Wie man Schritt für Schritt Holzkohle mit dem Luftstrom-Hebeverfahren herstellt?

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.

Die Details des Prozesses zur Herstellung von Holzkohle durch die Luftstrom-Aufzieh-Ofen zur Verkohlung:

Stufe 1: Trocknungsprozess

After placing the inner stove which is of the biomass rods in the Holzkohle 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.

Stufe 2: Pyrolyseprozess

Wenn die Temperatur im Verkohlungsofen 170 °C – 200 °C erreicht, wird mit einem Simmer die Ofentemperatur auf etwa 340 °C erhitzt. Die zweite Phase dauert etwa 2 Stunden und 30 Minuten.

Stufe 3: schnelles Pyrolyseverfahren

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.

Stufe 4: das Ende der Verkohlung

Wenn die Temperatur im Ofen etwa 400 °C erreicht hat, ändert sich danach nichts Wesentliches mehr. Mit einem kleinen Feuer wird weiter erhitzt, wenn die Rauchabgabe am Rauchabzug deutlich reduziert und leichter wird, wird die Flamme gelöscht und die Verkohlung ist beendet. Die vierte Phase dauert etwa 40 Minuten.

Stufe 5: Abkühlung und Entladung des Holzes

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 Holzkohlebriketts 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 Luftstrom-Aufzieh-Ofen zur Verkohlung, 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.
