摘　　要：发电厂锅炉燃烧状况不仅直接影响发电效率,还会影响污染物排放和能量消耗。本文从燃烧火焰图像、炉膛温度分布与锅炉烟气成分3个技术路径来综述锅炉燃烧监测方法。详细探讨了火焰燃烧图像的采集与特征提取,简述了炉膛温度测量主流方法的基本原理,还对各烟气监测方法的优劣进行比较分析,为研究人员开展相关工作提供了技术参考。The combustion conditions of boilers in power plants not only directly affect power generation efficiency,but also influence pollutant emissions and energy consumption.This paper provides an overview of boiler combustion monitoring methods in three technical paths:combustion flame image,furnace chamber temperature distribution and boiler flue gas composition.The acquisition and feature extraction of flame combustion images are discussed in detail,the basic principles of the mainstream methods of furnace chamber temperature measurement are briefly described,and the advantages and disadvantages of each flue gas monitoring method are compared and analyzed,providing a technical reference for researchers to carry out related work.

关 键 词：燃烧监测 火焰图像 温度分布 烟气含氧量 飞灰含碳量
