چکیده
Purpose. Development and verification of a method for calculating forecasting CO2 emissions from coal combustion at thermal power plants based on proximate analysis data. Calculation gross specific per unit output energy mass consumed Ukrainian (TPPs). Methodology. Methods mathematical statistics were used processing the data ultimate 170samples A, L, G, LFG ranks with low heat value operating state in range 17.2 to 31.0 MJ/kg ash content dry (Ad) 3.8 38.0% determine relationships between carbon emission factors (kc), calorific value, content. Findings. The values mixtures coals grades A G TPPs 20172021 calculated. For 2021, average was 94,128 g/GJ, L it 104,987 g/GJ. Gross have been 3849million tons recent years, their annual reduction is due decrease production fuel consumption TPPs, primarily L. Originality. Empirical dependencies kc steam different are determined form coefficients a, b, c mixtures. relationship linear: where K coefficient depending grade. LFG. Practical value. Verification created shows that calculation error less than 1.0%. This line requirements Monitoring Procedure Directive 2003/87/EC. In Ukraine 1,084 g/kWh all coal. 1.94 t/t grades, 1.91 LFG, 2.21 official reports Ministry Energy contain information amount produced electricity, coal, forecast balances electricity therefore, established by us convenient use estimating dioxide emissions.

Emissions of sulfur trioxide from coal-fired power plants.
Emissions of sulfur trioxide (SO3) are a key component of plume opacity and acid deposition. Consequently, these emissions need to be low enough to not cause opacity violations and acid deposition. Generally, a small fraction of sulfur (S) in coal is converted to SO3 in coal-fired combustion devices such as electric utility boilers. The emissions of SO3 from such a boiler depend on coal S conte...
متن کاملAir Pollutant Emissions from Coal-fired Power Plants. 2.
In order to investigate the factual air pollutant emissions from Henan’s power sector in 2010, SO2, NOx and PM emissions from 24 generating sets from 15 coal-fired power plants have been measured. It is shown that SO2 emission values from 22 of 24 generating sets conform to the requirements, which is causing by the high performance of the flue gas desulfurization system. Much higher NOx emissio...
متن کاملEstimates of Emissions from Coal Fired Thermal Power Plants in India
Coal is the primary fuel for electricity generation in India and its usage is continuously increasing to meet the energy demands of the country. This paper presents emissions of carbon dioxide (CO2), sulfur dioxide (SO2), and nitric oxide (NO) from thermal power plants in India for a period of nine years from 2001-02 to 2009-10. The emission estimates are based on a model in which the mass emis...
