摘要
利用辐射图像处理方法对一台单火嘴卧式试验炉开展了三维温度场测量的实验研究,并结合温度分布分析了燃烧器火焰长度、火焰直径等特征参数,与图像边缘提取算法得到的火焰外形参数一致.通过多支热电偶对温度场监测精度进行了验证,测量误差小于6%.将三维温度场测量技术应用于单燃烧器火焰监视,有助于全面了解火焰燃烧状态,指导燃烧器优化设计.
Three-dimensional temperature distribution measurement experiment was carried out on a single nozzle horizontal furnace by radiation image processing technology, and the nozzle characteristic parameters such as flame length and flame diameter were analyzed according to temperature distribution, which were consistent with the resuits from image edge extraction algorithm. The temperature monitoring accuracy was verified througth several thermocouples, and the measurement error was less than 6%. The application of three-dimensional temperature distribution measurement technique to single nozzle combustion monitoring would help the comprehensive analysis of flame state and guide the optimization design of nozzle.
