摘要
采用HJ/T57-2000定电位电解法对锅炉烟气中SO2进行监督性监测。监测结果按《测量不确定度评定和表示方法》(JJF1059.1-2011)的要求,对SO2的测量结果进行不确定度评定。通过对结果有影响的各不确定分量的分析与量化评估,计算得到相对扩展不确定度U95=6.67%,有效自由度Veff=13。
The supervisory monitoring and measurement on sulfur dioxide from boilers is based on the HJ/ T57-2000 constant potential electrolysis method.The measurement uncertainty of sulfur dioxide measurement re sults is assessed according t＂o Assessment and representation of measurement uncertainty＂.By analysing and quantifying the different uncertainty component that affects the result.Therefore,the calculated result is that U95=6.67% and Veff=13.
