Because a lot of steel slag containing alkaline substances, has a desulfurization potential. To this end, the issues about using steel slag as a desulfurization agent for flue gas desulfurization to achieve by Waste. Taking steel slag from a steel plant as the absorbent, to self-bubbling device as absorbers, an experimental study on FGD with steel slag was conducted. it was studied the size of steel slag, serous concentration, the concentration of SO2 in the air, pH value and Flue gas flow on steel works dust wet desulfurization rate,analyzing the composition of steel slag and response mechanism ,. The results showed that, when the control section conditions: size of the steel slag is greater than 100 mesh , serous concentration is greater than 1%, the concentration of SO2 in the air less than 1500ppm, Flue gas flow is less than 0.09m3/h,pH6,The sulfur dioxide removal efficiency can reach 80%, to reach a comprehensive way, to the effect of waste by waste.
