Abstract
At the moment, there is a tendency to increasing the number of thermal power plants (TPPs); this trend can be associated with industrial development and energy consumption growth. This paper discusses the numerical simulation of the pollution movement from activities of the TPP and the study of the pollution concentration level at various distances from the emission source in actual atmospheric conditions. The approbation of the numerical algorithm and the mathematical model was performed using 2D and 3D test problems. The obtained computational values were compared with measured values and computational values of other authors. In addition, the distribution of pollution in the 3D case was investigated on an actual physical size. The Ekibastuz TPP-1 coal-fired power plant was taken as a real example. A distinctive feature of this TPP is that pollution is emitted from two chimneys of different heights (\(H_{H} = 330\) and \(H_{L} = 300\) m). The obtained values illustrated that, due to the difference between the height of the chimney (\(H_{H} - H_{L} = 30\) m), the pollution concentration from the higher chimney (\(H_{H} = 330\) m) was fell down far away from the emission source than from the lower chimney (\(H_{L} = 300\) m) (2160 and 1970 m, respectively). From the obtained data from computation, it can be argued that the construction of higher chimneys reduces the harmful effects of emissions on the environment. Also, the obtained results will help to predict the optimal and safe distance from cities or settlements during the construction of new thermal power plants.
