| 摘 要： | 通过对电站锅炉煤燃烧过程中氮氧化物生成模型的分析，确定了与氮氧化物生成量密切相关的锅炉运行参数。使用燃烧火焰图像处理技术和辐射传递方程反演测量，得到炉膛温度场变量。将锅炉运行参数和温度场变量联合构建一个输入数据矩阵，利用偏最小二乘法对锅炉运行过程中的氮氧化物排放值进行估计。并同实测值进行对比。分析结果表明：该种方法可以用于在线实时预测污染物的排放量。图1表3参9

| Abstract: | By the analysis of the generation NO_x model during coal combustion in utility in utility boilers in this paper, the boilers function parameters related with generation NO_x quantity are determinated. The temperature distribution variable is gained by using combustion flame image processing technique and radiation transfer equation inversion measurement. The boilers function parameters and the temperature distribution variable are combined to construct a input-data matrix, using least square method to estimate the output NO_x quantity during boilers running, and compare it to practical value. The analysis result showes, the method can be used to predict the output pollutant real-time. Fig 1,tables 3 and refs 9. |
