Abstract

Fuel pellets made from biomass is considered as a solid fuel that is also an alternative fuel which can substitute for the current fuels and can be considered as a fuel that has sustainable production. This research is the study of the production of fuel pellets from Teak sawdust blends with Cajuput leaves at five proportions by weight of Teak sawdust 100%, Cajuput leaves 100%, Teak sawdust 75% +Cajuput leaves 25%, Teak sawdust 50% +Cajuput leaves 50%, Teak sawdust 25% +Cajuput leaves 75% . The pellets were produced by a grinding and pelleting machine at three different speeds of 200, 250, and 300 rpm. After that, the quality of fuel pellets was evaluated by the physical properties as pellet dimensions, particles and bulk density, as well as moisture content and durability. The results show that blending proportion of Teak sawdust 75% and Cajuput leaves 25% provided the appropriate fuel pellet properties.

Highlights

Wood is the primary source for solid fuel, nowadays the number of trees has decreased dramatically
The all high heating value (HHV) values received from oxygen bomb calorimeter (IKA, Model C1) according to DIN 51900-1 with three duplicates for each condition
Fuel pellets made from Teak sawdust blends, with Cajuput leaves at five proportions, the physical properties were evaluated

Summary

Introduction

Wood is the primary source for solid fuel, nowadays the number of trees has decreased dramatically. Sustainable woody biomass sources like agro-residues, leaf litter, herbaceous biomass or waste from wood processing were offered. Those raw biomasses have an improper solid fuel as high moisture content, irregular size and shape and low bulk density. These cause problems with storage, transportation and combustion efficiency. Jatropha shell waste blended with Seed cake biochar was explored for the opportunity for producing pellets. The mixture of Seed cake biochar and Jatropha shell of 100, 75, 50, 25 and 0% each, particle sizes of 2 and 4 mm, and amount of adding water of 15% and 25% were evaluated
