| Abstract: | This paper presents mechanism and factors of semi-dry flue gas desulfurization, and solutions to the problems, and the effects of parameter on SO2 removal are investigated, such as Ca/S molar rate, approach to saturation temperature, spout water, flue gas moisture, limestone particle diameter, SO2 inlet consternation and ash recycle. And then, using hop-pocket to assist removing SO2 is also introduced. Aiming at problems that semi-dry SO2 sorbent efficiency is lower and Ca/S molar rate is high, the paper gives several technologies about advancing SO2 sorbent efficiency, in order to improve semi-dry flue gas desulfurization. |
