Raw materials of biochar charcoal wood retort kiln

 

1) Tree branches whose diameter is more than 30mm.

2) Some nut shells, such coconut shell, walnut shell, etc.

3) Biomass briquettes made  from sawdust, small agriculture wastes.

 

Working principle of  biochar charcoal wood retort kiln

 

1) Drying stage: First, we should set fire on wood, tree branches, wood briquettes, etc.(which we have laid

 

in the carbonization furnace) through four holes which locate furnace's bottom. Then close the holes. And 

 

close the upper holes till the thermometer (which loactes on the surface of thr furnace) reaches 100°C. At this stage, the temperature in the furnace will reach about 100-160°C,and all the water content will be evaporated.(carbonization furnace)

 

2) Initial phase of carbonization: At this stage, the temperature in the furnace will reach 160-280°C, wood,tree branches, wood briquettes etc. will be decomposed into carbon dioxide, carbon monoxide, etc.(carbonization furnace)

 

 

3) Carbonization stage: At this stage, the temperature will reach 280-450°C, wood, tree branches, woodbriquettes,etc. will be decomposed rapidly and finally carbonized into charcoal.(carbonization furnace)

 

 

4) Carbonization time: 34 hours (Carbonize briquette in furnace about 14 hours,then cool them about 20 hours in carbonization furnace)
