Air Pollutant Emissions from Coal-Fired Power Plants
Abstract: 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 emissions indicate that the construction of flue gas denitrition systems is necessary. PM emissions varied from 2.3 kg to 299.9 kg per hour. Total sulfur, moisture, ash and volatile content, and net caloric value of coals were investigated to elucidate the relationship between coals and air pollutant emissions.
