Production Process of Straw Bio-carbon

Straw burning has become a public enemy of the environment. With the improvement of agricultural mechanization level in China, straw can not only be used for taking fire, cooking and feeding cattle and sheep, but also can be carbonized into straw charcoal for wider applications.

Straw Charcoal Plant

If you want to carbonize straw into charcoal, you need to use carbonization furnace and equipment. The charcoal carbonized from straw is called bio-carbon, which is mainly used to improve the soil, fertilizing soil fertility, repair farmland, as well as improve the yield and quality of crops. The production process of the bio-carbon is: ignite the combustible materials (such as straw, sawdust, rice husk, corn stalks, coconut shell and other biomass) in the carbonizing furnace firstly; when the flue gas generated after combustion finishes spraying, cooling, purification and other processes, the resulting combustible gas (carbon monoxide, methane, ethane, etc.) is recycled as the heat source of pre-carbonization to heat and dry the materials in the first and second carbonized tube inside the carbonization machine, and then third, fourth carbonized tube. The flue gas generated in the carbonization process is through spray, cooling, purification and other processes, and then make the resulting combustible gas for second combustion. In such as manner, using the heat generated by itself to burn itself can carbonize the eco-friendly biological carbon powder. This technology can make the crop straw, rice husk, tree branches, weeds, corn stalks and other agricultural and forestry waste carbonized into carbon powder by carbonation furnace and further processed into activated carbon and a series of fuels, with the characteristics of safe, environmental protection, easy to burn, high calorific value, renewable and so on. It is beneficial for domestic life fuels and commercial energy, and the products can also be exported.

The straw charcoal plant has the characteristics of unique structure, advanced carbonation technology, short cycle, high yield, environmental protection, long service life. The whole carbonation process doesn’t emit soot and doesn’t have any pollutant. The various final products don’t produce carbon monoxide, carbon dioxide or other pungent gas, which is especially suitable for enterprises of small and medium production-scale to use.
