How is smokeless fuel made?

Smokeless fuel is typically made by carbonizing coal, which involves heating it in the absence of air to remove volatile components and moisture. This process produces a solid, high-carbon product, often in the form of briquettes or pellets, that burns more cleanly than traditional coal. Additionally, smokeless fuels can be manufactured from biomass or waste materials using similar carbonization techniques, resulting in eco-friendly alternatives. These fuels are designed to minimize smoke and harmful emissions when burned.
