A Comparative Analysis of Combustion Properties of Briquettes Produced From Sawdust Particles, Palm Fruit Shell And Rice Husk

Abstract

Briquetting is one way to efficiently use existing resources. This involves collecting combustible waste and compressing it into a convenient form of solid fuel that can be burned like wood or charcoal. Biomass briquettes are one of the proven ways to get energy from waste. Excessive use of fossil fuels, firewood and natural gas is causing serious environmental problems and deforestation. This study focused on comparing the combustion properties of briquettes made from sawdust particles, coconut husks, and rice husks. Cassava starch was used as the binder in a weight ratio of 100:15 and the flammability of the obtained palm fruit briquettes was determined. The calorific value of the briquettes was measured using a bomb calorimeter. The average moisture content and average ash content of the sawdust briquettes were 5.04% and 3.85%, respectively. Coconut fruit shell briquettes have the highest average percentage of volatile substances at 17.45%. Sawdust briquettes had the highest average proportion of fixed carbon, with average calorific values ​​of 80.95% and 26,918.02 kcal/kg, respectively. These results showed that the obtained briquettes had good combustion properties and were suitable for domestic use and small-scale industry, compared with the literature
