摘要
我国湿法烟气脱硫系统在引进之初均采用再热系统，但在实际运行中，再热系统的日常维护和运行问题较多，运行成本高。因此烟气脱硫后的净烟气排放是否进行再热处理一直困绕着产业界。介绍了湿法烟气脱硫烟气排放的各种方式，并对它们的特点进行了比较。
China＇s introduction in the early days of using reheat system in wet desuifurization. Considering the role of reheat system and problems which were brought about in the actual operation, Whether or not the flue gas needs to be reheated after desuifurization , the FGD industrial people are confused all along. Several reheating methods for FGD are described with their technical features analyzed.
