Experimental and Mechanism Studies on a Different‐Velocity Circulating Fluidized Bed for Flue Gas Desulfurization

Abstract

Experimental studies of flue gas desulfurizarion were carneed out in a differentvelociv circulating fluidized bed reactol; using dry slaked lime as the sorbent. SO, removal efficiency could be as greater than 80% when the CdS 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 desulfirization mechanism. The desulfurization reaction occurs quickly in the waterfilm on the surface of the sorbent.
