The interferences from sampling flow,in situ temperature,and the back flushing of pretreatment device were discussed in monitoring the flue gas of high humidity and low sulfur dioxide using a portable non-dispersive infrared gas analyzer.Based on the laboratory and field tests,countermeasures were explored to eliminate these interferences,including controlling the sampling flow,ex-tending preheating of the equipment,and flushing the pretreatment device back,ensuring the stability and accuracy of the flue gas monitoring.
