The space from the outlet of coal injected gun to the center of raceway in the blast furnace is the key district for pulverized
coal burning.In order to establish the correlativity between the
pulverized coal combustion in blast furnace raceway and the radiant image, the relationships between two dimensional radiant images and three dimensional rediant energy in blast furnace raceway are discussed on the base of the correlativity of the numerical simulation of combustion processes with the connection that radiant images information and space
temperature distribution. Taking the radiant images as a kind of radiative boundary for numerical simulation of combustion processes, the uneven radiate characteristic parameter can be calculated. The integrating method between the numerical simulation of combustion processes and the radiant images processing are obtained. The method to examine three-dimensional temperatures distribution in blast furnace raceway is put forward by two dimensional imaging technique.
