Development and Applications of Baosteel's Sintering Flue Gas Desulphurization Technology

The characteristics of sintering flue gas, the research background of the BSFGD （Swirl-Jet-Absorbing Wet Limestone-gypsum Sintering FGD Technology ） developed by Baosteel, and technical features of its process and equipments are introduced in detail. The BSFGD＇ s main contents, achievements in pilot experiments, and applications in engineering projects are analyzed and discussed systematically in this paper. The past practice and experience proved that this technology has a strong adaptability to such an environment where the sintering flue gas temperature, SO2 concentration and the flue gas volume fluctuate intensively. As this technology features a high pollutant-removal efficiency, excellent technical and economic performance, stable and reliable operation and recoverable by-product （gypsum） , etc. , it has a wide range of applications in flue gas desulphurization for large and medium-sized sintering machines in the steel industry.
