Abstract

In order to increase the combustion efficiency of coke breeze in sintering process, thermogravimetry-differential scanning calorimetry tests of coke breeze and sintering pot tests were carried out. The effects of particle size of coke on combustion and sintering process were examined. The surface air velocity and the exhaust gas composition of a sintering machine were also tested in a sintering strand. The results showed that the fine coke breeze burned quickly, but high ratio of fine particle in coke breeze was not beneficial for the improvement of the sinter quality. The low permeability of the front section of the sintering machine caused the low combustion efficiency of coke breeze which could be improved by increasing the coarse powder ratio of coke breeze .
