The article gives results of testing seven coals of varying rank in an experimental mass-burning simulation to assess general nitric oxide (NO) emission characteristics. The fuels were compared to ascertain a relationship between NO emissions, fuel nitrogen content, nitrogen volatility, and firing conditions. Considerable variability in exhaust NO emissions was observed between coal types, even for coals of common rank fired under similar thermal and stoichiometric conditions. Fuel nitrogen conversion to NO was not singularly dependent on inherent nitrogen content or volatility. A correlation was developed to estimate NO emissions based on both coal nitrogen content and char nitrogen fraction for combustion conditions typical of mass-burning stokers.
