recirculation (EGR) ratios, equivalence ratios and boiler capacities on thermal efficiency, NOx and CO emissions and the flame … when EGR was used, the NOx and CO concentrations decreased and the thermal efficiency increased. In the case of a 15% EGR … of the boiler, and the thermal efficiency was approximately 4.7% higher. However, unlike NOx concentrations, although the …
