Carbonisation refers to the heating of wood at high temperatures under oxygen-poor atmospheric conditions. The natural resins and moisture in the wood have fully evaporated. The remaining lignin becomes charcoal. The finished charcoal is characterised by high calorific value, easy ignition and long burning time. Charcoal is an excellent fuel and gas purification material, etc.
Carbonisation is divided into two main stages: drying and high temperature carbonisation. In the drying stage, the wood is heated to fully evaporate the moisture and resin in it. In the carbonisation stage, the wood is placed in an airtight carbonisation furnace, thereby raising the temperature inside the furnace so that the wood undergoes a full chemical reaction and is converted into high-quality charcoal.
Carbonisation furnaces use a flame for carbonisation. The furnace is equipped with an intelligent control system, which provides easy operation and high productivity. The wood is burned and in the absence of oxygen, the combustion process fully carbonises the charcoal to become charcoal. Carbonisation can be carried out by using pyrolysis reaction, and pyrolysis is carried out at high temperature to get high quality finished charcoal.
The above is about the principle of wood carbonisation. Through the mature carbonisation technology, ordinary wood is transformed into high-quality charcoal material. Charcoal can be widely used in barbecue, water purification materials, smoke purification materials and other industry fields.
