2013! Air flow type carbonization furnace

Use and features of air flow type carbonization furnace:

1. Air flow type carbonization furnaceis to pay great semi-finished products under hypoxic conditions dry distillation into charcoal important equipment.
2. Air flow type carbonization furnaceusessuperconductingheat transfer,reasonablestructure,improveefficiency,reducecosts,saveheatingenergyconsumption.
3. Air flow type carbonization furnacealso usesheatingsteamcoolingsystem,high Coolingspeedandhighqualityofcharcoal,greatlyshortentheproductioncycle.

Working principle of air flow type carbonization furnace:

l Air flowtypecarbonizationfurnacewill bepaidsemi-finished products or the branches of bamboo, wood materials in hypoxic conditions, such as combustion ( or surface mesh Burn ) and decomposition of generating combustible gas, Tar and black - charcoal.

l BambooandWoodMaterials(includingsalary bar)incarbonizationfurnaceprocessesare as follows:

1. Comprehensive carbonized stage

l This phase of the temperature is 280-400°C, in this stage, the woodiness material sharply on thermal decomposition, and at the same time generate a large amount of acetic acid, methanol and wood tar, etc liquid product. In addition also produced methane, ethylene, and other combustible gas, the combustible gas in the furnace combustion. Thermal decomposition and gas combustion produces a large amount of heat, make the furnace temperature rise. Woodiness material under high temperature carbonization into carbon.
