An experimental study has been performed on flue gas desulfurization (FGD) by flowing bed. This paper presents the relationship between desulfurization efficiency and the parameters of temperature and absolute humidity and fly ash. The study of reaction between the sorbents with SO 2 has been performed from 65 ℃ to 130 ℃, and the humidity is changed by adjusting the flow rate of the steam from 0% to 10%. In addition, the fly ash is added to simulate the recycle of fly ash, the ratios of fly ash to calcium are 1∶3, 1∶5, 1∶8 respectively. The experiment results indicate that temperature doesn’t have a strong effect upon desulfurization efficiency without water vapor, and the highest efficiency is achieved when temperature of flue gas is 68 ℃ or so with water vapor; and T =65 ℃, reaction shows the best result when absolute humidity is 7.3%; as for the influence of fly ash, when T =68 ℃, Ca/S=1.2, comparing with CaO, the efficiency increases 12 8% by the sorbent of 1∶8 (CaO to fly ash).
