Introduction to Coal’s Role

Coal is a multifaceted resource essential for energy production and various industrial processes. Its abundance and calorific value make it a preferred choice historically; however, the environmental implications drive the global conversation today.

Electricity Generation

A significant portion of coal is used for electricity generation. In coal-fired power plants, coal combustion generates steam, which drives turbines to produce electricity. Despite coal’s waning footprint in some regions, it still accounts for a large percentage of global electricity consumption.

• Key Processes: Coal combustion, steam generation, turbine movement.
• Technologies: Integrated Gasification Combined Cycle (IGCC), Supercritical and Ultra-supercritical steam cycle.

Industrial Uses of Coal

Beyond electricity, coal is indispensable for several industrial functions.

• Steel Production: Coal, particularly coking coal, is vital in the production of steel. The process of smelting iron ore alongside coke yields high-quality steel crucial for construction and manufacturing.
• Cement Manufacturing: Coal provides the requisite heat in the kilns essential for making cement.
• Liquid Fuels: Through liquefaction processes, coal is converted into liquid fuels, serving as alternatives to oil-based fuels.
