- for cylinder briquettes (NESTRO type)
- produce solid fuel with calorific value 4400-4700 kcal/kg (the same as coal)
- get the 100% ecological briquette, no glues, no adhesives or other chemicals
- utilize industrial wood and biomass wastes
- create eco-friendly source of energy from renewable sources
wood waste: woodchips, wood shavings and sawdust of hardwood and softwood
agricultural waste: sunflower, buckwheat and rice husks, walnut shells, peanut shells, olive pits, straw, cane, miscanthus, bagasse etc.
|Moisture of raw material, %:||8-15|
The main components of briquetting process are: hopper 1, screw feeder 2, working zone of the press 3, cooler 4, base 5 and control panel 6.
Hopper 1 is a feeding assembly consisting of three interconnected sections.
Inspection port 9 helps to watch the product in the hopper. Cover 10 is used for cleaning from any foreign particles. Gear motor 11 is installed on the shaft of the mixer 8. Mixer consists of four knifes which mix the product constantly.
Dried to 12% raw material is fed to hopper. Screw feeder conveys the mixture into the pressing zone where the pressure and temperature increase. The feedstock is forced through a forming die as a result briquettes of diameter 70 mm are made.
There is no glue or other additives in our technology. The temperature is so high that lignin is released thus binding the material into a solid briquette with high density.
The moisture content of the raw material is 8 – 15 % while the ideal moisture for most wood material is 10-12%.
