Abstract
Permeability experiments have been performed for each characteristic zones (moisture condensation, drying, reaction, melting and cake zone).
The analysis of reaction zone is satisfactorily made by combination of static experimental test and mathematical dynamic model in sintering process.
By this model including pressure drop equation of each zones, calculations are made simultaneously for the variation of heat transfer, moisture transfer, reactions of coke and limestone, melt of solid and suction gas volume rate.
It is concluded that the total gas volume is determined by the ratio of the specific heat of material to that of suction gas, independing on suction pressure or bed height.
