction. This took place in a locally fuel-rich environment, producing near-quantitative conversion of fuel-nitrogen to NH3 and HCN, with some NO. Subsequent gas phase reactions of these nitrogen species were identified as important in establishing the ultimate NO concentration.
