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.
