摘　　要：根据《测量不确定度评定与表示》(JJF1059-1999)、《工业锅炉能效测试与评价规则》(TSG G0003-2010)和《工业锅炉热工性能试验规程》(GB/T 10180-2003)建立了工业锅炉热效率不确定度数学公式,并对一台燃油锅炉热工测试进行不确定度计算分析。排烟处CO含量、排烟温度和收到基氢的不确定度分量对反平衡热效率的不确定度影响较大。降低这些相关测量仪器的不确定度可以提高锅炉热效率测试的可靠性。The uncertainty mathematical model of the thermal efficiency of industrial boilers was established base on Evaluation and Expression of Uncertainty in Measurement （JJF1059.7-20TX）, Energy Efficiency Test and Evauation Pegulation for Industrial Boiler （TSG G0003-2010）, Thermal performance test code for industrial boilers（G]3/ T 10180--2003）. Then an oil--fired industrial thermal test was employed s an example to illustrate the proposed method and the uncertainty of anti-balance thermal efficiency was calculated. The result and analysis indicated that the uncertainty was most affected by the test of CO＇, tpy, Hat. The reduce of the uncertainty of the related measuring instrument can improve the reliability of the anti-balance thermal efficiency test of the boiler.
