A Study of the Effect of Mixture Material in Coconut Shell Charcoal Briquette on Mechanical and Thermal property

Abstract

The objective of this research was to study the mechanical and thermal properties of the coconut shell charcoal briquette. The charcoal briquettes were prepared from charcoal powders mixed with an agricultural waste or community enterprise residues such as corn tree peanut shell and egg shell. The 20%wt latex glue of total raw material weight was used as a binder. After that, the 8 experimental conditions were designed for the charcoal briquettes properties study such as compressive resistance, bending resistance moisture and heat energy. From the research, it was found that the prepared charcoal briquettes from the mixture of coconut shell charcoal powders, corn tree and peanut shell at 50:25:25 exhibited 5.678 kN/mm² of the average compressive resistance, 1.125 kN/mm² of the average bending resistance, 5.596% of the average moisture and 5,515.33 Cal/g of the highest heat energy, respectively. Therefore, these results indicated that this condition was an appropriate condition in the application. Afterward, an ANOVA method was applied in the statistical variance analysis at significance level 0.05 of compressive resistance, bending resistance, moisture and heat energy. The results present a significant difference of the 8 experimental conditions.
