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.

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 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 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 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 coal 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 EKKO-2.

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

Description of the kiln

The charcoal kiln consists of 2 chambers connected with the furnace, afterburner and chimney. 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. 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.

9. Gas butterfly valves of chamber A/B
10. Steam valves of chamber A/B
11. Water seal of chamber A/B
12. Heat carrier channel of chamber A/B
13. Control panel and control and measuring devices

  1. Trolleys
  2. Mobile platform
  3. Trestle
  4. Portable trestle
  5. Rails for the mobile platform
  6. Electric or manual winch

There are 2 types of the trolleys for mechanization of processes of loading/unloading of raw materials/charcoal - with front and vertical 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.

Kiln productivity

Raw material Charcoal, tons per month
 Freshly cut wood 25-30*
 Pre-dried wood 30-40*
 Fuel briquettes 45-55*

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 m3Two kilns can be loaded into one truck provided the trolleys are transported unassembled. It is possible to ship one set of the EKKO-2 installation in a 20 ft container or two sets in a 40 ft container.

Operating parameters of the kiln
Parameter name Unit of measure Value
 Maintenance staff for 1-3 kilns ppl. 1-3
 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%. It is possible to increase the productivity of the kiln using Contact drying - a device for preliminary drying of raw materials.
