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.

本文对DCFBS实验研究中发现的反应塔内的过湿现象，进行了分析与讨论，并研究了过湿现象对脱硫装置的脱硫效率和稳定运行的影响，指出脱硫塔内过湿区既是脱硫反应的主反应区，也是主要的结垢区，它对脱硫装置稳定高效运行起着重要作用。

At first a the fundamental experimental research has been performed, such as resistance performance of system, the effect of Ca/S mole ratio, approach to saturation temperature , SO〓 inlet density, the flow rate and humidity of flue gas on the desulfurization efficiency, and then the studies on high-rate circulation of solid particles in the desulfurized tower were done, overwet phenomenon were analyzed; the study on carbide slag desulfurization and scaling in the tower has been performed in detail.
