Abstract
Blast furnace is a principal metallurgical reactor in ironmaking process, and
usually treated as a counter current moving bed reactor. In the lower part of
this reactor, flows of gas, solid, liquid and powder exist at the same time.
With recent increase in pulverized coal injection, operation problems due to
deposition of fine particles in this zone have been arising. The authors
developed a process simulator of blast furnace treating more than four different
phases that had individual flow mechanisms. In this study, mathematical
formulations describing powder deposition rate by difference between adhering
and departing rates has been introduced, and the simulator is able to handle
flowing and deposited powders separately. It is assumed that the deposited
powder ph
