The continuous carbonization furnace is a new type of charcoal machine equipment. It is used for the mass production of rice husk charcoal and coconut shell charcoal. This industrial charcoal carbonizing furnace kiln is the upgrade of the traditional earth charcoal kiln in many Africa areas. The carbonization furnace can directly carbonize straw chips, rice husks, wood chips, sawdust, coconut shells, palm kernel shells, bamboo scraps, and other biomass materials. With wide applications, it can also carbonize all kinds of wastes, such as paper mill wastes, wood factory wastes, plastic wastes, medical wastes, and municipal solid wastes. This continuous charcoal furnace is often used in various specifications of charcoal briquettes production lines and large-scale charcoal processing plants, such as hookah charcoal production line, barbecue charcoal production line, honeycomb coal production line, etc. Charcoal carbonized by continuous carbonization furnace can be used for industrial metallurgy, chemical, and pharmaceutical, soil improvement, deodorization operations, waste treatment, water purification, and household harmful gas removal.
The main structure of the continuous carbonization furnace
Continuous carbonization furnace is mainly composed of biomass gasifiers, flue gas purifiers, fan, self-matching gas burner, condensing device, etc. In the process of operation, when the continuous carbonization furnace starts to heat up, a heat source is needed to heat the carbonization furnace. One is to use the heat flow generated by the reverberatory furnace to heat the carbonization furnace to achieve the purpose of heating.
How does the commercial charcoal carbonizing kiln work?
The biomass is ignited through the gasifier, and the flue gas generated by the gasifier is recovered and purified, cooled into a combustible gas to burn the carbonization machine. When the carbonization furnace is heated to a certain temperature, the raw materials in the carbonization furnace begin to carbonize, and the flue gas generated by carbonization is purified and cooled to become a combustible gas, which can be used as the carbonization heat source again. Coking furnace after about 30 minutes, charcoal powder from the furnace into the cooling system for cooling, charcoal powder temperature rapidly by around 400 ℃ down to about 20-30 ℃, then charcoal powder can be exported and bagged.

How to make rice husk charcoal with the continuous charcoal machine?
Regular inspection can make coconut shell charcoal carbonization furnace more efficient
Most of the charcoal producers, will not feel strange about continuous carbonization furnace. Because the continuous type carbonization furnace is widely used in charcoal production. Almost all the agricultural and forestry wastes can be carbonized by this charcoal machine, like sawdust, rice husk, coconut shell, peanut shell, straw stems, and so on. Besides, can, tin foil, aluminum foil paper, and other materials can also be carbonized by the continuous carbonization furnace.
Although this coconut shell charcoal carbonizing machine is very practical, if there is no regular shutdown inspection and maintenance in the daily production, the machine’s working efficiency will be reduced and its service life will be affected. Therefore, it is necessary to take an eye on the good maintenance of the carbonization furnace.
How to maintain the continuous carbonizing furnace kiln?
In the charcoal production, according to the need, we sometimes to the charcoal furnace for a short period of downtime inspection and repair. Only regular maintenance and inspection can ensure the efficient operation of the machine and reduce the failure rate. The followings are some instructions for regular inspections of the carbonization furnace.
Short-term downtime check
After the machine is stopped, the whole machine is in a hot state. If the cylinder body is not often rotated, the Central Line of the cylinder body is prone to bending. A rotating cylinder is very important and careful work to ensure that the centerline does not bend. To this end, it is recommended that: In the first half-hour after the stop, turn the cylinder body 1/4 turn every 1-5 minutes; In the first hour after a stop, turn the cylinder body 1/4 turn every 5-10 minutes.
Long-term shutdown and inspection
- After the machine stops, rotate the cylinder body periodically according to the above provisions until it is completely cooled.
- Inspection after shutdown: check all connection bolts for looseness and damage, especially those with the large ring gear. Whether there are cracks in the welds of the cylinder and the backing plate. Whether the lubricating oil at each lubrication point needs to be replaced, cleaned, or supplemented. If it needs to be replaced, the remaining oil should be drained, cleaned, and refilled with new oil.
Lubrication and cooling
Another important work to maintain the continuous carbonizing machine is to give good lubrication to the moving parts of this charcoal machine, so as to extend the service life of the parts and reduce the repair costs.
Pay attention to the following matters when lubricating the charcoal carbonizing machine
- The lubricating oil and grease shall be used correctly. The substitute product must meet the specified grease performance requirements, and only the oil with high viscosity can replace the oil with low viscosity.
- Check the oil level once per shift. If the oil level is lowered to the lower limit of the oil level indicator scale, it must be immediately filled to the upper limit of the oil level indicator.
- After a long-term stop, before starting, the oil must be poured on the roller sliding bearing with the oil pot, and then start.
In addition, it is important to note that the maintenance workers should pay attention to the roller bearings of the cooling system. The surface of the roller is cooled by water flowing from the roller seat. The height of the water surface of the water tank can be controlled by turning the PVC pipe. When the downtime is longer or in winter stops, we should release all the cooling water, so as to avoid freezing caused by pipe expansion crack.
