固定源废气监测仪器使用中常见问题及排除

摘要

针对固定源废气监测过程中出现的关于监测仪器使用方面（包括传感器、内置泵及日常的校准），监测参数（包括动压、过量空气系数），采样位置不符合要求、烟道面积过大，运行负荷如何确定等常见问题进行了分析、探讨与总结，并提出了相应的改进方法和建议。%This paper aimed at analyzing,discussing,and summarizing the problems during the operation of emission monitoring e-quipment of stationary sources,as well as proposing improved methods and suggestions to solve these problems.Specifically,these problems included failure of the monitoring equipment due to the transducer,the built -in pump,and daily calibration,determination of monitoring parameters containing dynamic pressure and excess air ratio,nonstandard sampling locations,excess large flue area and the uncertain operating load.
