The article discusses how briquettes are made from coal to create solid, smokeless fuels for domestic use. The main goals are to convert cheap coal into usable fuel, produce smokeless fuels, and address air quality concerns. Briquettes are formed by applying pressure to small or powdered coals, with some types requiring a binder like pitch. Binderless briquettes can be made from certain types of coal, while others need a binder for production. The research shows that briquetting coal is important for creating affordable, clean-burning fuel options, especially in areas where natural gas is not readily available.
