Continuous charcoal kiln BIO-KILN

Download the description of BIO-KILN (pdf)

 

In 2015 GreenPower developed a new unique technology of producing charcoal and BIO-CHAR from bulk waste of plant origin.

BIO-KILN is an environmentally-friendly continuous charcoal kiln with the possibility of constantly generating thermal energy.

The following advantages of the kiln should be mentioned​:

  • 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%

Description of the kiln

BIO-KILN is a continuous charcoal kiln for processing bulk waste of plant origin with the fraction of 10-50 mm.

Crushed and pre-dried raw material (with the 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 downhole shafts-channels that end with dampers for unloading the finished product. Raw material descends the channels during the processes of preheating, pyrolysis, calcination and stabilization of charcoal. The active zone of pyrolysis products combustion is located between the channels for raw material, and the heating of the raw material is conducted through the wall. The active area of the kiln is designed in such a way that several zones are arranged along the entire height of the channel for raw material. The are four zones in the active area of the kiln.

Zone 1 – zone of stabilization and cooling of charcoal with a temperature of 300-600°С

Zone 2 – calcination zone, where the temperature is 450-600°С

Zone 3 – zone of raw material pyrolysis - 250-450°С

Zone 4 – zone of raw material preheating - 100-250°С

Scheme of the kiln

 

Gases released from the kiln enter the channel for flue gases and then move on to the afterburner, where they are combusted. The afterburner design provides full combustion, 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 produced charcoal. Charcoal is unloaded into a special cart with wheels. After the cart is filled, it is replaced with an empty one.
