Horizontal carbonization furnace is a new type of charcoal making equipment. It adopts a horizontal design to reduce machine height. So it is more convenient for loading raw materials. Same as other airflow carbonization furnaces, it also includes a smoke recycle system. And smoke generated in the carbonizing process enters the purifier and then you can ignite it for heating the furnace. For this, it is very popular among charcoal processors.
What is the working principle of horizontal carbonization machine?
3 Main structures of horizontal wood charcoal making machine
The horizontal charcoal making machine has a simple structure, including the three most important parts: thermal insulation rock wool, flue gas circulation pipe and trolley.
What other designs in horizontal carbonization furnace?
Besides the above introduction, its manufacturing process is very sophisticated and contains many components. Such as the gasification system, flue gas purification system, carbonization system, control system, combustion system, and power system.
3 Temperature ranges in the carbonization process of horizontal carbonization machine
There are 3 temperature ranges when you use horizontal carbonization equipment. The following are the detailed information:
From the start of ignition, the furnace temperature rises to 160°C. At this time, the moisture contained in the machine-made rod mainly relies on external heating and the heat generated by its own combustion to evaporate. The chemical composition of the machine-made stick remains almost unchanged.
This stage mainly relies on the combustion of the rod itself to generate heat, causing the furnace temperature to rise to between 160 and 280°C. At this time, the wood material undergoes a thermal decomposition reaction and its composition begins to change. Among them, unstable components, such as hemicellulose, decompose to produce CO2, CO and a small amount of acetic acid and other substances.
The temperature at this stage is 300~650℃. During this stage, the wood material undergoes rapid thermal decomposition. At the same time, a large amount of liquid products such as acetic acid, methanol and wood tar are produced. In addition, producing flammable gases such as methane and ethylene. And these flammable gases are burned in the furnace. Thermal decomposition and gas combustion generate a large amount of heat, which increases the temperature of the furnace and makes the wood material carbonization into charcoal at high temperature.
Why do so many manufacturers choose horizontal carbonization furnace?
By summarizing the past data of selling, we can find that this horizontal carbonization furnace is popular with charcoal suppliers. Why? Because it has many advantages which can attract biochar manufacturers to invest in as follows:
