Due to the fact that the operation of power plants is based on the General combustion processes of organic fuel, in accordance with modern requirements, a special place is taken by monitoring the release of harmful emissions and flue gases into the atmosphere. Currently great importance is the study of the prevalence of harmful nitrogen compounds at high temperatures and their formation mechanisms in the combustion process. In this regard, during the operation mode of any power facility, it is necessary to control the release of such gaseous harmful substances. Among the harmful ones is the most important problem of the formation of nitrogen particles that have a negative impact on the environment and human health, and in what quantities it is released into the atmosphere. The paper summarizes information about the regularities and mechanisms of formation of nitrogen substances in the combustion chamber space of a real energy object, as well as about the propagation in the chamber space obtained as a result of digital experiments. The results of a quantitative study of the distribution of the concentration of nitrogen oxides at high temperatures in the combustion chamber of the boiler are presented.
