The carbonization machine uses the fuel rods in the furnace-semi-finished products. After ignition, the heat generated by the surface oxidation and combustion causes the fuel rods to decompose and carbonize. During the decomposition process, combustible gas, tar and char are generated. Among them, the combustible gas is mixed with a small amount of oxygen entering the furnace, and then an oxidation reaction occurs to generate more heat, which further maintains the temperature in the furnace and meets the heat required for the decomposition of the fuel rod.

The carbonization machine does not require any additional heating equipment. The heat required for the carbonization of the fuel rods in the carbonization furnace comes from the spontaneous combustion of the fuel rods themselves and the oxidation of combustible gases in the furnace. Electricity, gas, coal and firewood are not required for heating, so no additional heating equipment is required.

The carbonization machine has mature technology, simple operation, easy to master, safe and reliable. The spontaneous combustion type carbonization furnace has a history of more than ten years, and the operation technology is mature. After the carbonization furnace is ignited, the temperature change rate of the furnace can be changed only by adjusting the air intake to meet the different requirements for carbon quality. Therefore, it is possible to burn medium and low temperature carbon and high temperature carbon. In the process of operation, you only need to master the skills of ignition, adjusting the air intake and closing the fire. In addition, the carbonization furnace is connected to the outside world through a large-caliber chimney, and there will never be a safety hazard of excessive pressure due to blockage of the pipeline. The charring rate of spontaneous combustion fuel rods is high, up to more than 40%. The carbonization furnace has a long life and low maintenance costs.
