Vertical Carbonization Furnace
The vertical carbonization furnace is used to convert biomass materials such as wood, coconut shells into charcoal through carbonization, which has fast carbonization, high carbonization rate, no smoke. The carbonization furnace is environment friendly and efficient and ideal equipment for making high quality charcoal. It is is widely used in agriculture, industry and daily life.
The vertical carbonization furnace is used to carbonize wood or other biomass. This machine adopts advanced thermal cycle carbonization process, which has fast carbonization, no smoke, and greatly improves the carbonization rate, making it an ideal choice for making high-quality charcoal. This carbonization furnace is often used in the charcoal production line.
The Structure of Vertical Carbonization Furnace
Vertical Chamber: The main body of the vertical carbonization furnace is a tall, cylindrical chamber where the carbonization process takes place vertically. This chamber is made of heat-resistant materials like steel.
Heating System: Heat is provided to the chamber to initiate the pyrolysis process.
Airflow Control System: To ensure proper carbonization, the carbonization furnace needs to control the airflow. In the vertical carbonization furnace, airflow is often regulated through vents or dampers located at different levels of the chamber. This allows for the adjustment of oxygen levels inside the chamber to optimize the pyrolysis process.
Collection and Exhaust System: As the biomass undergoes pyrolysis, volatile gases and other byproducts are released. These gases need to be collected and either utilized as a fuel source or properly disposed of. The exhaust system can remove these gases safely.
Feeding System: Biomass materials are fed into the top of the carbonization furnace chamber through a feeding system. This system may consist of a hopper or conveyor belt to continuously introduce the raw material.
Discharge System: Once the carbonization process is complete, the finished charcoal needs to be removed from the carbonization furnace. A discharge system at the bottom of the chamber allows for the removal of the finished charcoal.
Working Principle of Vertical Carbonization Furnace
The vertical carbonization furnace adopts a vertical structure, and the biomass material enters from the top. The carbon-containing wood materials or biomass are heated in the anoxic environment and high temperature conditions in the furnace, and the organic matter in the biomass is decomposed, and finally the charcoal is discharged from the bottom. The volatile gases formed during the carbonization process are often captured and used as fuel for the carbonization process itself, making it more efficient and environmentally friendly.
Preheating: The furnace is heated to the desired temperature to initiate the pyrolysis process. Typically, the temperature ranges from 300°C to 600°C, depending on the type of biomass and desired charcoal quality.
Pyrolysis: As the raw material heats up in the absence of oxygen, it undergoes pyrolysis, a thermochemical decomposition process. This process breaks down the organic material into charcoal, volatile gases (such as methane, hydrogen, and carbon monoxide), and other byproducts.
Carbonization: The charcoal formed during pyrolysis settles at the bottom of the chamber, while the volatile gases rise and are collected or exhausted.
Collection and Discharge: Volatile gases are collected or exhausted, while the finished charcoal is discharged from the bottom of the furnace once the carbonization process is complete.

Features of Vertical Carbonization Furnace
- 1. Vertical Design: The vertical orientation allows for efficient heat distribution and uniform carbonization of biomass materials throughout the chamber.
- 2. Compact Footprint: Vertical carbonization furnace has a smaller footprint compared to horizontal models, making them suitable for installations where space is limited.
- 3. Efficient and Energy Saving: The vertical carbonization furnace incorporates energy-efficient designs and insulation materials to minimize heat loss and reduce energy consumption during operation to achieve high-efficiency utilization of the carbonization process.
- 4. Short Production Cycle: Using three internal furnaces for alternating carbonization and separate external natural cooling, the entire production cycle is directly shortened by 2/3, which greatly improves production efficiency and saves production time.
- 5. No Pollution: Zero smoke and dust emissions. The furnace is equipped with a complete closed purification system. The entire carbonization process has no emissions, clean production and environmental protection.
- 6. Automated Control System: Advanced model can adjust various parameters, ensuring consistent and high-quality charcoal production.
Application of Vertical Carbonization Furnace
Charcoal Manufacturers: Vertical carbonization furnace is the main equipment of charcoal manufacturers. It is commonly used to convert biomass feedstocks such as wood chips, sawdust, coconut shells, and rice husks into carbonized charcoal. These charcoals can be used for various purposes such as barbecues, stove heating, cooking and industrial production.
Rural Energy Utilization: In rural areas, vertical carbonization furnaces can provide local residents with renewable energy for cooking, heating, lighting and other needs. Carbonized charcoal can be also used to improve soil, increase soil fertility, and promote crop growth.
Industrial Use: In addition to charcoal production, vertical carbonization furnace can also be used to produce other carbonization products, such as activated carbon. Activated carbon is widely used in water treatment, air purification, chemical industry, medicine and other fields.
