摘要

In order to improve the coke combustion efficiency during iron ore sintering, the effect of coke granule structure was investigated with a TG-DTA and a new combination heating equipment capable of establishing similar heating pattern to the actual sintering bed. The results were analyzed as a function of granule type and neighboring specie as follows: The granule type was crucial to the combustion behavior of granules. On the other hand, the effect of neighbors was distinct over core coke particles; meanwhile, the effect remained uncertain in pellet type granules. The authors recommend composite type granules (fine coke particles adhering on a core particle) for the best choice. The type should bring 1.2% save of coke consumption and 2.3% increase in the heat front speed in comparison to coke particles of single type.
