Drying Equipment

Excess heat recovery unit for the carbonization furnace BIO-KILN

It is used to obtain excess heat and then use it for various purposes – from drying raw materials to heating buildings.

Preliminary dryer for the carbonization furnaces EKKO

It is used to obtain excess heat from the process and its application in the drying system outside the carbonization chamber in the trolleys.

Pre-drying chamber for carbonization furnace

Used in cold season or rainy season or outdoor production, ensuring the stability and quality of the drying process.

Rotary Dryer (Drum Dryer)

It is designed for drying wood chips, sawdust and agricultural waste, reducing their moisture content for subsequent use in production processes.

Wood drying complex

Designed for quick drying of industrial wood, including firewood and raw materials for carbonization.

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.

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.
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.
