Cooal
Thermal Coal
Thermal coal, has a high carbon content and significant heat energy, usually around 24-35 MJ/kg. Commonly used for coal-fired power plants.
Know More ?
Coking Coal
Coking coal has a high carbon content and low ash content, ideal for coking in steel production. It is also used in the production of ferroalloys, silica, and refining of other metals.
Know More ?
Low-Sulfur Coal
Due to its low sulfur content, this coal produces cleaner emissions, making it a more environmentally friendly choice in power generation.
