Rotary kiln how to make biochar from sawdust wood bits agricultural wastes

Structure of Rotary Kiln:

♦ Feeding system

♦ Gasification furnace

♦ Carbonization furnace

♦ Output device

♦ Smoke purify system

♦ Cooling system

♦ Electric cabinet

 

Features of Rotary kiln:

--- Continuous working, higher capacity, one side feeding raw material, and one side get biomass charcoal

--- Adjustable working speed. If your feeding material is wet, you can adjust the chain speed, and takes long time to remove the moisture

--- Energy saving, it mainly use gas which produced from Dry Distillation process as fuel to heat

--- Easy to operate. One people is OK.

--- Zero air pollution

--- This machine includes PLC, it can control whole process autonomic

Advantages of Rotary kiln:

The machine adopts double return more bypass double channel SY type structure design, mainly composed of primary drying device, and cooling parts,and water cooling discharging, flue gas recycling part, water dust removal, gas condensation part.Channel SY type design and use of flue gas waste heat reclycling which is once again raised the thermal efficiency;the equipment of the heat utilization rate reached more than 90%. The whole machine adopts PLC control.we can use proper material to control the carbonization period according to material’s moisture and pellet size.

 

Working principle of Rotary kiln:

This machine adopts double return more bypass double channel SY type structure design, mainly composed of primary drying device, and cooling parts and water cooling discharging, flue gas recycling part, water dust removal, gas condensation part. Channel SY type design and use of flue gas waste heat recycling which is once again raised the themal efficiency. The equipment of hear utilization rate reaches more than 90%. The whole machine adopts PLC control device. We can use proper material to control the Dry distillation period according to material’s size and moisture.
