摘要
燃煤电厂烟气脱硫大多采用湿法脱硫原理,导致脱硫尾部烟气排放温度低、湿度高、二氧化硫浓度低,现有的二氧化硫监测采样系统和仪器无法准确测定其排放浓度。通过对不同方法和仪器的对比实验,确定了适合在低温、高湿、低二氧化硫排气情况下的采样分析方法。
The wet desulfurization method has been normally used in coal-fired power plants,which causes low temperature, high moisture and low concentration of SO2 in emission gas. Thus, the existing sampling systems and instruments cannot measure the SOo emission concentratiort exactly. The best sampling and analyzing methods through different experiments were confirmed.
