Introduction:

Airflow carbonization furnace

1.airflow furnace process:

1, the drying stage started from ignition to carbonization temperature, slowly rose to 160 ℃, then bar contains moisture mainly rely on external heat and bar produced by the combustion of evaporation. The chemical composition of the bar barely changed.

2, the initial stage of the carbonization stage

depends mainly on the bar itself burned to generate heat, so that the carbonization temperature rise to 160 ~ 280 ℃. At this time, woody material thermal decomposition reaction, which began to change. The unstable component, such as semi cellulose decomposition of CO2, CO and a small amount of acetic acid and other substances.

3, overall carbonization stage

this stage temperature 280 ~ 400 ℃, at this stage, wood materials sharply for thermal decomposition, and generates a large amount of acetic acid, methanol and wood tar and other liquid products. In addition, producing methane, ethylene and other combustible gas, the combustible gas combustion in furnace. The thermal decomposition and combustion gases generated a lot of heat, the furnace temperature is raised. Wooden materials in high temperature dry distillation charring.

If the calcining temperature carbon, in addition to the three stage, but also to the carbonization furnace temperature continues to rise even higher. So, will be able to discharge residual volatile substances in charcoal, increasing carbon content in the charcoal, graphite structure of carbon increased, the conductivity enhancement.

2.air flow type carbide furnace uses and characteristics:

air flow retort is half finished bar under hypoxic conditions dry distillation into important equipment of charcoal, the equipment adopts superconducting heat transfer, reasonable structure, improve efficiency, reduce cost, save the heating energy consumption, while the heating steam cooling system, the cooling speed charcoal, high quality, shorten the production cycle.
