Abstract

According to the principle of spectral radiation, a color Charge-coupled-Device (CCD)–based sensor pyrometer system has been established for the detection of combustion in the blast furnace tuyere raceway. The two-color method is applied to calculate the two-dimensional projection temperature distribution, as it has great advantages in the harsh measurement environment. In this paper, the radiation images of the flame in the raceway are photographed using a color CCD camera and its two-dimensional projection temperature distribution is obtained by the two-color method with image processing technology. The results show that the average projection temperature of 320 and 5500 m3 blast furnace are about 2260.5K and 2266.8K, respectively. The measured results are basically agreed with the theoretical combustion temperature. It is indicated that the temperature measurement system developed in this paper can accurately valuate the combustion situation in the raceway and it contributes to the stable operation of the blast furnace.
