A Mathematical Model for Blast Furnace Operation with Inclined Layers of Burdens

Abstract

A mathematical model of the blast furnace with the layered coke and are burdens in which the thickness of each layer varies in the radial direction has been developed over the region from the toplevel to the melting zone of the furnace.
On the basis of this model, the longitudinal and radial distributions of the process variables, such as temperature, gas composition, gas velocity, and fractional reduction of ironre, in an existing blast furnace in Japan, B. F.(D II), have been analized with the aid of a digital compute.
It is found from the calculated results that the radial distributions of the process variables mentioned above and the melting level are remarkably uneven in B. F.(D II), and are similar to the results observed by the other investigators.
