How Does Beston Group Address Technical Challenges in Turning Sawdust into Charcoal?

Challenge One: Small Particle Size

Sawdust typically has much smaller particles compared to wood blocks or larger wood fragments. This characteristic complicates their handling. Smaller particles can result in difficulties in sealing and gas flow, potentially leading to uneven charring during charcoal production. Furthermore, particle size inconsistency can adversely affect the quality and yield of the charcoal.

Challenge Two: Lightweight Nature of Sawdust

Another challenge is the lightweight nature of sawdust, making it prone to scattering and waste during transportation and processing. This may result in particle loss, not only wasting the raw material but also increasing the risk of environmental pollution.

Beston’s Innovative Solution: Horizontal Rotary Pyrolysis Reactor

Beston has introduced an innovative solution to address these challenges in the conversion of sawdust into charcoal. They have implemented the Rotary Hearth Furnace technology, which represents a significant advancement in this regard. The key feature of this furnace type is its adaptability to the small particle size and lightweight nature of sawdust. Key Features include:

  • Precise Temperature Control: The Rotary Hearth Furnace allows for precise temperature control to accommodate varying sawdust particle sizes. This helps ensure a uniform temperature distribution throughout the charcoalization process.
  • Effective Gas Circulation: This furnace type optimizes gas circulation to ensure complete charring of sawdust, thereby enhancing charcoal yield and quality.
  • Prevention of Scattering: This furnace type is designed with effective locking and sealing mechanisms to prevent sawdust from scattering during the process, reducing waste.

How to Make Charcoal from Sawdust

The working process of the sawdust charcoal making machine is as follows:

1. Pretreatment

To ensure a smooth and efficient pyrolysis reaction, sawdust raw materials should be less than 15% moisture and less than 20mm in size(5-8mm is the best). Otherwise, a dryer or crusher is needed.

2. Feeding

Sawdust is loaded to the silo by the loader and then is fed into the inner cylinder of the pyrolysis(carbonization) reactor by a screw feeder.

3. Pyrolysis(Carbonization)

Heat the reactor for 60-90 minutes. At around 150℃, sawdust will begin to decompose. At around 350℃, charcoal will continuously be produced. Typically, this reaction takes approximately 15-20 minutes.

4. Cooling discharging

The produced charcoal falls from the inner cylinder of the pyrolysis reactor into the outer cylinder. And then it is discharged safely by the water-cooling screw auto discharger. Its temperature will be reduced to below 45℃.

Syngas recycling

There are syngas generated during biomass pyrolysis. The syngas are delivered to a cyclone dedusting system to remove heavy particles. Finally, syngas is recycled to heat the pyrolysis reactor

Exhaust gas treatment

The hot smoke from the reactor enters the cyclone dust collector to be purified. Then the hot smoke passes through the air heat exchanger and then goes into the fuel condenser. Finally, it is sucked into the dedusting tower by the exhaust-induced draft fan. Cleaned by the cyclone, dedusting water spray, ceramic ring absorption, and the defogging plate, the exhaust gas is expelled.
