タイトルまたは説明

Charcoal is mainly produced from tropical hard wood, although there are other sources like coconut shell. The process of production is called PYROLYSIS. This means burning of wood under high temperature in the absence of air.
There are two methods of making Charcoal: direct and indirect.
The direct method uses heat from incomplete combustion of the organic matter, which is to become charcoal. The rate of combustion is controlled by regulating the amount of oxygen allowed into the burn and is stopped by excluding oxygen before the charcoal itself begins to burn, the indirect method uses an external heat source to cook organic matter contained in a closed but vented airless chamber (retort). This is usually carried out in a metal or masonry chamber (furnace)
