Looking for a high-efficiency biochar machine or continuous carbonization furnace? Our advanced systems deliver consistent, large-scale charcoal and biochar production with automated control and eco-friendly operation.

Working Process of Continuous Carbonization

Our continuous carbonization furnace transforms biomass waste into valuable biochar and charcoal through an automated, environmentally friendly process:

• 1. Raw material is fed into the furnace through the feeding system.
• 2. The biomass enters the carbonization chamber, where it undergoes pyrolysis.
• 3. The produced charcoal moves to the cooling zone.
• 4. Charcoal is discharged from the furnace.
• 5. Gases released during carbonization are collected, purified, and either used as fuel or safely released.

This continuous process allows for efficient and large-scale production of charcoal, with minimal manual intervention and high consistency in product quality.

Feeding System: Conveyor Belt/Screw Feeder

Transports raw biomass (wood chips, sawdust, agricultural waste, etc.) into the furnace.

Carbonization Chamber:

Inside the carbonization furnace, the organic materials undergo pyrolysis, which is the thermal decomposition of organic compounds in the absence of oxygen. This process occurs at elevated temperatures, usually between 400°C to 600°C, depending on the material and desired end product.

Heating and Carbonization:

The carbonization chamber is heated through external heating and internal combustion process.

The combustion system heats the kiln to temperatures of 400-600°C, producing hot gases that pass through the biomass material. When the material is heated, volatile gases, tar, and other by-products are released. These gases are typically collected and can be used as fuel for heating or for other purposes.The remaining solid residue undergoes carbonization, transforming into charcoal.

Cooling and Collection:

After carbonization, the charcoal enters the cooling system from the furnace for cooling to avoid spontaneous combustion and prepare it for discharge.The temperature of the charcoal powder quickly drops from about 400°C to about 20-30°C, and can be discharged and bagged.

Gas Collection and Purification System:

Gas Collection Pipes: Collect gases released during the carbonization process.

Cyclone Separator: Removes particulate matter from the gas stream.

Condenser: Cools and condenses tar and other volatile compounds from the gases.

Gas Purification Unit: Further cleans the gases, which can then be used as fuel for the heating system.
