Development and applications of Baosteel 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.
