摘要

摘要: 针对空气的气压、温度、相对湿度对烟气热力状态、湿烟羽的形成和湿烟羽治理技术的影响进行研究。结果表明:空气特性会影响饱和湿烟气温湿度的选定;空气温度对湿烟羽的影响程度大于相对湿度;气压对排烟温度的影响随饱和湿烟气温度的降低而增大;空气温度降低,排烟温度的基准变化率减小。空气温度和相对湿度会影响湿烟羽消白效果,由所需消白效果决定烟气的冷凝及再热温度。

Abstract: The influences of air characteristics such as pressure, temperature and relative humidity on the thermal state of flue gas, the formation of wet plume, and on the effectiveness of wet plume control technologies were analyzed. Results showed that air characteristics would affect the selection of temperature and humidity of the saturated flue gas. The temperature of air had a greater effect on wet plume than its relative humidity. In addition, the influence of air pressure on gas emission temperature increased with the decrease of the temperature of the saturated wet flue gas. The lower the temperature of the air was, the smaller the reference change rate of gas emission temperature would be. Air temperature and relative humidity would affect white smoke elimination effect and the desired effect would then determine the condensation and reheating temperature of flue gas.
