Experimental studies of flue gas desulfurization were carried out in a different‐velocity circulating fluidized bed reactor, using dry slaked lime as the sorbent. S0 2 removal efficiency could be as greater than 80% when the Ca/S molar ratio was 1.1, and when a small amount of water was added into the process. By considering the main aspects that influence desulfurization efficiency in the experiment, it was found that the water sprayed into the reactor plays an important role. In addition, a preliminary investigation was performed on the desulfurization mechanism. The desulfurization reaction occurs quickly in the water film on the surface of the sorbent.
