The main raw material for charcoal is wood. Various different types of wood can be used to make charcoal, such as: branches, trunks, sawdust and other by-products of forest felling or wood processing. Woods such as hardwood, oak, walnut, and cherry are preferred for making charcoal, which is characterised by advantages such as high density, easy ignition, and long burning time. The process of converting wood to charcoal is a chemical reaction known as pyrolysis. Wood is heated to a high temperature in an oxygen-poor environment, and the moisture and volatile organic compounds contained in the wood evaporate, leaving behind charcoal. The carbonisation process involves controlling the temperature and oxygen supply in order to achieve the desired quality of finished charcoal.

The Process Of Making Charcoal From Wood

1. Stacking The Wood: The first step in making charcoal is to place the wood in the carbonisation furnace. The wood is placed as tightly as possible.
2. Heating The Wood: A fire is started at the bottom of the furnace to raise the carbonisation temperature. The inside of the furnace starts to burn up.
3. Pyrolytic Carbonisation: The whole process requires strict control of the carbonisation temperature and the amount of oxygen supplied. This prevents the wood from burning excessively. Control the amount of feed inside the furnace body, volatile substances will not react with oxygen, compressed air can accelerate the formation of volatile substances. Controlling the reaction temperature can make the moisture and volatile organic matter in the wood volatile material, so as to form the form of carbon. If the carbonisation temperature is too high, the production of charcoal will also increase and the wood will also be burnt.
4. Collecting The Charcoal: After the wood is converted into charcoal, wait for the charcoal to cool down and then remove the charcoal from the carboniser and remove the carbonised residue.
