Results show that charcoal from sugar-cane bagasse fly ash can
be used to produce briquettes. This kind of briquette is a new option
of renewable fuel, and its utilization can reduce deforestation
for charcoal production or for use as wood fuel.
Results also show that the procedure adopted for the production
of briquettes based on charcoal powder from the ash of sugar-
cane bagasse and cassava starch as the binder is efficient,
yielding briquettes with properties that meet market technical
requirements.
Moreover, the most representative parameters are compatible
with or better than those parameters obtained utilizing other
sources of charcoal. The average briquette properties obtained
are: a calorific value of 25,551 kJ/kg, a density of 1.12 g/cm3, a
mechanical resistance to compression of >7 MPa and a residual
ash of 13.2% after burning.
