EcoForest
There is a need to recycle coconut shells globally, and one of the ways to process them is through pyrolysis to produce coconut charcoal. This charcoal is an environmentally friendly and renewable energy source, with a high calorific value, low ash content and long burning time.
Synergy-Dream has developed a special kiln for producing high-quality charcoal from coconut shells. This furnace does not require preliminary grinding of the shells and can also be used for the charring of small woodworking waste with a fraction of 50 mm-500 mm without selection. The furnace capacity is from 32 to 50 tons per month, depending on the moisture content of the raw material. There are no harmful emissions into the atmosphere.
The furnace consists of a furnace, six mobile retorts and a logistics system that ensures the retorts are moved between the loading, pyrolysis, settling and unloading zones.
The furnace is a metal body with walls and bottom 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, and fireclay brick SHА 5. The furnace is also constructed with metal parts made of AISI 310 and partially AISI 321 refractory steel.
The body of the retort 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).
The raw material is loaded into the retort using a belt conveyor: the retort lid is opened and the raw material is poured inside. The finished product is unloaded using a special tipper device. First, the retort is placed on the tipper platform, after which its lid is opened, and a special hoist located on the tipper lifts the lower part of the retort, which allows it to turn over and pour the finished product into a stabilization tank.

* – the value of the parameter depends on the season, moisture content of the raw material.
** – the parameter value depends on the moisture content, type and fraction of raw materials.
*** – the parameter value depends on the number of units at one site:
1 plant – 2 people per shift
2 plants – 2 people per shift
3 plants – 3 people per shift
