Design of the sample pretreatment system for flue gas on-line analysis

Nowadays, the technology of flue gas on-line analysis in different circumstances need to use different pretreatment system, which is not conducive to the promotion of on-line analysis techniques. According to the principle of “ cold dry process” to design an online analysis of flue gas sample pretreatment system, which can be achieved sampling and sample pretreatment in the slight positive pressure or negative pressure environment, ultimately meet the requirements of most of online infrared analyzer.
