The continuous carbonization furnace converts wood chips, sawdust, and other biomass materials into charcoal through oxygen-limited pyrolysis. With continuous feeding, carbonization, and cooling, it is designed for stable commercial charcoal production.
Raw Materials, Charcoal Products & Applications
The continuous carbonization furnace is suitable for biomass materials that have been properly crushed and dried, including:
Wood Chips | Sawdust | Wood Shavings | Bamboo Waste | Coconut Shell Particles | Other Biomass Materials
After carbonization, the main product is charcoal powder or carbonized biomass. It can be further processed into different commercial products according to the customer’s market:
- Barbecue charcoal – briquetted and processed for grilling fuel.
- Hookah/shisha charcoal – further processed into suitable shapes for the hookah market.
- Industrial fuel – directly supplied to chemical plants, power plants, and other industrial users as fuel.
- Briquette fuel – combined with a briquette machine to produce shaped biomass charcoal products.
This makes the machine suitable for biomass charcoal production, barbecue charcoal production, hookah charcoal production, and industrial biomass fuel processing.
Working Principle & Main Structure
The continuous carbonization furnace uses oxygen-limited thermal decomposition to convert prepared biomass into charcoal. After entering the furnace, the material is continuously heated and carbonized inside a sealed rotating drum. The main structure includes the following sections:
① Feeding Conveyor
A screw feeding conveyor continuously sends biomass into the furnace. The enlarged feed inlet accommodates different material sizes, while the enclosed design helps prevent foreign materials from entering and reduces material blockage.
② Carbonization Furnace
The main furnace performs oxygen-limited pyrolysis and produces carbonized charcoal. Its core consists of the rotary drum and heating section. High-temperature rock wool insulation improves heat retention, while good sealing helps maintain the oxygen-limited carbonization environment.
③ Combustion & Heating System
The combustion section supplies the heat required for continuous carbonization. The heating and combustion sections work together to maintain the required carbonization temperature.
④ Gas Purification Equipment
Combustible gases generated during carbonization are purified through an air-purification system using materials such as peanut shells and wood shavings as the purification medium. Compared with water-based purification, this design helps avoid blockage, reduce wastewater discharge, and lower environmental impact. The purification material can be replaced approximately every six months under the supplied design.
⑤ Cooling Discharge Conveyor
The discharge conveyor uses a double-layer structure with internal water circulation to cool the charcoal after carbonization. This reduces the risk of hot charcoal contacting oxygen and catching fire during discharge.
Why Choose a Continuous Carbonization Furnace?
Continuous Production
Unlike batch carbonization, the machine is designed for continuous feeding and continuous charcoal discharge, making it suitable for commercial-scale production.
Stable Carbonization
The sealed rotary drum provides a controlled oxygen-limited environment, helping biomass undergo consistent thermal carbonization.
Efficient Heat Utilization
The insulated carbonization drum reduces heat loss and helps maintain the required temperature during operation.
Safer Charcoal Discharge
The water-cooled discharge conveyor lowers the temperature of newly carbonized charcoal before it is exposed to air, reducing the risk of spontaneous ignition.
Reduced Wastewater
The supplied gas purification design uses a dry purification medium instead of conventional water purification, helping reduce wastewater generation and avoiding water-system blockage.
Integrated Production System
The continuous carbonization furnace can be equipped with feeding, cooling discharge, gas purification, and explosion-proof devices to form a complete continuous carbonization system.
Continuous Carbonization Furnace Specifications
Different furnace sizes are available according to the required production capacity:
| Modell | Veselheid | Motorvärme |
|---|---|---|
| 800 | 200–300 kg/h | — |
| 1000 | 400–500 kg/h | 20 kW |
| 1200 | 500–600 kg/h | 25 kW |
The overall equipment range is listed at approximately 200–800 kg/h, with the complete system occupying about 12 × 4 × 4 m and weighing approximately 11 tons. Actual output depends on raw material type, moisture content, particle size, and operating conditions.
What Should You Consider Before Buying?
Selecting a continuous carbonization furnace requires more than choosing a capacity model. The following information helps us recommend the right configuration:
- Raw material: Tell us whether you will carbonize wood chips, sawdust, bamboo waste, coconut shell particles, or another biomass.
- Moisture content: Biomass should be properly prepared before carbonization. Moisture directly affects heat consumption and carbonization efficiency.
- Required capacity: Choose a furnace capacity that matches your upstream drying and briquetting equipment and your target charcoal output.
- Final product: Tell us whether you plan to produce industrial fuel, barbecue charcoal, hookah charcoal, or charcoal briquettes. This affects the recommended downstream equipment.
- Available space: The furnace system requires sufficient space for feeding, carbonization, cooling discharge, and purification equipment.
Customer Applications
Our continuous carbonization equipment has been used for different biomass charcoal projects:
- UK: Carbonized wood chips are supplied directly to a power plant as industrial fuel.
- Indonesia: The customer carbonizes sawdust and further processes the charcoal into hookah/shisha charcoal.
- Uganda: Carbonized wood chips are further processed into honeycomb charcoal briquettes.
These applications demonstrate that carbonized biomass can be sold directly as industrial fuel or further processed into higher-value charcoal products.
