摘　　要：火力发电厂烟气脱硫(FGD)的方法很多,其中石灰石湿法烟气脱硫技术因其成熟、可靠、脱硫率高,在烟气脱硫中占有主导地位。但在石灰石湿法烟气脱硫中,石灰石在水中的溶解度很低,其溶解过程成为控制步骤之一。使用添加剂提高脱硫效率具有用量少、成本低、不需附加装置、操作简单、使用方便、对FGD装置操作影响小等优点,是提高FGD装置脱硫效率简单、有效的方法,已成为FGD应用研究的热点。Flue gas desulfurization in thermal power plant (FGD) in many ways, including limestone wet flue gas desulfurization technology because of its mature, reliable, high desulfurization efficiency, occupy the dominant position in flue gas desulfurization. But in the wet flue gas desulfurization with limestone, limestone solubility in water is very low, the dissolution process was the control step of. The use of additives to improve the desulfurization efficiency with less dosage, low cost, no need of additional devices, simple operation, convenient operation, little influence on FGD device use, is a method to improve FGD efficiency of desulfurization is simple, effective, has become a hotspot of FGD application research.
