Abstract
With the domestic steel production capacity gradually expanded, iron and steel enterprises have become one of largest source of SO2 emissions. And the sintering process can produce lots of SO2. According to review itself characteristics and the experience of the domestic and foreign desulfurization, the LSJ-FGD flue gas desulfurization process was chosen which is one way of circulating fluidized bed desulfurization. The principles, processes and system configuration of desulfurization systems as well as the matching operation with the main exhaust fan were introduced. Up to now, the process of desulfurization system had been operating stably. And the synchronous operation rate and average desulfurization rate were better than 90%. At the same time, the dust emission concentrations was less than 20 mg/m3.
