About this webinar
It is a concern that emissions from coal combustion may pollute the air. A lot of effort has been made to regulate, control and prevent the pollutants emitted from coal-fired power plants. The coal industry is facing increasingly stringent emission regulations, for the release of SO2, NOx, toxic volatile organic compounds, heavy metals, and particulate matter (PM). PM can contain any or all of the aforementioned chemical species or their compounds, plus water and biogenic organic species. PM2.5, as fine PM, can be inhaled into human respiratory systems and travel deep into the lungs causing health problems. PM2.5 is also considered to be a major cause of smog in cities and elsewhere. This webinar describes the international and selected countries’ national air quality and PM emission standards for stationary sources that are relevant to coal-fired power plants. Emission standards for SO2 and NOx are included since they are precursors of secondary fine PM. International and national measurement standards are summarised. Recent developments in PM emission control technologies are reviewed.
