基于Monte Carlo方法的锅炉烟尘烟气测量不确定度评定

Evaluation Uncertainties of Measurement of Smoke and Dust and gaseous pollutants emitted from Boilers Using Monte Carlo Method

采用蒙特卡罗方法模拟计算了锅炉燃烧排放的烟尘、烟气的折算排放浓度、排放速率的相对标准不确定,给出了各个输入量的相对标准不确定度分量。依据模拟计算结果对锅炉烟尘、烟气测量不确定度评定的数学模型进行了简化,探讨了采用灵敏度公式评定烟尘、烟气测量结果的合成不确定度中应当注意的问题,为锅炉燃烧排放的烟尘、烟气测量不确定的评定提供了依据。

On the basis of Monte Carlo method, we made research on evaluation uncertainties of measurement of smoke and dust and gaseous pollutants emitted from Boilers. The every related standard uncertainty component of measurement of smoke and dust and gaseous pollutants emitted from boilers were listed based on uncertainty of each input quantity, and related combined standard uncertainties of meas- urement of smoke and dust and gaseous pollutants emitted from boilers were also listed based on two ways： 1 ） the uncertainty of all input quantities were taken into account in the simulation ; 2 ） according to sensitivity coefficient and related standard uncertainty component of ev- ery input quantity. According to the results of simulation~ the mathematic model of evaluation uncertainty of measurement of smoke and dust and gaseous pollutants emitted from boilers was simplify to make it easy to understand and calculation.
