Do you want your fertilizer to be more competitive? Do you want your fertilizer sales to be better? Then you can  produce charcoal-based fertilizer. Because fertilizers rich in organic carbon are better for stable and high crop yields.If you want to produce charcoal based fertilizer then you need biochar fertilizer machine that can produce carbon. And we recommend the carbonization furnace equipment for you.This article contains the role and working principle of the charcoal furnace equipment in the production line, as well as the advantages of the charcoal furnace equipment. It can provide you with a lot of information you want.

Our three major carbonization furnaces

Continuous Carbonization Furnace

If you want to produce large output of charcoal-based fertilizer, then we recommend you to use continuous charring furnace. Due to their both high operational efficiency with a constant output. And economically viable for large-scale production due to higher throughput. So, these furnaces are ideal for fertilizer industries that produce large volumes of biomass.

Continuous charring furnaces operate uninterrupted, allowing simultaneous addition of biomass and removal of char. Moreover, this is achieved using a conveyor system or moving grate that transports biomass through various heating zones for pyrolysis. In additional, these furnaces are highly efficient and are suitable for large-scale operations that require a constant output of biochar.

Hanging Charring Furnace

If you want a faster time and biomass is more nutritious for biomass production. Then you can choose to use the hanging charcoal furnace equipment. Because it not only provides very even heat distribution, so it can shorten the time of material heating. But also minimizes damage or alteration to the physical structure of the material being processed.

Hanging charring furnaces suspend biomass in a chamber, applying heat from the top, sides, or bottom for even distribution. This furnace type operates in batch mode: material is loaded, processed, and removed before starting a new batch.

horizontal carbonization furnace

If you want a more favorable price approach, then you can consider our horizontal fermenters. It is more affordable and has a smaller footprint.

Horizontal charring furnaces feature a horizontally oriented chamber, where biomass is fed. They operate in both batch and continuous modes, depending on the design. Biomass moves through the chamber on a conveyor belt or by gravity. Heat is applied from the sides, and the chamber sometimes rotates to ensure even carbonization.

What is the structure of the carbonisation furnace equipment?

Carbonisation furnace equipment refers to machinery and apparatus specifically designed for the production of charcoal through the process of carbonization. Carbonization is the process of heating organic materials, such as wood, coconut shells, or agricultural residues, in the absence of oxygen to convert them into charcoal. Charcoal furnace equipment typically consists of the following components:

  • Carbonization Chamber: This is the primary part of the furnace where the carbonization process takes place. In addition, It’s a sealed chamber or retort where organic materials are heated to high temperatures in the absence of oxygen.

  • Heating Source: Charcoal furnaces use various heating sources to raise the temperature inside the carbonization chamber. Moreover,Common heating sources include electricity, gas, or biomass fuels such as wood chips or sawdust.

  • Insulation: To maintain high temperatures and ensure efficient carbonization. And Charcoal furnaces are often insulated with materials like refractory bricks or ceramic fibers. This helps to minimize heat loss and improve energy efficiency.

  • Temperature Control System: A temperature control system is essential for regulating the carbonization process and achieving the desired charcoal quality. It may include thermocouples, temperature sensors, and controllers to monitor and adjust the furnace temperature as needed.

  • Gas Recovery System: During carbonization, gases such as methane, hydrogen, and carbon monoxide are released as byproducts. A gas recovery system collects and channels these gases for reuse as fuel or other purposes, enhancing the overall efficiency of the process and reducing emissions.

  • Condensation and Filtration System: Charcoal furnaces often include systems for condensing and filtering the volatile gases and smoke generated during carbonization. This helps to recover valuable byproducts, such as wood vinegar or tar, while minimizing environmental impact.

  • Loading and Unloading Mechanisms: Charcoal furnace equipment may feature mechanisms for loading organic materials into the carbonization chamber and unloading the finished charcoal after the process is complete. This can include conveyor belts, augers, or manual loading and unloading systems, depending on the scale and design of the furnace.

What is the process of making charcoal from biomass

Step 1: Collection of Biomass

The process starts by collecting biomass materials. Common sources are agricultural residues, forestry waste, and other organic materials. These include rice husks, corn stover, sugarcane bagasse, wood chips, garden waste, and food waste.

Biomass must be dried to reduce its moisture content to around 10-15%. This is crucial because high moisture levels can inhibit the carbonization process. Drying can be done naturally (sun drying) or through mechanical dryers. So we recommend you can use our rotary drum dryer.

The prepared biomass is transported to the carbonizer’s feeding system. This is often done using conveyor belts or augers, ensuring a continuous and controlled flow of material into the carbonization unit.

Inside the carbonizer, the biomass undergoes pyrolysis at temperatures between 300°C and 700°C in a low-oxygen environment. This thermochemical decomposition transforms the organic material into biochar, with by-products such as syngas and bio-oil.

Syngas produced during pyrolysis is captured and cleaned. It can generate heat or electricity to power the carbonization process, boosting energy efficiency. Bio-oil, another by-product, is collected for use in various applications or further processing.

The biochar is discharged from the carbonizer into a cooling system to bring down its temperature and stabilize its structure. This is important to prevent combustion and preserve the quality of the biochar.
