The effect of ammonia in the fuel on NO/sub x/ emissions was investigated through laboratory experiments and field burner tests. It was found that the degree of conversion of ammonia to NO/sub x/ was a strong function of excess air, ammonia content in the fuel, and of the degree of mixing in the flame. In premixed laboratory flames concentrations of NO/sub x/ above the peak equilibrium amounts were produced. In furnace diffusion flames, the conversion to NO/sub x/ was much less. At substoichiometric air-fuel ratios all the ammonia appears to pyrolize, forming N/sub 2/, and only very little NO/sub x/. Several methods for burning ammonia to produce low NO/sub x/ emission were investigated.
