The effectsof Ca/S molar ratio, approach to saturation of flue gas, SO_2 concentration and gas velocity onsulfur retention efficiency and calcium utilization rate are investigated. Desulphurizationcharacteristics of the two sorbents are compared. The mechanism of improving desulphurizationefficiency by water spraying is analyzed. The results show that the activities of two sorbents areimproved obviously by humidification with water spray and the caustic lime has better applicationprospect because of cheaper cost.展开更多
