Charcoal kiln CK-1 “EKKO” is designed for low-temperature pyrolysis of carbon-containing materials of plant origin in order to obtain high-quality charcoal and heat energy.

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.)

The high level of efficiency of CK-1 “EKKO” 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-1 “EKKO” 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.

Mechanization and automation of CK-1 “EKKO” 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.

GreenPower charcoal kilns of the "EKKO" series are unique due to the fact that not the material, but the process is moved from one chamber to another. It provides high performance at relatively low cost.


The following advantages of the kiln should be mentioned:

  • Low price – high quality!
  • Possibility to transport two kilns in one vehicle
  • High productivity and COMPACT SIZE
  • Small weight
  • Reliable, maintainable and safe construction of the kiln
  • Absence of emissions during operation
  • Full mechanization and automation of the operation process
  • Low power consumption
  • Charcoal holds the shape of the raw material
  • Possibility to obtain thermal energy
  • The cost includes commissioning works and staff training
  • Possibility to arrange central control of the kiln complex
  • Less than 1% of siftings
  • The kiln is delivered practically fully assembled


Dimensions of the kiln

Description of the kiln

The charcoal kiln consists of 2 chambers connected to the chimney with a deflector, and to the furnace. The kiln includes 4 trolleys, platforms for moving the trolleys, trestles for loading raw material and unloading charcoal, and an electric winch. The chambers can be operated in the “DRYING” and “PYROLYSIS” modes. Each chamber contains 1 trolley and has a loading hatch for loading/unloading the trolleys. The chambers are equipped with channels used to release steam emitted during the drying of raw material, and gas emitted into the furnace during the process of pyrolysis, which ensures the maintenance of the drying and pyrolysis processes. Complete combustion of the pyrolysis gas ensures environmental safety of the process. A water seal is connected to each chamber in order to stabilize the pressure inside the chamber. All control elements are mechanized. A permanent record of the main operating parameters is held, which allows to conduct analysis of the kiln operation.

Kiln productivity

Raw material Charcoal, tons per month
 Freshly cut wood 20-30*
 Pre-dried wood 30-40*
 Fuel briquettes 40-50*

The standard delivery set of the charcoal kiln CK-1 "EKKO" can be loaded into a truck with the trailer volume of not less than 86 m3Two kilns can be loaded into one truck provided the trolleys are transported unassembled. It is possible to ship one set of the CK-1 "EKKO" installation in a 20 ft container or two sets in a 40 ft container.

Model of the production site

Operating parameters of the kiln
Parameter name Unit of measure Value
 Maintenance staff for 1-3 kilns ppl. 2-3
 Power consumption, no more than kW per hour 1
 Firewood consumption of the furnace, no more than* m3 per 24 hours 0,3
 Dimensions, 20ft container: length, width, height (with afterburner) m 2,3х2,3х5,8 (2,3х2,3х7,0)
 Duration of the complete cycle h 6-20
 Weight t 10
 Warranty period months 12

* 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%.
