In recent years, wood charcoal making machines have gradually become a mainstream solution for recycling waste wood. The machine uses pyrolysis technology to convert waste wood into valuable charcoal. Therefore, the machine fills the gap in sustainable recycling options for waste wood. In addition, due to its wide range of uses, charcoal is also of high economic value. Because it combines sustainability and profitability, wood charcoal machine is gradually becoming the investment choice for recyclers.

What is Wood Charcoal Making Machine?

Wood charcoal making machine works on the principle of biomass pyrolysis. In a microaerobic high-temperature environment, organic substances such as cellulose, hemicellulose, and lignin in wood decompose into charcoal and combustible gas. The machine consists of feeding system, reactor, discharging system, flue gas treatment system, and emission control system. The integrated machine configuration enables efficient and clean production of charcoal. Therefore, wood charcoal making machine has become the best choice for waste wood reduction/resource utilization.

Modern Wood Charcoal Machine Vs. Traditional Charcoal Kiln

At present, there are two methods of making charcoal, traditional charcoal kilns and modern wood to charcoal machine. However, the traditional charcoal kilns are unfriendly to the environment. That’s why you may need to choose modern biochar equipment to produce charcoal. Below is a comparison of the two production methods.

Type Modern Wood Charcoal Machine Traditional Charcoal Kilns
Production Efficiency
  • Large-scale production
  • Produce large amounts of charcoal in a short time
  • Small-scale production
  • Long production cycle
Automation Degree
  • Automated control enables continuous production
  • Low labor cost
  • Rely on manual operation
  • High labor cost
Environmental Impact
  • Equip emission control facilities to reduce environmental impact
  • High energy utilization efficiency reduces fossil energy consumption
  • Direct discharge of pollutants causes environmental pollution
  • Consumes a lot of fuel and has low energy efficiency
Charcoal Quality
  • Controllable operating parameters ensure quality consistency
  • Dust collection system minimizes charcoal impurities
  • Consistency and shape vary widely
  • Lower quality, more impurities

Workflow of Wood Charcoal Machine

Wood Pretreatment

The feed size of the wood should be less than 20 mm (5-8 mm is optimal). In addition, its moisture content should be less than 15%. We provide wood pretreatment equipment such as crushers and dryers. The wood that meets the feeding conditions enters the main furnace for reaction.


Wood Pyrolysis

The wood biochar making reaction is carried out in a low oxygen and micro-pressure environment. The reaction temperature is 380°C to 450°C. During this process, the wood undergoes dehydration, demethylation, and volatile release. Finally, wood charcoal is discharged through the water-cooled discharge system.


Combustible Gas Recovery

The biogas generated by the reaction undergoes dust removal and condensation treatment. It can ensure the cleanliness of gas. The combustible gas obtained after treatment enters the combustion system. The combustible gas then provides a heat supply to the entire machine.


Emissions Treatment

The machine is equipped with dust removal equipment at multiple locations. The waste gas generated by the reaction is discharged after cooling and dust removal. In addition, the exhaust gas treated by a high-end exhaust gas treatment system (optional) can meet EU emission standards.


Wood Charcoal Test Report for Reference

The quality of charcoal is the main factor in judging the performance of the wood biomass pyrolysis plant. The fixed charcoal in the charcoal produced by the machine can reach about 65%. In addition, it has higher purity and better calorific value. Below is a sample test report for your reference.

Applications of Wood Charcoal

As a versatile material, wood charcoal has a wide range of applications in various fields. The charcoal produced by the wood pyrolysis plant can fully meet the standards of biochar. Therefore, charcoal is not only a fuel with excellent combustion properties but also an eco-friendly material. The following are the main applications of wood charcoal in different fields:

Wood Charcoal for Soil Improvement

Soil Improvement

  • The application of wood biochar in farmland can improve soil structure and increase soil fertility.
  • Adding wood biochar to forest soil can promote plant growth and ecological restoration.
Wood Charcoal for Poultry&Livestock Breeding

Poultry&Livestock Breeding

  • Wood biochar can be used as a feed additive. This helps regulate the animal’s digestive system and promotes absorption.
  • It is also used as bedding material in poultry houses. This absorbs feces, reducing odor and bacterial growth.
Wood Charcoal for Carbon Removal

Carbon Removal

  • Wood biochar typically has a higher carbon content, which makes it an effective carbon storage medium.
  • It also has a good pore structure and surface activity. This makes it helpful in fixing carbon over the long term.
Wood Charcoal for Construction Material

Construction Material

  • Wood Charcoal allows long-term storage of carbon in building structures. This helps slow down greenhouse gas emissions.
  • Due to its low thermal conductivity, wood charcoal is an effective insulator. This helps improve the energy efficiency.
Wood Charcoal for BBQ Fuel

BBQ Fuel

  • Wood Charcoal has the characteristics of high calorific value and stable heat, making it an ideal fuel for barbecue food.
  • The smoke produced when charcoal burns can add a unique aroma to food, making barbecue food more delicious.
Wood Charcoal for Hookah Charcoal

Shisha Charcoal

  • Wood Charcoal provides long-lasting heat and a stable burn, maintaining a consistent smoking experience with the shisha hose.
  • The smoke produced by burning charcoal is light and pure, which helps to extract the tobacco flavor in the shisha charcoal.
Wood Charcoal for Metal Smelting

Metal Smelting

  • Wood charcoal has a high calorific value and reducing properties. It is suitable for use as a reducing agent in metal smelting processes.
  • It is often used to extract metals, such as iron, aluminum, etc. Wood charcoal helps separate metals and oxides from ores.
Wood Charcoal for Alternative Fuel

Alternative Fuel Production

  • Due to its low cost, and high combustion efficiency, wood charcoal is used as an energy source to replace traditional fossil fuels.
  • As an alternative fuel, wood charcoal can be used for heating, smelting, and energy supply in factories and industrial equipment.

Sources of Waste Wood

As the raw material for wood charcoal making machines, waste wood appears in multiple industries. They may include the cultivation and processing of wood. However, not all of this waste wood is properly disposed of. Here are some major sources:

Wood Waste from Forest

Forest Management&Harvesting

  • In forest management, some trees that do not meet commercial value criteria, such as poorly growing trees, are cut down.
  • During the forest harvesting process, there are usually some residues such as tree trunks and branches left at the harvesting site.
Wood Waste from Timber Processing

Timber Processing

  • Sawmills produce a large amount of by-products such as sawdust and wood chips during processing like sawing, planing, and grinding.
  • The process generates leftover material considered waste due to inappropriate dimensions or defects.
Wood Waste from Wood Product Processing

Wood Product Processing

Waste wood is also produced in the manufacturing process of wood products, such as furniture manufacturing, board production, etc. They include some defective products, trimming remnants, discarded parts, etc.

Wood Waste from Garden Waste Recycling

Garden Waste Recycling

Garden waste recycling refers to waste generated from activities such as landscape maintenance, and urban green space management. Most of them are waste materials such as branches and trunks collected from the tree pruning process.
