Abstract:: To date, limestone-gypsum has been the most widely used sintering flue gas desulfurization technology in China's steel industry. In order to demonstrate the application status, this paper stated the current desulfurization situation of Baosteel, Meishan Steel, Xiangtan Steel, Zhang steel. Process of limestone-gypsum obtained in these steel companies is playing an increasingly important role in sintering flue gas desulfurization, and a majority of these plants get a high desulfurization rate at more than 90%, which makes great contribution to the work of sulfur dioxide emissions. Besides, some problems of the desulfurization process in these plants are discussed and solutions are put forward to promote further development of the technology. For the prospects of the technology, it has been an inevitable trend to develop integration technology of desulfurization, denitrification and dioxin removal to meet requirements for energy saving work during the Twelfth Five-Year Plan. All these above presented in the paper will provide a basis in reality for the further development of this technology.
