烟道气二氧化硫测定方法的选优

Optimal Method for Monitoring SO_2 in Fluegas

本文从烟道气ＳＯ２ 监测的实际出发，较全面分析了现行测定方法综合指标的优缺点。并通过经济、技术和国情等多种因素对比考证，优选出了较为适宜的电导法。同时还论述了对传统电导法的改革创新。使之不仅在选择性、灵敏度、抗干扰能力等都有较大的提高，而且与同类进口仪器的对比实测中也显示出优良性能。从而得论：创新电导法是烟道气ＳＯ２ 监测的较为理想的优选方法。

This paper,based on monitoring data of SO2 in fluegas,provided a systematic analysis on merits and demerits of testing methods being adopted now.Meanwhile,by comparing and researching various factors of economy,technology and national conditions,it selected a more suitable method,i.e. conductance.Besides,it also discussed renovation of the conductance method with respect to its selectivity,stability,sensitivity and antijamming.Moreover,compared with those imported devices of the same kind,it is found that the medified device showed its fine quality over others.
