How to make charcoal without smoke?

To make smokeless charcoal, it is necessary to select raw materials, crush and dry them, then use pyrolysis gas to cycle and carbonize them into smokeless charcoal blocks in an oxygen-free environment at low temperature, and then cool, screen and package them into commercial smokeless charcoal. The whole process is environmentally friendly and pollution-free. Next, we will introduce the process of producing smokeless charcoal in detail:

1. Pre-treat the raw materials of smokeless charcoal:

Crushed and dried raw material for smokeless charcoal

a. Select the right raw materials: Selecting the right raw materials is the key to making smokeless charcoal. Select raw materials with low water content, low ash content and low sulfur content, such as sawdust, straw, corn cobs, peanut shells, etc. These raw materials can make better quality smokeless carbon. Mix the raw materials in a certain proportion to form a uniform mixture. The mixing ratio can be adjusted according to needs.

b. Crush the selected raw materail: Then crush them through the Henan DOING double-shaft into particles below 30mm to ensure the carbonization effect of smokeless charcoal, improving the quality stability of smokeless charcoal.

c. Drying raw materials: The Henan DOING automatic conveyor belt transports the crushed raw materials to the carbonization furnace, and uses a hot air drying system to dry them so that the raw material humidity reaches 8%-12%. The drying time is about 30 minutes, the temperature is 200-400 degrees.

2. Carbonization process of smokeless charcoal:

a. Low temperature carbonization: Carbonization temperature is one of the important factors affecting the quality of smokeless charcoal. The carbonization time is about 30 minutes, the carbonization temperature is 400-600 degrees. Low temperature carbonization allows the volatile matter in the raw materials to slowly precipitate and fully react, thereby obtaining high-quality smokeless charcoal.

b. Precise oxygen-free or micro-oxygen environment: Henan DOING uses an oxygen-free carbonization furnace to make smokeless charcoal, accurately controls the oxygen content in the carbonization furnace, and turns the raw materials into smokeless charcoal in an oxygen-free or micro-oxygen environment, reducing the smoke caused by incomplete combustion and the emission of non-polluting gases during the production process.

c. Recycling of pyrolysis gas: In the process of making smokeless charcoal, Henan DOING is equipped with a gas circulation and purification system to optimize the airflow channel in the carbonization furnace, so that the hot air flow is evenly distributed in the carbonization furnace, and the pyrolysis gas generated during the carbonization process is collected and reintroduced into the carbonization furnace as fuel after purification to provide heat for the carbonization process, so that the combustible components in the pyrolysis gas are fully burned, and the smoke emission in the production process of smokeless charcoal is reduced.

3. Post-processing of smokeless charcoal

a. Heat dissipation and cooling: After carbonization is completed, the smokeless charcoal is naturally cooled or forced to cool in an oxygen-free environment to avoid spontaneous combustion of the charcoal blocks. The time is generally 16 hours.

b. Pressing of carbon blocks: If there are other requirements for the shape of the finished smokeless charcoal, the carbon blocks can be further pressed into shapes such as round, square, etc.

c. Packaging: Selected smokeless charcoal need to be packaged. The packaging of smokeless charcoal should use fire-resistant materials, such as sealed plastic bags or fire-resistant paper, and fix the packaging shape to avoid cracking or deformation.
