数字图像炉膛火焰检测试验及污染物排放灰色关联研究

Study on Digital Imaging Combustion Monitoring Test and Pollutant Emissions Based on Gray Relational Analysis

基于数字图像火焰检测是近代的一种新型可视化燃烧诊断方法。利用该系统对炉膛温度场进行了测量。在各种不同工况下,对锅炉负荷、煤种、过量空气系数、炉膛温度等因素同锅炉污染物排放特性之间的关系进行了实验研究。利用灰色理论对实验结果进行了分析,从而对降低污染物排放提供参考。

Users of imaging digital technology for combustion monitoring and diagnosis are new method. In this paper , the relationships between the NOx emission and boiler load, excessive air, hot air temperature, terminal air and coal quality and so on is studied in the test. Application of gray correlation analysis for the result of test showed that the method is effective to reduce pollutant emissions.
