1-3 charcoal kilns, depending on the level of automation, are serviced by 2-5 people - one operator and 1-4 assistant(s). The capacity depends on the parameters of the raw material and is up to 45 tons of high-quality charcoal per month while processing wood and up to 70 tons per month using fuel briquettes (Pini-kay, ruff, nestro). The design of the charcoal kiln is 100% safe and time-tested. Ideal for operation on the territory of woodworking enterprises for the purpose of processing industrial waste into the charcoal. The most important advantage is the high quality of the produced charcoal. During the pyrolysis process wood and fuel briquettes practically do not change their shape and structure, the amount of unconditioned products and screenings does not exceed 1%! While operating it is recommended to use mobile platforms for moving trolleys around the site. We also recommend to use the stationary trestles for loading of the raw materials, cooling charcoal in the trolleys and unloading the charcoal. In addition, the platform can be equipped with a special chamber, which significantly reduces the cooling time of the trolleys, this allows to minimize the number of trolleys used to ensure a continuous process.
Pre-prepared wood (Ğ¤<150 mm, length <330 mm) or fuel briquette are placed into the trolleys. If Pini-kay briquettes are used as the raw material, it is recommended to use the special grids in order to preserve their appearance during the process of carbonization. After that, the trolleys with raw materials are moved into the drying/pyrolysis chamber, which is in the "drying" mode. Each chamber is loaded with 3 or 4 trolleys (depending on the model of the charcoal kiln), the capacity of each trolley is about 1 m3 / wood or up to 350-750 kg / briquettes.

When the loaded raw material is completely dry, that is shown by the readings of the temperature sensors, a "pyrolysis" mode is set in the chamber, while the other chamber it is switched to the "drying" mode. The pyrolysis gases are conducted to the furnace chamber where they are burned to maintain the process. The residual heat from the chamber in the "pyrolysis" mode is conducted to the chamber in the "drying" mode and the excess heat released as a result of the exothermic reaction is used to generate thermal energy. The termination of gas evolution and the indication of the temperature sensors indicate the end of the pyrolysis process. Then the camera in the "pyrolysis" mode is switched to the "drying" mode, the camera is in the "drying" mode - into the "pyrolysis" mode, this happens synchronously. At the same time, the trolleys with the charcoal are moved from the chamber in which the process of "pyrolysis" is completed, to the cooling site. The trolleys loaded with a new portion of raw materials for pyrolysis are loaded into the vacated chamber with the "drying" mode. The cycle is repeated. After complete cooling of the trolleys, charcoal is unloaded for stabilization.
* Due to the fact that preparation of raw materials, loading of firewood into the trolleys, cooling of the charcoal in the trolleys, the unloading of the charcoal, pre-packaging and packaging are the processes that occur "outside the kiln", the working cycle includes the processes of "drying" and "pyrolysis" of wood. Declared capacity of the charcoal kiln CK-5 EURO is achieved on condition of competent organization of the entire technological process - from the preparation of raw materials to the packaging of finished products!
