A hard, porous, highly carbonaceous product formed during the heating of wood without access
(or with limited access) of air in furnaces and retorts (sometimes in
campfires as well).
Depending onthe type of wood, 1 m3 yields 140-180 kg of coal, 280-400kg
of liquid products,
and nearly 80 kg offuel gas. The heat of combustion of wood charcoal is 30,000-35,000 kJ/kg
(7,000-8,100kcal/kg). The density of birch coal is 380 kg/m3. Pines
(300kg/m3) and spruces (260kg/m3) yield less densecoal.
The high porosity of wood charcoal is responsible for its significant adsorption properties. At normaltemperature wood charcoal is capable of combining with the oxygen in air; this is the reason forcases of spontaneous combustion of wood charcoal. The moisture content of wood charcoalunloaded from furnaces and retorts is 2-4 percent. During storage, the moisture content rises to 7-15 percent. The ash content of charcoal should not exceed 3 percent and the content of volatiles,not more than 20 percent. A distinctive feature of wood charcoal is the low content of suchadmixtures as phosphorus and sulfur, which makes it indispensable in some metallurgicalprocesses.
Wood charcoal is widely used in the production of crystalline silicon, carbon disulfide, activated
carbon, and electro
carbon articles and as fuel for domestic use.
As global crude oil prices continue
to rise, kerosene and cooking gas have become expensive and unaffordable for
many ordinary people in developing countries. For millions of Africans who
need heat energy (or fire) to cook their daily food, wood remains the easiest
and cheapest source of fuel.
According to the United Nations
Environment Program (UNEP), firewood and charcoal alone provide more than 40
percent of energy used in Africa.
In fact, around 80 percent of
households on our continent depend on wood and charcoal as a primary
energy source.
Due to its desirable qualities,
Africans use more than 23 million tonnes of charcoal every year,
making it a multi-billion dollar industry.
Charcoal is an exportable commodity
and we have the capacity and are willing to export it to any country in the
world.
