Abstract：The 2 × 105 m2 sintering machines adopted desulphurization technology of sintering flue gas by limestone-gypsum method. The article introduced the process principle, process flow, design parameters and site layout of the desulphurization installation. By preventing the pipeline from wear, eliminating demister blockage, comprehensive utilization of desulphurization waste water and increasing dedustig efficiency, the system was optimized. The technology is easy to operate and easy maintenance. The synchronous operation rate with 2 × 105 m2 sintering machines reached 96%above. The concentration of SO2 at the outlet was not large than 200 mg/m3 and the dust concentration was not large than 50 mg/m3.
