2016-9-9  Abstract— The coke breeze is the common solid fuel for iron sintering plants. The high consumption of coke breeze leads to its depletion as the most of the fossil fuels. Several researches, nowadays, focus on finding different alternatives that can replace the coke breeze either partially or completely. In this study, the charcoal was used as a supplementary fuel in the iron ore sintering process. Coke breeze was partially replaced by charcoal in sinter charge. The results of this work shows that the replacement of coke breeze

Effects of anthracite replacing coke breeze on iron ore

2008-6-5  Anthracite coal as fuel for iron ore sintering is compared with coke breeze. Anthracite is lower in porosity, higher in density, and slower in combustion rate. With higher proportion of anthracite in fuel, permeability of sinter bed tends to decrease resulting in lower sinter productivity. Higher fuel rate with more replacement of coke breeze by
