利用光闪烁现象进行粉尘排放的监测

粉尘排放监测系统正在各国推广应用，新的方法也不断出现．本文提出一种基于光闪烁现象的粉尘排放监测方法．同光透射法相比，这种新方法具有测量精度高、不怕污染、成本低的特点．实验结果表明，测量系统的输出与粉尘排放的浓度呈线性关系．

PARTICULATE EMISSION MONITORING BY USE OF SCINTILLATION EFFCT

Continuous emission monitoring systems are becoming increasingly prevalent in industrial plants worldwide. Many new approaches have constantly emerged. The paper presents a new method of particulate emission monitoring based on scintillation. Compared with opacity systems, the new method has many advantages such as higher precision, higher tolerance of instrument contamination and lower cost. Experiment results show a linear response to particulate concentrations.
