Based on its own characteristics and combined with the experience of desulfurization, Baosteel No. 3 Sinter Plant has independently developed the gas spout-swriling limestonegypsum desulfurization technology, which includes processes, controls and equipments. The theory, process and control of the sintering desulfurization systems are described in this study. Through process monitoring, control and adjustment of operating parameters, the new desulfurization system fit in with the original sintering system.
