A horizontal charcoal furnace is a high-performance device designed for efficient and eco-friendly industrial carbonization. It features an innovative horizontal structure, integrating precise temperature control technology and an energy-saving combustion system. It can efficiently produce charcoal from wood, bamboo, sawdust, coconut shells, and other materials.

With a daily processing capacity of 900-3000 kg (12-14 hours per batch), it meets the needs of small to large-scale production. This furnace is widely used in biomass charcoal production, activated carbon manufacturing, metal heat treatment, and chemical raw material processing.

The horizontal carbonization furnace features a sealed, heat-resistant structure consisting of an outer shell, inner lining, pipelines, and a flue gas purification system. These components work together to ensure uniform and stable carbonization.

With an efficiency of over 95%, the furnace offers high thermal energy utilization, a short production cycle, and an excellent charcoal yield. Its stable performance, easy operation, low energy consumption, and high output make it highly popular among charcoal production enterprises.

Application of horizontal charcoal furnace

The horizontal charcoal furnace, also known as the log charcoal furnace or horizontal charcoal making machine, is a highly versatile and efficient carbonization solution.

Designed for industrial-scale production, it converts various biomass materials—such as wood chips, sawdust, and agricultural waste—into high-quality charcoal or biochar through a controlled carbonization process.

• Agriculture & forestry – Utilized for processing agricultural and forestry residues into biochar for soil improvement and carbon sequestration.
• Environmental protection – Helps reduce waste by converting biomass into eco-friendly charcoal, supporting sustainable energy solutions.
• Commercial charcoal production – Ideal for businesses requiring large-scale, high-efficiency carbonization to produce charcoal for fuel, activated carbon, or industrial applications.

Here are some photos showing the carbonization results of the products.

To meet diverse carbonization needs, we also offer continuous carbonization furnaces, vertical airflow carbonization furnaces, and other specialized models.

How does the horizontal charcoal making machine work?

• Biomass loading. Biomass materials are loaded into the horizontal charcoal furnace.
• Ignition and heat generation. The furnace is ignited, generating heat within the chamber and initiating the carbonization process.
• Temperature control. The temperature is generally controlled at about 600℃.
• Even heating. The horizontal layout ensures even heating of the biomass materials.

• Release of gases and volatiles. Evolved gases and volatile components are released during this phase.
• Controlled airflow. Controlled airflow is maintained within the horizontal furnace.
• Efficient removal. This ensures the efficient removal of moisture, volatile substances, and other impurities from the biomass materials.
• Gradual transformation. The materials undergo a gradual transformation, turning into high-quality charcoal.

Advantages of the horizontal design

• Optimal airflow. It also provides optimal airflow, which is crucial for the efficient removal of impurities and the production of high-quality charcoal.
• Uniform heat distribution. The horizontal design ensures uniform heat distribution throughout the carbonization process.

Carbonization process in log charcoal furnace

The carbonization process in a log charcoal furnace follows a structured sequence to ensure efficient and controlled charcoal production. By utilizing a well-designed system, the furnace effectively converts raw materials into high-quality charcoal through a cyclic combustion process.

• Loading the raw materials
  • Log sections and branches are carefully arranged within an iron frame, which is then smoothly pushed into the furnace cavity using a conveyor track.
  • Alternatively, coconut husks, broken branches, and other biomass materials can be directly loaded into the furnace barrel of the horizontal charcoal furnace.

• Sealing the furnace
  • The cover of the airflow horizontal charcoal furnace is securely closed.
  • Any gaps near the cover are sealed with mud or insulation cotton to prevent air leakage and ensure an airtight environment

Ignition and initial heating

• A gasification furnace is used to ignite the fuel in the ignition port at the bottom of the furnace.
• As the fuel burns, the temperature inside the furnace gradually increases.

Monitoring temperature and gas circulation

• The furnace thermometer is closely monitored. When the temperature reaches around 400°C, the gasification furnace is turned off.
• At this stage, the combustible gas produced inside the carbonization furnace undergoes cyclic combustion, reducing the need for external fuel.

Final carbonization and charcoal formation

• The carefully regulated heating process ensures effective transformation of raw materials into high-quality charcoal.
• The controlled airflow and heat distribution contribute to a consistent and efficient carbonization process

By following these systematic steps, the log charcoal furnace maximizes fuel efficiency, minimizes waste, and ensures high-output charcoal production, making it an ideal solution for commercial carbonization needs.
