①干湿球法：烟气温度越高饱和水蒸汽压和烟气含湿量越大。当干球温度小于３８℃时要对取样管加热保温，以免烟气到达露点，水汽冷凝而产生误差；待干、湿球温度相对稳定时迅速读数以免湿球蒸干；测定三次取其算术平均值。②冷凝法：抽气流量大于２０Ｌ／ｍｉｎ冷凝效果不... ① wet and dry bulb method: the higher the flue gas temperature saturated vapor pressure and flue gas moisture content. When the dry-bulb temperature is less than 38 ℃, the sample tube must be heated and insulated to prevent the flue gas from reaching the dew point and condensing with water vapor to produce error. When the dry-bulb temperature is relatively stable, the wet bulb should be quickly read to avoid wet bulb drying. value. ② condensation method: pumping air flow rate greater than 20L / min condensing effect is not ...
