Abstract:

Purpose. Analysing the current state of sulfur dioxide and dust emissions from coal combustion at thermal power plants of Ukraine, predicting them with regard to changes which have occurred in the Ukrainian power industry over the last years, and estimating these emissions to compare with the limit gross emission values of pollutants according to the National Emissions Reduction Plan.

Methodology. The method for calculating the pollutant emissions is elaborated, based on using the quantity of produced or supplied electricity for each year of TPP operation.

Findings. It has been established that the gross emissions of SO₂ at Ukrainian TPPs over the last years have amounted to about 620 thousand tons, and those of dust have made 140 thousand tons. In 2019, the average emission factors for all types of coal were 1180 g/GJ (for sulfur dioxide) and 288 g/GJ (for dust). The average values of specific emissions of SO₂ and dust were 14.4 and 3.4g/kWh of supplied electricity, respectively, as compared with 1.2 and 0.2 g/kWh, which are characteristic of the current level at coal TPPs of the EU countries.

Originality. Analytic dependency has been established between SO₂ emission factors in flue gas at coal TPPs and low heat value and sulfur and ash content for Ukrainian energy coal.

Practical value. The developed method allows one to perform calculations of maximum permissible and predicted gross emissions of SO₂ and dust at TPPs of Ukraine.

Keywords: thermal power plant, electricity, flue gasses, sulfur dioxide, dust, emission limit values
