The carbonization process is the core of the production technology of machine-made charcoal

The carbonization process is the core of the production technology of machine-made charcoal. Just like building a building, a good raw material is that the foundation of the building is the underground part. The carbonization technology used in the carbonization process is the aboveground part of the building. Carbonization is divided into three stages: low temperature, exhaust temperature, high temperature calcination, and cooling. The carbonization furnace must be tightly sealed. If there is any air leakage, the amount of oxygen entering the carbonization furnace (or kiln) cannot be controlled. The fuel rod in the furnace is prone to excessive spontaneous combustion, causing the carbonization temperature to rise too quickly, resulting in loose and weak density of the charcoal produced, which is prone to fragmentation. Moreover, excessive oxygen can cause some fuel rods to burn into white powder (ash), resulting in a decrease in carbon production and an increase in the cost of finished carbon. When the furnace temperature rises to 300 degrees, a large amount of combustible gas can be generated inside the furnace. Each kilogram of raw materials can reasonably produce three cubic meters of methane gas. These gases can be used to heat up the furnace. Discharging a heat source that can be used for drying at a temperature of over 400 degrees Celsius is necessary for the insulation and calcination stage. Sealed oxygen free closed fire can be used for self ignition cooling or water cooling cooling. After the charcoal is discharged from the kiln, it should be ventilated first and then discharged to prevent carbon dioxide poisoning. The charcoal from the kiln should be stored outdoors for at least 8 hours. Prevent the resurgence of ashes and the occurrence of fires.
