摘　　要：质量平衡率一般用来判断测试样品的准确性与可靠性。为了确定安大略法、EPA-30B法的准确性及可靠性,利用电除尘烟气中总汞监测结果等数据进行电厂汞平衡分析。汞在烟气及煤中的含量较低,汞的质量平衡率在70%~130%范围内可接受。本实验锅炉+除尘器安大略法、EPA-30B法总汞平衡率为72.62%~99.58%,均在参考范围之内,说明本次测试燃煤烟气中的汞取样操作可靠、测试数据准确、可信度较好。Mass balance rate is generally used to judge the accuracy and reliability of the test samples.The mercury balance of power plant was analyzed by monitoring results of total mercury in ESP-flue gas.In order to determine the accuracy and operation reliability of the Ontario method and the EPA-30 B method.The content of mercury in flue gas and coal is low,the mass balance rate of mercury is acceptable in the range of 70%~130%.In this work,the boiler dust remover ＋ Ontario method and the EPA-30 B method of total mercury balance at a rate of 72.62% to 99.58%,were in the range of literature.The results show clearly that the test sample of mercury in coal-fired flue gas is reliable to operate.Accurate test data and high reliability can be obtained.
