| Abstract: | The principle, advantages and research developments of the semi-dry flue gas desulfurization by pow- der-particle spouted bed （PPSB） are introduced. The kinds of absorbent particles, diameter of absorbent particles, Ca/S, as well as operating parameters, such as residence time of gas, temperature of gas, bed temperature, humidity, concentration of S02, and adiabatic saturation temperature are summarized. PPSB and other techniques in semidry FGD are compared. It is concluded that PPSB technique in semi-dry FGD has its advantages and expansibilities. |
