Influence of Slow Descent of Solid upon the Fluids Flow Behavior in Packed Beds Irrigated by a Liquid Counter-current to an Uprising Gas Stream.

Abstract

In the uppe~p art of the dropping zone in a blast furnace, gas and liquid flow upwardsand downwards and the flow behavior has been investigated by using fixed beds. However, burden continually descends there. In the present work, Iiquid hold-up and gas pressure loss in fixed and moving beds were measured to examine the effect of solid movement.
