What Is Charcoal Carbonization?

Charcoal carbonisation is the process of taking organic-rich materials such as wood. It is converted into charcoal through a high temperature pyrolysis process. Moisture and volatile components can be removed. Solid carbon with high calorific value, low ash content, porous, hard and strong adsorption can be obtained. The finished carbon after carbonisation can be applied to baking, water purification, gas purification, furnace charge, fuel and so on. Charcoal carbonisation requires the use of a wood charcoal carbonisation furnace. The main purpose is to control the carbonisation temperature, the material is pyrolysed under oxygen-poor conditions. So that the organic material carbon elements gradually form charcoal.

The chemical reaction mechanism of charcoal carbonisation is responsible for the material-chemical process. It can be mainly divided into three stages: preheating, carbonisation and cooling.

What Is Charcoal Carbonization?

Preheating stage

Firstly, the carbonisation furnace is started by PLC. Then heat the air inside the furnace body with charcoal, coal, electric, natural, etc.. So that the temperature of the furnace body rises gradually. Thus preheating the material. Evaporate the moisture and other volatile substances in the wood raw materials. Thus realising raw material drying and drying. At the same time reduce the gas emissions of the carbonisation process. Wood raw materials which hold hate moisture and volatile organic compounds. Therefore, they need to be dried and de-ashred. According to different raw materials, the pretreatment temperature and time are different. Take wood as an example. It needs to be dried first. Reduce the moisture content to less than 10%.

Carbonisation process

When the furnace temperature reaches a certain temperature is. The volatile organic compounds in the wood raw material begin to decompose. Combustible gases such as methane and carbon monoxide are produced. The solid part of the raw material also begins to carbonisation reaction. Eventually, carbonaceous solid fuels such as charcoal are formed. In the process of carbonisation, parameters such as material temperature and carbonisation speed need to be strictly controlled. This ensures that the carbonisation is completed with a high quality product.

Cooling Stage

After carbonisation, the volatile substances in the wood will be completely released. Only high quality and pure charcoal remains. The finished charcoal then passes through the cooling system. It is then cooled and discharged.
