The article presents an analysis of the structure of pollutant emissions from boiler units of a coal-fired combined heat and power plant using the example of CHPP-1 in the city of Semey. The study is based on operational and inventory data for 2024, reflecting the actual operating conditions of the equipment. Quantitative characteristics of emissions of major pollutants and their distribution between steam and hot water boilers were determined. The analysis showed that gaseous pollutants dominate the structure of emissions – nitrogen dioxide, sulfur dioxide, carbon monoxide, and nitric oxide – with a total share exceeding 95% of the annual emissions. Among solid pollutants, the largest share belongs to inorganic dust with a high content of silicon dioxide, while the contribution of other substances remains insignificant. The quantitative assessment of the emission structure made it possible to determine the actual contribution of each type of equipment to the total level of air pollution. The findings provide a basis for designing targeted strategies to reduce air pollution at thermal power plants, optimize environmental monitoring systems and improve the performance of flue gas cleaning equipment, thereby supporting the sustainable operation of energy facilities.
