Stove continuous carbonization furnace

Types of Continuous Carbonization Furnace

A stove continuous carbonization furnace is an industrial device that converts organic materials into charcoal through a process called carbonization. This is done in a continuous manner, meaning that raw materials are fed into the machine, while charcoal is produced and discharged simultaneously. Such processes typically involve high temperatures in the absence of oxygen. Continuous carbonization furnaces are highly efficient and can operate for long periods without interruption. There are four main types of continuous carbonization furnaces.

• horizontal carbonization furnace

  The most popular type of continuous carbonization furnace is the horizontal one. In a typical horizontal carbonization furnace, raw materials are fed into the system from the top. They then move forward in the furnace by the push plates linked to the roller shaft. When moving forward, they are gradually dried and carbonized. Finally, the finished charcoal is discharged from the bottom.

• Vertical carbonization furnace

  In contrast to its horizontal counterpart, the vertical carbonization furnace has a smaller ground area and a larger height. This makes it relatively easier to install and manage.

  The vertical carbonization furnace works by feeding raw materials into the upper section. They then naturally fall down due to gravity in a dispersive manner. Meanwhile, heat transfers into the raw materials from the sides of the vertical furnace to dry them and carbonize them into finished charcoal. Finally, the charcoal is discharged from the bottom.

• Stacked carbonization furnace

  In a typical stacked carbonization furnace, several furnaces are put together in a stack. This allows users to process even more raw materials and produce carbonized products at a faster rate.

• Indirect heating carbonization furnace

  The indirect heating carbonization furnace is the most popular type of continuous carbonization furnace. Its typical structure includes a carbonization chamber and an external combustion chamber.

  In such devices, raw materials are put into the carbonization chamber. Then the materials are heated externally by the combustion chamber. The method of heating them indirectly ensures that there is no oxygen in the carbonization chamber while preventing the carbonized materials from being damaged.

Specifications and Maintenance of Continuous Carbonization Furnace

Specifications

• Power: Generally measured in kilowatts (KW) or tons, continuous furnaces carbonize large amounts of biomass energy and usually have a higher total power consumption.
• Fuel: The type of fuel used in continuous carbonization furnaces includes coal, wood, natural gas, biomass gas, etc. The continuous carbonization furnace's performance, efficiency, and applicability will vary depending on the kind of fuel.

Maintenance

• Regular cleaning: Clean the residual materials inside the stove regularly, such as carbon dust, ash, etc. This will prevent clogging of the ventilation ducts and circulating materials, improving the furnace's burning efficiency and carbonization quality.
• Inspect the equipment: Frequently check the components of the continuous carbonization furnace, such as the ventilation ducts, valves, water-seal tanks, and carbonization pots. Look for damage, looseness, and leakage, and repair and replace them in time if necessary to ensure the stable operation of the equipment.
• Maintain the combustion system: The burning system is the critical part of a continuous carbonization furnace. Regularly and systemically maintain the parts of the burning system, such as cleaning furnace grates, ash removal, checking fuel supply systems, and more, guarantees complete combustion and stable carbonization processes.
• Adequate ventilation: Good ventilation should be maintained around continuous carbonization furnaces to avoid high temperatures and asphyxia. This protects the safety of operators and equipment.
• Regular carbonization pot cleaning: For continuous carbonization furnaces with pots, the pots should be cleaned regularly to remove carbonization residue and ensure even carbonization.
• Regular inspection: Regularly check the seals and water levels of the water seal tanks to prevent the leakage of combustible gases and ensure their safe operation.
• Regular maintenance: Regular maintenance and repairs of the continuous carbonization furnace are required per the manufacturer's instructions. Check and repair the critical parts to ensure the equipment's stable operation.

Scenarios of stove continuous carbonization furnaces

The carbonization process in continuous carbonization furnaces can be widely applied in various industries for the benefit of the environment and the economy.

How to Choose a Stove Continuous Carbonization Furnace

When choosing a continuous carbonization stove, buyers should consider the types of feedstock compatible with the furnace. This is because different furnaces can only process specific biomass materials. In most cases, these requirements are based on the nature of the feedstock. For instance, some continuous carbonization furnaces can only accept wood as biomass, while others can process agricultural wastes. Additionally, evaluate the quality of the carbonized product that the continuous carbonization furnace produces.

It's also important to consider the continuous carbonization furnace's waste management system. Some furnaces may release waste gas that requires treatment before disposal, while others may have a system that collects the air pollution. Furthermore, the energy efficiency of the machine should be evaluated. Look for models with thermal efficiency and energy recovery systems that minimize energy losses.

Do not overlook safety features such as temperature controls, pressure relief valves, and proper ventilation. Such safety components can mitigate potential hazards. If purchasing an automatic continuous carbonization stove, check the remote monitoring and control capabilities. Such characteristics can simplify operations and provide real-time data feedback for adjustment.

Ultimately, analyzing the after-sales support services offered by manufacturers is crucial. In most cases, continuous carbonization stoves require periodic maintenance and technical assistance. Therefore, buying from manufacturers with reliable technical support, spare parts availability, and comprehensive warranties can facilitate smooth operations over time.
