Raw Materials For Making Charcoal Briquettes

The most common materials are coconut shell, sawdust, woodchips, bamboo shavings, tree bark, chestnut shell, cotton stalk, sesame stalk, corn stalk, sunflower stalk, soybean stalk, rice husk, sugarcane bagasse, corncob, etc. The material diameter must be less than 6mm and moisture is about 10%. The raw material piled density is 60-350 kg/m³, while the briquettes piled density is 1100-1400kg/m³. We can easily draw a conclusion that the briquettes density has greatly improved, so the combustion value also improves 30%-40%. After carbonization, the charcoal briquettes calorific value is 7000-8500 kilocalories. The burning time is 200 min/kg and carbon content is 75%-85%.
