Description
Short description:
Covers the full blast furnace process, including zones, gas-solid reactions, combustion, and iron reduction to molten form.
Long description:
This module explores the entire process flow within a blast furnace, focusing on the sequential physical and chemical transformations of iron-bearing materials. Learners examine each furnace zone from throat to hearth, interpreting schematic views and reaction mechanisms. The training includes in-depth coverage of combustion at the tuyères, gas-solid interactions, and the reduction pathway from hematite to metallic iron. It explains the role of pulverised coal injection and hot blast preheating. By tracing gas flow and burden descent, the module provides a complete understanding of the interdependent reactions that convert raw materials into molten iron and slag.
What you will learn
- Identify each zone within a blast furnace and explain its physical and chemical characteristics.
- Describe the reaction sequence from hematite to metallic iron, detailing gas and direct reduction.
- Explain the function and thermal importance of the tuyère and raceway zones in coke combustion.
- Outline the burden charging process and the effect of radial distribution on reduction efficiency.
- Summarize key chemical reactions in each thermal zone, including the Boudouard and solution loss reactions.
