Horizontal Carbonization Furnace
The Horizontal Biomass Carbonization Furnace is the industrial standard for large-scale production of high-fixed-carbon charcoal. Designed with a high-capacity square chamber, it is the primary choice for carbonizing mechanism charcoal (sawdust briquettes) and uniform timber logs. This horizontal configuration ensures stable thermal distribution, resulting in a consistent, high-quality end product suitable for both professional catering and industrial applications.
Horizontal Carbonization Furnace
Our furnace utilizes a controlled thermal cycle to ensure the structural integrity of the charcoal while maximizing carbon purity:
Drying Stage (< 160 °C): Initial ignition raises the internal temperature, utilizing external heat to evaporate residual moisture in the raw material.
Initial Stage of Carbonization (160 °C – 280 °C): Thermal decomposition begins. At this point, unstable components like hemicellulose break down, releasing CO_2, CO, and small amounts of organic acids.
Full Carbonization Stage (300 °C – 800 °C): The material undergoes intensive chemical change, resulting in high-density charcoal with significantly increased fixed carbon content.
High-Yield Continuity: The horizontal design allows for massive batch loading, ensuring the continuity of production for industrial-scale operations.
Integrated Syngas Recycling: All combustible gases produced during pyrolysis are returned to the furnace for combustion, achieving zero waste gas pollution and drastically reducing fuel consumption.
Precision Temperature Control: Features a controllable and adjustable carbonization temperature system, allowing operators to fine-tune the process for specific feedstock densities.
Durability & Heat Transfer: The carbonization chamber is constructed from high-heat transfer and high-wear resistance composite materials, ensuring long-term operational stability.
This furnace is the preferred technology for:
Mechanism Charcoal: Transforming sawdust briquettes into high-density, long-burning charcoal logs.
Wood Logs & Branches: Ideal for fruitwood or hardwood carbonization for the premium BBQ market.
Bamboo & Nut Shells: Efficiently processes dense biomass into high-purity charcoal.
Q1: Why choose a horizontal retort over a vertical furnace?
A: Horizontal furnaces are superior for processing sawdust briquettes (mechanism charcoal) and long timber logs because they prevent the material from crushing under its own weight, ensuring the final product remains structurally intact.
Q2: How does the “Close and Extinguish” feature work?
A: Our furnace uses a closed and extinguished coke system that allows for rapid cooling of the charcoal in an oxygen-free environment once the full carbonization stage is complete, preventing accidental combustion and preserving carbon weight.
Q3: Can the furnace run 24/7?
A: Yes. While it operates in large batches, the integrated syngas recycling and heavy-duty composite lining are designed for continuous heating cycles in an industrial environment.
