| Abstract |
Coconut jelly, the solid waste from ready-to-drink industry, was used to produce solid fuel pellets. The pellet forming was done by a single 10-ton hydraulic press unit without any binders. The characteristics of the pelletized fuel including diameter, length, bulk density, pellet density, proximate analysis, heating value, energy density, combustion rate, heat release rate, compressive strength and durability were investigated. The result showed that pellets had average diameter and length of 10 mm. The pelleting could significantly improve the bulk density from 30 kg/m3 of original form and 70 kg/m3 of grinded form to 659 kg/m3. Proximate analysis values of pellets (moisture 8.05 wt%, ash 2.06 wt%, volatile matters 77.04 wt% and fixed carbon 12.85 wt%) indicated good combustion parameters. The heating value of pellets was 15,995 kJ/kg which increased by 19.05% from its original form. Pellet density was 1,100 kg/m3 and then resulting in energy density of 17.59103 MJ/m3. The fuel pellets also increased 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 its original form. The pellet had the high durability (98 wt%) and high compressive strength in horizontal direction (484 N/cm2). Overall, the properties of coconut jelly pellets meet the requirements of Thailand 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. |
