Comment fabriquer du charbon de bois avec le four à carbonisation par soufflage d'air étape par étape ?

The airflow hoisting carbonization furnace is composed of the movable outer stove, inner stove, airflow pipes, ignition port, hoisting equipment, and the flue gas purification equipment. The inner stove is independent so that the charcoal furnace can be a single inner stove, three inner stoves, and four inner stoves. The carbonization inner stoves are connected by pipes, and the combustible gas in the carbonization process can burn each inner furnace which has high working efficiency and can save fuel consumption.

Les détails du processus de fabrication du charbon de bois par le four de carbonisation à levage d'air:

Étape 1 : processus de séchage

After placing the inner stove which is of the biomass rods in the charbon furnace, to ignite at the ignition port below the furnace, and the temperature in the furnace is gradually heated from normal temperature to about 100 °C. Because the temperature inside the furnace before ignition is low, this process should be heated with a large fire, reaching 100 degrees to the left, and then use a small fire to heat the carbonization temperature to 170 ° C – 200 ° C or so.

Étape 2 : processus de pyrolyse

Lorsque la température dans le four de carbonisation atteint 170 °C – 200 °C, utilisez un mijoteur pour chauffer la température du four à environ 340 °C. La deuxième phase dure environ 2 heures et 30 minutes.

Étape 3 : processus de pyrolyse rapide

When the temperature in the furnace reaches about 340 °C, use a small fire to heat the furnace temperature from 340 °C to 380 °C – 400 °C. The third phase takes about 2 hours.

Étape 4 : fin de la carbonisation

Lorsque la température dans le four atteint environ 400 °C, il n'y a plus de changement de température significatif par la suite. Utilisez un petit feu pour chauffer, lorsque la fumée sortant du conduit de fumée est considérablement réduite et éclaircie, éteignez la flamme et la carbonisation est terminée. La quatrième phase dure environ 40 minutes.

Étape 5 : refroidissement et déchargement du charbon de bois

After the carbonization is completed, if no other cooling measures are taken, the fire can be sealed and the charcoal can be naturally cooled. There are two ways to seal fires: Method 1: seal the smoke outlet and cool the charcoal, and the surface of the Briquettes de charbon is good. This method takes about 16 hours to cool down the charcoal. Method 2: completely open the smoke outlet and cool the charcoal. This process is the same as method 1, but the charcoal surface is not shiny like the former. This method takes about 16 hours for cooling. In these two ways, when the temperature in the furnace drops to about 40°C, to discharge the charcoal is ideal.

Note: If there is no temperature measuring device or temperature measuring device damaged in the four de carbonisation à levage d'air, the small-fire firing in the carbonization process shall take 7-8 hours. It is strictly forbidden to use a large fire during the carbonization process. At the end of carbonization, when the amount of smoke from the outlet is significantly reduced and the smoke is light, the flame should be extinguished and the carbonization is over.
