Parametric Studies

A three-dimensional multiphase CFD model using an Eulerian approach is developed to simulate the process of pulverized coal injection into a blast furnace. The model provides the detailed fields of fluid flow velocity, temperatures, and compositions, as well as coal mass distributions during the devolatilization and combustion of the coal. This paper focuses on coal devolatilization and combustion in the space before entering the raceway of the blast furnace. Parametric studies have been conducted to investigate the effect of coal properties and injection operations.

Hcl Gas

In the combustion process of pulverized coal injection into blast furnace, the chlorine goes into the unburned pulverized coal is about 17%, the chlorine in the unburned coal keeps original state; The chlorine goes into the blast furnace gas is about 83%, and these chlorine stay as Hcl gas. Changes in air temperature and oxygen rate had no significant effect on the decomposition of chlorine in coal, resulting the rate of Cl into the blast furnace gas is difficult to increase significantly.
