Products Description
The smokeless continuous carbonization furnace consists of a conveyor, a high-temperature furnace, dust removal, decoking, purification, a gas cabinet, a power distribution cabinet and other equipment. It is the latest developed continuous carbonization equipment that is efficient, environmentally friendly and intelligent.
This equipment is the latest carbonization equipment in China that integrates the co-production of "carbon, gas, oil and
fertilizer". It can carbonize a variety of materials, such as straw, branches, wood chips, fungus materials, etc. It has no strict requirements on the materials and can be directly carbonized without crushing. It also realizes production processes such as continuous feeding, continuous carbonization, layered carbonization, intelligent control, automatic collection of tar and combustible gas, thereby improving the quality of carbon powder, solving the various drawbacks of traditional carbonization production such as low efficiency and high labor intensity, and truly realizing the efficient and rational utilization of renewable resources.

Technical Parameters
The carbonization process in a Biochar kiln can generally be divided into the following three temperature stages:
Drying Stage: From ignition to the furnace temperature reaching 160°C, the moisture content in the briquettes relies mainly on external heating and heat generated from their own combustion for evaporation. The chemical composition of the briquettes remains largely unchanged during this stage.
Initial Carbonization Stage: This stage is driven primarily by the combustion of the briquettes themselves, raising the furnace temperature to between 160°C and 280°C. At this point, thermal decomposition reactions occur in the woody material, leading to changes in its composition. Unstable components such as hemicellulose undergo decomposition, producing substances like CO2, CO, and small amounts of acetic acid.
Full Carbonization Stage: This stage occurs within the temperature range of 300°C to 650°C.During this stage, the woody material undergoes rapid thermal decomposition, simultaneously generating significant amounts of liquid products such as acetic acid, methanol, and wood tar. Additionally, combustible gases like methane and ethylene are produced. These gases can be controlled and utilized through valves for cyclic combustion. The combined processes of thermal decomposition and gas combustion generate a substantial amount of heat, raising the furnace temperature. The woody material is distilled into charcoal under high temperatures.
For the production of high-temperature charcoal, apart from the three stages mentioned above, additional heat is applied to raise the furnace temperature further to around 800°C to 1000°C. This helps to expel volatile substances remaining in the charcoal, increase the carbon content, enhance the graphite structure within the charcoal, and improve its conductivity.
