Request for Quotation- Supply of Carbonization Furnace
Overview :

Product background

The carbonization Furnace comprises of three inner stoves: when one inner stove gets finished, it can be hoisted outside. When the first inner stove is cooling, the other inner stove can be carbonized at the same time, in this way the cooling time is significantly reduced. thus, the productive efficiency significantly increases as well.

The stove adopts the structure of unique air storage chamber, to fully reuse the smoke produced during the process of carbonization. The redundant smoke can be used in drying and carbonizing, saving much fuel during the whole process, and increasing the enterprise revenue.

 

Working Process

1. Heat

After sealing work, use wooden wastes or gas to heat furnace. Primarily, 10 minutes big fire to burn, when the temperature reaches 90 degrees centigrade, turn to use slow fire to heat. It takes 80 to 120 minutes for this process to reduce water vapor from your materials.

 

2. Pyrolyse

Keep heating, when the temperature reaches 180-235 degrees centigrade for 3-5 hours, it will produce gas from this process. Reuse this gas as fuel to heat. The whole process is about 8hours. When the temperature reaches the highest level and it reduces, the dry distillation process will complete.

 

3. Cooling

Hang the Inner pot outside and seal the pipes of cover. Let it cool naturally. Cooling time is longer, the quality of charcoal should be good. When the temperature gets lower than 50 degrees, you can take charcoal out. Otherwise, the charcoal will burn again when in contact with oxygen in the air.
