Abstract:
This study aimed to develop fuel briquette from biomass residues (parchment and
silver skin) of Mae-Ton Fresh Coffee SMEs by using mechanical extruder and manual
compactor tool. Physical and chemical properties, heating value, and the effectiveness
of fuel briquette use were examined. Results showed that biomass residues offering
potential source of heat energy could be manually compressed to form fuel briquette.
The briquette with mixed starch binder at 10.5% (by mass) was an appropriate condition
and was produced at a rate of 1 briquette per 1 - 1.5 minute by using manual compactor
technique. With good visual and physical quality (straight and smooth briquette form)
and easily stored fuel, the heating value gained was 4,160 Cal/g. With burning the
briquettes (5 pieces/250 - 260 g) the duration of ignition, boiling, and combustion were 2,
10, and 53 min respectively. It produced red flame, smokeless and odorless fuel
briquette without fire flakes.
