Flame characteristics and emissions of NO/sub x/ were measured for four different industrial burners in two test furnaces for firing rates between 0.5 and 10 /times/ 10/sup 6/ Btu and furnace temperature between 2000 and 2700/degree/F. Both natural gas and No. 6 fuel oil were used. Oxygen concentration of enriched air was varied from 21 to 100%. NO/sub x/ emissions with natural gas increased sharply from 0.1 to over 1.85 lb/10/sup 6/ Btu at a constant furnace temperature was raised from 2000 to 2700/degree/F the NO/sub x/ emissions at 35% O/sub 2/ rose about 24%. NO/sub x/ emissions diminished with increasing oxygen concentration above 50% O/sub 2/ for two oxy-fuel burners due to the rate controlling effect of nitrogen concentration. NO/sub x/ emissions of 0.36 to 0.48 lb/10/sup 6/ BTU were observed for a high flame temperature oxy-fuel burner at 90 to 100% Btu O/sub 2/ and 2000-2700/degree/F furnace temperatures. NO/sub x/ concentration as low as 0.01 lb/10/sup 6/ Btu was measured for a low flame temperature oxy-fuel burner at 100% O/sub 2/ and 2000/degree/F furnace temperature. No/sub x/ emissions with No. 6 fuel oil containing 0.54% nitrogen were measured for an air burner and an oxy-fuel burner at 2000/degree/F. Relatively small effect on NO/sub x/ emission was observed for the air burner. 12 refs., 11 figs. , 1 tab.
