Description
This research aims to study the cassava biomass fuel pellets prepared by cold compressed techniques with high pressure. Cassava chips were ground and sieved in the grain size of 150-300, 300-2000 and >2000 μm and are compressed with 8, 10, 12, 14 and 16 tons/cm${}^2$. The dimension of cassava fuel pellets is 4 cm in diameter and 1.5 cm in thickness. The results show that the heat of cassava fuel pellets, measured with bomb calorie meter, has a heating value of 3,790 Kcal/Kg, the compressive strength is correlated with the size and the pressure applied compressive cassavas were not significant. (The grain size of 150-300 and 300-2000 μm are compressed at high pressure from 10 - 16 tons/cm${}^2$, which show that they have high compressive strength.) The cost of fuel pellets is equal to 0.12 baht per pellets. In this research, the most effective of biomass fuel pellets is biomass fuel pellets which has grain size >2000 μm and with pressure of 16 tons/cm${}^2$ and biomass fuel pellets with minimum burn rate is biomass fuel pellets with grain size >2000 μm and with pressure of 16 tons/cm${}^2.$ Our results show that the fuel pellets made from this study have the potential to be used as a household fuel to substitute charcoal which is scarce and more expensive.
