New technology helps researchers decrease emissions at coal plants
Beijing: Researchers at Zhejiang University aim to further lower the emissions of coal-fired power plants by improving the ultralow emission technology they have developed.
Their system can effectively reduce the emissions of pollutants such as sulfur dioxide, sulfur trioxide and heavy metals such as mercury.
“We are improving the accuracy of the system, lowering the operating costs under variable load conditions and promoting the system from coal-fired power plants to also be applied to industrial boilers,” said Zhang Yongxin, a researcher at the university’s Institute for Thermal Power Engineering.
Coal is the main source of energy in China. According to the International Energy Agency, the country has been the world’s largest producer of coal since 1985 and produced nearly half the world’s coal in 2014.
Gao Xiang, a researcher at the institute, said coal accounts for over 90 percent of China’s proven reserves of fossil energy resources and, even though new energy is weighing in, its coal-based energy structure is not likely to change in the short term.
