Dense medium cyclone technology to improve quality of coal

摘要

Coal-fired plant pollution is due to the release into the atmosphere of the hot flue gasses produced from the combustion of coal. Dust from power plants has been linked to cancers, while SO2 and NOx have both been identified as acid rain precursors. NOx has also been associated with the production of photochemical smog. Various pollutant control systems have been developed over the past several decades and are continually evolving. However, even with these systems in place, coal-fired plants still produce significant levels of emissions, and certainly carry this stigma with them.
