Carbonization is an important link of biomass briquette production line, which plays an indispensable role in the whole production process. The main purpose of carbonization process is to convert biomass raw materials into solid fuel with higher energy density through high temperature treatment, so as to improve its combustion performance and use value.

Carbonization is usually the last step in the biomass briquette production line. After pre-treatment, such as crushing, drying and pressing, biomass raw materials have been processed into briquettes with regular shape and high density. However, these briquettes still contain a lot of volatile substances and moisture, which will cause smoke and incomplete combustion when burned directly. Through carbonization treatment, these unnecessary components can be effectively removed, and at the same time, the fixed carbon content of the briquette can be increased, making its combustion cleaner and more efficient.

Carbonization usually needs to be carried out in a special carbonizer. Biomass briquettes are placed in a closed furnace, and the pyrolysis reaction under anaerobic or hypoxic environment is realized by controlling temperature and oxygen supply. In this process, the moisture and volatile substances in raw materials are evaporated or decomposed, and the rest are transformed into solids with high carbon content. Carbonized briquettes not only have higher calorific value, but also can be stored and transported better, and are widely used in industrial boilers, household heating and outdoor barbecue.

The development of carbonization technology has also promoted the progress of biomass energy utilization. Modern carbonization equipment pays more attention to environmental protection and efficiency, and reduces the smoke and pollutants produced during carbonization through optimized design. At the same time, some advanced technologies can also recycle the by-products produced in the carbonization process, such as wood vinegar and wood tar, which are also widely used in agriculture and chemical industry.

In a word, carbonization is a key link in biomass briquette production line, which not only improves the quality of biomass fuel, but also promotes the utilization of renewable energy, and has a positive impact on environmental protection and energy fields. In the future, with the further innovation of technology, the carbonization process will be more efficient and environmentally friendly, and provide more high-quality green energy solutions for the society.
