A METHOD ATMOSPHERIC IMPACT ASSESSMENT OF EMISSION SOURCES DURING DIFFERENT FUELS COMBUSTION

Abstract

This study substantiates a new approach to assessing the sources of harmful substances and comparing the scale of their impact on the objects of impact: people, flora, and fauna. The complexity of the problem of air pollution is shown, in particular, the reduction in specific emissions of harmful substances from combustion plants. A new method was proposed for comparing the damage to ambient air quality by the combustion of different types of fuels. A new indicator is proposed to compare the impact of harmful substances during the combustion of different types of fuels on the quality of atmospheric air — the theoretically required volume of clean atmospheric air to dilute concentration of harmful (toxic) substances in combustion products to acceptable atmospheric air standards. The use of methane combustion (as an ideal natural gas) is proposed in accordance with the requirements of EU Directive 2010/75/EU as a unit of scale for determining the dimensionless theoretical volume of clean atmospheric air and dimensionless carbon dioxide emissions. To illustrate the operation of the proposed method for assessing the impact on air, the combustion of different fuels in a new boiler with an electric capacity of 1052 MW (the hard coal fired power plant) was calculated with the specific harmful emissions, which fully complies with EU Directive 2010/75/EU. The proposed method assessment can help in choosing the optimal fuel for any enterprise and in developing standards for emissions of harmful substances. Bibl. 21, Tab. 2, Fig. 1.
