Carbonization furnace EKKO
Who are the main consumers of EKKO?
  • Enterprises engaged in the harvesting and processing of timber, tree plantations.
  • Woodworking enterprises.
  • Plantations: bamboo, eucalyptus, energy willow, etc.
  • Agricultural enterprises, including gardens: all possible agricultural wastes.
  • Other enterprises produce biomass (lignin, peat, etc.), waste of plant origin.
The main consumers of finished products (charcoal)?
  • BBQ
  • Metallurgy
  • Production of silicon
  • Production of activated carbon.
  • BIOCHAR – eco fertilizer
  • Other industries consumers of charcoal
What processes are used to produce charcoal?

The charcoal production process uses processes outside of the furnace and using a carbonization furnace. 

  1. Processes outside the furnace
    • Preparation of raw materials for the carbonization process: grinding of raw materials, for wood – cutting and splitting.
    • Pre-drying of raw materials, it is possible to use air drying “sun and wind”, also “contact dryer” – a device developed by GreenPower, which uses excess heat from the carbonization process to pre-dry the raw material. Pre-drying is not mandatory for the process, but only affects the total productivity of the furnace, in the basic design of the furnace, a drying mode is provided.
    • Loading raw materials into trolleys
    • Loading trolleys with raw materials into the EKKO furnace chamber.
    • Unloading trolleys with charcoal from the EKKO furnace chamber.
    • Charcoal cooling in trolleys.
    • Unloading charcoal from trolleys.
    • Stabilization of charcoal – its interaction with atmospheric air, to ensure the fire safety of charcoal, in order to eliminate the self-ignition factor.
    • Packing of charcoal in a package for delivery to Consumers.
  2. Processes in the furnace
    • Drying of raw materials, removal of moisture (100-150°C) and the initial stage of pyrolysis (150-250°C). If pre-drying outside the furnace is used, this is reflected in the duration of this process. With a pre-drying system, partial moisture removal takes place outside the EKKO furnace chamber.
    • Pyrolysis stage – raw material carbonization (250-450°С)
    • Calcination of charcoal (450-550°C), if it is necessary to increase the content of non-volatile carbon > 77%

The temperature regimes in the furnace are regulated automatically or by the operator, depending on the requirements for the content of non-volatile carbon in charcoal. The change of drying/pyrolysis modes is carried out by the operator manually at the end of the mode according to the indications of the temperature sensor.
