摘　　要：我国多数燃煤电厂湿法烟气脱硫工艺饱和湿烟气直接排放,形成可视湿烟羽。当下已有许多环保节能技术对湿烟羽治理有明显效果,但技术指标尚未结合湿烟羽治理来制订。湿烟羽治理技术可归纳为三大类:加热类、冷凝类、冷凝再热类。对各类技术的特点及其在湿烟羽治理中的适应性进行了研究,并结合湿烟羽形成和消散机理探索了三类技术在不同环境温度、环境湿度条件下的适用范围。The wet flue gas after desulfurization process of most coal - fired power plants in China is saturated and directly discharged to form visible wet plume. At present, there are many environmental protection and energy saving technology that have a significant effect to the wet plume control, but the technical indicators have not yet develop combined wet plume control. Wet plume control technology can be summarized into three categories： reheating, condensation, condensation and reheating. The characteristics and adaptability of various technologies applied to wet plume control are studied. Combining the formation and dissipation mechanism of wet plume ,the application of the three types of technologies under different ambient temperature and environmental humidity conditions is explored.
