In a significant step toward improving air quality, the Ministry of Science and Technology has partnered with Hubei China Steel Tiancheng Environmental Protection Technology Co., Ltd. to advance a key initiative under the "12th Five-Year Plan." The project, titled "Iron and Steel Furnace Dust PM2.5 Control Technology and Equipment," is now being led by China Steel Tiancheng, with collaboration from Northeastern University, Tsinghua University, and Panzhihua Iron and Steel Group's Chengdu Steel Vanadium Co., Ltd.
The goal of this 863 Project is to develop advanced technologies and equipment capable of efficiently capturing PM2.5 particles emitted from steel furnace processes. This includes improving high-efficiency dust-trapping methods, creating integrated systems with independent intellectual property rights, and introducing fine filter materials and intelligent control technologies. These innovations aim to significantly reduce fine particulate and total dust emissions from industrial kilns, contributing to better urban and regional air quality across China.
PM2.5 pollution has become a major environmental challenge in recent years, affecting public health, living standards, and overall air quality. Alongside other pollutants like NOx and nitrogen oxides, it contributes to haze formation, especially in densely populated and industrialized areas. The primary sources of PM2.5 include emissions from steelmaking, coal mining, power generation, and vehicle exhaust, with heavy industries being the main contributors.
During the "Twelfth Five-Year Plan" period, the Ministry of Science and Technology launched several projects targeting pollution reduction in key sectors. Among these, the PM2.5 control project in metallurgical kilns stands out as particularly challenging due to the high volume of smoke, fine dust, and high-temperature flue gases involved. Addressing these issues requires cutting-edge technological solutions that can meet increasingly stringent environmental regulations.
According to Li Ning, head of the China Steel Tiancheng Technology Center, the growing emphasis on environmental protection and stricter emission standards are pushing metallurgical companies to invest in new technologies. He estimates that the annual demand for dust removal equipment in the steel industry could reach approximately 4 billion yuan in the coming decade, highlighting the scale and importance of this development. This initiative not only addresses current environmental concerns but also positions China’s steel industry for sustainable growth in the future.
