摘要 火焰温度是表征垃圾焚烧炉炉膛内燃烧状态的最重要参数之一,测量火焰温度已成为燃烧诊断的主要方式。本文基于城镇生活垃圾火焰特性和CCD图像技术,将图像处理技术、图像标定以及辐射测温原理有机结合,提出一种基于可见光辐射特性的垃圾焚烧炉膛火焰温度测量方法与装备,并将该方法应用于生物质火焰实验以检测其测温精度。结果表明,该图像测温法的测量结果准确性较高,与热电偶测量值的误差小于5%。该方法可以得到焚烧炉火焰的二维温度场分布,具有快速响应、适应能力强、应用范围广等优点。 Flame temperature,as one of the most important parameters characterizing the combustion state in the furnace of a garbage incinerator,has become the main method of combustion diagnosis by measuring flame temperature.Based on the flame characteristics of urban household waste and CCD image technology,combining image processing technology,image calibration,and radiation temperature measurement principles,a method and equipment for measuring the temperature of waste incineration furnace flames based on visible light radiation characteristics was proposed,and was applied to biomass flame experiments to detect its temperature measurement accuracy.The results show that the measurement accuracy of the image temperature measurement method is high,and the error with the thermocouple measurement value is less than 5%.This method can obtain the two-dimensional temperature distribution of the incinerator flame,which has the advantages of fast response,strong adaptability,and wide application range.
