(PDF) Optimization of Sinter Plant Operating Conditions
Use of pellet gives rise to uniform bed permeability in comparison with iron ore or sinter This leads to better gas–solid contact resulting in higher productivity at reduced coke and fuel rate In general, a higher porosity raw material leads to a better reduction behavior for iron ores, pellets, and sinter The reason is better permeability, which allows the reducing gas to reach the reaction interface Pore diffusion of the reducing gas through the particles is very important and can be a ratelimiting step during the reductionReduction of Iron Oxides with Hydrogen—A Review The shape of pellets is near spherical and hence built permeability of the burden is much better than that of sinter [1] Use of pellet burden reduces hanging, which is often observed if a high proportion of sinter is used; the used of pellets saves coke by 25kg/t and the productivity by 15% [1]AUCTORES 675
