反应作用

Overwet phenomenon, which is found in the DCFBS experimental research was discussed. The effect of overwet on the desulfurization efficiency and on steady operation of the units was analyzed. It is pointed that the overwet zone in the tower is not only the main desulfurization reaction zone, but also the main scaling zone. It plays an important role for the units operating stably with high-efficiency.
