摘要/Abstract

摘要： 消除湿烟羽已成为当前重大环保需求。对消除湿烟羽技术中的关键参数，如烟气加热温度（过热度）与环境温度、环境相对湿度、气压以及烟气温度之间的耦合关系，进行定量、全面分析。研究结果表明：过热度随环境温度升高、气压降低呈指数降低，而随环境相对湿度升高、烟气温度升高呈指数增加；环境温度10 ℃以上时，过热度受环境相对湿度影响的敏感性略强于受环境温度影响的敏感性；气压变化可引起过热度的显著波动，因此对于不同项目，设计时应充分考虑地域性的气压差异；烟气温度变化同样可导致过热度的显著波动，证明消除湿烟羽时应严格控制烟气温度，以便充分利用冷凝再热法的技术优势。

Abstract: The demand for industrial wet plume elimination has been rising sharply in the current environmental protection strategy. In this paper the influence of environmental conditions are analyzed quantitatively and comprehensively, such as ambient temperature, ambient relative humidity and air pressure, as well as the flue gas temperature on the degree of superheat, which is the key parameter in wet plume elimination technology. The results show that the degree of superheat decreases exponentially with the increase of ambient temperature or the decrease of air pressure, and increases exponentially with the increase of ambient relative humidity or flue gas temperature. When ambient temperature is above 10 ℃, the sensitivity of ambient relative humidity to the degree of superheat is slightly higher than that of ambient temperature. As the fluctuations of air pressure may cause drastic changes of the degree of superheat, the variations of regional air pressure should be taken into fully consideration in the design for different projects. Since the degree of superheat also varies significantly with flue gas temperature, the flue gas temperature should be monitored under strict control in wet plume elimination such that the technical advantages of Cooling &Reheating method could be fully utilized.

Key words: wet plume elimination, degree of superheat, environmental conditions, flue gas temperature, sensitivity coefficient
