This paper treats about the problem of nitrogen oxides formation in the process of natural gas combustion. The analysis of the influence of selected combustion parameters on the concentration of NO, N2O and NO2 in the combustion products was done. From many factors determining NOx formation two was selected, ie temperature and residence time at the highest temperature zone, considering them to be particularly important. Detailed analysis of the absolute rate of NOx for various combustion temperatures was done with the use of commercial software CHEMKIN-PRO. Moreover, the paths of formation of above- mentioned compounds were determined. The main goal of the research is to analyze the impact of selected parameters of combustion process, such as temperature, on formation of thermal nitrogen oxides, with special emphasis on the chemistry of the process. The use of numerical methods to predict the products of combustion process, especially NOx, is of great importance in terms of ecological and economical aspects

W niniejszym artykule poruszono problematykę formowania tlenków azotu w procesie spalania gazu ziemnego. Przeanalizowano wpływ wybranych parametrów spalania na udział NO, N2O i NO2 w produktach spalania. Spośród wielu czynników determinujących tworzenie się NOx wybrano dwa, a mianowicie temperaturę i czas przebywania w strefie najwyższych temperatur, uznając je jako szczególnie istotne. Za pomocą komercyjnego oprogramowania CHEMKIN-PRO dokonano szczegółowej analizy absolutnej szybkości NOx dla różnych temperatur spalania. Ponadto, sporządzono ścieżkę formowania ww. związków. Zasadniczym celem badań jest analiza wpływu wybranych parametrów procesu spalania, takich jak temperatura, na formowanie termicznych tlenków azotu, ze szczególnym uwzględnieniem chemii procesu. Wykorzystanie metod numerycznych do przewidywania produktów spalania, m.in. NOx, jest niezwykle istotne w aspekcie ekologicznym i ekonomicznym.
