Thermal Coal vs. Metallurgical Coal: Know the Difference
By Shumaila Saeed || Updated on December 26, 2023
Thermal coal is used primarily for power generation due to its high burn rate, while metallurgical coal is essential in steel production for its coking properties.
Key Differences
Thermal coal is primarily used in power plants to generate electricity, whereas metallurgical coal is used in steel production as a reducing agent.
