Optimization Practice of Wet Desulfurization Process Parameters for Vanadium Titanium bearing iron ore Sintering

In order to address the problems occurred during the wet desulfurization process for sintering vanadium titanium bearing iron ore,some measures had been taken,such as dismounting all flue gas bypass ducts,optimizing individual system operating parameters and Ca/S molar ratio,reducing the failure rate of mist eliminator,and improving the quality of gypsum byproduct,under which the synchronous operation rate between the sintering machine and desulfurization systems reached 100%,and Ca/S molar ratio decreased by 0.18,emissions compliance rate of sulfur dioxide in the outlet flue gas increased by 5.5%.Limestone-gypsum wet flue gas desulfurization has been proven a suitable technology for vanadium titanium bearing iron ore sintering process.
