Charcoal briquettes are a high-quality fuel and can also be used in the production of crystalline silicon to replace part of the lump charcoal. Briquettes have high mechanical strength (6.9-9.8 MPa), increased density (0.9-1 g/cm3), high calorific value (30,000-32,000 kJ), and low hygroscopicity. Charcoal briquettes are a modern high-calorie biofuel produced using special equipment from charcoal screenings using the pressing method. The plant origin of the raw materials provides this fuel with exceptional environmental friendliness when used in any required quantity. Charcoal fuel briquettes are the same charcoal, only compressed. Food starch is used as a binder. A positive aspect when using charcoal briquettes as fuel is their minimal impact on the environment during combustion compared to classic solid fuel (no slag, increased smoke, and other carcinogenic substances). They combine all the advantages of charcoal, while having undeniable advantages.
