Abstract
The effective drainage of liquids from the hearth is a major problem in the operation of large commercial blast furnaces. Because of the nature and complexity of the blast furnace process, mathematical modelling provides a powerful means of obtaining the insight into the drainage process which is necessary for this problem to be overcome.
A mathematical model which allows a prediction of the position of the gas-liquid interface during the drainage of a two-dimensional packed bed is described. The calculations are compared with drainage experiments conducted on a laboratory scale packed bed and the agreement between the two results is shown to be excellent. On the basis of the computations carried out it is concluded that hearth drainage is improved by the adoption of a continuous tapping procedure, an improvement in coke quality and a reduction in slag viscosity.
