biochar charcoal carbonization retort kiln

CARBONIZATION STOVE

Carbonization furnace is to carbonize the biomass briquette into wood charcoal.
Carbonization furnace for biomass charcoal can greatly increased carbonizing ratio (increased from about 88% to 99%) and shortened the carbonizing time (from 24 hours to 6 hours), and shows the features of easy operation, higher safety, high efficiency, and energy saving. This furnace is ideal equipment for wood briquettes to have anoxic distillation carbonization.

Introduction of the main parts:

(1) Outer stove
includes heating room (for heating the inner stove), furnace body and heat-keeping layer (it is made of the heat insulating material)

(2) Inner stove
Consist of the stove tank body and the sealed top cap. Both of them are made of the heat resistance thermal steel, three inner stove can be stacked together for saving space and shipping cost.

(3) Smoking recycle tube
During the process of carbonizing, there will be some smoke.( can be burning) the smoke can be collected and returned to the furnace.

(4) Purification tank
This system is consisting of purification tank and the exhaust-heated cycle pipe.

(5) Hoisting equipment
it include the steel hoisting frame and the E-hoist .And it is easy for loading and unloading the stove.

Carbonization: Put finished machine-made charcoal briquettes or wood logs directly into the Carbonization Stove to convert the sawdust briquettes into charcoal briquettes.

Working process:

How to produce charcoal? It divides into three processes:

1. Heat
After sealing work, use wooden wastes or gas to heat furnace. Primarily, 10 minutes big fire to burn, when the temperature reaches 90 degrees centigrade, turn to use slow fire to heat. It takes 80-120minutes for this process to reduce water vapor from your materials.

2. Pyrolyse
Keep heating, when the temperature reaches 180-235 degrees centigrade for 3-5hours, it will produce gas from this process. Reuse this gas as fuel to heat. The whole process is about 8hours. When the temperature reach highest and it reduces, the dry distillation process will finished.

3. Cooling
Hang the Inner pot outside, and seal the pipes of cover. Let it cool naturally. Cooling time is longer, the quality of charcoal is good. When the temperature lowers than 50 degree, you can take charcoal out. Otherwise, the charcoal will burn again when met oxygen of air.

Why it is ECO-FRIENDLY ???

1. Smoking purification system are used for purify the smoking (can not burning) and filter the wood tar. The smoking through the purification system will become water vapor.

2. During the process of carbonizing, there will be some smoke.(can be burning). The smoke can return to the furnace after purification for heating use again.

Wide use of smokeless charcoal:

♦ Charcoal in industry: It is mainly used in combining carbon of industrial materials, metallurgy, and the carburizing carbon of chemical industry.

♦ Charcoal in agriculture and animal husbandry: It can raise the soil temperature, maintain soil moisture, mitigate the organic fertilizers and improve soil PH.

♦ Charcoal in life: People often use charcoal heating, barbecue, as well as the fuel used to the tea and tobacco drying.
