Correlativity between Pulverized Coal Combustion in BF Raceway and Radiant Image

WEN Liangying, BAI Chenguang, CHEN Dengfu, DONG Lingyan, QIU Guibao,OUYANG Qi (College of Materials Science and Engineering, Chongqing University, Chongqing 400044,China)  
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.
