| Abstract |
The paper gives results of burning petroleum-, coal-, and shale-derived liquid fuels in a downfired tunnel furnace to assess the impact of fuel properties on the formation and control of NOx emissions. A nitrogen-free oxidant mixture (Ar, CO2, O2) was used to isolate fuel NOx formation. Under excess air conditions, fuel NOx correlated well with total fuel nitrogen content for both the petroleum and alternate fuels. Under staged combustion conditions, the influence of fuel nitrogen content was much less pronounced but equally highly correlated except for coal-derived liquid. Exhaust NOx emissions were directly related to the amount of oxidizable nitrogen species leaving the first stage. NO, HCN, and NH3 concentrations were measured in the fuel-rich zone of the staged combustor as a function of stoichiometry for seven liquid fuels and one CH4/NH3 mixture. Similar characteristics were observed for all liquid fuels. As the first stage stoichiometry (SR1) was reduced, NO concentrations at the first stage exit decreased; however, below SR1 = 0.8, HCN and NH3 concentrations increased. Thus, the total fixed nitrogen (TFN = NO + HCN + NH3) concentration passed through a minimum. Experimental data also indicated that increasing the temperature of the fuel-rich zone decreased TFN concentration which resulted in reduced exhaust NOx emissions. |

Similar characteristics were observed for all liquid fuels. As the first stage stoichiometry (SRI) was reduced, NO concentrations at the first stage decreased; however, below SRI=0.8, HCN and NH3 concentrations increased. Thus, the total fixed nitrogen (TFN=NO+HCN+NH3) concentration passed through a minimum.
