摘要:
对2种便携式烟气预处理器在比对监测中的实际应用进行探讨,通过对2种烟气预处理器工作原理及在实际应用中的监测数据进行分析比较,显示在“高湿低硫”条件下,电子冷凝预处理器析出的冷凝液会造成二氧化硫的损失,在应用中应加快除水,减少烟气与冷凝水接触的时间,并防止冷凝液出现在伴热管线与预处理器烟气入口之间。而便携式Nafion预处理器由于具有独特的干燥性能,抗干扰能力,在“高湿低硫”的比对监测中具有较好的可比性和适用性。

Abstract:
Practical applications of two portable flue gas pre conditioning instruments in comparison monitoring were discussed. By comparing the principles of the two instruments and data obtained from practical applications, it was found that under the condition of high humidity and ultra low emission,SO2 loss would occur as a result of condensation fluid from electronic cooler. It was suggested that water should be removed more quickly during application, and reduce the contact time period between the gas and the condensation fluid. In addition, the condensation fluid should be prevented from present in between the thermos tube and the inlet of the pre conditioning instrument. Portable Nafion pre conditioning instrument has unique drying performance and capability of resisting interference, and it provides good compatibility and applicability in comparison monitoring test in high humidity and ultra low emission.
