What is the working principle of the charcoal in the charcoal machine?

The carbonization furnace in the charcoal machine uses a self-produced gas furnace as a heat source, uses methane gas through a cyclone, and distributes air into the burner. The outlet temperature of the burner can reach 800 ° C to 1200 ° C, and the flow rate can reach 3 to 5 meters per second. The high-temperature airflow is heated in the periphery of the combustion chamber. It should be noted that when heating, the furnace temperature is between 100 ° C and 150 ° C, which is a greater value of moisture in the furnace. When the raw material rod is put into the kiln, 4 to 8% of water is brought into the furnace. 1700kg of raw materials can bring more than 100 kilograms of water. These waters are the enemy of carbonization. Because the mechanism carbon rods are very afraid of moisture, the water is pulverized into powder, which seriously affects the quality of carbonization. Therefore, the moisture removal system is essential. The key is that the tidal time is 1 to 1.5 hours. When the temperature in the carbonization chamber rises to 300 °C, a large amount of combustible gas is generated in the furnace. Each kilogram of raw material theoretically produces three cubic methane gas, which can be carbonized. Heating, drying heat source, the temperature of the furnace can be adjusted at will, low temperature carbon is generally above 400 ° C (8 hours can be completed), high temperature carbon is above 600 ° C (10 hours to complete)
