development of coal briquettes Indonesia has sufficient raw materials for long-term production of briquettes, coal briquettes are solid fuel made from coal mixed with clay and binder, the advantages of coal briquettes 1. cheaper price 2. high heat and continuous 3. no risk of explosion 4. not noisy 5. abundant coal raw materials. application of coal briquettes 1. heating chicks 2. food industry 3. boiling shells 4. salt industry 5. drying tobacco 6. burning coal 7. mushroom cultivation 8. restaurant. there are two types of coal briquettes 1. carbonation briquettes, carbonated briquettes are briquettes in which the coal is carbonized before being processed into briquettes, the carbonation process aims to reduce flying substances in the coal, so that the final product is odorless and smokeless, known as super briquettes 2. briquettes non-carbonated, non-carbonated coal briquettes were developed to produce coal briquettes that are cheaper but still safe, complete combustion is a process where all the volatile matter that emerges from the briquettes will be completely burned.
