Determination of the Calorific Value of Briquettes Made from Pinus caribae and Eucalyptus citirodora

This analysis calculated the calorific value of briquettes made from Pinus caribaea and Eucalyptus citirodora. A sawmill in Buruku, Kaduna State, provided samples of sawdust. Briquettes were made in a manually controlled hydraulic briquette system with binder in 50:50, 60:40, and 70:30 percentage mixing ratios (starch: binder). There were three (3) replicates in each mixing proportion, for a total of eighteen items. To assess the energy content of the samples, calorific tests were performed using the Gallenkhamp Calorimeter. As compared to briquettes made from 100 percent pure sawdust, the results showed that adding starch in different proportions improves the average calorific value (Control). The effect of variation in the different proportions of binder on the calorific value is also highly significant at P0.05, according to the results of the Analysis of Variance (ANOVA). The physical properties of the materials used to make briquettes have an effect on the physical properties of the briquettes used in this research, such as moisture content and density.
