定电位电解法测定发电锅炉废气中二氧化硫折算浓度的不确定度

Uncertainty in Determination of Converted Concentration of Sulfur Dioxide from Power Plant Boiler Emission by Fixed Potential Electrolysis Method

根据《测量不确定度评定与表示》(JJF1059.1-2012)、《测量不确定度评定和表示》(GB/T27418-2017),提出适用于依据《固定污染源废气二氧化硫的测定定电位电解法》(HJ 57-2017),并考虑含氧量因素,进行燃煤发电锅炉、生活垃圾焚烧锅炉烟气中二氧化硫折算浓度测定不确定度评定方法的研究。

According to the"Evaluation and Expression of Uncertainty in Measurement"(JJF 1059.1-2012)and"Guide to the evaluation and expression of uncertainty in measurement"(GB/T 27418-2017),a method of evaluation of uncertainty in determination of converted concentration of SO2(based on the"Stationary source emission—Determination of sulfur dioxide—Fixed potential by electrolysis method"(HJ 57-2017))from power plant boiler,including coal-fired boiler and municipal solid waste incineration boiler emission was proposed.
