The Charcoal is a solid, fragile and porous combustible material with a high carbon content (around 80%). It is produced by heating wood and plant waste, to temperatures between 400 and 700 ° C, in the absence of air.
The calorific value of charcoal ranges from 29,000 to 35,000 kJ/kg and is well above the timber, of between 12,000 and 21,000 kJ/kg.
Coal is the first carbon material used by man and its use probably dates from the same time they began to use fire-charred wood that would in some bonfires.
Charcoal is mainly used as a fuel, not only for domestic use but also industrial use.
The calorific value is 3500-4500 lcal/kg.
