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.

Maelezo ya mchakato wa kutengeneza makaa ya mawe kwa njia ya luftflödeslyft karboniseringsugn:

Hatua ya 1: mchakato wa kukausha

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

Hatua ya 2: mchakato wa pyrolysis

Wakati joto kwenye tanuru ya kuoka makaa ya mawe linapofikia 170 ° C – 200 ° C, tumia moto mdogo kupasha joto tanuru hadi takriban 340 ° C. Awamu ya pili inachukua takriban masaa 2 na nusu.

Hatua ya 3: mchakato wa pyrolysis wa haraka

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.

Hatua ya 4: mwisho wa ukaa

Wakati joto kwenye tanuru lilipofikia takriban 400 ° C, hakukuwa na mabadiliko makubwa ya joto baadae. Tumia moto mdogo ili kupasha joto, wakati utoaji wa moshi kutoka kwenye mlangoni wa moshi unapungua sana na kuwa nyepesi, moto unazimwa na mchakato wa kuoka umekamilika. Awamu ya nne inachukua takriban dakika 40.

Hatua ya 5: Mchakato wa kupooza makaa ya mawe na kuachilia

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 za makaa 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 luftflödeslyft karboniseringsugn, 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.
