High Efficiency Vertical Carbonisation Furnace Biomass Charcoal Retort Kiln 3.3t

Product Specification

Charcoal Briquette Machine Carbonization Stove Vertical Carbonization Furnace Biomass Charcoal Retort Kiln

This hoist type carbonization furnace include the outer stove, inner stoves, hoist equipment and Purification tank. It adopts the structure of unique air storage chamber, to fully reuse the gas produced during the process of carbonization. The gas produced inside the carbonization chamber flows down through the vertical pipes visible on the outside of the stove. The pipes deliver the gas to the firebox under the chamber to aid combustion and continue heating the carbonization chamber from the outside, saving much fuel during the whole process. The charcoal can be hoisted outside, in this way the cooling time can be reduced much, thus, the productive efficiency increases a lot. It is the ideal choice for mass production of charcoal.

This wood carbonization stove is an efficient stove can change wood log, wood briquette, coconut shell and bamboo Palm shells etc directly into final charcoal,can working without electricity.

Raw material

Wood, wood log, tree branch, wood stick, wood waste, wood briquette, coconut shell, bamboo, corn cob, olive husk, palm kernel shell, cashew nut shell, etc.

Parameter of the hoist type charcoal kiln

Wood Carbonization Stove Main Parts:

n Inner stove:

n Consist of the stove tank body and the sealed top cap. Both of them are made of the heat resistance thermal steel. , and the three carbonization basket can be stack together, easy for loading and transporting ,and it will save a lot of space and transport charge.

n Hoisting equipment:

n it include the steel hoisting frame and the E-hoist .And it is easy for loading and unloading the stove, and can reduce labor intensity, and it can be avoid the high-temperature burn when lift the carbonization basket.

n Purification tank:

n This system is consisting of purification tank and the exhaust-heated cycle pipe. And Smoking purification tank are used for purify the smoking

(can not Burning) and filter the wood tar.

The smoking through the purification tank will Become water vapor, and it will not pollute the air.

Working Principle:

1) Arrange wood briquettes in furnace, leave 25 cm distance from the briquette to the roof of furnace

2) Close the door of furnace

3) Brn 10 kg wood briquettes, and put into furnace from the top holes.

4) Turn on the air fan

5) Leave a small gap at the top hole to supply a little air, this procedure lasts 6 hours, and during this 6 hours, make the gap smaller and smaller.

6) After 6 hours, watch the smoke from the chimney, compare the color of smoke, if the

smoke become transparent, close the gap completely.

7) Turn off the air fan.

8) Wait the stove become cool, this procedure lasts 6 to 8 hours

9) Open the door, and leave the stove, make sure the gas come out and then check if the

carbonizing is finished

10) If after 6 hours, the smoke is still strong, keep the air fan working, and leave the gap

until the smoke become transparent. Sometimes, this procedure last 8-10 hours.

11) At the end, if the carbonization is not complete, the wood briquettes don’t become

charcoal totally, ignite again, and do as the above procedure

12) The better quality of charcoal needs longer time of carbonizing, best charcoal sounds

like steel, and no smoke when burn.

Advantage of the hoist type charcoal kiln

1. Advanced carbonized technology, high production efficiency with short working time.

2. Carbonization temperature can be controlled and adjusted.

3. Recycle wood tar, wood vinegar and exhaust gas. After processing, gas can be used recycling fuel.

4. Small investment, energy saving, convenient maintenance, good environmental protection performance.

5. No open fire, totally dry distillation. Shunt can also dry burning boiler flue gas etc, truly the charcoal, gas and oil range of equipment.
