The aim of the study: to assess the effectiveness of technological measures to manage the risk to public health when exposed to atmospheric emissions of multi-fuel combined heat and power plants (CHP). Methods: The study included the modeling the dispersion of emissions of the studied thermal power plants with the calculation of surface concentrations and assessment of carcinogenic and non-carcinogenic risks to public health, as well as the relative risk of mortality, referrals and hospitalizations according to WHO guidelines on atmospheric air quality. Results: When using low-temperature vortex fuel combustion technology in combination with the modernization of the dust and gas cleaning system, a statistically significant (p0.001) decrease in the value of the carcinogenic risk index is predicted by an average of 80.67%, non-carcinogenic risk by 78.84%, relative mortality risks and referrals to medical organizations by more than 80%. The use of a gas turbine plant allowed to increase the production of electric energy by 72.23%, thermal energy by 4.89%, statistically significantly (p0.001) reduce the level of carcinogenic risk by 44-60%, noncarcinogenic risk by 35-47%, relative risks of mortality, visits to medical organizations and hospitalizations by 33% - 64%. Conclusions: the use of the best available technologies for the modernization of multi-fuel CHP plants, makes it possible to significantly reduce the level of risk to public health while increasing the production of electric and thermal energy, while maintaining the advantage of using both solid and gaseous fuels.
