Modeco Premium 2
Synergy-Dream has developed the latest model of the ModEco Premium 2 kiln, which is capable of producing a large percentage of premium charcoal (restaurant fraction) with a capacity of 30 to 40 tons per month. The main tasks in the development of the restaurant fraction charcoal kiln were to accurately calculate the operation of the coolant and to ensure convenient and practical unloading of the finished product.
This kiln can be transformed into the ModEco Premium 3 model by adding retorts, which allows for increased production capacity.
The kiln consists of a kiln and 4 stationary retorts, which are connected into a single unit by a directional flow of heat carrier.
The kiln is a metal body, the walls and bottom of which are lined with high-temperature insulation. The following materials are used for the lining: ceramic fiber with a working temperature of up to 1250 degrees, ceramic tiles with a working temperature of up to 1250 degrees, chamotte brick SHА 5. Also, metal parts made of refractory steel AISI 310 and partially AISI 321 were used in the kiln construction.
The retort body is thermally insulated, which ensures a constant and uniform temperature in all its parts. Wood pyrolysis takes place directly in the middle of the retort. The inner walls of the retort can be made of different high-temperature steel (on request). In the construction of the ModEco Premium 2 we used steel grade 09 G2C, which ensures a long-term service life of the retort (at least 10 years).
Preliminary drying is not provided for this model, and therefore the capacity (with wood moisture content up to 60%) will be from 30 to 40 tons per month.
If the incoming raw material has a moisture content of up to 15%, then all performance parameters can be increased by 100%.
The ModEсo Premium 2 charcoal kiln can be operated both with an automated control system (ACS), where the ACS controls the kiln operating modes and keeps the temperature within the set parameters, and in manual mode, where the kiln operator uses thermocouple readings to control the process.
When coal is unloaded, the lower hatch and gate open. Coal is unloaded into metal stabilization tanks. To stabilize the coal, metal stabilizers are used, which, subject to the cooling and stabilization regulations, ensure proper preparation of coal for packaging.
