Charcoal kiln CK-7 "EURO"

Charcoal kiln CK-7 “EURO” is a continuation of charcoal kilns of the “EURO” series, which are designed forlow-temperature pyrolysis of carbon-containing materials (of plant origin) in order to obtain high-quality charcoal and thermal energy. The model went on sale in 2018.

The following advantages of the kiln should be mentioned:

  • Reduction of heat loss due to the use of the newest thermal insulation materials
  • Quick start-up
  • Low weight and easy transportation
  • Possibility to send two kilns in one vehicle
  • High productivity and COMPACT SIZE
  • Reliable, maintainable and safe construction of the kiln
  • Easy and safe operation
  • Absence of emissions during operation
  • Full mechanization and automation of the operation process
  • Low power consumption
  • Possibility to obtain thermal energy
  • The cost includes commissioning works and staff training
  • Warranty period is 12(24) months
  • Charcoal holds the shape of the raw material
  • Less than 1% of siftings
  • The kiln meets all modern requirements
  • The kiln is delivered practically fully assembled

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%.
