A simple heuristic model is proposed to explain the effect of devolatilization on both coal nitrogen conversion and NO formation. The model is cast into three temperature regimes, the intermediate regime II being initiated at Tk 1100 K. Regime II represents pyrolysis of repolymerized volatiles and t

Experiments on the distribution of fuel nitrogen in pulverized-coal/O2/Ar flames stabilized on a flat-flame burner are reported. The gas-phase concentration of HCN, NO, NH 3, and N 2, and the solid-phase nitrogen content were measured as a function of reaction time. A complete inventory of the major

Analysis of devolatilization of predried large coal particles in fluidized beds requires consideration of both the chemical kinetics of coal decomposition and transport processes. Models available either assume the devolatilization particle to be isothermal (whereas it may be shown that, in general,

## Abstract The physical and chemical characteristics that influence the conversion of fuel nitrogen to nitrogen oxides during coal char combustion were theoretically examined by using a simplified model in which nitric oxide is an intermediate product between fuel nitrogen and N~2~. It was found
