The continuous carbonization furnace is an energy-saving carbonization equipment designed for large-scale biomass charcoal production. It has 24 hours of uninterrupted operation capacity, can realize constant feeding and discharging, and the output can reach 800-1000kg/h.
The equipment generates high-quality charcoal products by carbonizing wood chips, peanut shells, rice husks, straw, and other biomass materials at high temperatures. The combustible gases (e.g., carbon monoxide, methane, hydrogen) generated during the carbonization process can be heated by cyclic combustion. This greatly reduces energy consumption and cuts down on environmental pollution, making it an ideal choice for modern, environmentally friendly charcoal production processes.
Raw materials of charcoal carbonization furnace
The continuous charcoal furnace is suitable for a wide range of biomass feedstocks with a carbonaceous structure, including but not limited to:
- Wood chips, sawdust, tree branches, wood chunks, tree barks.
- Agricultural waste: peanut shells, rice husks, corn stalks, hemp stalks, cotton stalks.
- Shell materials: coconut shells, walnut shells, palm shells.
- Other organic wastes: herbal residues, fruit and vegetable wastes, plant fibers, etc.
Diversified raw material adaptability allows users to choose flexibly according to local resources, effectively improving the utilization rate of raw materials.
Finished products characteristics and application prospect
After continuous carbonization, the biomass charcoal shows black color, high density, high calorific value, stable combustion, no smoke and less ash, and is widely used in the following fields:
- Energy supply: replacing traditional coal, used for home heating, barbecue charcoal, industrial boiler fuel.
- Agricultural use: soil conditioner, biochar fertilizer, enhance soil fertility and water retention.
- Industrial use: used in metallurgical desulfurization, activated carbon processing and other deep-processing fields.
- Environmental use: as an adsorbent to treat wastewater and waste gas, reduce carbon emissions.
Different application scenarios have different requirements for charcoal products, and customers can carry out follow-up treatment or deep processing of the finished products according to their needs.
Structure of rotary charcoal carbonzation furnace
Continuous carbonization furnace as a set of integrated, intelligent and efficient carbonization equipment. It mainly consists of the following core parts, and each module operates synergistically to guarantee the efficient and energy-saving operation of the equipment:
- Gasifier: used for initial preheating of the equipment, which can be turned off later to save energy.
- Gasifier: for initial preheating of the equipment, which can be turned off at a later stage to save energy. Carbonizer body: adopting rotary design to realize continuous and uniform carbonization.
- Screw conveyor: continuous feeding to ensure uninterrupted charring process.
- Flue gas purification system: recycle and purify the combustible gas to realize circulating heating.
- Induced draft system: send the purified gas into the combustion chamber for continuous heating.
- Cooling discharging device: quickly cool down the charcoal products for easy storage.
- Storage bin: collect the cooled charcoal for subsequent use.
Continuous carbonization furnace working principle
The carbonization process of materials in the continuous carbonization furnace is mainly divided into the drying stage, the initial stage of carbonization, the full carbonization stage, and the cooling stage.
Etapa de secado
- Heated by gasifier ignition, the furnace temperature rises.
- Moisture in the material begins to evaporate, relying on an external heat source.
- No significant chemical reaction has occurred in the material at this stage.
Initial carbonization stage
- The material begins to decompose slowly and releases a small amount of heat energy.
- The temperature required for carbonization is gradually reached and the internal chemical structure begins to change.
- Some of the unstable components begin to decompose.
Complete carbonization stage
- Rapid pyrolysis of the material produces a large amount of liquid by-products such as wood tar, acetic acid and methanol.
- At the same time, combustible gases such as methane and ethylene are released.
- These gases are burned in the furnace to generate high heat, which further promotes carbonization and eventually produces charcoal.
Cooling stage
- The material after carbonization is completed needs to be cooled naturally or forcibly.
- After cooling, it can be stored safely to avoid spontaneous combustion in contact with air.
Advantage of the continuous carbonization furnace
- Continuous operation, high degree of automation: it can realize 24-hour uninterrupted operation, greatly improving production efficiency and saving labor costs.
- Superior environmental performance: equipped with flue gas recovery, combustion and dust removal devices to ensure that the exhaust emissions meet the standards, environmental protection and no pollution.
- High-efficiency cooling system: spiral water cooling + coil cooling design, rapid cooling, safe and efficient, while saving space.
- Intelligent feeding system: the whole set of equipment is equipped with bucket elevator to realize automatic feeding, saving time and labor.
- Excellent carbonization effect: for sawdust and other fine particles of raw materials, it is not easy to pile up the problem of incomplete carbonization, the rotary furnace structure can achieve full and uniform carbonization.
- Uniform heating, rapid heat transfer: the rotating structure of the furnace body makes the materials receive heat evenly and the carbonization is more thorough. The processing capacity is as high as 3-5 tons per hour, and the efficiency is 10-20 times of the traditional static carbonization furnace.
