Continuous charcoal kiln BIO-KILN

BIO-KILN is an environmentally-friendly continuous charcoal kiln with the possibility of constantly generating thermal energy from bulk waste of plant origin with the fraction of 10-50 mm and humidity less than 20%.

Raw material for BIO-KILNvarious nutshells, fruit pips, wood chips, bamboo, bushes, etc.

The followinggg adddvvvantaggges of the kiln shouuulddd bbbe mentioneddd:

● Environmental safety● High efficiency and compact size● High productivity (25-50 tons per month, depending on the raw material)● Continuous 24/7 production● Autonomous process (does not require manual operation) ● Generation of thermal energy● Low power consumption● Possibility of controlling the equipment remotely● Possibility of making the process fully automated● Content of fixed carbon in charcoal - 65-94%

Kiln description

Crushed (10-50 mm) and pre-dried raw material (withthe moisture level of <20%) is loaded into the sluice feeder. Afterwards it enters the loading hopper that is located in the upper part of the kiln. The active area of the kiln consists of vertical downtube-ducts ending withdampers for unloading the finished product. Raw material descends the channels during the processes of preheating, pyrolysis, calcination and stabilization of charcoal. Gases released from the kiln enter the channel for flue gases andthen move on to the afterburner, where they are combusted. The afterburner design provides full combus-tion, ensuring the environmental safety of the installation and preventing the release of harmful emissions into the atmosphere. Charcoal unloading is conducted with the help of the dampers located at the bottom of the kiln – in the stabilization zone. Each channel has several dampers that ensure the portioned unloading of the producedcharcoal. Charcoal is unloaded into a special cart withwheels. After the cart is filled, it is replaced with an empty one. The unloaded charcoal is air-stabilized in the trolley, after that it is packed in containers according to the requirements of the Customers.

Main elements of the continuous charcoal kiln BIO-KILN

1. Loading hopperRaw materials for pyrolysis is loaded into the hopper. 2. Charcoal kilnCore processes take place inside the kiln: drying/pyrolysis/calcination. As the raw material moves down, it turns into charcoal. Raw material moves down dedicated ducts, isolated from direct ignition. 3. Slide dampers for charcoal dischargeUsed for the charcoal unloading into the hopper for the charcoal stabilization. 4. Stabilization hopperDeveloped for the charcoal stabilization before its unloading. 5. TrolleyThe charcoal is unloaded into the trolleys for the further air degassing and cooling. 6. AfterburnerPyrolysis products are burnt in the afterburner in order to provide the environmental friendlyness of the process. 7. Chimney, 8 rmIt is installed on the afterburner in order to provide the kiln operation without additional fan and smoke exhauster. 8. DaisDesigned for the convenience of loading of the raw materials into the hopper. 9. Auxxxiliary equipment. Additionally, the kiln can be equipped with:

● Storage hopper for raw materials● Conveyor or noriya for loading of raw

materials in the bunker of the kiln● Closed and open augers for cooling

and stabilizing charcoal● Feedstock level sensor in kiln hopper● Actuating mechanisms for opening

and closing dampers for unloading● Automated control system, provide full

automation of the process.● Heat exchanger: gas – water, for pro-

ducing hot water or other heat transfer fluid; gas-air, for generating hot air.
