Charcoal kiln EKKO-2

Charcoal kiln EKKO-2 is designed for low-temperature pyrolysis of carbon-containing materials of plant origin in order to obtain high-quality charcoal and heat energy


Charcoal kiln EKKO-2

The high level of efficiency of CK EKKO-2 is achieved by using modern heat-resistant insulating materials for the walls of the drying/pyrolysis chambers and the furnace, which gives the opportunity to quickly start the operating mode and significantly reduce the production cycle. The kiln is unique due to the absence of “thermal ballast” materials, such as sheet metal and refractory bricks, which are the basis of almost all charcoal kilns.

Reliability and maintainability of CK EKKO-2 is determined by the 15-year experience in manufacturing charcoal kilns, which helped to develop a reliable construction with a minimum service life of 10 years. During the development process, the possibility of quick and easy repair of all the kiln units was ensured.

Automation of CK EKKO-2 is achieved due to the fact that the kiln is equipped with a reliable time-tested system of control and measuring devices; automation of the operation process is also provided, as well as emergency modes in case of non-compliance with operating regulations.

Logistics and mechanization, the logistics system of the charcoal area should include the following processes: raw material procurement, loading of raw materials into the kiln, cooling and unloading of coal, as well as packing and storing coal. Competent logistics is already 50% of success, a detailed description of the elements of logistics for CK EKKO-2.

Raw materials

The technology allows to use various raw materials for pyrolysis:

  • Wood (firewood, lump wood waste of logging and woodworking industries)
  • Fuel briquettes (Pini-Kay, ruff, nestro, Nielsen)
  • Fruit pips (olive pits, grape seeds, etc.)
  • Agricultural waste (straw, reed, etc.)
  • Various nutshells (coconut, hazelnut, walnut, cashew, etc.)

Charcoal kiln EKKO-2 is designed

Description of the kiln

The kiln consists of 2 chambers connected with the furnace, afterburner and chimney. Each chamber has a loading hatch for loading/unloading of trolleys and contains 1 trolley. The chambers are equipped with gas-release channels that are used to release the gas, emitted in the process of pyrolysis, to the furnace and to the drying products into the atmosphere. The design of the kiln provides the modes of drying and pyrolysis. The standard delivery set of the kiln includes 4 trolleys, platforms for moving the trolleys, trestles for loading raw material and unloading charcoal, and an electric winch.

Complete combustion of the pyrolysis gas ensures environmental safety of the process. All control elements are mechanized. A permanent record of the main operating parameters is held, which allows to conduct analysis of the kiln operation.

Logistics elements of the working site

15. Trolleys.
16. Mobile platform for trolleys.
17. Stationary trestle for trolleys.
18. Portable trestle.
19. Rails for the mobile platform.
20. Electric winch.
21. Trolley tipper.


There are 3 types of the trolleys for mechanization of processes of loading/unloading of raw materials/charcoal – with front, side and top loading/unloading. For the convenience of the raw materials loading, as well as for cooling and stabilization of the charcoal inside the trolley and its subsequent unloading, stationary trestles are used. Furthermore, it is possible to use a conveyor for raw materials loading into the trolleys and a dumping device for the charcoal unloading from the trolleys. In this case, the most suitable option will be the trolley with the top loading of raw materials.

Raw materialCharcoal, tons per month
Freshly-cut wood25-30*
Pre-dried wood30-40*
Fuel briquettes (Pini-kay)45-50*

The standard delivery set of the charcoal kiln EKKO-2 can be loaded into a truck with the trailer volume of not less than 86 m3. Two kilns can be loaded into one truck provided the trolleys are transported unassembled. It is possible to ship two sets of the EKKO-2 installation into a 40ft container.

* The parameter values depend on the following factors: wood moisture content, wood species (minimum moisture content – poplar, maximum moisture content – hornbeam, Crimean oak) and size of the piece. Increased humidity (in comparison with the nominal level of 55%) significantly reduces the output and increases the firewood consumption of the furnace. At a relative humidity of 75% (freshly cut hardwood during the sap flow period) the productivity decreases by 15-20%. It is possible to increase the productivity of the kiln using Contact drying – a device for preliminary drying of raw materials.
