摘要
烟道气中的二氧化硫干扰因素多,不容易测准.本文通过对比实验认为.影响采样精度和分析准确度的干扰因素有:(1)转子流量计的影响;(2)冷凝水对二氧化硫的吸附;(3)氮氧化物对测定的干扰。严格控制上述实验条件,即可得到准确的二氧化硫浓度值。
The interference factors on determination or SO2 in fluepo is complex,and no easy to determine exactly. In this Paper. by theCorrelation experiments, we think the interference factors of determination are: (1 )the correction of rotameter now meter ; (2 )the absorption of SO2 by condensing water ; (3)the interference of NOx. If controlled strictly such experimental condiations, the exact concentrationvalue will be obtained.
