Abstract In this article, a study of the processes of heat and mass transfer in high-temperature and thermochemically activated reacting flows in a real physicochemical system (turbulent flows with physicochemical transformations in combustion chambers) in three-dimensional geometry using numerical methods was carried out. As a result of computational experiments vector distribution full velocity, temperature fields, fields of concentrations of nitrogen oxides NO over the entire volume of the combustion chamber were obtained and a comparative analysis was carried out for the two boilers. The results obtained allow us to conclude that the use of plasma preparation of a pulverized coal torch for combustion has a positive effect on the process of heat and mass transfer and allows minimizing emissions of harmful substances.
