Log charcoal furnace | horizontal charcoal making machine

The horizontal log charcoal furnace is the carbonization equipment for processing various charcoal. This air-flow type charcoal making machine can not only carbonize wood chips, branches, bamboo, coconut shells, logs, but also biomass briquettes, such as sawdust briquettes. The main structure of the horizontal carbonization furnace includes an outer shell, an inner liner, a pipe, and smoke. Gas purification equipment, etc. Due to its large output and simple operation, this charcoal machine is very popular among charcoal processors.

Horizontal airflow carbonization furnace’s working principle

The log horizontal carbonization furnace can use the combustible gases such as carbon monoxide, methane, hydrogen, etc. generated by the incomplete combustion of biomass raw materials during the carbonization process, and separate impurities such as wood tar and wood acetic acid through a flue gas separation device to obtain pure combustible gas.

These combustible gases will then enter the self-equipped burner of the machine through the induced draft fan for full combustion, heating the cylinder of the horizontal airflow carbonization furnace (the temperature is generally controlled at about 600 ℃). When heated to a certain temperature, it can be fed for carbonization.

When the carbonization raw materials in the charcoal furnace are not fully burned to produce enough combustible gas, the gasifier should be gradually closed, and the flue gas valve of the carbonization host should be opened to realize the self-sufficiency of combustible gas in the carbonization process. Such a carbonization process can recycle combustible gas, save fuel, and reduce environmental pollution.

Main structure of the log charcoal furnace

Although the horizontal log charcoal making machine has a simple structure, 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.

Applications of the airflow charcoal making machine furnace

The horizontal charcoal furnace and other types of carbonization furnaces, such as continuous carbonization furnaces, vertical airlow carbonization furnaces, and spontaneous combustion carbonization furnaces, are important equipment for the production of charcoal. Therefore, charcoal producers and charcoal processing plants should choose their own carbonization machines according to their actual production needs.

Sawdust, dried bamboo, wood chips, branches, log segments, coconut shells, palm shells, straws, jute stalks, peanut shells, distillers grains, etc. can all be used for carbonization. In addition, solid sawdust briquettes processed by the sawdust briquette machine can also be carbonized with this machine. It should be noted that the raw materials processed by the horizontal carbonization furnace should not be too small and light, and the water content should be less than 40%.

The carbonization process of the horizontal charcoal making machine

First, the log sections and branches are neatly placed in the iron frame, and then the iron frame is pushed into the furnace cavity of the carbonization furnace through the conveyor track. If the raw materials are coconut husks and broken branches, they can be directly added to the furnace barrel of the carbonization furnace.

Then, close the cover of the airflow horizontal charcoal furnace, and use mud or insulation cotton to close the gap near the cover. Then, the gasification furnace is used to ignite the fuel in the ignition port at the bottom of the carbonization furnace to fully burn it. Then observe the temperature of the carbonization furnace and whether it produces combustible gas.

When the temperature of the carbonization furnace thermometer reaches about 400°C, the gasification furnace should be shut down and the combustible gas generated in the carbonization furnace is used for cyclic combustion.

Capacity of the log charcoal furnace

The horizontal airflow carbonization furnace manufactured by our factory mainly consists of three models, namely SL-1300, SL-1500, and SL-1900. The output of these three models of horizontal charcoal making machine from 12h to 14h is 900-1200kg respectively , 1500-2000kg, 2500-3000kg. Moreover, the prices of different types of horizontal charcoal furnaces are different, and customers can choose according to their own production needs.
