Requirements for equipment for carbonization
IMPORTANT! Bio-Kiln is a 100% complete, fully commercialised system which is produced in three versions. The installation was developed by GreenPower during 2015-2017; from the end of 2017 to 2019 the furnace passed all industrial tests. In 2019, the mass production of Bio-Kiln began. Bio-Kiln is not an experiment!
The charcoal-burning complex based on the BIO-KILN carbonization unit allows automating the entire production process of producing charcoal: the processes of loading raw materials and unloading finished charcoal, it also makes it possible to automatically control the content  carbon in charcoal, minimize ash content, increase the output of charcoal, eliminate the influence of the human factor and achieve consistently high performance indicators of the furnace.
The main advantage of BIO-KILN: constant quality parameters and output volumes of the product are readily achieved, since charcoal production occurs without human intervention in the technical process, namely in automatic mode.
Raw materials: Pits, shells and nuts of fruit trees; wood chips; bamboo; cones and other raw materials of plant origin with a fraction of 5-30 mm and humidity less than 15%.

Received products:

- charcoal as a raw material for the production of briquettes for BBQ,
- hookah charcoal (shisha pipe charcoal),
- charcoal as a raw material for the production activated carbon;
- ready-made BIO-Char from plant waste, for use in agriculture &  horticulture.

Received products from charcoal

The following advantages of the kiln should be mentioned​:

  • Reliability of the kiln. The carbonization equipment is made 100% from refractory materials.
  • Environmental Safety – zero noxious emissions
  • High efficiency, compact size
  • High productivity: 15-100 t / month, depending on the raw materials and kiln model (Bio-Kiln 1, 2 or 3)
  • Continuous production process
  • Minimal personnel intervention in the production process
  • Recoverable thermal energy, with the possibility of using it for: drying of raw materials, drying of coal briquette, local heating
  • Low power consumption (0.01kW) for full kiln autonomy
  • Remote Control Capability
  • Full process automation
  • Non-volatile carbon content in coal from 86% to 94% - according to requirements of the enterprise
