Working process of woo oven charcoal carbonizing furnace :
1.Drying stage begins from the ignition for airflow coconut shell
charcoal carbonizing furnace
After the temperature of furnace rise to 160 ℃ slowly , the water
contained in the pay great begin to evaporate rely on the heat,
from plus heat and itself great heat produced by
combustion.Chemical composition of pay great almost unchanged.
2.Initial phase of carbonization charcoal carbonizing furnace :
This stage mainly depend on the heat from own burning, make
charcoal carbonizing furnace temperature rise to 160 ~ 280 ℃.At
this point, the woodiness material come about thermal decomposition
reaction, and its composition have started to change.The material
of instability, such as the production of hemicellulose decompose
substances CO2, CO, and a small amount of acetic acid.
3. Comprehensive coking stage for charcoal carbonizing furnace :
This stage, the temperature is 280 ~ 400 ℃, in this phase, the
woodiness material rapidly to carry on the thermal decomposition,
and generate a large amount of acetic acid, methanol and wood tar
and other liquid products.In addition, produce the combustible
gases methane, ethylene, the combustible gas to burn in the
oven.Thermal decomposition and gas combustion produces a large
amount of heat, make the temperature to rise.Woodiness material at
high temperature carbonization into charcoal.
To calcine temperature carbon, in addition to the above three
stages, but also make the coking in furnace temperature continues
to rise even higher.So, can discharge residual volatile substances
in charcoal, improve carbon content in charcoal, make carbon
graphite structure increase, enhanced electrical conductivity.
