摘要:
使用干湿球法、重量法和阻容法3种常用的烟气含湿量测量方法,对5种固定污染源工况条件下的烟气含湿量进行测定,分析每种方法的适用范围和准确度。结果表明,重量法和阻容法测量结果的精密度、相关性、准确度较好;干湿球法对于温度超过100 ℃的烟气,其测量结果准确度较低,且受到烟气正压影响比较大。

Abstract:
Wet and dry bulb thermometer measurement, gravimetric method and resistive and capacitive moisture measurement were used to measure the moisture content of flue gas under the working conditions of 5 stationary sources. The applicable range of each method was analyzed, as well as the method accuracy. The results show that the precision, correlation and accuracy of the gravimetric method and resistive and capacitive moisture measurement are good. For the flue gas with temperature over 100 °C, the wet and dry bulb thermometer measurement has low accuracy and is positively affected by flue gas pressure.
