| Abstract |
Coconut jelly, the solid waste from ready-to-drink industry, was used to produce solid fuel pellets. Pelletization
was done by a single 10-ton hydraulic press unit without any binders. The characteristics of the pelletized fuel
including pellet dimensions, bulk density, pellet density, proximate analysis, higher heating value, energy density,
combustion rate, heat release rate, compressive strength and durability were investigated. The pellets had an
average diameter and length of 10 mm. Pelletization significantly increased the bulk density from 30 kg/m3
of the
original coconut jelly and 70 kg/m3
of ground dried coconut jelly to 659 kg/m3
of the pellets. Proximate analysis
values of pellets (moisture 8.05 wt%, ash 2.06 wt%, volatile matter 77.04 wt% and fixed carbon 12.85 wt%) indicated
good combustion parameters. The higher heating value of the pellets was 15.995 MJ/kg, which increased by 19.05%
from its original form. The pellet density was 1,100 kg/m3
and the resulting energy density was 17.59 GJ/m3
. The
fuel pellets also increased the combustion rate and heat release rate from 0.05 to 0.17 g/min and 672 to 2,719 J/
min, respectively, when compared with the original form. The pellets had a high durability (98 wt%) and high
compressive strength in horizontal direction (4.84 MPa). Overall, the properties of coconut jelly pellets meet the
requirements of Thai and European standards of the pellet properties for non-woody materials. Thus, coconut jelly
waste could be considered as a potential raw material to manufacture pellets as an alternative energy source. |
