Application of gaus mathematical model in determination of ground concentration and distribution of sumpor dioxide before and after desulphurisation of chimney in the thermal power plant Kostolac B

The most widespread and harmful pollutant for human health is sulphur dioxide. Coal power plants are the main pollutants of sulphur dioxide. According to the Climate Action Network (CAN), the largest sulphur dioxide pollutant in Europe is the Kostolac B thermal power plant from Serbia, which in 2016 emitted 128,000 tonnes of SO2 into the atmosphere. For these reasons, the Power Company of Serbia completed the flue gas desulphurisation plant in Kostolac B TPP in 2017, which reduces sulphur dioxide emissions. The paper analyzes the impact of different scenarios (before and after the construction of the desulphurisation plant) of sulphur dioxide emissions from TPP Kostolac B using a Gaussian dispersion model. Ground concentrations of SO2 at different distances from the thermal power plant were calculated. Based on this, the results of the flue gas dispersion and the distribution of ground concentrations of SO2 are presented in the paper
