Front loader sends wood powder into a special vibrating sieve. After sieving materials follow to drying into a circular aerodynamic reactor. Here, the biomass is prepared for compressing.
After the reactor, the part of material which moisture level doesn’t surpass 2-3% gets transported to a cyclone collector where it undergoes deposition and then, again by screw conveyor, goes into a bunker. Extruders produce about 3 tons of high-polymeric briquettes in an hour. The briquettes are set on carriages and a forklift transports them to carbonization.
Such a briquette may stay in water up to several days without being damaged. The pressing engines’ work takes less energy - not more than 40kW*hours/ton of product. It is significantly cheaper than hydraulic or pellet engines. With them you will avoid having such problems as unstable working process or fast exhaustion of equipment details.
Ready-made product’s moisture content doesn’t surpass 2% and density is 1,26-1,30 kg/dm3.
4 carriages are loaded into the carbonizing oven. There is a high-capacity heat exchanger inside, as well as a fan. They contribute to pyrolysis reaction of briquettes, meanwhile the gas burns out in the dryer heat generator and the resulting energy sets off to dry wood powder. The oven itself functions using energy of thermal decomposition of wood residues. The amount of heat gained from pyrolysis gas burnout depends on the oven’s work mode.
At this stage, briquettes are solidified after cooling. Then the product is packaged.
Ready-made charcoal briquette features very high density. Because of that fuel is easily transported in 40 ft containers with load weight about 25 tons.
