Turning waste biomass into briquettes and pellets
To improve energy efficiency, transport, and storage of biomass it is necessary to compress wood waste - sawdust, wood shavings, forest residues, wood waste, ground, or crops such as peanut shells, rice hulls, brachiaria hay, corn stove, coffee husks and other organic wastes and lignocelluloses.
During the briquetting process, high mechanical pressure is generated (200 MPa), which causes an increase in temperature by around 100 to 150 ° C.
The agglomeration process demands a water content between 8% and 15% and a maximum particle size of 0.5 to 1 cm.
When you have waste with these characteristics, the manufacture of briquettes becomes very cost-effective (40-60 kWh / t). If you need to dry or grind the waste beforehand, the costs increase considerably.
Equipment that uses a hydraulically driven piston.The material to be compacted is fed laterally by a screw.A front piece to the piston opens the briquette expelled when it reaches the desired pressure
