摘要

阐释了火焰特征量定义及火焰识别原理,并利用辐射图像处理系统对一台马蹄焰玻璃窑炉的火焰特征进行了监测研究和分析。结果表明:火焰二值化识别结果与火焰图像一致,证明了火焰识别原理的可靠性,因而基于火焰识别原理提取的火焰特征量亦是准确的。这三种火焰特征量能较好的对火焰进行量化描述,分别反映火焰覆盖熔池的面积、火焰与炉墙的安全距离及火焰的热辐射水平。这三项指标与窑炉燃烧优劣及安全生产直接相关,可用于监测指导运行。监测的火焰特征量与现场DCS燃气量数据变化趋势保持一致,说明火焰特征量能够较好的反映炉内燃料量的调节过程,为后期基于火焰特征量进行优化燃烧调整打下基础。
        The definition of the flame characteristics and the principle of flame identification are explained in detail, and are analyzed the flame characteristics of a horseshoe flame glass furnace. The results show that the flame binarization recognition result is consistent with the flame image, which proves the reliability of the flame recognition principle. Therefore, the flame characteristics extracted based on the flame recognition principle is also accurate. The three flame characteristics can quantify the flame, reflect the area of the flame-covered molten pool, the safety distance between the flame and the furnace wall, and the heat radiation level of the flame. The three indicators are directly related to the quality of combustion and safe production, and can be used for monitoring and guiding operation. The flame characteristics are consistent with the change trend of the on-site DCS gas data. It is indicated that the flame characteristics can be better reflect the adjustment process of the fuel in the furnace, which lays the foundation for the optimization of combustion adjustments based on the flame characteristics at a later stage.
