Theoretical Analysis of Gas Flow in Shaft with Layered Burdens

Abstract

To clarify the characteristics of gas flow in the blast furnace shaft with layered ore and coke burdens, the flow equations of continuity and motion were numerically solved for the isothermal flow in two-dimensional bed.
The effects of mass flow rate of gas, compressibility of fluid, shape of bed and non-uniform distribution of permeability on the flow field such as patterns of streamline, mass velocity and isobar in the bed are discussed on the basis of the results calculated for gas fed into the bed at isobaric condition.
