This paper presents a comparative analysis of the kinetic schemes with the numerical analysis of the generation of nitrogen oxides during the combustion of the pulverized fuel. The distributions of the concentration of nitrogen oxides of two studied kinetic schemes with height of the combustion chamber are obtained. The conclusions about the accuracy of numerical researches and the choice of optimal kinetic scheme are made.
