SIMEC Rotary Charcoal Furnace adopts Anaerobic Destructive Distillation technology. It is designed for continuous pyrolysis carbonization. Our technology benefits industrial production of charcoal.

Biomass Charcoal is the main product of pyrolysis carbonization. Meanwhile, there’re also three byproducts, namely Combustible Gas, Pyroligneous Acid and Tar.

All the products of pyrolysis carbonization have a wide range of uses.

Comparing with biomass raw material, Biomass Charcoal is stable, non-toxic. Its combustion does not produce a large amount of flue gas. And charcoal is not easy to degrade in nature. So charcoal is more convenient for transportation, storage and use. Charcoal can be used as clean solid fuel to replace coal. Charcoal can also be used for metal smelting, manufacture of activated carbon, carburant, carbon disulfide, gunpowder, solid lubricant, electrode carbon, feed additives, art & craft work, etc. Besides, charcoal can also be used as a soil amendment to improve soil fertility, regulate soil pH and increase crop yield.

Pyroligneous Acid, also called wood vinegar or wood acid, is a dark liquid produced by the destructive distillation of wood and other plant materials. Pyroligneous acid can be used for the preparation of acetic acid, acetate and other chemicals, which have a certain purpose in agriculture, livestock breeding, skin care beauty, health care and other fields.

Tar can be used for processing creosote, binder and other products, being used in synthetic rubber, chemical, pharmaceutical and other industries.

In order to improve the economics of the pyrolysis system, SIMEC biomass pyrolysis carbonization technology is based on the cogeneration of carbon-gas or carbon-liquid-gas.  At the same time, the production of biomass charcoal is combined with high grade gas or high added value liquid by-products.



Combustible Gas consists of methane (CH4), ethylene, carbon monoxide (CO₁), etc. being generated by pyrolysis carbonization. It can be recycled and purified to be qualified fuel for gas burners which provide heat for charcoal furnace.

Extra combustible gas can be used to generate electricity power through power generation unit. SIMEC is working on the R&D of compact power generation system which is capable enough to provide electricity for pyrolysis carbonization system. So the scope of charcoal project location will be expanded. As long as the location is close to raw material and road, then it’ll be suitable to build a charcoal factory. No need to consider power supply from state grid, no need to pay for electric power.

With the combustion of combustible gas, high temperature flue gas can be recycled to dry green raw material which has a very high moisture content. Feedstock of charcoal furnace needs to have moisture 15%-20% or less to guarantee carbonization efficiency. SIMEC has waste heat recovery technology for biomass drying purpose.

Generally speaking, SIMEC pyrolysis carbonization technology is developed to maximize the value of biomass raw material. Automatic Rotary Charcoal Furnace is absolute environment friendly equipment, energy-saving and free-emission.

Test Run Video of Rotary Charcoal Furnace:

SIMEC automatic rotary charcoal furnace is complete carbonization plant to process the biomass raw materials, such as sawdust, PKS (palm kernel shell), coconut shell, chicken litter, rice husk, peanut shell, crop stalk, log bark, sunflower shell etc, to be CHARCOAL with high fixed carbon via anaerobic destructive distillation.
 
Working Principle:
The whole system consists of biomass gasifier, gas purifier, fan, burners, carbonization furnace, etc. This equipment is adopted with dry distillation carbonization technology. The combustible gas, carbon monoxide, methane, hydrogen, generated during the carbonization is purified by the gas purifier, from which wood tar and pyroligneous acid as the by products are separated. The complete combustible gas heats up the carbonizing furnace through the self-air distribution burners.
 
Requirement on Biomass Raw Material:
size less than 25mm, moisture content less than 15%-20%
