- Abstract:
- The experimental results of flue gas desulphurization with caustic lime and hydrated lime activated by water spraying in a desulphurization reactor are presented. The effects of Ca/S molar ratio, approach to saturation of flue gas, SO2 concentration and gas velocity on sulfur retention efficiency and calcium utilization rate are investigated. Desulphurization characteristics of the two sorbents are compared. The mechanism of improving desulphurization efficiency by water spraying is analyzed. The results show that the activities of two sorbents are improved obviously by humidification with water spray and the caustic lime has better application prospect because of cheaper cost.
