Raw materials of continuous carbonization furnace
For the continuous carbonization furnace, the requirements for materials differ from those processed by the hoist and horizontal carbonizing furnaces. This furnace is designed to handle softer and smaller materials, which must meet specific criteria for efficient carbonization.
Material size. All materials need to be small and thin, with a size of under 10 centimeters.
Suitable materials. The continuous carbonization furnace can process a variety of carbon-containing materials, including:
- peanut shells
- plant matter
- bark
- straw
- walnut shells
- coconut shells
- palm shells
- sawdust
The raw materials for the continuous carbonization furnace should ideally have a moisture content below 20%. If the materials exceed this limit, they should be pre-dried using a biomass rotary dryer to achieve optimal moisture levels.
Inside the carbonization furnace, high-temperature dry distillation and anaerobic carbonization processes take place, ensuring a high carbonization rate. This furnace is an excellent choice for charcoal processing plants, offering efficient, high-quality charcoal production.
Continuous carbonization furnace structure
The continuous carbonization furnace is composed of several key components: spiral and flat feeding systems, the main furnace body, condensing discharge unit, flame head, combustion pool, purification equipment, and power distribution cabinet.
During operation, the material passes sequentially through a preheating zone, a high-temperature carbonization zone, and a cooling zone to complete the carbonization process efficiently.
Ignition head of the burning pool
- The WD-CF1200 model has a total of 18 ignition devices.
- The WD-CF1200 model has a total of 16 ignition devices.

- It is insulated with a 5cm layer of high-temperature rock wool, ensuring excellent heat retention.
- Rock wool is lighter than traditional refractory bricks, making transportation easier.
- The rock wool provides superior thermal insulation compared to conventional materials.
Inside mineral wool of the carbonization furnace
- Constructed with 310s stainless steel plate and rock wool for enhanced durability.
- Provides improved sealing, reducing heat loss.
- Ensures efficient heat preservation within the carbonization chamber.
- Maintains optimal temperatures in the carbonization area, promoting consistent results.
Screw feeder and cooling discharge device
- The cooling discharge device can be connected to either a water pump or a water pipe.
- It cools the high-temperature charcoal to prevent spontaneous combustion during material discharge.
Inside structure of the screw conveyor
- The screw conveyor’s inside structure consists of a rotating screw blade.
- The screw blade is housed within a cylindrical tube.
- This design efficiently transports materials through mechanical movement.
How to carbonize rice husk in a continuous carbonization furnace?
To carbonize rice husk in a continuous carbonization furnace, follow these steps:
Preheating and ignition
- Use Liquefied Petroleum Gas (LPG) to ignite the machine.
- Preheat the furnace for about 1 hour. Around 20-30 kg of LPG is required for ignition, and it only needs to be ignited once.
- The preheating is complete when the temperature reaches between 280°-330°C.
Carbonization process
- Once the preheating temperature is reached, begin adding raw materials, such as rice husk, into the furnace.
- For rice husk, the material can be discharged once the furnace reaches a temperature of 280°C.
- Ignite the combustion chamber, and after 10-20 minutes of carbonization, observe whether hot gas is generated in the combustion pool.
- If flammable gas is produced, ignite the gas to burn in the combustion chamber.
- Once the combustion process starts, turn off the LPG burner.
Cycle and cooling
- A round of carbonization takes approximately 20 minutes, after which the material can be removed and replaced with fresh raw material for a new cycle.
- Cooling is necessary when discharging the material. The furnace has a double-layer condenser, which is filled with circulating water to cool the carbonized raw material before discharge.

FAQs of continuous carbonization furnace
What is the heating source of the sawdust charcoal-making machine?
The continuous carbonization furnace uses liquefied petroleum gas (LPG) as the initial heating source, typically consuming only 15–20 kg per cycle. After running for 1 to 1.5 hours, it begins to produce combustible gas, which can then be used to sustain ongoing operation—eliminating the need for additional LPG. This makes LPG a recommended choice for achieving both energy efficiency and cost savings.
Is the material that can be carbonized by the carbonization furnace only biomass raw materials?
Beyond biomass, the continuous carbonization furnace can also process various materials such as tin foil, aluminum foil, cans, household waste, plastics, and electronic waste. For best performance, the material size should be kept within 10 centimeters to ensure efficient carbonization.
