Charcoal, a fuel with a rich history. It still occupies an important position in our daily life. Charcoal has the advantageous characteristics of high combustion heat and long-lasting combustion process. It brings convenience to our life. Charcoal is a common carbon source, which is a solid fuel and is obtained after heating treatment. Charcoal making machines are important equipment for making charcoal. It is mainly composed of organic materials such as wood. Charcoal has high calorific value and stability. Therefore, it is widely used in barbecue, smoking, boiler burning and other industrial production.

What Is The Theory Of Charcoal Production?

Theory of wood making charcoal

The principle of wood making charcoal is by heating the wood. So that its internal moisture and volatile organic compounds gradually evaporate out. At the same time in the lack of oxygen under the conditions of pyrolysis and cracking reaction, so as to form charcoal.

Drying Stage

In the eat-up stage of heat treatment, the moisture in the wood is heated and evaporated. When the temperature rises to 100°C, the moisture in the wood completely evaporates.

Pyrolysis Stage

When the moisture in the wood is completely evaporated, the organic matter in the wood begins to crack. Under oxygen-poor conditions, the organic matter is broken down into a series of volatile organic substances (VOCs) and residues from the carbonisation of the wood. These VOCs enter the air and wood residues gradually form wood char.

Carbonisation Stage

In an oxygen-poor atmosphere, the charcoal from the wood is oxidised at high temperatures and the oxidised charcoal reacts with the surrounding gases at high temperatures to form a hard substance. This is charcoal. Because of its special structure, charcoal will not be disintegrated by organisms in nature or by natural oxidation. Therefore charcoal is very stable and is not easy to decompose when kept for a long time.

By understanding the theory of making charcoal from wood, we can have a better grasp of how charcoal is made. The made charcoal has high calorific value and stability and is widely used in various fields.
