Management of Brazilian hardwood species (Jatoba and Garapa) wood waste biomass utilization for energy production purposes
ArticleIn the
Federative
Republic of Brazil,
Jatoba (
Hymenaea courbaril
) and Garapa
(
Apuleia
leiocarpa
) trees
are intensively harvested
. The yield of one log is approximately
45
–
55%, which
indicates a
great
amount of produced wood waste biomass.Present research
monitored the suitability of wood waste biomass from Jatoba and Garapa trees for bio
–
briquette
for solid biofuel production.
The research
was focused on chemical parameters,
and
energ
y
potential of such biomass kinds. Jatoba wood waste biomass was used for the
production
of bio
–
briquette fuel and its final mechanical quality was investigated by determination of their
mechanical quality indicators.
Results of chemical analysis (in wet b
asis) exhibited
great
level of
ash content in case of both species (
Jatoba
–
0.31%, Garapa
–
3.02%), as well as high level of
energy potential; net calorific value
equal to 18.92

for
Garapa. Analysis of elementary
composition proved following levels of oxygen content: J
atoba
–
41.10%, Garapa
–
39.97
%. Mechanical analysis proved bio

. Most important quality indicator, the
mechanical durability DU,
unfortunately,
occurred at a
lower
level; DU
=
77.6% compared to the
minimal level of bio

briquette fuels intended for commercial sales which must
be >

analysis proved materials suitability for energy generation purpose with certain limitations which
can improve by changing production parameters of
briquetting
