smokeless wood charcoal carbonization tunnel furnace for charcoal

Introduction of tunnel furnace for charcoal carbonization : Carbonization stove can carbonize different biomass materials into good quality charcoals, just like wood, bamboo, sawdust, rice husk, straw and stalk, coconut shell, peanut shell, olive wastes, sugarcane, ect.

 tunnel furnace for charcoal carbonization  Structure:

♦   Ourter furnace

♦   Inner stove

♦   Cover

♦   Hoist

♦   Purify system

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 80-120minutes for this process to reduce water vapor from your materials.

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

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 is good. When the temperature lowers than 50 degree, you can take charcoal out. Otherwise, the charcoal will burn again when met oxygen of air.

Q1: What is the usage for the clean system?

A1: In the carbonizing process, first come out is steam with bad smell. The clean system inside with floating cold water,

when the hot steam meet the cold pipe, the steam will turn to water, thus the steam and bad smell will reduce much.

Q2: What is the most suitable temperature for carbonizing?

A2: The temperature should be 420-480 °C

Q3: What is the power for the electric hoist? 

A3: In general, its power is 0.5kw, three phrase, 380V, 50Hz. If your voltage is different with ours, our technician

can custom made the motor for you.
