The working principle of a horizontal carbonization furnace can be understood as a process of thermal decomposition of materials within a closed horizontal tunnel. Its core principle is to create and maintain a high-temperature, oxygen-deficient environment, allowing the material to undergo essential structural reorganization without combustion.
The entire process begins with preheating the furnace. As the material is fed into the furnace at a constant speed, it first undergoes a drying phase to remove surface and internal moisture. As the material is conveyed, the temperature continues to rise, and the material enters the pyrolysis and carbonization phase. During this critical stage, the complex molecular chains of organic matter break down under the high temperature, releasing combustible gases and leaving behind a solid residue rich in carbon.
The horizontal layout of the furnace is key to achieving this continuous operation. It allows the material to move smoothly forward under the influence of gravity, ensuring sufficient and uniform heat exchange with the heat source. This design not only improves thermal efficiency but also makes the entire carbonization process smooth and easy to control, thereby ensuring consistent output.
In short, the working principle of a horizontal carbonization furnace is a system engineering process that integrates heat energy transfer, material transportation, and chemical reactions. Through its ingenious design, it converts unstable biomass into stable biochar, achieving the recycling of energy and resources.
