The paper describes the burning of 21 coals, covering all ranks and under a wide variety of conditions, to ascertain the impact of coal properties on the fate of fuel nitrogen. Fuel NC was identified by using a nitrogen-free oxidant consisting of Ar/O2/CO2. It was found that fuel NO formation depends on the reactivity of volatile nitrogen as well as on total nitrogen content. Internal species concentrations were measured under fuel-rich conditions, and it was found that: (1) the partition of nitrogen between NO, NH3, and HCN was dependent on coal type; and (2) total gas-phase nitrogen species (fuel rich) correlated with exhaust NO (fuel lean). This work will help in the generalization of low NOx burner technology to a wide range of fuels.
