The
aim
of
the
research
was
to
determine
the
moisture,
combustible
and
ash
content
in
selected
biofuels,
in
dependence
on
temperature
by
the
means
of
gravimetric
method.
For
this
purpose,
the
furnace
Nabertherm
L9/11/SW/P330
was
used.
Analyzed
samples
cons
isted
of
crushed
biomass
which
is
used
in
small
heat
sources
(e.g.
spruce
wood,
cherry
wood,
apple
wood,
black
locust
wood)
with
bark
and
without
additives.
Biomass
for
larger
heat
sources
(woodchips
cuttings
from
coniferous
trees),
sawdust
mix
(plum,
cher
ry,
walnut,
apricot,
apple)
and
pellets
(90%
spruce
and
10%
fir)
were
also
analyzed.
The
results
are
processed
graphically
and
enable
to
characterize
the
tested
fuels.
The
highest
content
of
combustible
was
found
in
spruce
wood
sample
without
bark
(99.889%
),
the
lowest
content
of
combustible
indicated
cuttings
from
coniferous
trees
(88.402%).
Gravimetric
experiments
were
supplemented
by
DSC
measurement
of
selected
samples
on
calorimeter
Toledo
DSC822e.
The
graphic
courses
of
reactions
are
provided
up
to
500
°C.
