Jute Stick Carbonization Furnace

Capacity:  300-1000 KG/8H


Application: suitable to drying


Below is Jute Sticks Charcoal Making Machine Carbonizing Process:

Dingli biomass dry distillation carbonization furnace is composed by carbonization furnace body, furnace cover, inner tank, material cage, combustible gas return pipe, exhaust pipe, flue gas dust removal device, tank lifting device and thermometer. 

The furnace adopts the principle of anaerobic dry distillation to remove the volatile substances in the biomass, and achieve the purpose of biomass carbonization. 

Carbonization process have four steps: charging sealing furnace - preheat drying - anaerobic carbonization - cooling carbon.


Below is Jute Sticks Charcoal Making Machine Working Principle:

Charging sealing furnace is putting the biomass core rods, shells and other materials into cage. The cage is divided into two or three layers. in turn into the inner tank, cover, lock the buckle, lifting the charging tank into the furnace. Preheat drying in the furnace with wood and other fuel heating, slowly heated from room temperature to 220-250 ℃, the process time 1.2-2.0 hours (according to the material moisture content, density, particle size determines the specific heating time), and discharge the material moisture and the air in the tank.

Anaerobic carbonization is the furnace temperature to the beginning of weak yellow smoke in the smoke pipe (hydrogen and other volatile substances) discharge, that is the beginning of carbonization, recovery of combustible gas into the furnace ignition, adjust intake air, maintain the tank temperature 300-450 ℃ for 2.0-3.5 hours (according to the carbonized material density, particle size, and carbonization depth requirements determine the specific temperature and carbonization time). 

When the furnace is natural flameout, namely for the end of carbonization. Cooling out the carbon is hanging out of the tank from furnace, into the cooling area of natural cooling or spray water cooling, until the inner tank temperature dropped to below 50 ℃, then open the cover out of charcoal. The total furnace temperature and carbonization time is 3.5-5.5 hours. It can complete 3-6 furnace time in 24 hours. 

Exhaust gas through dust collector treatment to reach discharge standards. 3 sets of carbonization furnace in parallel use, peak shifting carbonization, which can be completely used volatile gas heating carbonization furnace, without using additional fuel.

1. The carbonization furnace tank and cage adopts 304 stainless steel. The price will be negotiated additionally.
2. The unit price does not include lifting frame and electric hoist, denominated separately.
3. Carbonization capacity, temperature and time is decided by the material moisture content, density, particle size and carbonized depth (volatile and reserve amount). While adjust the carbonization process parameters or change the raw material, the equipment daily output will be changes.
4. Dingli company is responsible for the client's site planning, process design, equipment installation guidance and training etc.
