摘　　要：本文从三基色测温原理出发,讨论了它在火焰温度场测量应用中受到的限制因素。通过对火焰模型和CCD光谱响应的简化,推导出了便于应用的测温公式。提出了通过系统标定和三种比色温度的相关性校正测量误差的方法。利用设计的一套测量系统,对某200 MW的锅炉的温度场分布进行了测量,并与双色温度计的测量数据进行了比较。结果表明,上述方法简单可靠、测量误差小于5％,可满足系统燃烧诊断和实时测控的目的,工程上有一定的应用前景。Starting from temperature-measuring principle of three primary-colors, certain factors in the application of measuring flame temperature field was discussed. A convenient temperature-measuring formula was deduced and method to rectify measuring errors by calibration of system and relationship of three colorimetric temperatures was put forward. Through a designed measuring system, it measured temperature field of 200 MW boiler, and compared it with the measured data of dual spectrum thermometer. Results showed that the way described above is simple, the error s is no more than five percent, and has high measuring accuracy to satisfy the purpose of systematic burning diagnosis and real-time measurement as well as control, resulting in certain applied prospects in engineering.
