Effects of anthracite replacing coke breeze on iron oresintering
Published online by Cambridge University Press: 05 June 2008
Abstract
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 anthracite is ascribed to the lower density of heat source particles and to the lower heat value and more volatile matters of anthracite. A smaller particle size for anthracite is recommended. Some subsidiary heat sources such as magnetite ore and mill scale could be helpful for more uniform sintering.
