How To Use A Charcoal Kiln?

Charcoal is made by heating wood to high temperatures in an oxygen-deficient environment. Charcoal is a versatile fuel. It plays a vital role in various energy sectors. With the growing demand for the energy sector. The use of charcoal kilns to produce charcoal is essential.

 

Introduction of Charcoal Kiln: 

Charcoal Kiln is specialised in the carbonisation of raw materials such as wood, fruit shells, coconut shells, logs, fruitwood, and so on. It adopts an endothermic design. Through high temperature flue gas circulation to achieve full combustion and carbonisation of raw materials. Suitable for small and medium-sized charcoal making factories. It has the advantages of convenient operation, high production efficiency, and good carbonisation effect.
   

Charcoal Kiln Working Principle 

adopts the principle of dry distillation carbonisation. The reaction process of heating and decomposition under the condition of air isolation. Gas, vapour, and solid charcoal are produced in the process of dry distillation and carbonisation of wood. The combustible gas is sent to the bottom of the charcoal kiln through the rotary pipe for self-heating. Wood tar, wood acetic acid, etc., are obtained during the carbonisation process and can be collected. The flue gas produced by carbonisation can be recycled. Thus, charcoal is made.
The charcoal kiln can send raw materials such as wood, rice husk, sticks, fruit wood, bamboo tubes, and so on to the kiln body. The raw materials are then heated through the ignition port to ignite the charred raw materials inside the furnace. The smoke is produced during the process. Through the flue gas purification system for filtration and dust removal, etc.. The combustible flue gas is transferred into the fire channel at the bottom of the charring furnace for combustion. Thus, the purpose of secondary heating is achieved. The raw material in the furnace body reaches the desired thickness of the question in the kiln body curtain combustion for cracking carbonisation into charcoal.

 

Charcoal Kiln Burning To Charcoal: The Correct Way To Use: 

Load wood: Load raw materials; the more dense the load, the better. If the diameter of the wood is more than 30cm, it is recommended to crush it first. If it is freshly cut wood with a large moisture content, it needs to be dried and then carbonised.
Charcoal kiln preheating: the heat source is first ignited and heated to 200℃ in the early stage. This step is used for the bottom of the wood furnace body ignition heating. Avoid generating smoke.
Gas decomposition: when the temperature inside the furnace body reaches 200℃. Wood is the pyrolysis decomposition of combustible dry distillation gas. Pipes lead to the bottom of the furnace body to start combustion. At this time, there is no need to put fuel. It can make its own decomposition gas combustion heating; this process is smoke-free and odourless.
Carbonisation and cracking: when the gas combustion is heated to 400-500℃. The temperature control valve behind the charcoal kiln is used to control the temperature stability range. Until the combustible gas combustion is completed. Charcoal decomposition is completed. Switch off the fire and allow the charcoal kiln to cool naturally. The cooling process may take several days. The charcoal kiln is switched on, and the charcoal is removed when the temperature reaches 50°C.
Screening package: The charcoal is screened to produce product charcoal. It is then packaged and stored.


There are many types of charcoal kilns, which can be customised and designed according to the actual production needs of different customers. The capacity and price of different configurations of charcoal kilns vary. Choosing the right charcoal kiln also takes into account the raw material of wood, capacity requirements, and quality of the finished charcoal. If you want to buy a charcoal kiln. Your enquiry is welcome.
