| Summary: | 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, NO2, CO and products NO2, HNO3, CO2 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. |
