Abstract

Accretion on the lining of the blast furnace results in a harmful effect on burden descent, which also has a negative effect on energy balance. This eventually leads to increased CO2 emission. We examined which blast furnace zones were significantly affected by the thickness of the accretion layer and how this affects the blast furnace gas stream relations. Using a heat transfer model, the samples taken from the accretion and statistical analysis of the typical operating parameters of the blast furnace, a mathematical model was created in order to determine the thickness of blast furnace shaft accretion and its effect on gas utilization.
