A Numerical Study for the Assessment of Air Pollutant Dispersion with Chemical Reactions from a Thermal Power Plant

A numerical 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 and product CO2 during a chemical reaction with oxygen was modeled. The numerical method was verified by solving three test problem and the obtained numerical solutions were compared with data from the experiment and the numerical data of other authors. The purpose of this work was to study the level of pollution at various distances 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.
