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.

在这项工作中，对Ekibastuz SDPP-1燃料燃烧过程中产生的污染物扩散及其在大气中的化学反应进行了计算模拟。以实际火力发电厂（Ekibastuz SDPP -1）为例，分散液NO，NO ₂，CO和产物NO ₂，HNO ₃，CO ₂在与氧气发生化学反应期间进行了建模。通过解决三个测试问题验证了该数值方法，并将接收到的计算解决方案与来自测量的数据和其他作者的计算数据进行了比较。这项工作的目的是从源头上调查各种范围的污染水平。结果，确定了化学反应过程中浓度和产物的质量分数。根据获得的数据，随着与污染源距离的增加，污染物的浓度在扩散的影响下分布更加广泛。与烟囱的距离越远，物质和产品的浓度就越低。从而，
