Carbonization is a very important process for making charcoal briquettes. The whole charcoal carbonizing process can be divided into the following three stages
1. Briquettes Drying Stage
From the ignition until the temperature reach 160?, the biomass sticks moisture evaporates steadily mainly depends on the heating resource and independent burning value. There is no chemical changes in this stage.
2. Initial Carbonization Stage
This process mainly depends on the briquettes burning to produce heat and makes the temperature rise to 160?280?. The biomass briquettes start to have thermal deposition. For example, the hemicellulose decompose into CO2, CO and amount of acetic acid.
3. Comprehensive Carbonizing Stage(temperature 300?650?)
In this stage, the biomass material undertake chemical decomposition radically. It produces much acetic acid, carbinol and woo tar as well as combustible gas including methane and ethylene. These gas contributes to making a high temperature and the biomass briquettes are distilled into charcoal.
If you want to make pyrocarbon, the furnace temperature should reach 800??1000?.
Azeus Provide Three Types of Carbonization Furnaces
? Self-ignition Carbonization Furnace Features
This type charcoal carbonizing stove adopts self-ignition principle to decompose the briquettes into combustible gas, wood tar and charcoal. It can be applied to carbonize wood, logs, biomass briquettes, fruit shell and bamboo, etc. This charcoal carbonization machine is featured with easy operation, high efficiency, no smoke, etc. Made of mobile steel plates, this machine has large effective volume and long service time.
? Airflow Carbonization Stove Features
? Adopting advanced thermal current technology, this machine can greatly improve carbonizing rate from 80% to 99% .
? The furnace effective volume is 3m³, 5m³, 6m³, 8m³, every model can be customized.
? Carbonizing rate is more than 40-60%, yield of finished products is more than 95%.
