| 摘 要： | 本文利用 8只火焰图像探测器和相应的计算机图像采集处理系统,在一台 200 MW 四角切圆燃煤锅炉上进行了炉膛三维温度场可视化实验研究。现场实验结果表明,炉膛上部温度分布较低,并且呈典型的单峰形状;燃烧器区域的温度分布较高,能够反应四角切圆燃烧特性。用水冷枪抽气热电偶对温度场可视化结果进行了检验,相对误差在5％之内。三维温度场可视化结果刷新一次的时间不超过5秒,满足在线监测的要求。

| Abstract: | This paper reported experimental visualization of three-dimensional temperature field inthe furnace of a 200MW coal fired boiler by 8 flame detectors and image processing hardware. Theresult indicated that the temperatures in the upper furnace were higher than those in the lower part,which presented a typical unimodal distribution, the temperatures around the combustor zone werehigh, showing the features of the flame. The visualization result could be updated once within 5seconds to meet the online monitoring requirement. The visualization results were compared with asuction thermocouple, and the relative errors were less than 5%. |
