In this work, a computational simulation of the pollutants spread generated during fuel combustion at Ekibastuz SDPP-1 and their chemical reaction in the atmosphere have been presented. Using the example of a real thermal power plant (Ekibastuz SDPP-1), the dispersion NO, NO 2 , CO and products NO 2 , HNO 3 , CO 2 during a chemical reaction with oxygen was modeled. The numerical method was verified by solving three test problems and the received computational solutions were compared with data from the measurement and the computational data of other authors. The purpose of the work was to investigate the pollution level at various ranges from the source. As a result, the mass fraction of the concentration and product during a chemical reaction were determined. According to the obtained data, with increasing distance from the source, the concentration of pollution spreads more widely under the influence of diffusion. The farther the distance from the chimney, the lower the concentration of the substance and products. Thus, the obtained computational values may allow in the future predicting the optimal distance from residential areas for the construction of thermal power plants, at which the concentration of emissions will remain at a safe level.

In this paper, obtained numerical results of the thermal pollution from the operation of a power plant are presented when using the Irtysh River as a natural water cooling system. A two-dimensional formulation by using the "shallow water" approximation is often used as a numerical solution of such problems. For two-dimensional numerical modeling, it is possible to determine the floating flow together with its characteristics of mixing heated water discharge from lateral projections to transverse flow. Furthermore, data from the experiment and numerical values of other authors were used in order to check the conformity of the computational results. The obtained numerical values gave good agreement comparing with data from the experiment, specially the jets trajectory, the recirculation zones size and the dimensionless excess temperature distribution. The obtained data as a result of numerical simulation can be used to study problems associated with the mixing of heated water discharged from the lateral direction into the transverse flow. Also these studies were conducted to study thermal contamination under different scenarios, the impact of heated water discharge from a power plant in the Irtysh River, and the areas of thermal pollution for different velocity scenarios were determined.
