摘要
参照美国EPA 30B方法,基于吸附原理,研制了用于燃煤燃烧源排放烟气中总气态汞的双路独立采样系统,结合热解析分析技术,现场测试结果符合30B方法的质控指标要求。建议加大国产吸附管的研制力度,开发适用于中国工况的汞采样器。
U.S. EPA Method 30B is a procedure for measuring total vapor phase mercury(Hg0 and Hg2 +) emissions from coal-fired combustion sources using sorbent trap sampling and an extractive or thermal analytical technique.This paper describes a design of highly integrated,small size,light weight portable mercury sampling device,referring to method 30B.Field test results combined with thermal analytical technique are in line with the quality control specifications of EPA method 30B.
