What is a carbonization furnace?

The carbonization furnace(charcoal kiln, charcoal furnace) is a kind of equipment used to convert organic raw materials (such as wood, bamboo, etc.) into charcoal. During the carbonization process, the organic raw materials are heated at high temperatures without burning, decomposing solid charcoal and gas products.

This equipment is usually used to produce charcoal products such as wood charcoal, bamboo charcoal, etc. It is characterized by high efficiency and energy saving, and is widely used in agriculture, industry and energy fields.

Unique carbonization furnace design

  • The unique design of the Continuous Carbonization Furnace lies in its highly efficient continuous heating system, which is able to continuously provide a stable high-temperature environment to ensure full carbonization of the raw materials.
  • In addition, the interior of the furnace adopts a patented design of the trough structure, which enables the raw materials to be heated evenly and maintains good airflow circulation, improving carbonization efficiency.
  • Meanwhile, the carbonized boiler is also equipped with an intelligent control system, which can automatically monitor the temperature and operation status to ensure safe and stable operation.
  • The overall design is compact, covers a small area, easy to install and maintain, and is suitable for the carbonization production of various raw materials.

How does the coal furnace work?

A continuous carbonization furnace is a device used to produce coal, which works by subjecting coal or other organic materials to high temperatures so that they undergo a pyrolytic reaction to produce coal. The process of continuous carbonization can be described:

  1. Inside the furnace, the burning material (usually wood or gas) provides heat, which raises the temperature inside the furnace.
  2. Subsequently, raw materials (e.g., wood sawdust, wood chips, plant straw, etc.) are placed into the furnace and undergo a carbonization process in a high-temperature environment, ultimately converting them into coal.
  3. At the same time, the gases inside the furnace are released and processed for use as fuel or other purposes.

The entire process requires control of parameters such as temperature, ventilation and heating rate to ensure that a compliant coal product is produced.

Working principle of continuous carbonization furnace

Here describe the whole carbonization process, and the carbonizing process lasts 15-20 min. The details are as below:

Ignition

First, the biomass material is ignited in the gasifier, because the continuous charcoal carbonization machine needs to be warmed up, which takes about 1 hour. The whole process only needs to be ignited once.

Preheating stage

The preheating is completed when the preheating temperature reaches 280°-330° and the raw material is put in.
When the raw material is coconut shell, the furnace temperature is 330° to put in the raw material; when the raw material is palm shell and lighter raw material such as rice husk and wood chips, the furnace temperature reaches 280° to put in the raw material.

Ignite the combustion chamber

After 10-20 minutes of carbonization, when hot gas is observed to be generated in the burning pool, ignite the gas to make the combustion chamber burn.
Turn off the fire head and do not use it again because the combustible gas that is generated by the carbonation process of flue gas by spraying, cooling and purification process can burn secondary.

Carbonization process

Continuous carbonization can then take place. Each round of carbonization takes 20 minutes.

Discharge and cooling

The discharge has a cooling process, which is carried out through a condensation tube, with a double-layer structure. The interior contains the carbonized feedstock and the exterior is cooled by water.
