Natural gas combustion was carried out in air enriched with oxygen in the amount of 25 and 29% with addition of CO₂ in place of part of nitrogen. The research was carried out at different flow rates of gas and oxygen excess ratios. The concentration of CO and NOx was analyzed. It has not been proved that the increased oxygen concentration influences significantly the CO concentration. However, the addition of CO₂ caused a substantial variability of CO concentration in the exhaust gas, in contrast to the concentration of NO_x which decreased monotonically. Model calculations, performed with use of FactSage, indicate an increase in the concentration of CO not only for the air enriched with oxygen, but after adding CO₂ too, as well.

Przeprowadzono spalanie gazu ziemnego w powietrzu wzbogaconym w tlen w ilości 25 i 29% z dodatkiem CO₂ w miejsce części azotu. Badania prowadzono przy różnych przepływach gazu i współczynnikach nadmiaru tlenu. Analizowano stężenie CO oraz NO_x. Nie stwierdzono, by zwiększone stężenie tlenu wpłynęło w sposób znaczący na stężenie CO. Natomiast dodatek CO₂ spowodował znaczną zmienność stężenia CO w spalinach, w przeciwieństwie do stężenia NO_x, które spadało monotonicznie. Obliczenia modelowe, przeprowadzone przy pomocy FactSage, wskazują na wzrost stężenia CO nie tylko dla powietrza wzbogaconego w tlen, ale także po dodaniu CO₂.
