Come fare il carbone con il forno di carbonizzazione a sollevamento dell'aria passo dopo passo?

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.

I dettagli del processo per la produzione di carbone di legna da parte del fornace di carbonizzazione a sollevamento dozzina d'aria:

Fase 1: processo di essiccazione

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

Fase 2: processo di pirolisi

Quando la temperatura nel forno di carbonizzazione raggiunge 170 °C – 200 °C, usare un sobbollire per riscaldare la temperatura del forno a circa 340 °C. La seconda fase dura circa 2 ore e 30 minuti.

Fase 3: processo di pirolisi rapida

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.

Fase 4: fine del carbonizzazione

Quando la temperatura nel forno ha raggiunto circa 400 °C, non si verifica alcun cambiamento di temperatura significativo successivamente. Usa un fuoco piccolo per riscaldare, quando il fumo dall'uscita del fumo è significativamente ridotto e alleggerito, la fiamma si spegne e la carbonizzazione è terminata. La quarta fase dura circa 40 minuti.

Fase 5: processo di raffreddamento e scarico del carbone

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 mattonelle di carbone 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 fornace di carbonizzazione a sollevamento dozzina d'aria, 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.
