电厂锅炉火焰的温度场分布对于电厂的安全运行和燃烧诊断都具有极其重要的现实意义。运用计算机图像处理技术测量燃烧火焰的温度场分布是近年来国内外得到较多研究的一项技术。文中采用彩色ＣＣＤ摄像机对炉膛火焰进行温度场计算，并对计算方法的误差进行了详尽的分析。试验结果表明，此方法简便可行，具有投入工业现场应用的前景。 The distribution of temperature field of boiler flame in power plant is of extremely important practical significance for the safe operation and combustion diagnosis of power plant. The use of computer image processing technology to measure the distribution of the temperature field of the combustion flame is a technique that has been studied more and more at home and abroad in recent years. In this paper, a color CCD camera is used to calculate the temperature field of the furnace flame, and the error of the calculation method is analyzed in detail. The test results show that this method is simple and feasible and has the prospect of application in industrial field.
