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.
