This paper presents the findings of experimental investigations into the combustion of H₂/NG and NH₃/NG blends at a pilot scale of 75 kW, in conjunction with a pilot-scale CO₂ absorption process. It has been demonstrated that the existing pilot-scale natural gas burner can effectively achieve stable combustion of NG/H₂/NH₃ blends containing up to 10 vol% each of H₂ and NH₃. The study found a clear and significant increase in NO_x emissions (up to 3350 ppm) resulting from the addition of ammonia to the fuel mixture. The implementation of air staging has been shown to substantially reduce NO_x emissions, with documented decreases ranging from 80% to 90% at 282 ppm.
