Abstract

Abstract
The combustion process of Albizia falcataria (AF) sawdust with the addition of natural zeolite (NZ) was observed experimentally
using
PT
1600
LINSEIS
Simultaneous
thermal
analyzer
(STA).
The
results
showed
that
alkali
metal
and
alkaline

metal
earth
in NZ play
an essential role
in the
process
of decomposing
the
Hemicellulose AF molecule. The results
of

the
molecular analysis
show
that
the
chemical
balance of the
mixture
determines
the
combustion
temperature.
Excess
NZ

becomes
a thermal
burden
which
slows
down
the
combustion
reaction
because heat does not
sufficiently
activate
alkali
metal

and
alkaline
metal
earth
in NZ. In a small amount, NZ is less involved
in the
AF decomposition
process.
It shows
that
a

mixture
of AF and NZ can increase
combustion
kinetic
in the
right
mix. Addition
of 15–20% of NZ decreases
the
ignition

temperature
within
faster
burning
rate.
Activated
alkali
metal
and alkaline
metal
earth
decompose
hemicellulose faster
so

that
they
burn
completely
in minimizing pollutant
and maximizing LHV.
Greater
NZ completes
the
decomposition
much

earlier
so that
at the
resting
time of the
process
NZ slightly
absorbs heat sinking LHV.
The drastic
reduction
of Ca due to

NZ
make
the
fuel
is
suitable
for
boiler
because
Ca
is
responsible
for
agglomeration
and
corrosion.
