Abstract

In order to clear the effect of coke quality on coke degradation in a blast furnace raceway at high rate of pulverized coal injection, experiments by a hot model simulating the raceway were carried out. The results were as follows.<BR>(1) Reactivity and strength of coke effect on combustion behavior of pulverized coal and coke in the raceway, coke degradation in the raceway and the raceway structure.<BR>(2) Using high reactivity coke, thickness of reacted layer near the lump coke surface is thin.<BR>(3) Using high reactivity and high strength coke, coke degradation in the raceway is suppressed.
