Experimental studies are carried out with medium hot-state facility of flue gas desulfuriztion of circulating fluidized bed. Based on the experimental results, mass balance and the chemical reactions taken place in the reactor, a mathematical model of desulfurization efficiency in CFB-FGD system is established. The relationship between the ratio K_<ca(oh)2> of hydrated lime reacted with SO_2 and the difference of dew point and the temperature of the flue gas is given by combination of the experimental results and the mathematical model. The calculating and experimental results show that the model can be used to give better prediction for removal efficiency of the CFB-FGD system. The results also demonstrate that main factors on removal efficiency are the temperature of the reactor, ratio of Ca/S, and the concentration of the circulating materials. On the basis of the calculating results, it is recommended for the concentration of circulating material to be selected as range between 800-1200 g.m^<-3>
