Quantitative Estimation of Gas Permeability of Softening Sinter Layer with Liquid Phase

抄録

Quantifying gas permeability of softening sinter layer was studied with the aim of increasing the precision of gas permeability in cohesive zone.
In this study, the effect of liquid in packed bed on gas permeability was evaluated by a cold model experiment, which simulated sinter melting behavior by using sponge ball absorbed glycerin solution. As a result, gas permeability of packed bed with liquid was expressed by formula (a), based on Sugiyama’s formula.

Formula (a) was adapted to actual softening sinter experiment result, and was confirmed to be good agreement.
